The incident was broadcast live on radio and filmed. Ignition of leaking hydrogen is widely assumed to be the cause, but later investigations pointed to the ignition of the aluminized fabric coating by static electricity. But the damage to hydrogen's reputation as a lifting gas was already done and commercial hydrogen airship travel ceased. Hydrogen is still used, in preference to non-flammable but more expensive helium, as a lifting gas for weather balloons.

The esters decompose to release carbon dioxide and regenerate the phosphoric acid catalyst. In the gas phase, the release of non-flammable carbon dioxide helps to dilute the oxygen of the air and flammable decomposition products of the material that is burning. In the condensed phase, the resultant carbonaceous char helps to shield the underlying polymer from attack by oxygen and radiant heat. Use as an intumescent is achieved when combined with starch-based materials such as pentaerythritol and melamine as expanding agents.

ClF3 is a very strong oxidizing and fluorinating agent. It is extremely reactive with most inorganic and organic materials, such as glass, and will initiate the combustion of many otherwise non-flammable materials without any ignition source. These reactions are often violent, and in some cases explosive. Vessels made from steel, copper, or nickel are not consumed by ClF3 because a thin layer of insoluble metal fluoride will form, but molybdenum, tungsten, and titanium form volatile fluorides and are consequently unsuitable.

Silicone oils are primarily used as lubricants, thermic fluid oils or hydraulic fluids. They are excellent electrical insulators and, unlike their carbon analogues, are non-flammable. Their temperature stability and good heat-transfer characteristics make them widely used in laboratories for heating baths ("oil baths") placed on top of hotplate stirrers, as well as in freeze-dryers as refrigerants. Silicone oil is also commonly used as the working fluid in dashpots, wet-type transformers, diffusion pumps and in oil- filled heaters.

However, after the nitrogen evaporates, it has to be refilled. In the realm of personal computers, this method of cooling is seldom used in contexts other than overclocking trial-runs and record-setting attempts, as the CPU will usually expire within a relatively short period of time due to temperature stress caused by changes in internal temperature. Although liquid nitrogen is non- flammable, it can condense oxygen directly from air. Mixtures of liquid oxygen and flammable materials can be dangerously explosive.

The Expansion Engine can offer significant advantages here, in particular for lower power ratings of 2 to 100 kW: with expansion ratios of 1:5, the theoretical efficiency reaches 15%, which is in the range of ORC systems. The Expansion Engine uses water as working fluid which is simple, cheap, non-toxic, non-flammable and non-corrosive. It works at pressure near and below atmospheric, so that sealing is not a problem. And it is a simple machine, implying cost effectiveness.

Since before WWII AsH3 was proposed as a possible chemical warfare weapon. The gas is colorless, almost odorless, and 2.5 times denser than air, as required for a blanketing effect sought in chemical warfare. It is also lethal in concentrations far lower than those required to smell its garlic- like scent. In spite of these characteristics, arsine was never officially used as a weapon, because of its high flammability and its lower efficacy when compared to the non-flammable alternative phosgene.

It is also designed to be non-flammable (the reaction cannot be triggered by a burning fuse or electricity), although its explosion can cause other flammable material to ignite. Because it is sold as two separate components, it can be transported and sold in many places without the legal restrictions that would otherwise apply to explosives. The term tannerite is often used to refer to the mixture itself, and other reactive targets and combination explosives are often generically referred to as tannerite.

Aeros has developed a technology to avoid the need for ballast, which they call "control of static heaviness (COSH)". The main gas bag is inflated with helium to create lift for takeoff, then on landing some of the gas is re-compressed into a storage tank to partially deflate the gas bag and reduce lift. Worldwide Aeros was awarded a patent for this system in May 2015. It internally ballasts the non-flammable helium into the aircraft’s helium pressure envelopes (HPEs), helping the vehicle manage buoyancy.

Performic acid is non-toxic; it does irritate the skin, but less so than peracetic acid. Concentrated acid (above 50%) is highly reactive; it readily decomposes upon heating, and explodes upon rapid heating to 80–85 °C. It may ignite or explode at room temperature when combined with flammable substances, such as formaldehyde, benzaldehyde, or aniline, and explodes violently upon addition of metal powders. For this reason, spilled performic acid is diluted with cold water and collected with neutral, non-flammable inorganic absorbents, such as vermiculite.

In 2016, Trane was selected to provide replacement chillers for the tunnel's cooling network. The York chillers were decommissioned and four "next generation" Trane Series E CenTraVac large- capacity (2600 kW to 14,000 kW) chillers were installed—two located in Sangatte, France, and two at Shakespeare Cliff, UK. The energy-efficient chillers, using Honeywell's non-flammable, ultra-low GWP R1233zd(E) refrigerant, maintain temperatures at , and in their first year of operation generated savings of 4.8 GWh—approximately 33%, equating to €500,000 ($585,000)—for tunnel operator Getlink.

Services opened to the public on 24 February 1906 from Angel to Aldwych, with a ceremonial opening by the chairman of the Highways Committee. The first journey took 12 minutes northbound and 10 minutes to return, despite horse-drawn vehicles also using the roads on the surface part of the route. On 16 November that year the routes were extended north from The Angel to Highbury station. Special trams were constructed from non-flammable materials – wooden trams, common on other routes, were not permitted through the subway.

The Xella Group with headquarters in Duisburg, Germany, develops, manufactures and markets building and insulation materials. With its Ytong, Silka and Hebel brands, Xella is one of the world's largest manufacturers of autoclaved aerated concrete and calcium silicate units. The Multipor brand stands for non-flammable mineral insulation boards. Xella is one of just a few European building materials companies to operate its own Research and Development Center which focuses its work on three main areas: Product and process research, applied research and construction physics.

In the late 1920s, air conditioning and refrigeration systems employed compounds such as ammonia (NH3), chloromethane (CH3Cl), propane, and sulfur dioxide (SO2) as refrigerants. Though effective, these were toxic, flammable or explosive. The Frigidaire division of General Motors, at that time a leading manufacturer of such systems, sought a non-toxic, non- flammable alternative to these refrigerants. Kettering, the vice president of General Motors Research Corporation at that time, assembled a team that included Midgley and Albert Leon Henne to develop such a compound.

Prominent among these was the new aluminum and fiberglass outward-opening hatch, which the crew could open in seven seconds from within, and the pad crew in ten seconds from outside. Other changes included replacement of aluminum tubing in the high-pressure oxygen system with stainless steel, replacement of flammable materials with non-flammable (including changing plastic switches for metal ones) and, for crew protection in the event of a fire, an emergency oxygen system to shield them from toxic fumes, as well as firefighting equipment.

Silica gel is non- toxic, non-flammable, and non-reactive and stable with ordinary usage. It will react with hydrogen fluoride, fluorine, oxygen difluoride, chlorine trifluoride, strong acids, strong bases, and oxidizers. Silica gel is irritating to the respiratory tract and may cause irritation of the digestive tract, and dust from the beads may cause irritation to the skin and eyes, so precautions should be taken. Crystalline silica dust can cause silicosis, but synthetic amorphous silica gel is indurated so does not cause silicosis.

Natural fiber will singe rather than melt or burn readily, and flame-retardant fiber generally has a very high melting point and is intrinsically non-flammable. Many pilots also advise their passengers to wear similar protective clothing that covers their arms and legs, as well as strong shoes or boots that offer good ankle support. Finally, some balloon systems, especially those that hang the burner from the envelope instead of supporting it rigidly from the basket, require the use of helmets by the pilot and passengers.

By the early 20th century, cumulative New York City building code changes and additions required a solid brick proscenium wall, extending from the cellar to the roof, to minimize the risk of a stage fire spreading into the auditorium. Any openings in the wall, such as the large opening made by the proscenium arch itself, required special fire blocking facilities. Proscenium arches were equipped with non-flammable fire curtains; other openings in the proscenium wall required self-closing fire-resistant doors. Heat activated sprinkling systems were required for the fly space above the stage.

A modern R-134a hermetic refrigeration compressor The first air conditioners and refrigerators employed toxic or flammable gases, such as ammonia, methyl chloride, or propane, that could result in fatal accidents when they leaked. Thomas Midgley, Jr. created the first non-flammable, non- toxic chlorofluorocarbon gas, Freon (R-12), in 1928. The name is a trademark name owned by DuPont for any chlorofluorocarbon (CFC), hydrochlorofluorocarbon (HCFC), or hydrofluorocarbon (HFC) refrigerant. The refrigerant names include a number indicating the molecular composition (e.g., R-11, R-12, R-22, R-134A).

The gas composition must be considered, because natural gas appliances are designed for gas with a heating value of about 1,000 BTU (British thermal units) per cubic foot, or nearly pure methane. If the gas contains more than a few percent non-flammable gases such as nitrogen or carbon dioxide, either these will have to be removed or it will have to be blended with higher-BTU gas to achieve pipeline quality. If the methane composition of the coalbed gas is less than 92%, it may not be commercially marketable.

The wounded were buried alive, and those who were still moving or crying were dictated to be killed by military shovels. The entire boat was also instructed to be burned down aside from the only 3-blade propeller non- flammable to gasoline, then all buried in sand to destroy all the evidence right away. The last victim, a little boy being hidden underneath a board cell was also found and executed by order without exception. The guarding sergeant of the BHQ company counted the bodies as more than nineteen.

It is built of a semi-rigid airbag with several separated gas compartments, which would permit lift even if one or more of the gas compartments was damaged. Three cabins are hung below the airship: at the front is the pilot house, in the middle is the general quarters, and at the rear is the engine. A non-flammable gas is used for lift, and a single gas- powered engine provides forward momentum. Storage batteries, coupled with an electric motor, are used as backup power in the event of main engine failure.

A reinforced, fireproof cabinet for dangerous chemicals Mitigating the risks associated with hazardous materials may require the application of safety precautions during their transport, use, storage and disposal. Most countries regulate hazardous materials by law, and they are subject to several international treaties as well. Even so, different countries may use different class diamonds for the same product. For example, in Australia, anhydrous ammonia UN 1005 is classified as 2.3 (toxic gas) with subsidiary hazard 8 (corrosive), whereas in the U.S. it is only classified as 2.2 (non-flammable gas).

Exposure to very high concentrations of gaseous ammonia can result in lung damage and death. Ammonia is regulated in the United States as a non-flammable gas, but it meets the definition of a material that is toxic by inhalation and requires a hazardous safety permit when transported in quantities greater than 13,248 L (3,500 gallons).Is Anhydrous Ammonia covered under the Hazardous Materials Safety Permit Program? from the website of the United States Department of Transportation (DOT) Liquid ammonia is dangerous because it is hygroscopic and because it can cause caustic burns.

They are sold as being stronger, more flexible than cement, steel or bricks and also non-flammable, waterproof and hurricane resistant. "InnoVida technology would have a far-reaching impact on the booming construction industry by reducing its dependence on cement, wood, steel and labor while ensuring speedy environment-friendly construction. 'We hope our building on Al Reem Island will be the first such structure to inspire other builders to adapt this technology which will go a long way in saving energy and construction time.'" - Dr. Abdallah Shaaban, Chief Executive Officer of Tameer Abu Dhabi.

Chloroform is a colorless liquid that is non-flammable. This chemical can be found in floor polishing substances and pesticides. Chloroform is recognized carcinogen, meaning it can cause cancer if one is exposed to it for a long period of time. It is ranked in the top 10% of the most hazardous compounds to human health and the environment, based on how toxic it is when ingested or inhaled, how it affects human health, cancer and noncancer risk scores through air and water, and how toxic it is to the environment.

In addition it is odourless or pleasant to inhale; safe for all ages and in pregnancy; not metabolised; rapid in onset and offset; potent; and safe for exposure to operating room staff. It is also cheap to manufacture; easy to transport and store, with a long shelf life; easy to administer and monitor with existing equipment; stable to light, plastics, metals, rubber and soda lime; non-flammable and environmentally safe. None of the agents currently in use are ideal, although many have some of the desirable characteristics. For example, sevoflurane is pleasant to inhale and is rapid in onset and offset.

Some types were provided with soapstone or iron plates which were heated during the preliminary cooking on the stove and then placed in the fireless cooker either over or under the cooking pot. In these types, a non-flammable insulating material was used. A successful home-made strategy was to take a box so large that the cooking pot when placed in it could be surrounded by a thick layer of non-conducting material, such as hay, excelsior or crumpled paper. A cushion was placed over the pot and a tight-fitting lid was placed over all.

Organic radical batteries are much more environmentally friendly than Li-ion batteries because ORBs do not contain any metals that pose the problem of proper disposal. ORBs are non-toxic and non- flammable and do not require additional care when handling. Burning nitroxide radical polymers yields carbon dioxide, water, and nitrogen oxide without ash or odor. While being environmentally friendly, they have properties that are otherwise comparable to Li-ion batteries: ORBs have a theoretical capacity of 147 mA h g⁻¹, which is slightly higher than that of Li-ion batteries with 140 mA h g⁻¹.

Many industrial products, including heat pumps that operate on a refrigerant and propellant aerosols, require non-flammable fluids capable of passing easily from gaseous state to liquid state and having significant latent heat. Historically, chlorofluorocarbons (CFCs) were used in these applications, but we discovered in the 1970s the deleterious effect of these gases on the ozone layer, which is rewarded by a Nobel Prize in Chemistry in 1995. The Montreal Protocol, signed in 1985 by many states and entered into force in 1989, decided to phase out CFCs. The use of hydrofluorocarbons (HFCs) then developed as a replacement.

Global warming: Difluoroethane (HFC-152a), trifluoroethane (HFC-143a), and completely non- flammable tetrafluoroethane (HFC-134a) are potent greenhouse gases. According to the Intergovernmental Panel on Climate Change (IPCC), the global warming potential (GWP) of HFC-152a, HFC-143a, and HFC-134a are 124, 4470, and 1430, respectively. GWP refers to global warming effect in comparison to CO2 for unit mass. 1 kg of HFC-152a is equivalent to 124 kg of CO2 Ozone layer depletion: Gas dusters sold in many countries are ozone safe as they use "zero ODP" (zero ozone depletion potential) gases; tetrafluoroethane, for example, has insignificant ODP.

Supercritical carbon dioxide is used to remove organochloride pesticides and metals from agricultural crops without adulterating the desired constituents from the plant matter in the herbal supplement industry.Department of Pharmaceutical Analysis, Shenyang Pharmaceutical University, Shenyang 110016, China Supercritical carbon dioxide can be used as a more environmentally friendly solvent for dry cleaning over traditional solvents such as hydrocarbons, including perchloroethylene. Supercritical carbon dioxide is used as the extraction solvent for creation of essential oils and other herbal distillates. Its main advantages over solvents such as hexane and acetone in this process are that it is non-toxic and non- flammable.

Supercritical is chemically stable, reliable, low-cost, non-toxic, non-flammable and readily available, making it a desirable candidate working fluid. Supercritical CO2 is used as the working fluid in high efficiency domestic water heat pumps. Manufactured and widely used, heat pumps are also commercially available for domestic and business heating and cooling. While some of the more common domestic water heat pumps remove heat from the space in which they are located, such as a basement or garage, the CO2 heat pump water heaters are typically located outside, where they remove heat from a building to the outside air.

Liquid seal flame arrestors are liquid barriers following the principle of a siphon where the liquid stops the entering deflagration and/or detonation and extinguishes the flame, they work by bubbling the gas through a non-flammable and ideally non-gas-absorbing liquid, which is typically water. They stop the flame by preventing it from reaching the submerged intake. These devices are normally very effective at stopping flashbacks from reaching the protected side of the system. They have the disadvantages of only working in one orientation and tend to be much larger than dry type arrestors.

Gus Grissom's and Roger Chaffee's headstones during the NASA Day of Remembrance ceremony in 2013 Shortly after the AS-204 fire in 1967, NASA Associate Administrator for Manned Spaceflight George Mueller announced the mission would be officially designated as Apollo 1. The capsule underwent a significant redesign as a result of the disaster. The atmosphere in the cabin was changed from 100% oxygen to a 60% oxygen and 40% nitrogen environment at launch. The astronauts' spacesuits, originally made of nylon, were changed to beta cloth, a non- flammable, highly melt-resistant fabric woven from fiberglass and coated with Teflon.

The first half of the 1860s was a period of strong growth for Brisbane. Immigration boosted the population dramatically (more than doubling between 1861 and 1864 to over 12,000) and many substantial public and private buildings were constructed during this time. The permanent nature of the buildings was also partly influenced by provisions in the Municipalities Act 1864, which required brick or stone construction and non-flammable roofing material in designated first class building areas. Harris Terrace, circa 1869 In 1865 Harris commissioned architect James Cowlishaw to design a terrace building of six self-contained residences on the south-west corner of George and Margaret streets.

Its physical properties are highly favorable for cooling, refrigeration, and heating purposes, having a high volumetric cooling capacity. Due to the need to operate at pressures of up to 130 bar (1880 psi), systems require highly resistant components that have already been developed for mass production in many sectors. In automobile air conditioning, in more than 90% of all driving conditions for latitudes higher than 50°, R744 operates more efficiently than systems using R134a. Its environmental advantages (GWP of 1, non-ozone depleting, non-toxic, non-flammable) could make it the future working fluid to replace current HFCs in cars, supermarkets, and heat pump water heaters, among others.

Martinizing LinkedIn profile The concept of One Hour Martinizing was pioneered by a New York chemist named Henry Martin in 1949. At the time, dry cleaning was done with flammable solvents, so the plants were located remotely from the storefronts. A customer would drop off their cleaning "in town", the garments would travel to the production facility to be cleaned and pressed, then they would return to the store several days later for pickup. By using a non-flammable solvent, the use of which was discovered by Martin, dry cleaning plants could now be located much more conveniently, and the process could be carried out in a much more timely manner.

Commercial refrigerator and freezer units, which go by many other names, were in use for almost 40 years prior to the common home models. They used gas systems such as ammonia (R-717) or sulfur dioxide (R-764), which occasionally leaked, making them unsafe for home use. Practical household refrigerators were introduced in 1915 and gained wider acceptance in the United States in the 1930s as prices fell and non-toxic, non-flammable synthetic refrigerants such as Freon-12 (R-12) were introduced. However, R-12 damaged the ozone layer, causing governments to issue a ban on its use in new refrigerators and air-conditioning systems in 1994.

British World War II 4-inch naval illuminating shell, showing time fuze (orange, top), illuminating compound (green) and parachute (white, bottom) Modern illuminating shells are a type of carrier shell or cargo munition. Those used in World War I were shrapnel pattern shells ejecting small burning 'pots'. A modern illumination shell has a time fuze that ejects a flare 'package' through the base of the carrier shell at a standard height above ground (typically about 600 metres), from where it slowly falls beneath a non-flammable parachute, illuminating the area below. The ejection process also initiates a pyrotechnic flare emitting white or 'black' infrared light.

In 2006, batteries from Apple, HP, Toshiba, Lenovo, Dell and other notebook manufacturers were recalled because of fire and explosions. The Pipeline and Hazardous Materials Safety Administration (PHMSA) of the U.S. Department of Transportation has established regulations regarding the carrying of certain types of batteries on airplanes because of their instability in certain situations. This action was partially inspired by a cargo bay fire on a UPS airplane. One of the possible solutions is in using safer and less reactive anode (lithium titanates) and cathode (lithium iron phosphate) materials — thereby avoiding the cobalt electrodes in many lithium rechargeable cells — together with non-flammable electrolytes based on ionic liquids.

Flurothyl (Indoklon) (IUPAC names: 1,1,1-trifluoro-2-(2,2,2-trifluoroethoxy)ethane or bis(2,2,2-trifluoroethyl) ether) is a volatile liquid drug from the halogenated ether family, related to inhaled anaesthetic agents such as diethyl ether, but having the opposite effects, acting as a stimulant and convulsant. A clear and stable liquid, it has a mild ethereal odor whose vapors are non-flammable. It is excreted from the body by the lungs in an unchanged state. Several compounds related to the halogenated ether anesthetics have similar convulsant effects rather than producing sedation, and this has been helpful in studying the mechanism of action of these drugs.

Isobutane is used as a refrigerant. Their use in refrigerators started in 1993 when Greenpeace presented the Greenfreeze project with the German company Foron. In this regard, blends of pure, dry "isobutane" (R-600a) (that is, isobutane mixtures) have negligible ozone depletion potential and very low global warming potential (having a value of 3.3 times the GWP of carbon dioxide) and can serve as a functional replacement for R-12, R-22 (both of these being commonly known by the trademark Freon), R-134a, and other chlorofluorocarbon or hydrofluorocarbon refrigerants in conventional stationary refrigeration and air conditioning systems. As a refrigerant, isobutane poses an explosion risk in addition to the hazards associated with non-flammable CFC refrigerants.

Dry ice is the solid form of carbon dioxide (CO2), a molecule consisting of a single carbon atom bonded to two oxygen atoms. Dry ice is colorless, non-flammable, with a sour zesty odor, and can lower the pH of a solution when dissolved in water, forming carbonic acid (H2CO3). Comparison of phase diagrams of carbon dioxide (red) and water (blue) as a log-lin chart with phase transitions points at 1 atmosphere At pressures below 5.13 atm and temperatures below (the triple point), CO2 changes from a solid to a gas with no intervening liquid form, through a process called sublimation.Above the triple point, CO2 goes through the more familiar transitions via a liquid phase.

This period also saw the introduction of non-flammable helium as a lifting gas by the United States, while the more dangerous hydrogen continued to be used since the United States had the only sources of the gas at that time, and would not export it. In 1919 the British airship R34 flew a double crossing of the Atlantic and in 1926 the Italian semi-rigid airship, Norge was the first aircraft confirmed to fly over the North Pole. The first American-built rigid airship, the , flew in 1923. The Shenandoah was the first to use helium, which was in such short supply that the one airship contained most of the world's reserves.

CO2 Technology requires the design of completely new high-pressure systems whereas so-called "drop-in solutions" (the adaptation of current systems to new substances) are potentially more cost-efficient. The Alliance for CO2 Solutions claims, however that the initial costs of CO2 systems will be around €5 higher than drop-in solutions and that over a car's life cycle, CO2 air conditioning systems will be more cost-efficient than any currently used or proposed new chemical blends. (see Arguments for CO2). has been classified as Safety Class A1 (low-toxic, non-flammable refrigerant) by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE)ASHRAE Standard 34 – the highest safety class possible.

Micrometeoroid impacts in Beta cloth Outside a Liquid Cooling and Ventilation Garment, pressure bladder, and restraint layer, the TMG for the A7L suit worn on the Moon and during the Skylab Program began with a layer of neoprene-coated nylon ripstop. This was the innermost layer of protection from micrometeoroids. Next, thermal radiation protection was provided by five layers of aluminized PET film (Mylar), alternating with four layers of nonwoven Dacron, which provided thermal spacing, followed by two layers of aluminized polyimide Kapton film and Beta cloth marquisette laminate. The outermost layer of PTFE (Teflon)-coated filament Beta cloth was non-flammable and provided abrasion protection from the notoriously abrasive lunar dust.

Because of its low density and incombustibility, helium is the gas of choice to fill airships such as the alt=The Good Year Blimp Because it is lighter than air, airships and balloons are inflated with helium for lift. While hydrogen gas is more buoyant, and escapes permeating through a membrane at a lower rate, helium has the advantage of being non- flammable, and indeed fire-retardant. Another minor use is in rocketry, where helium is used as an ullage medium to displace fuel and oxidizers in storage tanks and to condense hydrogen and oxygen to make rocket fuel. It is also used to purge fuel and oxidizer from ground support equipment prior to launch and to pre-cool liquid hydrogen in space vehicles.

The properties are listed by the National Trust of Trinidad and Tobago as examples of the "city's remarkable architectural heritage." Some of the buildings are in good condition, but others have been in need of repair, like Mille Fleurs, which was beginning to be restored in 2015. This period of construction of the Magnificent Seven occurred just after the turn of the 20th-century, following a "disastrous" fire of 1895 in Port of Spain, after which non-flammable materials like metal, concrete, and cast iron were used in the construction new buildings. George Brown of the Trinidad Trading Company, who built Mille Fleurs, did much of the rebuilding after the fire and is responsible for much of the metalwork used in the city at that time.

The 150 MW Andasol solar power station is a commercial parabolic trough solar thermal power plant, located in Spain. The Andasol plant uses tanks of molten salt to store solar energy so that it can continue generating electricity even when the sun isn't shining. Molten salt is used to transport heat in solar power tower systems because it is liquid at atmospheric pressure, provides a low-cost medium to store thermal energy, its operating temperatures are compatible with today's steam turbines, and it is non-flammable and nontoxic. Molten salt is also used in the chemical and metals industries to transport heat. The first commercial molten salt mixture was a common form of saltpeter, 60% sodium nitrate and 40% potassium nitrate. Saltpeter melts at 220 °C (430 °F) and is kept liquid at 290 °C (550 °F) in an insulated storage tank.

LPG is instrumental in providing off-the-grid refrigeration, usually by means of a gas absorption refrigerator. Blended of pure, dry propane (refrigerant designator R-290) and isobutane (R-600a) the blend "R-290a" has negligible ozone depletion potential and very low global warming potential and can serve as a functional replacement for R-12, R-22, R-134a and other chlorofluorocarbon or hydrofluorocarbon refrigerants in conventional stationary refrigeration and air conditioning systems. Such substitution is widely prohibited or discouraged in motor vehicle air conditioning systems, on the grounds that using flammable hydrocarbons in systems originally designed to carry non- flammable refrigerant presents a significant risk of fire or explosion. Vendors and advocates of hydrocarbon refrigerants argue against such bans on the grounds that there have been very few such incidents relative to the number of vehicle air conditioning systems filled with hydrocarbons.

Transportation of hazardous materials for commercial purposes in the USA is regulated by Code of Federal Regulations Title 49 - Transportation, (abbreviated 49 CFR). A cylinder containing 200 kPa (29.0 psig/43.8 psia) or greater at 20 °C (68 °F) of non-flammable, nonpoisonous compressed gas, and being transported for commercial purposes is classified as HAZMAT (hazardous materials) in terms of 49 CFR 173.115(b) (1). Cylinders manufactured to DOT standards or special permits (exemptions)issued by the Pipeline and Hazardous Materials Safety Administration and filled to the authorized working pressure are legal for commercial transport in the USA under the provisions and conditions of the regulations. Cylinders manufactured outside the USA may be transported under a special permit, and these have been issued for solid metal and composite cylinders with working pressures of up to 300 bar (4400 psi) by several manufacturers.

In May 2005, the island Patrol Uniform was introduced, consisting of a helmet, dark blue polo top and Bermudas for officers performing bicycle patrol duties on Pulau Ubin. These were introduced to project a softer image on the island where recreational activities abound, and to provide greater comfort for the officers in the humid outdoor weather. As part of a force-wide review of the police uniforms, the PCG adopted the new combat uniform similar to that currently worn by the Special Operations Command, albeit with a darker shade of blue. While they were introduced to overcome existing limitations of the current uniform, such as allowing for less hindrance in body movement due to the more relaxed fit, and its non-flammable properties, they met with opposition from some officers who feel it projects the wrong image to the general public, including its "technician" look.

Starting fluid is not recommended for regular use with some two-stroke engines because it does not possess lubricating qualities by itself. Lubrication for two-stroke engines is achieved using oil that is either mixed into the fuel by the user or injected automatically into the fuel supply; engines requiring premixed fuel that are run solely on starting fluid do not receive an adequate supply of lubrication to their crankcase and cylinder(s). Engines that haven't been run recently are especially vulnerable to damage from oil starvation; starting fluid, a strong solvent, tends to strip residual oil off of cranks and cylinder walls, further reducing lubrication during the period of fuel starvation. WD-40 was previously recommended for use on two stroke engines because it has lubricating qualities, but the formulation with non-flammable CO2 as propellant instead of propane no longer has the same propulsive effect.

In certain cases, TRPA regulations require ground cover to provide protection from soil erosion on disturbed soil. Ground cover may often be lawn or other landscaping, however site-specific native vegetation, or naturally occurring forest litter such as a thin layer of pine needles or wood chips is generally the environmentally preferable alternative, and is more cost-effective and easier to maintain. While some groups argue that utilizing pine needles and wood chips as ground cover up to the 30 foot perimeter of a structure is a violation of California Public Resources Code 4291 requiring defensible space in California, a ½ to covering of forest litter (duff layer) is not sufficient to carry a flame intense enough to burn structures from a distance of away. Regardless, TRPA staff and local fire groups are investigating possible non- flammable or flame-retardant alternatives to provide both soil protection and fire prevention.

Victor Rjesnjansky on A&E;'s Storage Wars: Texas often refers to his competitors, Ricky and Bubba, as "the Hindenburgs", a reference to their portly physique. In the Archer episode "Skytanic", which takes place on board an airship, Archer makes several references to the Hindenburg due to his paranoia about the airship catching fire, despite the airship's captain repeatedly telling him that the ship uses non-flammable helium. In an episode of The Amazing World of Gumball, while Gumball and Darwin escape from Molly's universe, they all jump upon an airship resembling the Hindenburg that then catches fire and crashes into a structural pylon, much like the disaster. In the Rocko's Modern Life episode "Feisty Geist," while visiting a fortune teller, Heffer Wolfe is told of his past lives, and one of them is of when he was a hungry passenger aboard the airship Hillenburger (also a play on the name of the show's creative director Stephen Hillenburg).

As part of a force-wide review of the police uniforms, the PCG adopted the new combat uniform similar to that worn by the Special Operations Command, albeit with a darker shade of blue. While they were introduced to overcome existing limitations of the current uniform, such as allowing for less-hindrance in body movement due to the more relaxed fit, and its non-flammable properties, they met with opposition from some officers who feel it projects the wrong image to the general public, including its "technician" look. Officers began to don the new combat uniform from 21 August 2006. In 2006, the Gurkha Contingent implemented its biggest change to its uniform since the adoption of the present uniform three decades ago, just prior to the commencement of the 61st Annual Meetings of the Boards of Governors of the International Monetary Fund and the World Bank Group as part of Singapore 2006.

A BLEVE need not be a chemical explosion, nor does there need to be a fire: however, if a flammable substance is subject to a BLEVE it may also be subject to intense heating, either from an external source of heat which may have caused the vessel to rupture in the first place or from an internal source of localized heating such as skin friction. This heating can cause a flammable substance to ignite, adding a secondary explosion caused by the primary BLEVE. While blast effects of any BLEVE can be devastating, a flammable substance such as propane can add significantly to the danger. 500px While the term BLEVE is most often used to describe the results of a container of flammable liquid rupturing due to fire, a BLEVE can occur even with a non-flammable substance such as water, liquid nitrogen,Liquid nitrogen BLEVE demo liquid helium or other refrigerants or cryogens, and therefore is not usually considered a type of chemical explosion.

Stryker at Fort Irwin National Training Center Throughout its years in service, the Stryker has undergone various survivability upgrades and received "kit" applications designed to improve the vehicle's ability to withstand attacks. The US Army plans to improve its fleet of Stryker vehicles with the introduction of improved semi- active suspension, modifications reshaping the hull into a shallow V-shaped structure, to protect against improvised explosive devices (IEDs). Also included are additional armor for the sides, redesigned hatches to minimize gaps in the armor, blast-absorbent, mine-resistant seating, non-flammable tires, an upgrade to the remote weapon station that allows it to fire on the go, increased 500 ampere electrical generation, a new solid-state power distribution system and data bus, and the automotive and power plant systems improvements to support one-fourth greater gross vehicle weight. The upgraded V-hull will be part of the new StrykShield situational awareness kit, which will address many of these upgrades.

One of the Typhon aliens, the Mimic, was inspired by the creature of the same name from Dungeons & Dragons, and was programmed to take the form of any object smaller than itself in the room, avoiding the use of scripted events and allowing the alien's artificial intelligence in the game's software decide what to replicate. Separately, one of the tools developed by Arkane was the psychoscope, which allows players to scan an alien and learn and then use its powers; when the programmers learned of this, they quickly found that having players be able to copy the Mimic's power created a depth of new gameplay options, such as taking the form of a small object to sneak into small places, or taking the form of a non-flammable object to roll through fire-laden areas. Enabling emergent gameplay in Prey allowed for speedrunners to take advantage of the game's tools, particularly the Gloo Cannon that is able to create platforms on surfaces to access areas Arkane did not intend to be accessed without other tools.
