In May 1903, a newly drilled natural gas well was found to contain a nonflammable gas. Researchers at the University of Kansas found the “Dexter gas” contained only 15 percent methane and 72 percent nitrogen, causing the gas to be nonflammable. In addition they discovered helium within an “inert residue” in the gas and, after expanding their research to other wells throughout Kansas, Missouri, and Oklahoma, published a paper in 1907 saying that helium could be extracted from natural gas. Helium did not have any practical applications at the time, but by 1917 the federal government was sponsoring extensive research into the possibility of using helium in airships.

During these years he founded the Cellulose Products Company demonstrating that cellulose acetate could be used in producing nonflammable wire insulation and artificial silk. The company didn't do well financially, and when it was dissolved, Eastman Kodak purchased the company's patents for the first nonflammable motion picture film and the Lustron Company bought the artificial silk patents becoming the only American manufacturer of acetate silk. He collaborated with MIT and William Hultz Walker of the MIT Chemistry department, forming a partnership, Little & Walker, which lasted from 1900 to 1905, while both MIT and Little's company were still located in Boston. The partnership dissolved in 1905 when Walker dedicated his full-time to being in charge of the new Research Laboratory of Applied Chemistry at MIT.

Solid-state battery technology is believed to deliver higher energy density (2.5x), by enabling lithium metal anodes. They may avoid the use of dangerous or toxic materials found in commercial batteries, such as organic electrolytes. Because most liquid electrolytes are flammable and solid electrolytes are nonflammable, solid-state batteries are believed to have lower risk of catching fire. Fewer safety systems are needed, further increasing energy density.

Halothane was first synthesized by C. W. Suckling of Imperial Chemical Industries in 1951 in Widnes and was first used clinically by M. Johnstone in Manchester in 1956. It became popular as a nonflammable general anesthetic replacing other volatile anesthetics such as trichloroethylene, diethyl ether and cyclopropane. In many parts of the world it has been largely replaced by newer agents since the 1980s but is still widely used in developing countries because of its lower cost. A meter for measuring halothane.

It offers energy densities as high as 290 Wh/L and 224 Wh/kg and charge/discharge rates of 1C with a lifetime of 100 - 1000 charge cycles. The battery employs only nonflammable materials and neither ignites on contact with air nor risks thermal runaway. This eliminates waste-heat storage or fire- and explosion- proof equipment, and allows closer cell packing. The company claimed that the battery required half the volume of lithium-ion batteries and one quarter that of sodium–sulfur batteries.

Hindenburg was originally designed for helium, heavier than hydrogen but nonflammable. In the 1920s the United States possessed a monopoly on the production of helium, obtained as a byproduct of natural gas production. The US Congress banned its export under the Helium Act (1925) in an effort to conserve helium for use in US Navy airships. Eckener expected this ban to be lifted, but to save helium the design was modified to have double gas cells (an inner hydrogen cell protected by an outer helium cell).

To prevent children from getting burned, water temperature must not be set too high when taking baths or washing hands, nonflammable sleepwear should be worn, back burners should be used when cooking something on the stove, and hot foods, drinks, and irons should be kept away from the edge of counter and table. Oven mitts and potholders must be used in handling hot containers. Care should be taken when taking hot foods out of microwave ovens, and covers should be opened gently to reduce the risk of steam burns.

Neon, like all noble gases, has a full alt=An atomic shell diagram with neon core, 2 electrons in the inner shell and 8 in the outer shell. The noble gases are colorless, odorless, tasteless, and nonflammable under standard conditions. They were once labeled group 0 in the periodic table because it was believed they had a valence of zero, meaning their atoms cannot combine with those of other elements to form compounds. However, it was later discovered some do indeed form compounds, causing this label to fall into disuse.

Freon ( ) is a registered trademark of The Chemours Company, which uses it for a number of halocarbon products. They are stable, nonflammable, low toxicity gases or liquids which have generally been used as refrigerants and as aerosol propellants. These include the chlorofluorocarbons (CFCs) that cause ozone depletion and HCFCs (such as chlorodifluoromethane). Not all refrigerants of this type are labelled as "Freon" since Freon is a brand name for the refrigerants R-12, R-13B1, R-22, R-410A, R-502, and R-503 manufactured by The Chemours Company.

The injectors in a fuel injection system are check valves with a high opening pressure (5–8 bar). Check valves are also often used when multiple gases are mixed into one gas stream. A check valve is installed on each of the individual gas streams to prevent mixing of the gases in the original source. For example, if a fuel and an oxidizer are to be mixed, then check valves will normally be used on both the fuel and oxidizer sources to ensure that the original gas cylinders remain pure and therefore nonflammable.

Probable maximum loss (PML) is a term used in the insurance industry as well as commercial real estate. Although the definition is not consistent in the insurance industry, it is generally defined as the value of the largest loss that could result from a disaster, assuming the normal functioning of passive protective features (e.g. firewalls, nonflammable materials, flood defences etc.) and proper functioning of most (perhaps not all) active suppression systems (e.g. sprinklers). This loss estimate is always less than (or in rare cases, equal to) the maximum foreseeable loss, which assumes the failure of all active protective features.

To eliminate the threat of fire, Clark, Frank Scherb and William B. Smith created a "factory" that made nonflammable plastic scintillator disks, whose thickness was and whose diameter was approximately . After a switch to plastic in the late spring of 1956, the experiment ran continuously. Its findings were reported in Nature and the Physical Review. The most important results were summarized by Rossi as: As the Agassiz experiment came to an end, the group realized that observations near the equator and in the southern hemisphere were needed to extend their conclusion that air shower arrival directions are nearly isotropic.

It is used in many consumer products that require pressurized gas because it is inexpensive and nonflammable, and because it undergoes a phase transition from gas to liquid at room temperature at an attainable pressure of approximately 60 bar (870 psi, 59 atm), allowing far more carbon dioxide to fit in a given container than otherwise would. Life jackets often contain canisters of pressured carbon dioxide for quick inflation. Aluminium capsules of are also sold as supplies of compressed gas for air guns, paintball markers/guns, inflating bicycle tires, and for making carbonated water. Rapid vaporization of liquid carbon dioxide is used for blasting in coal mines.

While the fire bore marked similarities to the 1957 fire, the level of contamination was less severe because the HEPA filters in the exhaust system did not burn through (after the 1957 fire, the filter material was changed from cellulose to nonflammable fiberglass). Had the filters failed or the roof (which sustained heavy fire damage) been breached, the release could have been more severe than the 1957 fire. About of plutonium was in the storage area where the fire occurred, and about total plutonium was in building 776/777. The 1969 fire released 13-62 mCi () of plutonium, about 1/1000th as much as was released in the 1957 fire.

Tetrachloroethene, or Perchloroethene, also called PCE, is a chemical solvent used as a dry cleaning agent and a degreaser. On the New York State Department of Environmental Conservation's website, in its Glossary of Environmental Cleanup Terms, the chemical is described as being “a clear, colorless, nonflammable liquid with a characteristic odor.” The main types of exposure are through inhalation of the vapor, which can come from contaminated soil or water, and ingestion of contaminated water. Chronic exposure to the chemical has been shown to cause vision deficiencies. The toxicity of the chemical is recorded as being “moderate to low,” but there are some severe health risks.

Dry ice blasting used to clean a rubber mold Dry ice blasting is a form of carbon dioxide cleaning, where dry ice, the solid form of carbon dioxide, is accelerated in a pressurized air stream and directed at a surface in order to clean it. The method is similar to other forms of media blasting such as sand blasting, plastic bead blasting, or sodablasting in that it cleans surfaces using a media accelerated in a pressurized air stream, but dry ice blasting uses dry ice as the blasting medium. Dry ice blasting is nonabrasive, non- conductive, nonflammable, and non-toxic. Dry ice blasting is an environmentally responsible cleaning method.

2, line 30 The clear water or mineral oil can optionally be coloured with transparent dyes. Common wax has a density much lower than that of water and would float on top at any temperature. However, carbon tetrachloride is heavier than water (also nonflammable and miscible with wax) and is added to the wax to make its density at room temperature slightly higher than that of the water. When heated, the wax mixture becomes less dense than the water, because the wax expands more than water when both are heated.p. 1, lines 40 & 45 It also becomes fluid, and blobs of wax ascend to the top of the device where they cool (which increases their density relative to that of the water) and then they descend.p.

Stonehaven Fireballs Ceremony 2003Catalan Sun Goddess from the Hogmanay Street Party, Edinburgh 2005 An example of a local Hogmanay custom is the fireball swinging that takes place in Stonehaven, Aberdeenshire, in northeast Scotland. This involves local people making up "balls" of chicken wire filled with old newspaper, sticks, rags, and other dry flammable material up to a diameter of , each attached to about of wire, chain or nonflammable rope. As the Old Town House bell sounds to mark the new year, the balls are set alight and the swingers set off up the High Street from the Mercat Cross to the Cannon and back, swinging the burning balls around their heads as they go. At the end of the ceremony, any fireballs that are still burning are cast into the harbour.

In legal terms of the United States, a powered industrial truck (PIT) is a specialized motor vehicle ( truck) defined in several standards: ANSI B56.1-1969 (PIT is a “mobile, power propelled truck used to carry, push, pull, lift, stack, or tier material.”), the OSHA 29 CFR 1910.178 “Powered Industrial Trucks” regulation "Safety and Health Topics / Powered Industrial Trucks - Forklifts" and its standard interpretations Standard Interpretations: Standard Number > 1910 > 1910.178 depending on industry type: general industry, marine terminals, longshoring, and construction. OSHA defines PITs as "forklifts, tractors, platform lift trucks, motorized hand trucks, and other specialized industrial trucks powered by electric motors or internal combustion engines." The OSHA regulation specifically excludes "compressed air or nonflammable compressed gas-operated industrial trucks, nor to farm vehicles, nor to vehicles intended primarily for earth moving or over-the-road hauling".

It included a 12-mile (19 km) trestle on wooden pilings across the Great Salt Lake. Opened in 1904, this line cut off the line, eliminated 3,919 degrees of curvature, and removed of climb from the route, thus decreasing the steepest SP grade east of Lucin from 90 feet per mile to 21. But many other sections of the original 1860s grade were harder to improve on, notably over the Sierra Nevada between Colfax, California, and Reno, Nevada. The newer second track follows a better route here and there, but the original route changed little (except for the removal of the wooden snowsheds, or their replacement by nonflammable concrete ones) until the 1993 abandonment of the 6.7-mile section of the Track No. 1 crossing of the summit between Norden and Eder which includes the original Summit Tunnel (No. 6). Traffic was sent instead over the easier-to-maintain Track No. 2 and through the tunnel called “The Big Hole” (No.
