A gas explosion is the ignition of a mixture of air and flammable gas, typically from a gas leak. [1] ... this range is 5-15% and 1.4-7.6% gas to air, ...
Dusts also have upper and lower explosion limits, though the upper limits are hard to measure and of little practical importance. Lower flammability limits for many organic materials are in the range of 10–50 g/m 3 , which is much higher than the limits set for health reasons, as is the case for the LEL of many gases and vapours.
The Hindenburg disaster is an example of a large hydrogen explosion. Hydrogen safety covers the safe production, handling and use of hydrogen, particularly hydrogen gas fuel and liquid hydrogen. Hydrogen possesses the NFPA 704's highest rating of four on the flammability scale because it is flammable when mixed even in small amounts with ...
On September 13, 2018, excessive pressure in natural gas lines owned by Columbia Gas of Massachusetts caused a series of explosions and fires to occur in as many as 40 homes, with over 80 individual fires, in the towns of Lawrence, Andover, and North Andover, all within the Merrimack Valley, in Massachusetts, United States.
The injured range in age from 18 to 74, police said. ... Preliminary investigations suggest the explosion may have involved liquefied petroleum gas linked to a suspected grill malfunction, though ...
On 4 June 1989, a gas explosion destroyed two trains (37 cars and two locomotives) in the USSR. ... the final explosion was in the range of 4,000–5,000 kg TNT. [74]
Only pure chemicals belong here not fuel air mixtures to be here a gas must have an upper explosive limit of 100%. Pages in category "Explosive gases" The following 9 pages are in this category, out of 9 total.
A lean flashover (sometimes called rollover) is the ignition of the gas layer under the ceiling, leading to total involvement of the compartment. The air–fuel ratio is at the bottom region of the flammability range (i.e. lean). A rich flashover occurs when the flammable gases are ignited while at the upper region of the flammability range (i ...
