A gas explosion is the ignition of a mixture of air and flammable gas, typically from a gas leak. [1] In household accidents, the principal explosive gases are those used for heating or cooking purposes such as natural gas , methane , propane , butane .
A gas non-return valve (NV), which: prevents dangerous gas mixtures. ensures the gas only flows in the intended direction. and a flame arrestor (FA), which: cools the flame to below the ignition temperature of the gas or gas mixture. prevents flashback. In addition to these two basic safety functions a flashback arrestor can also have a:
In fire and explosion prevention engineering, purging refers to the introduction of an inert (i.e. non-combustible) purge gas into a closed system (e.g. a container or a process vessel) to prevent the formation of an ignitable atmosphere. Purging relies on the principle that a combustible (or flammable) gas is able to undergo combustion ...
To help you avoid a gas leak and detect if one is happening, Craig Hoeferlin, Spire’s vice president of operations services and safety management systems, shared advice for staying safe around gas.
Safety cabinets to BS EN14470-2 for pressurized gas cylinders, are designed to accommodate cylinders in working areas. The gas is supplied to the desired application via a pipeline through pipe lead-throughs in the roof of the cabinet. These pipe penetrations must be sealed to ensure fire protection.
The Minnesota Department of Public Safety State Fire Marshal (SFM) determined that the 100-pound propane cylinder, which was believed to be empty, contained enough leftover gas to fill the storage ...

Oil tankers fill the empty space above the oil cargo with inert gas to prevent fire or explosion of hydrocarbon vapors. Oil vapors cannot burn in air with less than 11% oxygen content. The inert gas may be supplied by cooling and scrubbing the flue gas produced by the ship's boilers.
