Vented gas cabinets are used by many trades and professions that commonly need to transport dangerous liquids or gases, such as fuel, oxy and acetylene. The vapors that can accumulate inside a cabinet holding a bottle of flammable liquids can build up and then accidentally be ignited by a spark from something small like a cigarette lighter. In order to avoid this dangerous situation, cans or bottles of chemicals and gases are usually stored in a vented gas cabinet.
The venting is designed to allow vapors to safely escape without causing an explosion. However, there are a few other remedies for this including a flame arrestor. This fine metallic screening is usually designed to prevent backflow or flashbacks of flames. It allows the vapors and harmful liquids and gases to pass through, while providing a blockade to flame passage should the vapors on either side catch fire.
Are Vented Gas Cabinets Mandatory by Law?
In most states, vented cabinets are not required by law. Some experts believe that cabinets holding flammable liquids or chemicals should not be vented. Though many local agencies do require venting, it mainly depends on the local fire codes (International Fire Code; the NFPA 1 Fire Code).
Are there Other Options to Venting?
Several other options do exist and may be used instead of vented gas cabinets. One of the most popular is an insert that contains activated carbon. This substance aids in lowering the levels of corrosive vapors or VOCs inside the cabinet.
Should the Cabinet Have Self-closing Doors?
Self-closing doors can be very helpful because workers are sometimes busy or preoccupied and might forget to close the door of a gas cabinet, exposing everyone to harmful fumes. Though they are not required by federal law, some local municipalities do require self-closing doors. Contact your local fire marshal or AHJ to learn whether your area requires this.
Other Helpful Tips
