Web1) MESG (Maximum Experimental Safe Gap) - The maximum clearance between two parallel metal surfaces that has been found under specified test conditions to prevent an explosion in a test chamber from being propagated to a secondary chamber containing the same gas or vapor at the same concentration. 2) MIC (Minimum Igniting Current) Ratio - … Webof hazardous mixture that intruded into the explosion-proof wiring, the wiring containment can “contain” the resulting explosion. Then, any escaping hot gasses will be cooled sufficiently so that they would be incapable of igniting any of the hazardous mixture outside of the explosion-proof conduit or fixtures. 1.1 The fire triangle
WebA Class I Division 2 Location (C1D2) is a zone “in which volatile flammable liquids or flammable gases are handled, processed, or used, but in which the hazardous liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such ... WebThe primary concept behind intrinsic safety is the restriction of available electrical and thermal energy in the system so that ignition of a hazardous atmosphere (explosive gas or dust) cannot occur. This is achieved by ensuring that only low voltages and currents enter the hazardous area, and that no significant energy storage is possible.
