  5. Intrinsic safety - Wikipedia

    en.wikipedia.org/wiki/Intrinsic_safety

    Intrinsic safety (IS) is a protection technique for safe operation of electrical equipment in hazardous areas by limiting the energy, electrical and thermal, available for ignition. In signal and control circuits that can operate with low currents and voltages, the intrinsic safety approach simplifies circuits and reduces installation cost over ...

  7. Maximum experimental safe gap - Wikipedia

    en.wikipedia.org/wiki/Maximum_Experimental_Safe_Gap

    Maximum experimental safe gap (MESG) is a standardized measurement of how easily a gas flame will pass through a narrow gap bordered by heat-absorbing metal. MESG is used to classify flammable gases for the design and/or selection of electrical equipment in hazardous areas, and flame arrestor devices. [1]
