Certification & Approval   •  Certified by Central Mining Research Institute (CMRI), Dhanbad, Zharkhand for Gas Gr-I, IIA & IIB. • Approved by • Director General of Mines Safety (DGMS), Dhanbad, Zharkhand. • Chief Controllerate of Explosive (CCE), Nagpur. • Directorate General of Factory Advise Services and Labour Institute(DGFAS & LI), Bombay     Flameproof Environment   An Explosive atmosphere is one where mixture with air under atmospheric conditions of flammable substances in the form of gas, vapour or mist exist in such preparation that may explode due to excessive temperature, arc or sparks. Flameproof motors are manufactured with an enclosure constructed in such a manner that any explosion inside is not capable of lighting an explosive atmosphere outside the enclosure.   Zones   Hazardous areas have been classified into three zones as follows : Zone-0  in which an explosive air-gas mixture is continuously present or present for long periods. (N.B. - no. Motors may be used in Zone 0.). Zone 1  in which as explosive air-gas mixture is likely to occur in normal operation. Zone 2  in which as explosive air-gas mixture is not likely to occur in normal operation & if it occurs it will exist only for short time. By implication an area other than zone 0, 1 & 2 is deemed to be a non-hazardous or safe area. Temperature Considerations   Ignition Temperature The minimum temperature at which a gas, vapour, mist ignites spontaneously at atmospheric pressure is known as the Ignition Temperature. As the gases and vapour encountered in / industry have a wide spread of Ignition Temperatures, it has been agreed internationally to group together those which lie within certain temperature bond.
