The Group defines the type of hazardous material in the surrounding atmosphere. Groups A, B, C, and D are for gases (Class I only) while groups E, F, and G are for dust and flyings (Class II or III).Continue Reading

By looking at the HAC drawing where the area classification records can comprise detailed drawings with notes and/or can be in the form of tabulations. The area classification drawings should indicate sufficient scale to show all the main items of equipment and all the buildings in both plan and elevation.Continue Reading

Zone 1—Ignitable concentrations of flammable gases or vapours which are likely to occur under normal operating conditions. Zone 2: That part of a hazardous area in which a flammable atmosphere is not likely to occur in normal operation and if it occurs, will exist only for a short period.Continue Reading

Class II—Locations in which combustible dust (either in suspension, intermittently, or periodically) may or may not be insufficient quantities to produce explosive or ignitable mixtures. Class III—Locations in which ignitable fibres may or may not be insufficient quantities to produce explosive or ignitable mixtures.Continue Reading

Class I—Locations in which flammable gases or vapors may or may not be insufficient quantities to produce explosive or ignitable mixtures. Group D—Atmospheres containing a flammable gas, flammable liquid-produced vapour, or combustible liquid-produced vapour whose MESG is greater than 0.75 mm or MIC ration is greater than 0.80. Typical gases include acetone, ammonia, benzene, butane,...Continue Reading

Zone 2: That part of a hazardous area in which a flammable atmosphere is not likely to occur in normal operation and if it occurs, will exist only for a short period.Continue Reading

A loss control activity focuses on reducing the severity of losses. Examples include building firewalls to reduce the spread of fire and installing automatic fire sprinklers.Continue Reading

Any hazards that can lead to fires, explosions and toxic releases resulting in fatalities/ injuries, major asset loss and impact to the environment.Continue Reading

An engineer who involves in all activities intended to help organizations in any industry to prevent the loss, whether it be through injury, fire, explosion, toxic release, natural disaster, terrorism or other security threats.Continue Reading
