Sources of such hazards include gases , vapors , dust , fibers, and flyings, which are combustible or flammable. Electrical equipment installed in such locations could provide an ignition source, due to electrical arcing , or high temperature. Standards and regulations exist to identify such locations, classify the hazards, and design equipment for safe use in such locations. A light switch may cause a small, harmless spark when switched on or off. In an ordinary household this is of no concern, but if a flammable atmosphere is present, the arc might start an explosion.

Our poster gives you quickest possible access to explosion protection knowledge. For gas and dust explosion hazardous areas, it explains the respective zone and division classifications as well as legal and technical product markings and protection principles.

To minimize these risks, a sound understanding of the chemical substances in use and their safety-relevant attributes is essential. This brochure explains the fundamental principles of explosions. This brochure addresses users who design and develop intrinsically safe circuits.

The brochure outlines the most important requirements for a simple apparatus in addition to other relevant information. Combustible dusts are materials that can smolder or burn as heat builds up in the presence of oxygen e. If a dust layer is ignited, a combustion will occur. A dust combustion can develop into a dust explosion.

Beta This is a new way of showing guidance - your feedback will help us improve it. This Technical Measures Document refers to the classification of plant into hazardous areas, and the systematic identification and control of ignition sources. The relevant Level 2 Criteria are 5. The Dangerous Substances and Explosive Atmospheres Regulations DSEAR provide for the first time a specific legal requirement to carry out a hazardous area study, and document the conclusions, in the form of zones. Area classification may be carried out by direct analogy with typical installations described in established codes, or by more quantitative methods that require a more detailed knowledge of the plant. The starting point is to identify sources of release of flammable gas or vapour.

James A. Huddleston, P. E lectrical and electronic equipment such as motors, generators, transformers, circuit breakers, fuses, switches, relays, solenoids and resistors produce significant amounts of heat, arcing and sparking during normal and abnormal operation, which could pose a substantial risk of fire or explosion in facilities where chemicals are manufactured, processed or utilized. This holds especially true for hazardous classified locations, i. H azardous area classification is the evaluation and classification of hazardous classified locations using scientific and engineering principles, within facilities where chemicals are manufactured, processed or utilized.
