Custom PLC Controls for Explosive Atmosphere
The National Electrical Code (NEC) defines hazardous locations as those areas "where fire or explosion hazards may exist due to flammable gases or vapors, flammable liquids, combustible dust, or ignitable fibers or flyings." The IEC has recently introduced the three-Zone system for combustible dust locations. In this project, Agape Water Solutions designed, built and programmed custom control ...

Combustible Dust: It Doesn’t Take Much
A dust accumulation of 1/32 of an inch deep—about the thickness of a dime—covering just five percent of a room’s surface area doesn’t sound like much, but it’s enough to cause a catastrophic explosion, according to the National Fire Protection Association (NFPA). Although good engineering and safety practices to prevent dust explosions have existed for decades, ...

What is Intrinsic safety and ATEX?
What is intrinsic safety? Intrinsic safety (IS) is a low energy signalling technique that ensures the safe operation of electrical equipment in hazardous areas by limiting the energy – both electrical and thermal – available for ignition. Why is this important? Explosive atmospheres can be caused by flammable gases, mists or vapours or by combustible dusts. Using intrinsically safe ...

Reducing the risk of dust explosion hazards
In the wake of recent tragic and highly publicized dust explosions, companies are asking, 'Could that happen here?' and 'What can I do to prevent such an incident at my facility?' One approach is to manage dust explosion hazards as though they were subject to OSHA’s Process Safety Management (PSM) requirements (29 CFR 1910.119), even though dust hazards often are not covered under this ...

Baghouse Dust Removal Options
As dust discharges into your dust collector’s hopper, ensuring you have the right removal method is going to help minimize problems that could arise due to dust build up. A hopper is designed to be temporary storage for your dust discharge. If you have excessive dust build-up in your hopper it can block off your dust collector air flow and cause a loss of suction throughout your dust ...
