In discussion: Coal Mill Safety. At best, coal mill safety is not well understood and, at worst, it is ignored. When it comes to coal mill systems, most cement plant operators just presume that the supplier of the equipment knows all of the standards and rules and is capable of making a system that conforms to these and is therefore safe.

 — ASTM E1226 – Explosion Severity (Pmax and KSt): These parameters describe the maximum overpressure and volume-normalized rate of pressure rise that can be experienced during a deflagration or explosion involving a specific material. These values are used in the design of explosion protection systems.

Explosion Relief – Indoor Vessels. For indoor explosion relief systems, venting the duct to the outdoors is crucial to prevent hazardous gas and dust buildup. This, however, can have an impact on system design, as flame ejection may be more intense, requiring a larger vent area or a stronger vessel.

Washington, D.C., April 24, 2018: Today the U.S. Chemical Safety Board (CSB) released its final investigation report into the February 8, 2017, explosion at the Packaging Corporation of America's (PCA's) DeRidder, Louisiana, pulp and paper mill. The incident killed three contract workers that were performing welding and grinding, referred to as "hot work," …

 — Dust explosions occur frequently in feed mills. A corn dust explosion in the Wayne Feeds at Waynesboro, the USA, on 25 May 1955, killed 3 and injured 13. The violence of the explosion caused extensive property damage. Another severe explosion occurred in Kansas City, the USA, in 1958, when the Murray elevator was badly damaged.

Combustible dust explosion risk is one of the most challenging issues fire safety professionals face today. On January 20, 2012 in Burns Lake, British Columbia, we were reminded why. Shortly after 8pm, there was a combustible dust explosion and subsequent fire at the British Columbian mill run by Babine Forest Products.

even an explosion hazard (if containment and dispersion are also present). Operators, plant management, and plant staff can avoid fire and explosion incidents by following equipment design best practices and anticipating what electrical safety risks may be present in a facility by performing the HAC assessment where necessary.
