Topic: Dust explosions pose serious and widespread hazards in process industries such as pharmaceuticals, foodstuffs, agriculture and aerospace. Events involving dust explosions can result in injuries or fatalities, plant shutdown, and sometimes destruction of the facility.
Dust Hazard Analysis (DHA) is an important element needed in any dust handling safety program. A DHA helps identify a basis of safety to prevent combustible dust fires and explosions. Additionally, some Authorities Having Jurisdiction expect a DHA to be performed in accordance to recently published National Fire Protection Association standards. NFPA 652, Standard on Fundamentals of Combustible Dust, requires a Dust Hazard Analysis (DHA) to be completed for in-scope facilities by September 7, 2020. NFPA 61, Standard on the Prevention of Fires and Dust Explosions in Agricultural and Food Processing Facilities, sets the DHA deadline for in-scope facilities for January 1, 2022.
This webinar will provide those conducting their first DHA with a better understanding of what is needed to cover the basics of a DHA from the explanation on dust combustibility characteristics (Kst, Minimum Explosible Concentration, Minimum Ignition Energy, Minimum Ignition Temperature) important to a DHA, processing equipment (dryers; dust collection systems; hammer mills and belt conveyors), and the appropriate methods of ensuring operator safety.
