A great article by Chris Giusto at Hallam-ICS What is a Dust Hazard Analysis (DHA)? April 9, 2019 In my last blog I discussed Combustible Dust Fundamentals and NFPA 652 and explained some of the background as to why NFPA 652 requires a Dust Hazard Analysis. Blogs posts within this series: Combustible Dust Fundamentals and NFPA 652 What is a Dust Hazard Analysis (DHA)? A Practical Guide to 5 Important Properties of Combustible Dust 7 Steps to Complete a Dust Hazard Analysis I've Completed My DHA, Now What? This blog will explain what a DHA is, and answer some other common questions about them. What is a DHA? A Dust Hazard Analysis (DHA) is a systematic review of the processes and areas of your facility where combustible particulate solids are present.  (Figure B.4.5 below from NFPA 652 shows how an example process is broken down into individ...

CTI EHS Blog: Conversion Technology engineers to wear FRC when conducting Combustible Dust Hazard Analysis From Brian Edwards Conversion Technology engineers to wear FRC when conducting Combustible Dust Hazard Analysis Flame resistant clothing (FRC) has been used for years in a number of industries to protect workers from flash fires, arc flash, embers, molten metal, and other potential sources of ignition to clothing.  The reason FRC is so important is that many fatalities have occurred because a worker's clothing has caught on fire, exposing him/her to burning heat for a much longer time than would have occurred during the initial event (e.g. arc flash, vapor flash fire). When looking at burn victims, there is a "magic" number - well, more accurately, a statistically relevant number - that predicts if the victim has a better chance of surviving ... or dying.  This number is 50%.  Meaning, when the percent ...
