Anytime I read of workers killed in explosions for which no cause is known, I try to read between the lines. This plant made carbon and graphite or used them.  They are both excellent conductors and frequently become airborne to settle in electrical parts.  Usually these materials are not combustible themselves but they can lead [...]

Often ComDust and electrical issues are linked. Usually these are preventable by housekeeping but improper electrical wiring are often a culprit. See the story in the local news. Another local story on the same blast.

In this excellent article interviewing Scott Margolin Imperial Sugar tells of their plan to use “FR” uniforms. They chose excellent uniforms by the way, BUT the photo on the cover has the female worker in a melting hairnet. Sad this one still hasn’t got out. The guys in the famous Cudahay Arc Flash Video were [...]

It still amazes me when governmental agencies miss key recommendations in accident investigations. The CSB didn’t even mention flame resistant clothing in the Imperial Sugar combustible dust explosion when it could have clearly made a difference. The Chemical Safety Board’s recommendations rightly place the main focus on housekeeping and other recommendations but they fail as [...]
