Anhydrous Ammonia Safety Bulletin – Five Key Lessons to Prevent Hydraulic Shock (CSB)

The U.S. Chemical Safety Board released a safety bulletin intended to inform industries that utilize anhydrous ammonia in bulk refrigeration operations on how to avoid a hazard referred to as hydraulic shock.  The safety lessons were derived from an investigation into a 2010 anhydrous ammonia release. The accident occurred before 9:00 am on the morning

Does a facility have an obligation to notify DHS if the facility is closing?

Yes. A facility closure may be considered a material modification to a covered facility. In this case, the facility must complete and submit a revised Top-Screen to the Department of Homeland Security (DHS) within 60 days of the material modification (i.e., its closure), in accordance with 6 C.F.R. § 27.210(d), available at http://www.ecfr.gov/cgi-bin/retrieveECFR?gp=&SID=5490ca42ba3517c7c9aec9c47cefc750&r=PART&n=6y1.0.1.1.11.

PSM/RMP Refresher Training Frequency is not a 1,094 day vacation from training!

Yes, it is true… 1910.119(g)(2) states “Refresher training shall be provided at least every three years, and more often if necessary…” Please take note that the phrase “at least every” is used preceding the 3-year frequency, as well as OSHA explicitly states “more often if necessary”.  In my 20+ years of developing, implementing and managing

HHC/EHS UNLOADING reliance on Excess Flow Valves and another lesson on pipe erosion-corrosion

With the recent fatal accident involving methyl mercaptan, I thought it would be a good time to remind us of another significant methyl mercaptan accident that claimed the lives of three workers.  The recent accident claimed four workers via inhalation/asphyxiation and the one in 2001 involved ignition and the workers died as a result of
