A new version of MARPLOT is available (4.2.4)
What’s changed in MARPLOT 4.2.4? Recently, the Get Address feature broke in all MARPLOT 4.x versions, because the Google web service that MARPLOT was using was discontinued. The MARPLOT 4.2.4 release fixes the Get Address feature, which now uses a newer version of Google’s Reverse Geocoding tool to find the address at a click point…....
OSHRC rules on “off-site” PRCS Rescue Services
This is an interesting citation, one that to me appears OSHA was not happy with this employer. As I read this decision, I was shocked that OSHA would have issued a citation, much less a Serious, in this situation. If all employers did 1/4 of what Cargill does at this facility for PRCS entry then…...
What could your NH3 38,000 pound WCS look like?
Many have never seen a large and sudden release of anhydrous ammonia (NH3). Most who work with Ammonia have seen the Seward, IL ammonia release videos; however, these two videos do not put the release into perspective as to the large area which is impacted by these catastrophic releases. The Texas Air Control Board took…...
PHA’s and “previous incidents”
One area that is often overlooked or not applied during process hazards analysis (PHA) is a review of previous incidents. This is often not done as the process has no reported incidents in the past five years. We can discuss/challenge that “phenomenon” in a later posting, but I wanted to offer this bit of advice……...
Pressure Vessel Accident Rates
With the release of the CSB accident report involving the catastrophic failure of an ASME pressure vessel and me posting it this afternoon, I am already getting e-mails (5 and counting within the first two hours) claiming the incident is “1 in a million” and that I am scaring people for no sound reason. Really?…...
CATASTROPHIC FAILURE of ASME Pressure Vessel (Video and CSB Investigation)
This accident occurred December 7, 2009, with a violent rupture of an ASME pressure vessel. The video contains an animation which depicts the stress corrosion cracking (SCC) that accumulated over time in the walls of a pressure vessel where synthetic quartz crystals were manufactured under extremely high pressures and temperatures. The incident had many failures…...

OSHA is considering revising its Process Safety Management (PSM) standard
OSHA is considering revising its Process Safety Management (PSM) standard, 29 CFR 1910.119, to address gaps in safety coverage; or updating its Flammable Liquids standard, 29 CFR 1910.106, and Spray Finishing standard, 29 CFR 1910.107, based on the latest consensus standards. The following options are being considered:… Membership Required You must be a member to...
