Revision 16 of this pamphlet includes the addition of a section on fully-lined valves (4.1.9), a more robust section on liquid expansion chambers (5.5), recommendations on plastic pipe selections and discussion on gas permeability under vacuum (9), a caution on pneumatic testing (11.2.2), updated guidance on hydrostatic testing (appendix A, 2.3.1), and addition of a […]
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
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
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…
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?
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, 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:
The first (1st) public review of draft standard IIAR 4-201x, Installation of Closed-Circuit Ammonia Mechanical Refrigerating Systems is now open. Substantive changes resulting from this public review will also be provided for comment in a future public review if necessary. IIAR 4 specifies criteria for the installation of closed-circuit ammonia refrigeration systems. It presupposes that
Last week I wrote a posting about LOTO and got a lot of e-mails regarding the tone of my postings. To make my point, this week’s “photo of the week” is taken from an on-line training program for LOTO. Look very closely at this photo and post the OSHA violations you see. There are TWO
WARNING! This video may be upsetting to some; viewer discretion is advised. Firefighters said the 62-year-old man was hauling propane on a tow motor/forklift when a propane tank fell off of the vehicle onto the road. He then ran over the propane tank, causing it to explode, injuring the driver.
