Break-down of WA-OSHA (DOSH) NEW PSM standard for Refineries
This is a highlighted version of WA-OSHA’s DRAFT of their proposed PSM standard for refineries. I have highlighted those areas that are “new” as compared to OSHA’s PSM Standard (1910.119).
WA-OSHA has released its DRAFT language for its PSM Standard for Refineries
Last year we saw the state of California implement their “PSM for Refineries” standard and now the state of Washington’s Division of Occupational Safety and Health is releasing draft language for a new chapter that will ONLY apply to Process Safety Management (PSM) for petrochemical refining facilities. This Process Safety Management rulemaking is in the
Relief System Design Basis Tips from Canada’s TSSA
Here is some good ole sound advice on relief valves from our friends to the north (Technical Standards & Safety Authority). These are some good basic rules to follow, regardless of what country your pressure vessel operates.
When piping pressure tests go bad
Case #1 At 10:15 a.m. on February 12, 2015, an employee was working from the elevated basket of a manlift, installing sheetrock in an area of the job site where water piping was undergoing pneumatic testing, at 130 psi. At the same time, another contractor was performing a compressed air leak test. An 80-pound section
This is why using your hazardous material to perform the pressure or leak testing is NOT a good idea
On June 29, 2005, Employee #1 was involved in the following the maintenance activities in the Chloropyridines Complex at the employer’s chemical manufacturing facility. Employee #1 was returning a reactor vessel to service. He was attempting to do a pressure and leak test using chlorine gas. The pipe was supposed to be pressure tested with
One Entrant, Two “would-be rescuers” Fatal PRCS Incident (2017, H2S, Sewer Pipe)
It is 24 years after OSHA promulgated it’s Permit-Required Confined Space standard and then in 2015 OSHA promulgated their Confined Spaces in Construction standard and yet we continue to see more “would-be rescuers” dying in Permit-Required Confined Spaces as do actual “entrants”. We can only hope that one-day worker training and awareness will end the “would-be
2018 IFC changes the “leak detection” and “emergency shutoff” requirements for high hazard gases and liquids
I am not quite sure why they did this, but the ICC decided that the requirements for “leak detection” and “emergency shutoff” for high hazard gases and liquids ONLY apply when the “maximum allowable quantity per control” area is exceeded. This was done by moving these requirements from Section 5003 where they applied to any quantity
Evaluation of the Fire Hazard of ASHRAE Class A3 Refrigerants in Commercial Refrigeration Applications (NFPA)
Due to the potential environmental impact, there has been a shift to consider use of natural refrigerants, which have a lower Global Warming Potential (GWP) than traditional fluorocarbon based refrigerants. One type of natural refrigerant are hydrocarbons (e.g. propane), which are classified as Class A3 refrigerants per ASHRAE Standard 34. The Environmental Protection Agency (EPA) has a charge limit

Industrial CONFINED SPACE FATALITIES Two workers die while cleaning molasses tank in Queensland (two workers died while they were reportedly cleaning a molasses tank – the men, aged 52 and 48, died after being affected by fumes while cleaning the tank) LOTO FATALITY OSHA investigating fatal accident at Michael Foods (fatal incident happened at about
Opening the cage (LOPC) allows the animal to roam free
When we think about process safety, we can think of the analogy of a wild animal inside its cage… as long as the cage holds or we don’t open the door on the cage the wild animal is safely contained. Unfortunately, sometimes the cage was not designed to hold such a powerful animal and believe it
Disconnecting “process hoses” are by definition a “Line Break/Process Opening” task (Chlorine)
Most, unfortunately not all, process safety professionals will agree that doing a “line break” on an actual process pipe containing the PSM/RMP covered chemical (HHC/EHS) falls within 1910.119(f)(4) or 68.69(d). But when it comes to “process hoses”, there remain many application questions. For me, any time the “process” is opened I break the task down
