When determining whether a threshold amount of a regulated substance is present in a process (e.g., a tank), must the owner or operator of a stationary source consider the total capacity of the process, or the actual amount of regulated substance contained in the process?
How far apart do separate vessels have to be to be considered different processes?
I had a release where several people were treated at the hospital and released; they attributed their symptoms to exposure. We do not believe that their symptoms were in fact the result of exposure to the released substance. Do we have to report these as offsite impacts?
Facilities subject to the Program 3 Prevention Program requirements in 40 CFR Part 68 must include in their Risk Management Plan the date of the most recent review or revision of hot work permit procedures in Section 7.13. What is considered hot work and what are the requirements related to hot work?
I’ve noticed that for certain chemicals, RMP*Comp gives substantially different distances to the toxic endpoint than previous versions. Why?
The prevention program requirements under 40 CFR Part 68, Subparts C and D, include hazard reviews and process hazard analyses. Is a hazard review synonymous with a process hazard analysis (PHA)? No!
The Program 3 prevention program requirements under 40 CFR Part 68 are almost identical to the requirements of OSHA’s process safety management (PSM) standard. OSHA exempts certain industries from the PSM standard. Why does EPA not exempt those same industries from the CAA §112(r) risk management program requirements?
What if the quantity in the process fluctuates? I may not have a threshold quantity now, but I will intermittently exceed the threshold quantity.
The owner or operator of a stationary source covered by the risk management program regulations must conduct a worst-case release scenario analysis as part of the required hazard assessment (40 CFR §68.25). The worst-case release is defined as the release of the largest quantity of a regulated substance from a vessel or process line failure
For the purpose of analyzing the worst-case release scenario required as part of the hazard assessment at 40 CFR Part 68, Subpart B, the worst-case release quantity is identified as the greatest amount held in a single vessel or pipe, taking into account administrative controls that limit the maximum quantity (40 CFR §68.25(b)). Why did
Below is a video of a tragic accident that occurred today in Jordan’s Aqaba shipping port. A 25-Ton ISO Container of Chlorine (Cl2) (like the image to the left) was being lifted off a truck and onto a ship when somehow the container was dropped (too early to know the cause). The video shows the
This is one for all the Behavior-Based Safety Observation admirers who somehow convinced themselves their BBS process is flawless. Most of us in the safety profession has seen the “gorilla and basketball” video. The study used a video made famous by earlier “inattention blindness” research featured in the 2010 book “The Invisible Gorilla,” by Christopher
