Chemical Process Safety (PSM/RMP)

Occasionally, we see some pipe labeling requirements that exceed those found in ASME A13.1.  NFPA 2, 2023 has a few: (emphasis by me)

It is good that we are finding fewer and fewer facilities without pressure testing and leak testing records on their process piping.  But now comes the difficult question: Is pressure and leak testing required after maintenance or alterations on piping systems? So, most companies will have their newly installed piping pressure tested and leak tested

Ammonia is held for sale by a retailer in a large storage tank.  The retailer sells ammonia as an agricultural fertilizer and a coolant for air conditioning systems.   Section 311(e)(5) of EPCRA exempts from the definition of a hazardous chemical “(a)ny substance to the extent it is used in routine agricultural operations or is

The Department of Homeland Security’s Chemical Facility Anti-Terrorism Standards (CFATS) impose comprehensive federal security regulations for high-risk chemical facilities. Do the CFATS alter the requirements that apply to a facility covered under both CFATS and either the Emergency Planning and Community Right-to-Know Act (EPCRA) or the Clean Air Act §112(r) (i.e., the Risk Management Program

The current list of delegated states and counties is: NOTE: Kentucky, Puerto Rico, and the Virgin Islands no longer implement the program, and the regional office has taken over the implementation of those areas.

During a recent design review, we encountered some questionable “normal breathing” designs. I have always used the simplest of tests to ensure the tank has ADEQUATE venting during filling and emptying. Although OSHA allows the designer to use API 2000 (1968) or “other accepted standards,” the simplest test is that the VENTING capability MUST be

The following incident is a precautionary example of the potential hazards of improperly depressurizing piping to remove a hydrate.  During production operations, a control room operator observed a decrease in gas lift pressure supplied through a pipeline to a remote well location. The control room operator notified the onboard platform operators of the pressure drop

The Emergency Planning and Community Right-to-Know Act (EPCRA) requires businesses that store and/or manufacture, process, or use certain chemicals to complete the Tier II (EPCRA 311 and 312) Report and/or the Toxics Release Inventory (EPCRA 313) Report, also called the Form R. Section 112(r) of the Clean Air Act focuses on risk management for accident
