OSHA states “pre-charged air conditioners and heat pumps” in a warehouse or distribution center are subject to 1910.119, if the aggregate weight of the refrigerant, a flammable gas,on the premises exceeds the threshold quantity (TQ) of 10,000 pounds

On May 6, 2021, the Environmental Protection Agency (EPA) published a Final Rule listing R‒452B, R‒454A, R‒454B, R‒454C, and R‒457A as acceptable substitutes, subject to use conditions, for use in residential and light commercial air conditioning and heat pumps. These refrigerants are flammable and are classified as belonging to ANSI/ASHRAE Standard 34 safety group A2L.

Electrical equipment certified by an organization that is NOT an OSHA Nationally Recognized Testing Laboratory (NRTL)

Does all fixed/portable/mobile equipment that is installed or enters a Hazardous Location (HAZLOC) have to be “certified” and “labeled” as being acceptable for that specific HAZLOC? The blunt answer is YES! But in today’s working world and global economy, I am seeing a lot of foreign approvals for electrical equipment that is not by one

Written Procedures for the QA of “Piping/Weld Examinations” (1910.119(j)(6)

Those of you who practice in the Process Safety arena are well aware of OSHA’s and EPA’s requirements to have “written procedures to maintain the on-going integrity of process equipment.” (1910.119(j)(2). However, OSHA and EPA also have a section in their Mechanical Integrity elements titled “Quality Assurance.”  1910.119(j)(6) Quality assurance. 1910.119(j)(6)(i) In the construction of

A single Pressure Relieving Device (PRD) protecting multiple Pressure Vessels

I see severe risk-taking regarding “safety assumptions” in process safety in my travels. I guess I am just “old school” and believe that every Pressure Vessel (PV) deserves its very own Pressure Relieving Device (PRD). But in today’s economy, where “costs” can be a driver in decision-making, I have experienced numerous scenarios where a single

EPA RMP citations @ bleach manufacturing plant (Cl2 & $88K)

The Respondent owns and operates a bleach manufacturing facility, which operates a bleach manufacturing process (the Process) and maintains a maximum chlorine inventory greater than the threshold quantity of 2,500 pounds. The Process is subject to OSHA’s process safety management standard, 29 C.F.R. § 1910.119, because the Process involves greater than the threshold quantity of

R-Stamp weld or ASME B31.3 weld?

For my Process Safety followers, here is your Monday Morning “trick question” (which I do not know the answer to)… Scenario: I have an ASME Section VIII Pressure Vessel that will be used in flammable liquid service. The “dip leg(s)” inside the vessel do not extend down to 6″ from the bottom of the vessel
