Chemical Process Safety (PSM/RMP)

Process Safety Management Small Business Regulatory Enforcement Fairness Act (SBREFA) SER Background Document (May 2016)

The Process Safety Management (PSM) standard is intended to prevent or minimize the consequences of catastrophic releases of highly hazardous chemicals (HHCs). It requires employers to adopt a comprehensive management program that integrates technologies, procedures, and management practices to help assure safe and healthy workplaces. OSHA is considering revisions to the PSM standard, including changes

UPDATE on OSHA’s PSM Revisions (May 2016)

Pressure Differential Between Safety or Safety Relief Valve Setting and Pressure Vessel Operating Pressure (NBIC)

We have seen this far too often… operating ranges that are too close to RV set points.  Here is some excellent guidance from a great pressure vessel RAGAGEP, the National Board (NBIC-Parts 1-3) on how to establish the DESIGN characteristics for a pressure vessel based on the OPERATING PARAMETERS the vessel will be operating in…

How strong is your MI “Quality Assurance Program”?

Both OSHA and EPA require PSM/RMP facilities, more specifically covered process(s), have a QA program in their Mechanical Integrity (MI) Program… 1910.119(j)(6) Quality assurance. 1910.119(j)(6)(i) In the construction of new plants and equipment, the employer shall assure that equipment as it is fabricated is suitable for the process application for which they will be used. 1910.119(j)(6)(ii) Appropriate checks

Intrinsically SAFE instrumentation MATTERS (digital pressure gauge caused explosion that severed arm)

UPDATE 10/18/2016 – Hawaii Occupational Safety and Health Office reduced the number of violations cited from 15 to nine and lowering fines from $115,500 to $69,300.  About a month after the blast, the Honolulu Fire Department said its investigation determined the explosion was likely caused by a digital pressure gauge in the tank that produced an

What does 527 CMR 33.00: Hazardous Material Process or Processing have to do with the Boston NH3 Fatality?

On March 23rd a worker at a seafood processing building/warehouse in Boston, MA was killed in a catastrophic release of anhydrous ammonia. Since then there has been much speculation as to how this tragedy occurred and whether or not the facility’s refrigeration process fell under OSHA’s PSM and EPA’s RMP standards. As it appears at
