In 2025, I have already challenged three times regarding the proper pressure testing of piping systems. I am unsure where we got off track with this rather simple requirement. First, let’s look at how ASME B31.3 defines “design pressure.”… Membership Required You must be a member to access this content.View Membership LevelsAlready a member? Log...

In December 2006, a journeyman pipefitter (P1) was struck in the chest by a pipe cap that he was removing from a pressurized pipe. Some leaks in an 8-inch waterline needed repair. To help find the leak locations, valves were closed off in the lines, creating sectionalized portions of the air-charged waterline. The waterline was…...

Gas cylinders holding 1.5 ft3 of gas are often filled to ~2,100 psig. At such high pressure, damaged or mishandled cylinders can fracture violently and release enormous amounts of energy, comparable to…… Membership Required You must be a member to access this content.View Membership LevelsAlready a member?

Despite their huge diversity, each organizational accident has at least three common features: hazards, failed defences, and losses (damage to people, assets and the environment). Of these, the most promising for effective prevention are the failed defences. Defences, barriers, safeguards, and controls exist at many levels of the system and take a large variety of…...

The NEP was set to expire on April 8, 2025. The extension allows OSHA to continue identifying and addressing heat-related injuries and illnesses in workplaces. The NEP enforcement initiative includes policies and procedures for implementing a National Emphasis Program (NEP) to ensure that employees in high-hazard industries are protected from heat-related hazards, both indoors and…...
Question: Would OSHA accept the documents generated by our software as a substitute for the OSHA Form 300 and Form 300A to meet the requirements of OSHA’s recordkeeping regulation at 29 CFR Part 1904? Response: If the forms generated by your company’s software meet the requirements for equivalent forms at 29 CFR 1904.29 and 1904.32,…...

I have seen a cost savings trend that is increasing risks in a big way. It may seem minor to those who do not understand risk, but using a pressure cylinder without it being inspected and tested at its prescribed frequency is a serious safety miss. Usually, these risks are controlled somewhat when the facility…...

So I posed the question to over 30,000 safety pros across my LinkedIn and Facebook groups and SAFTENG members, and as I suspected, there was a lively debate on this matter. I have received numerous requests to break down the evaluation like I have done for other “tricky” spaces that fall outside the traditional CS/PRCS…...

According to China’s Maritime Safety Administration (CMSA), the shipping container explosion aboard the box ship YM Mobility at Ningbo in 2024 was caused by thermal runaway in a cargo of organic peroxides. The container in question was a refrigerated shipping container filled with tert-butyl perbenzoate (TBPB), a common activator for making plastics like polyethylene and polyester. It…...
