I am proud to announce that SAFTENG and The Chlorine Institute have renewed our partnership for another year (through 2026). Members of The Chlorine Institute receive a FREE SAFTENG membership. If you qualify, please contact me
NOTE: Any trade group interested in becoming a partner with SAFTENG for your Member Companies, please reach out, and I can share the plan
SAFTENG has:
- Over 19,000 categorized unsafe acts/conditions and accident/injury photos
- Over 1,500 ppt's & doc's in the SAFTENG Library
- Over 5,000 Technical Articles on Process Safety, Emergency Response & OSH topics
- Over 450 videos (those not allowed on YouTube Channel)
Many THANKS to my NEW Members and those who CONTINUE to support SAFTENG:
A 43-year-old assemblyman died on May 26, 1999, from chest injuries he received earlier that day when struck by a high-pressure water jet emitted after the failure of a gasket during a hydrostatic test of a cooling coil for an air-cooled heat exchanger. At the time of the incident, the victim was part of a two-man team conducting hydrostatic testing at a heat exchanger manufacturing company. The laborer...

The rule—”Add Acid to Water” (AA)—is one of the most important safety practices in a chemistry lab. It all comes down to how much energy is released when they mix and how the liquid behaves as a result.
Let’s explore the science behind this safety rule together. I’ll ask guiding questions along the way.

Employee #1 entered a semi-trailer truck to wash out the inside, which had contained a fatty acid (linseed oil). A short time later, he was found lying at the bottom under the hatch opening. Employees #2 and #3 jumped in to rescue him and were nearly overcome.
Employee #1 died, and blood tests conducted two hours after exposure revealed carboxyhemoglobin levels of 56 percent for Employee #1, and...

The frequency for testing or replacing hydrostatic relief valves (HRVs) depends largely on the service environment, the fluid being handled, and the specific regulatory standards like OSHA, NFPA, CGA, or ASME governing your process. Because these valves are designed to protect against thermal expansion in liquid-filled lines—often in “blocked-in” sections—their reliability is critical...

A process, in terms of Process Safety Management, is defined as:
“Any activity involving a regulated substance including any use, storage, manufacturing, handling or on-site movement of such substances, or any combination of these activities. For the purposes of this definition, any group of vessels that are interconnected, or separate vessels that are located such that a regulated...

One of the debates we routinely have with fellow process safety professionals is the adoption of NFPA 51B vs. meeting 1910.252(a) requirements for their Hot Work safe work practice. I am a huge fan of NFPA 51B, as it is much more up-to-date than OSHA’s 1910.252, which, by the way, was based on the first edition of NFPA 51B in 1962. As I have stated many times before, PSM (nor RMP) does NOT allow...

A massive leak of liquefied chlorine gas created a dangerous cloud of poison gas over the city of Henderson, Nevada, in the early morning hours of May 6, 1991. Over 200 persons were examined at a local hospital for respiratory distress caused by inhalation of the chlorine, and approximately 30 were admitted for treatment. Some 700 persons were taken to shelters. It is estimated that from 2,000 to 7,000...

If we are making a final “tie-in” weld between two segments of pipe that have already been independently pressure tested, that specific weld can be exempt from a final system pressure test if:

Those of us living within the realm of Process Safety Management know all too well the difficulty of controlling contractor work activities to a level that we are confident they are not increasing our process risks beyond our acceptable levels. Many contractors are offended by the fact that many PSM programs have multiple layers of protection regarding their presence and work practices in, on, or even...

Behavior-Based observation and feedback processes promote desired behaviors by introducing POSITIVE REINFORCEMENT for behaving safely. The positive reinforcement is provided through POSITIVE FEEDBACK. These programs are based on the ABC behavior model, as I explain below. The effectiveness of behavioral safety observation and feedback programs is dependent upon effective implementation.
