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:
Temporary Emergency Exposure Limits (TEELs) are guidelines designed to predict the response of members of the general public to different concentrations of a chemical during an emergency response incident.
Note: TEEL values are NO longer included specifically in ALOHA, see PACs.
TEELs estimate the concentrations at which most people will begin to experience health effects...

Emergency response personnel may have never heard the acronym AEGL, but that doesn’t mean it does not play a major role in the decision making process at almost all emergency responses to hazardous materials. AEGL’s and ERPG’s are the most widely used exposure guidelines in emergency responses to hazardous materials. In fact, did you know the DOT Emergency Response Guidebook...

The EPA’s Risk Management Plan (RMP) rule was the first time many EHS professionals had ever heard of Emergency Response Planning Guidelines (ERPGs). That was 1999, and still today 2007 there are many EHS professionals outside the PSM/RMP arena who still have not heard of ERPG’s. This article is an attempt to explain what they are and how they are used in emergency response...

I am sure this article will ruffle a few feathers, but honestly, I am surprised and disappointed by that. But I do a lot of work in flammable liquid processing, and this topic always comes up during audits, PHAs, and accident investigations. Some folks will swear that only grounding is “required.” They get this from OSHA’s 1910.106(e)(6)(ii) Grounding section. However, although...

In process safety, we deal with a lot of pressure vessels and even some boilers. It took me years to understand the differences between the U-1, P-2, and P-3 forms and all the requirements for the placement and management of these pressure-retaining containers. This article is intended to help safety pros who may have to deal with these types of pressure-retaining containers; so this is a 30,000-foot...

Below is OSHA’s official position on the need for hydrostatic relief valves in an Ammonia Refrigeration process. This is a bold move on OSHA’s part as the Ammonia Refrigeration industry and their trade groups have consistently stated that a “trained operator” is better than a hydrostatic RV.

I recently worked with a client on their emergency response efforts, and we continue to find businesses that do not understand the different requirements of qualifying a worker to use a respirator under CONTROLLED workplace exposures vs. UNCONTROLLED emergency response exposures. So, I wanted to write this article to make it as straightforward as possible…
Employee A is hired into a job...

When analyzing barriers, investigators should first consider how the hazard and target could come together and what was in place or was required to keep them apart. Obvious physical barriers are those placed directly on the hazard (e.g., a guard on a grinding wheel); those placed between a hazard and target (e.g., a railing on a second-story platform); or those located on the target (e.g., a welding...
