The investigation is NOT complete, but we can clearly see Hot Work was taking place within 10′ of the origin of this fire. In the video below, we can see the welders were actually using wooden pallets as work platforms, and the large pile of mattress foam was a mere ~10′ away. We can not…...
So I asked Google Gemini… What are the LEL correction factors for the top 5 direct reading instruments? I asked this as I wanted a side-by-side comparison of the DIFFERENT correction factors for these five (5) different meters. Some of the variation is 100% greater, so the moral of the story is that when you…...

There are very few instances where OSHA uses such clear language, but in 1910.252(a) they use the phrase “absolutely certain” and for good reason! This explosion occurred at a wastewater treatment plant in the city of Gumi, South Korea, on October 19, 2016. 1910.252(a)(3)(i) Used containers.No welding, cutting, or other hot work shall be performed…...
Or maybe you will. Got this from a friend today and its amazing footage of what a worker will do, either on their own accord or instructed to it, to get a job done. Members can view the video below and download it from the Video Library (Unsafe Acts Category)…. Membership Required You must be...
I have had a numerous discussions with companies regarding this new push for “trans-loading”. Trans-loading is defined as: “Transloading means the transfer of a hazardous material by any person from one bulk packaging to another bulk packaging, from a bulk packaging to a non-bulk packaging, or from a non-bulk packaging to a bulk packaging for…...
Low humidity makes most LEL (Lower Explosive Limit) detectors read lower than they should, because catalytic‑bead sensors depend on moisture for heat transfer and baseline stability. This can lead to under‑reporting of gas concentration, slower response, and—in extreme dryness—temporary sensor desensitization. Below is a clear, technically grounded explanation based on how LEL sensors work and…...
“Wolf Syndrome” in the context of false alarms refers to a pattern where repeated false alerts cause people to stop responding, even when a real danger appears. It’s based on the classic “crying wolf” concept and is widely discussed in psychology, emergency management, and safety‑system design. The term is not a medical diagnosis—it’s a metaphorical…...
The dome failed at a repair patch that had been improperly welded and did not provide the minimum thickness needed to contain the dome’s operating pressure. The steel mill’s mechanical integrity program lacked effective inspection and weld repair practices, contributing to the incident. In iron manufacturing, a blast furnace operates at high temperatures to convert…...
Updates to align with the UN’s GHS Revision 7 begin taking effect this month. Manufacturers and importers must have updated labels and Safety Data Sheets (SDS) for chemical substances. Employers have until July 2026 to ensure their onsite programs and training reflect these revised classifications…. Membership Required You must be a member to access this...
In March 2026, NIOSH issued a formal request for information to update the IDLH Value Profiles. While ammonia has an established IDLH of 300 ppm, the agency is seeking new toxicology and human health effects data to refine these values. The Focus: The RFI specifically looks for “weight-of-evidence” data on how chemical modes of action—such…...
I stumbled across this international study regarding community effects from a large scale NH3 release in 2022. The study wanted to validate or in-validate community complaints years after the event. Residents, numbers unknown, had been complaining of “loss of smell” after being exposed to hundreds of ppm’s of NH3. The study was interesting in that…...
