If your team is focused on an event’s probability or likelihood, you’re NOT doing SIF! The Serious Injuries and Fatalities (SIF) model is intended to IDENTIFY events that have opportunities to cause life-altering injuries and death. And yes, most of these will (hopefully) have LOW frequencies/probabilities. So, to justify NOT responding to these LOW frequency…...

The purpose of barrier[/controls/safeguards] management is to make the kind of implicit controls explicit: to be clear about exactly what controls are relied on to prevent incidents, to understand their characteristics, to have an understanding of how reliable they can be expected to be, and to know what needs to be done to ensure the…...

Respondent produced, used, or stored more than 2,500 pounds of chlorine at the Facility and was subject to the requirements of CAA § 112(r)(7). Respondent produced, used, or stored hydrogen at the Facility and was subject to the requirements of CAA §…...
In terms of Fire and Building Codes, we have five (5) recognized areas associated with handling hazardous materials. We refer to these high-hazard areas/occupancies as “Group H”. High-hazard Group H occupancy includes, among others, the use of a building or structure, or a portion thereof, that involves the manufacturing, processing, generation or storage of materials…...

During a recent design review, we encountered some questionable “normal breathing” designs. I have always used the simplest of tests to ensure the tank has ADEQUATE venting during filling and emptying. Although OSHA allows the designer to use API 2000 (1968) or “other accepted standards,” the simplest test is that the VENTING capability MUST be…...

“We were doing some cleaning at the end of yesterday. I boiled some water in the HLT to pump through the heat exchanger. At the end of the day, there were 40-50 gal left in our 3bbl HLT. I turned off the heat and went home for the night. The next morning, I came into…...

An ISO container, partly filled with Monoethylene Glycol (MEG), imploded on the back deck of a ship, spilling around two cubic meters (528 gallons) of MEG onto the deck and to sea and causing unrepairable damage to the tank itself. There were no injuries. The tank was a 26-cubic-meter tank containing ten cubic meters (6600…...

OSHA has again found a large food manufacturer with a history of hazardous workplace safety practices in violation of dozens of safety and health hazards. The producer of glass-pack, canned, frozen, refrigerated, freeze-dried, and snack food products under it’s brand, as well as other private labels, also operates eight other manufacturing plants, including five in…...

One mistake many businesses make is their assumptions about how their flammable liquids will behave once they are outside of their primary containment. I have seen companies spend millions of dollars to classify an area as a HAZLOC when it was not even close to being necessary, and I have seen some PSM businesses claim…...

I will again reference my 30 years of teaching emergency response courses and the surprising lack of hazard awareness so many “certified technicians” lack. The one that get a lot of attention is the relationship between TOXIC and PHYSICAL hazards when the HAZMAT is both toxic and flammable. I have shared many tips over the…...

One of the top questions I get via SAFTENG and in my PRCS or Hazardous Atmospheres training courses is… Why did OSHA use 10% LEL to define a hazardous atmosphere? There is an official and logical reason, both of which should be understood. First, the “official” reason:… Membership Required You must be a member to...
