Differences between a H-2 and H-3 occupancy
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
“Normal venting” for aboveground tanks
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
Condensing water vapor creates a vacuum, destroys tank
“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
Implosion of ISO container during transfer (Vent valve NOT opened)
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 PSM citations @ Food plant (NH3 & $394K)
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
When do I need to consider desinging and managing an area as a HAZLOC?
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
Just because you won’t be working in a flammable atmopshere, it may still be TOXIC
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
Why does OSHA use 10% LEL to define a HAZ ATM within a PRCS?
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:
“Banner Safety,” it can work, but often does more harm than good
We have all seen them; most of us have used them to deliver a safety message. Let me say this up-front: it is never the banner’s fault! A SAFTENG member was reading my posts about “safety banners” and contacted me to discuss their use. They were convinced I was 100% against using “safety banners” after
PRCS incident kills 7, injures 3 @ Cement Plant (LOTO Failure – 2 Videos)
Source: VnExpress/Anh Phu Seven (7) workers were killed, and three (3) others were injured while conducting periodic maintenance on one of the plant’s kilns when the incident occurred. When the workers entered the rotary kiln to start the repair work, the kiln unexpectedly restarted. Replacing the eroded kiln plates is done every 5-7
