Another great review on the design, construction, and capacity of flammable storage cabinets, a topic that seems never to go away. Safety Tip: Single-walled supply cabinets do not work….

At 1:30 p.m. on December 27, 2021, two employees worked in spray painting operations on a ship. At some point, the hose line was clogged with debris and paint material. The employees poured paint thinner into the hose to attempt to clear the clog. Employee #1 held the hose line while Employee #2 regulated the…...
Call me crazy, but this just blew me away. And once again we find ourselves faced with an “industry practice” vs. “RAGAGEP”. We were at a facility several years ago where pieces of equipment are painted and this painting is a huge pride of the manufacturing sector and hence they have some very tight QA…...
This is an EXCELLENT 1-page Alert on the hazards of “Splash filling” non-conductive flammable liquids. SPEED MATTERS, as does process design!

The report said an abnormal flow of electricity occurred as a result of “improperly grounded equipment” in the roof area of the tank, a static discharge or ignition charge in the tank was the “most probable cause of ignition” in the October 15, 2019 incident. The tank’s roof…...
This is a very high-tech and expensive VaneometerTM. I am kidding, it is only around $40 and it may be one of the simplest safety devices we will ever use. But don’t let the price or simplicity fool you – it is an ABSOLUTELY CRITICAL device for those of you that have ventilation systems, especially…...
Years ago, WorkSafe British Columbia (BC) put out a really nice video about a fatality caused by a worker welding on a used Acetone Drum. Although the video states the drum is a 44-gallon drum, it is in fact a 55-gallon drum. 44 imperial gallons is equal to 52 US gallons – which we call…...
The major hazard involved with transferring flammable liquids is static build-up due to charge separation with the potential for discharge resulting in fire and subsequent loss of containment. Certain non-polar liquids can be charged while flowing through piping. Detectable and hazardous charges must be expected if the specific resistance of the liquid exceeds 108 ohms…....
I studied this incident closely while at MSU and I have never forgotten the dramatic images of what 18,000 gallons of a flammable liquid can do in a sewer! On Feb. 13, 1981, at 5:16 a.m. a series of explosions occurred in the sewer lines of Louisville, KY. The explosions happened after a soybean extraction…...
Flash-fire incidents occurred during multiple types of operations, including maintenance on a control panel when natural gas was being vented, flammable fluids being drained into a bucket, or flammable liquids being transferred between containers. A static discharge can occur when an electrical charge accumulates on the surfaces of two materials, one with a positive charge…...
Enclosed processing areas (vs. outside and open processing areas) that are handling/using the following, shall be ventilated at a rate sufficient to maintain the concentration of flammable vapors within the area at or below 25% of their lower flammable limit (LFL). Class I flammable liquids or as OSHA calls them Category 1/2 flammable liquids, Class II…...
Liquid storage areas where dispensing is conducted must have either a gravity ventilation system or a continuous mechanical exhaust ventilation system. If the dispensing involves Class I liquids (e.g. Category 1 & 2 liquids per OSHA terminology) mechanical ventilation is the ONLY acceptable option. Regardless of the type used there are some FUNDAMENTAL requirements that…...
