A fine example of how the safety profession has drifted from science is the vast misunderstanding of hazardous gases. From their hazards to their behaviors, we have a lot of myths and misconceptions about hazardous gases. Sadly, the fact that OSHA does not have a “flammable gas” standard plays a role in this situation –…...

I mean, think about why did OSHA promulgate the LOTO standard – people were turning on machines with workers inside. But this case was exceptionally bad! A father found his son inside…...
In this month’s CT-OSHA Safety Newsletter, the agency is pushing the ANSI Z358.1–2014 standard as their baseline EW/SS enforcement standard. The entire newsletter, which you should sign-up for, is dedicated to EW/SS’s and is full of great info. I am not a lawyer, but I do not think they can enforce a consensus standard that…...

By adopting ANSI Z358.1-2014, Nevada OSHA has identified the minimum design and installation criteria necessary to meet the definition of suitable facilities, which is otherwise undefined in federal statute. Additionally, training requirements have been introduced…...
Employee #1 attempted to replace a leaking oil valve on a minus 30 degree freezer when a tank inside the freezer exploded. The company uses anhydrous ammonia to manufacture ice cream.
