This is the first and only PSM citation that I have seen from IN-OSHA. It is a single violation cited for contractor safety, and it appears it may have been related to an incident involving a contractor working on an Ammonium hydroxide tank. I am NOT certain about this, just trying to read between the lines in the citations.
However, as rare the IN-OSHA PSM citation is, the one that really caught my eye was the citation that the company, which is the manufacturer of the Ammonium Hydroxide, “did not identify the vapors released from this liquid as being flammable and the upper/lower flammability range for this vapor was not provided on the SDS“.
FINALLY, a manufacturer is being held accountable for a poorly written Safety Data Sheet (SDS). I have written several articles over the past few years, expressing my frustration with the poor quality of many SDSs. I have even explicitly written about flammable liquid SDSs, not providing the LEL/UEL range. So it is refreshing to see OSHA, albeit a state-run plan, taking issue with the quality of an SDS.
Here are the citations:
