The Respondent owns and operates a bleach manufacturing facility, which operates a bleach manufacturing process (the Process) and maintains a maximum chlorine inventory greater than the threshold quantity of 2,500 pounds. The Process is subject to OSHA’s process safety management standard, 29 C.F.R. § 1910.119, because the Process involves greater than the threshold quantity of 1,500 pounds of...

For my Process Safety followers, here is your Monday Morning “trick question” (which I do not know the answer to)… Scenario: I have an ASME Section VIII Pressure Vessel that will be used in flammable liquid service. The “dip leg(s)” inside the vessel do not extend down to 6″ from the bottom of the vessel as required by all flammable liquid RAGAGEPs. The contractor...

So many want to accuse Heinrich of being too heavy on “unsafe acts” and claim that he held the workers too responsible for their injuries. This is just pure hogwash!

In this...

In the process safety arena, we have...

These days, too many companies have short-circuited their “new employee safety orientation.” They have either substantially shortened the time employees are in “safety orientation” or, worse, changed the format from face-to-face to a CBT format using information that is NOT even specific to the site-specific safety programs/practices. And then they call me and ask, “Why...

Most safety pros have seen the videos of workers in car washes doing some outlandish behaviors.  We may have been snickered at what we watched.  But this is the real result of what we saw in those videos… At midnight on January 13, 2024, an employee, 26, cleaned the car wash tunnel and equipment. The employee was cleaning the passenger side exit Top Mount Side Washer referred to as...

Please note, this is NOT a chemical process safety incident, but the design failures and human errors are directly related to process safety hazards. The design of a new passenger ferry’s engine and inadequate follow-on training for engineering crewmembers led to a 2022 fire aboard a Staten Island Ferry.  The fire broke out in the engine room of a passenger ferry in New York Harbor with 884 persons...
