August 10, 2020

SCS Project Director, Bill Lape, is an expert in the development and deployment of standardized Risk Management and Process Safety Management programs, including process safety program implementation and support to manufacturing facilities that utilize ammonia as a refrigerant.



That’s Bill Lape in a word.

and he’s a wonderful writer. Here are two of Bill’s most recent articles.


PSM SAFETY & COMPLIANCE CONSIDERATIONS IN THE AGE OF PANDEMICS  PSM safety programs and training remain a top priority during the pandemic. While online training is not a complete substitute for live, face-to-face PSM training and instruction, in the age of pandemics, it is a viable option. What to look for in PSM – ammonia refrigeration system safety training?

EPIC FAIL: ICE BUILD UP  When developing your inspections for your system’s mechanical integrity program, always be mindful of the potential consequences of ice buildup, particularly if it continues for an extended period of time.
