We Are Experts in PSM For Ammonia Refrigeration

OSHA Regulation 29 (CFR) 1910.119 requires that industrial refrigeration facilities with 10,000+ pounds of Anhydrous Ammonia on site must have a Process Safety Management (PSM) program in place.

The development, implementation, and on-going maintenance of a PSM program is not only required for governmental compliance but is critical for employee safety, protection of the environment, and to reduce costly downtime.

At Preston, we have safely designed, installed, and maintained industrial ammonia refrigeration facilities for over 75 years.  Since the first PSM requirements were enactment in 1992, we have applied our experience and knowledge to help hundreds of clients develop plans that are functional and responsible.
