PSM vs. RMP: Understanding Two Important Ammonia Compliance Programs
PSM and RMP are two acronyms that come up frequently around industrial ammonia refrigeration. They are related, but they aren't interchangeable. Understanding where OSHA's Process Safety Management (PSM) and EPA's Risk Management Program (RMP) fit into your operation is an important first step toward managing compliance.
PSM is administered by OSHA and focuses heavily on preventing or minimizing catastrophic releases involving highly hazardous chemicals in the workplace. For covered ammonia refrigeration processes, the program includes interconnected elements such as Process Safety Information, Process Hazard Analysis, operating procedures, training, Mechanical Integrity and Management of Change.
RMP is administered by the EPA and addresses accidental chemical releases and risk management. Depending on a facility and its regulated processes, RMP requirements can overlap substantially with work already being done as part of PSM.
For facility managers, that overlap can become confusing. A refrigeration system isn't concerned about which acronym is printed at the top of a form. The equipment, employees, operating procedures, hazards and maintenance practices all exist together.
That's why good PSM assistance and RMP assistance should begin with understanding the actual ammonia refrigeration facility. What equipment is installed? Are the P&IDs accurate? Are operating procedures current? Is Mechanical Integrity being documented? Have changes to the system been properly managed?
This is also why engineering experience matters. Doubl-Kold's staff includes professional engineers and industrial refrigeration technicians specializing in areas such as anhydrous ammonia, controls, compressor rebuilds, startups and pumps. Our in-house engineering capabilities include PSM, system design and facility evaluations.
The goal shouldn't be to generate paperwork simply because paperwork is required. A good compliance program should support safer operations and give the people responsible for the facility useful information about their system.
EPA continues to provide specific compliance and safety resources for the ammonia refrigeration sector, making this an area facilities should continue paying attention to rather than assuming last year's program is automatically sufficient this year.
If you're trying to sort through PSM, RMP, ammonia refrigeration compliance, Mechanical Integrity or engineering requirements, you don't have to figure it out alone. Give Doubl-Kold a call and let our experienced team help you determine the right path for your facility.
