Our Story

How we became an industry leader.

APSM started in the early 1990’s as a consulting firm assisting companies with the OSHA PSM and EPA RMP regulations. Originally we focused on the consulting and service side of PSM such as PHAs, audits, RMP submissions, offsite consequence analyses, and the development of hard copy documentation and training records to facilities across the country.

After a few years of experience, we needed a better way to communicate with our clients and oversee the various elements, updates, and dynamic information needed to manage a successful compliance program. So, we developed a custom PSM/RMP management software tool to better facilitate communications between ourselves and our clients, with the end goal of a more complete management system.

Since these humble beginnings, APSM software is now used by over 350 companies, over 1,000 plant locations, and over 18,000 individual users. It is also used by global leaders in food service, food production, logistics, and many other industries.
