Comparison of EPA’s RMP vs OSHA’s PSM at-a-glance

The elements and language of the risk management rule are, to the maximum extent possible, identical to the parallel elements in OSHA’s Process Safety Management (PSM) standard. One important difference between PSM and RMP is that, under the Clean Air Act (CAA) amendments, OSHA, must protect workers from chemical incidents at facilities that use highly toxic, reactive, flammable, or explosive substances. EPA must protect public health and the environment. This chart compares the two programs to help you understand where there are differences. Keep in mind that most facilities that fall under the scope of both PSM and RMP fall into RMP Program 3.
