The Process Safety Management (PSM) regulation requires host employers and contractors to work together to manage process safety. This course defines different types of contractors and reviews special safety requirements for employers at multi-employer work sites. Topics in this course include: Types of Employers, Host Employers, Contract Employers, Responsible Parties, and Working Together. After completing this course, learners will be able to identify the different types of employers on a multi-employer work site, recognize the responsibilities of host and contract employers, identify which party is responsible for safety, and identify how employers work together to protect their workers.
