Before an operator is permitted to work in a covered process, OSHA requires initial training covering the safety and health hazards of the process, emergency operations including shutdown, and safe work practices applicable to the employee's job tasks. These letters address the scope and content of initial training, the permissibility of on-the-job training components, when training must be completed relative to the employee beginning process work, and what documentation must accompany the training. Operators who transfer from one process unit to another require initial training for the new process even if they have worked in PSM-covered processes before.

What OSHA Has Said

May 28, 1993
Initial Training Content and Scope and Minimum Requirements
OSHA identifies the minimum content required for initial operator training: process-specific hazards, emergency shutdown procedures, and safe work practices for the operator's specific job tasks. Generic safety training does not satisfy this requirement.

On-the-Job Training as a Component of Initial Training
OSHA addresses whether OJT can satisfy part of the initial training requirement. OJT components are permissible but must be structured, documented, and assessed. Unstructured shadowing is not compliant initial training.

Initial Training for Transfer Employees and Cross-Process Requirements
OSHA confirms that operators transferring from one covered process to another require initial training for the new process. Prior experience in PSM-covered facilities does not satisfy the requirement for process-specific initial training.

⚡ Key Compliance Takeaway

Initial training is process-specific, not generic. An operator who moves from Unit A to Unit B needs initial training for Unit B even if both are covered by PSM. Structure your OJT component with checklists, document completion, and assess understanding before the operator works without direct supervision.
