The owner or operator must develop and implement written operating procedures consistent with the process safety information covering each operating phase (initial start-up, normal operations, temporary operations, emergency shutdown with the conditions requiring it and assignment of shutdown responsibility to qualified operators, emergency operations, normal shutdown, start-up after a turnaround or emergency shutdown), operating limits (consequences of deviation and steps to correct or avoid it), safety and health considerations (chemical properties and hazards, precautions against exposure including engineering and administrative controls and PPE, measures after contact or airborne exposure, raw material quality control and inventory control, special hazards), and safety systems and their functions, including documentation when release monitoring equipment is removed for imminent natural hazards. Procedures must be readily accessible to employees who work in or maintain the process, reviewed as often as necessary to reflect current practice, and certified annually as current and accurate. Safe work practices must control hazards such as lockout/tagout, confined space entry, opening process equipment or piping, and entry into the source by maintenance, contractor, laboratory or support personnel, for employees and contractors.
