Companies that fall under Process Safety Management (PSM) requirements because of their highly hazardous chemicals are required to recertify that they have completed an evaluation of PSM compliance. Compliance evaluations must occur at least once every 3 years. Companies must certify that PSM compliance has been evaluated in order to verify that procedures and practices being followed are adequate and are being followed.
⚡ TL;DR: If your facility handles highly hazardous chemicals subject to OSHA PSM rules, you must conduct a compliance audit every 3 years and certify the results. This audit confirms your process safety procedures are adequate and being followed, and identifies corrective actions for any deficiencies found.
The audit needs to be planned ahead of time with plans for ensuring compliance, documenting findings, determining corrective actions and including field inspections of safety and health conditions and practices.
⚠️ What’s at stake: Failure to conduct required PSM audits exposes your facility to OSHA enforcement—serious violations carry penalties up to $16,550 per citation, and willful violations up to $165,514. More critically, uncorrected PSM deficiencies lead to process safety incidents: fires, explosions, toxic releases, worker injuries, and catastrophic environmental damage that can exceed millions in cleanup and liability costs.
The Team
Audit team members should be chosen based on their experience, knowledge, training and familiarization with the standard. Smaller companies may be able to have teams as small as one, but larger companies like refineries with 3 or 4 processes may need a team of 5-6 people over the course of 1-2 weeks. You can use your own personnel, personnel from other plants, or consultants to conduct the audit.
The Audit
The audit should: Make sure all PSM requirements are being followed; Identify elements that need special attention; Review pertinent documentation with samples large enough to ensure the audit results accurately reflect compliance; Inspect the physical facilities to observe actual practices; Interview all levels of plant personnel to determine awareness/knowledge of PSM requirements, safety procedures, and emergency procedures; and, Record any deficiencies.
Report of Findings
Following the audit, a report of findings should document the results, and that should be signed by a responsible manager. This becomes the official certification. If you use an outside consultant as the auditor, the employer still needs to make that certification, not the consultant. The report should include facts and information to support the audit did indeed determine and review compliance. It should document corrective actions required and document any findings so that they can be compared to future audits to determine trends. Additional observations discovered can also be included. Deficiencies should be described, given milestones, tracked and assigned to affected personnel, then periodically followed up on. Anything that was logged as a deficiency where no corrective action was taken needs to have explanations on why it wasn’t followed up on.
Is your facility’s PSM audit due or past-due? iSi’s process safety team helps chemical processing and manufacturing facilities conduct comprehensive PSM compliance audits, document findings, develop corrective action plans, and demonstrate ongoing compliance with OSHA standards. Get started →
Recordkeeping
Companies are required to keep their two most recent compliance reports on file. You do not need to turn those in to OSHA, just keep them on file and available for inspection.
Frequently Asked Questions
Q: What is the minimum frequency for PSM compliance audits?
A: PSM compliance audits must be conducted at least once every 3 years as required by 29 CFR 1910.119(m). Facilities must certify that PSM compliance has been evaluated to verify that procedures and practices are adequate and being followed according to OSHA standards.
Q: Who must sign the official PSM audit certification?
A: The audit report must be signed by a responsible manager at the facility being audited. Even if an outside consultant conducts the audit, the employer must make the official certification, not the consultant. This ensures management accountability for the audit findings and corrective actions.
Q: How long does a comprehensive PSM audit typically take?
A: The duration varies based on facility complexity. Smaller companies may complete audits in a few days with a small team, while larger operations with multiple processes (like refineries) may require 1-2 weeks with teams of 5-6 people to thoroughly evaluate all PSM elements and physical facilities.
Q: What must an audit include regarding deficiencies and corrective actions?
A: The audit must identify all deficiencies, assign responsible personnel, establish milestone dates for corrections, and include periodic follow-up documentation. Any logged deficiencies that were not corrected must include explanations. The audit report should compare findings to previous audits to identify trends and ensure accountability.
💰 The cost of non-compliance: OSHA serious violations for PSM non-compliance carry penalties up to $16,550 per citation; willful violations reach $165,514. Beyond fines, uncorrected PSM deficiencies directly increase the likelihood of process safety incidents—fires, explosions, chemical releases, and worker injuries that can result in casualty costs, third-party liability, regulatory escalation, and facility shutdown that exceed millions of dollars.
Every facility with PSM-regulated processes needs a compliant, current audit. iSi Environmental helps chemical processing and manufacturing facilities conduct thorough PSM compliance audits, identify and track corrective actions, and stay ahead of the three-year recertification requirement.
