Operating Procedures

Written procedures covering normal / startup / shutdown / emergency, certified annually

Strategic context

What this element is — and why it matters

OSHA PSM 1910.119(f) requires written operating procedures that provide clear instructions for safely conducting activities involved in each covered process. The element prescribes scope (f)(1) — initial startup, normal operations, temporary operations, emergency shutdown, emergency operations, normal shutdown, startup following turnaround — plus (f)(2) operating limits and (f)(3) safety/health considerations. (f)(3) requires annual certification that procedures are current and accurate.

Individual significance for organisations

Operating procedures are the daily language of the plant. Sites with current, validated, accessible procedures execute operations with consistency and resilience against turnover. Sites where operators work from notebooks accumulate procedural drift that eventually produces incidents. CSB findings repeatedly cite stale or inaccessible procedures as contributing causes.

Contribution to OSHA Process Safety Management (29 CFR 1910.119)

(f) operationalises (d) PSI and (e) PHA outputs into actionable instructions for the workforce. It directly enables (g) training execution, supports (i) PSSR readiness, and is updated by (l) MOC. The annual (f)(3) certification is one of the few elements with hard annual gates — a forcing function that keeps the rest of the system aligned with operational reality.

Key requirements

What compliant execution looks like

Written procedures per (f)(1) — startup / normal / temp / emergency / shutdown

Operating limits per (f)(2) with consequence of deviation

Safety and health considerations per (f)(3)

Annual accuracy certification per (f)(3)

MOC discipline triggering procedure update

Workstation accessibility with operator validation

Implementation methodology

How we implement this element

A focused 6-step methodology calibrated to deliver operating procedures as a working capability — not a documented compliance artefact.

Procedure Scope Audit

Per (f)(1) inventory required procedures — startup, normal, temp, emergency, shutdown; identify gaps and stale documents.

Operating Limits Documentation

Per (f)(2), document operating limits, consequence of deviation, steps to avoid or correct; align with PHA / IOW.

Safety & Health Considerations

Per (f)(3), include properties / hazards of chemicals, precautions, control measures, PPE, special / unique hazards.

Annual Accuracy Certification

Per (f)(3), annual procedure walk-down with operator signoff; MOC backlog reconciliation; documented certification.

Operator Validation & Delivery

Validate procedures with operator review; deliver via DCS HMI / tablet / paper at workstation; embed safety-critical warnings.

Compliance Verification

Monitor procedure adherence through observation; trigger refresh on systematic deviation; integrate with operator training.

Start

PSM owner initiates operating procedures programme

Required-Scope Inventory per (f)(1)

Startup / normal / temp / emergency / shutdown

Operating Limits Documentation

Per (f)(2) with consequence of deviation

Safety / Health Considerations

Per (f)(3) — chemicals, PPE, control measures

Operator Validation Walk-Through

Field validation; capture practical corrections

Decision

Pass Operator Signoff?

Decision gate

Issue + Workstation Delivery

DCS HMI / tablet / paper with safety-critical warnings

Annual Accuracy Certification

Per (f)(3) — walk-down + signoff + MOC reconciliation

MOC Trigger Integration

Procedure update enforced on each change

Deliverables

What we produce

Procedure inventory and gap register
Operating limits per (f)(2)
Annual accuracy certification protocol
Operator validation signoff
Workstation delivery system
MOC update procedure

Common pitfalls

Where execution fails

Procedures describing idealised process that doesn't match plant
Annual certification done as paper exercise
Operating limits without consequence-of-deviation guidance
Workstation accessibility blocked by DCS / tablet permissions
