Strategic context

What this element is — and why it matters

OSHA PSM 1910.119(h) covers maintenance, repair, turnaround, major renovation, and specialty work performed by contractors on or near covered processes. The element splits responsibility — (h)(2) employer obligations (selection per safety performance, hazard information, pre-job orientation, injury tracking, periodic evaluation) and (h)(3) contractor obligations (employee training, supervisor responsibility, hazard reporting, safety-rule adherence).

Individual significance for organisations

Contractor incident rates historically run 2-5× direct-employee rates without a structured programme. Modern process industry depends on contractors for 30-60% of turnaround work hours. Organisations that manage contractors as peers see contractor incident rates that match direct-employee rates; those that treat contractors as separate carry disproportionate incident exposure.

Contribution to OSHA Process Safety Management (29 CFR 1910.119)

(h) extends the management system to the non-direct workforce executing the highest-risk activities — turnarounds, modifications, specialty maintenance. It integrates with (c) employee participation (joint H&S committees), (g) training (contractor competency), (k) hot work (PTW discipline), and (i) PSSR (contractor work close-out). Element (h) prevents the management-system coverage gap during the work where prevention matters most.

Key requirements

What compliant execution looks like

Contractor selection per safety performance per (h)(2)(i)

Hazard information communication per (h)(2)(ii)

Pre-job site orientation per (h)(2)(iii)

Injury / illness tracking per (h)(2)(iv)

Periodic evaluation per (h)(2)(v)

Contractor employer obligations per (h)(3)

Implementation methodology

How we implement this element

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

Selection Criteria

Per (h)(2)(i), build pre-qualification criteria — TRIR / LTIFR threshold, OSHA citation history, insurance certificate; align with ISNetworld / Avetta / OISD-149.

Hazard Information & Orientation

Per (h)(2)(ii) and (iii), pre-mobilisation orientation covering site hazards, evacuation, PTW system, emergency response.

Injury / Illness Tracking

Per (h)(2)(iv), specify reporting requirements — TRIR / LTIFR / OSHA recordable / near-miss with monthly aggregation.

Periodic Evaluation

Per (h)(2)(v), evaluate contractor safety performance during and after engagement; document for selection decisions.

Active Supervision

Tier-appropriate supervision intensity — continuous (Tier 1 high-hazard), intermittent (Tier 2), periodic (Tier 3).

Closeout & Re-Engagement

End-of-contract HSE scorecard; lessons-learned; re-engagement decision integrated with procurement database.

Implementation flow

Element-implementation flow chart

Decision-gated workflow showing the actual sequence of activities — from initiation through steady-state operation — with key decision points highlighted.

Start

Procurement raises contractor engagement requirement

Pre-Qualification per (h)(2)(i)

TRIR, OSHA history, insurance, training records

Decision

Threshold Met?

Decision gate

Hazard Info Comm per (h)(2)(ii)

Process hazards, evacuation, PTW system

Pre-Job Orientation per (h)(2)(iii)

Site induction + JSA review + PPE issue

Active Work Supervision

Tier-appropriate intensity per (h)(2)(v)

Injury Tracking per (h)(2)(iv)

TRIR / LTIFR / OSHA recordable / near-miss

Decision

Performance Issue?

Decision gate

Corrective Action

Stop work + RCA + retraining + restart

Closeout Scorecard

Final HSE performance + lessons + re-engagement

Deliverables

What we produce

Contractor pre-qualification framework per (h)(2)(i)
Pre-mobilisation orientation package
Injury / illness tracking per (h)(2)(iv)
Periodic evaluation scorecard
Tier-appropriate supervision plan
Closeout review protocol

Common pitfalls

Where execution fails

Pre-qualification done once but not refreshed
Orientation as box-tick without comprehension verification
Periodic evaluation skipped — same poor contractors re-engaged
Tier classification ignored under turnaround time pressure
