Why Contractor Management Matters in PSM
Contractors often perform high‑risk tasks such as:
These activities frequently involve opening the process, introducing ignition sources, or changing equipment, making contractor safety a critical part of process safety.
🧑🏭
Host Employer Responsibilities
Episode 50 outlines several key obligations for facilities covered by PSM:
1. Evaluate Contractor Safety Performance
Before hiring contractors, the host employer must assess:
-
Injury and illness rates
-
Safety programs and training
-
Experience with similar processes
-
Past performance and references
This is not a paperwork exercise — it’s a risk filter.
2. Inform Contractors of Process Hazards
The host employer must communicate:
-
Fire, explosion, and toxic release hazards
-
Applicable emergency procedures
-
Safe work practices
-
Known hazards in the work area
Contractors cannot protect themselves from hazards they don’t know exist.
3. Ensure Contractors Follow Site Safety Rules
This includes:
The host employer must verify, not assume, compliance.
4. Maintain Injury and Illness Logs for Contractors
The facility must keep records of:
These records help evaluate contractor performance over time.
5. Periodically Evaluate Contractor Performance
The host employer must:
-
Review contractor safety behavior
-
Identify recurring issues
-
Remove contractors who fail to meet expectations
Contractor oversight is an ongoing responsibility.
🧰
Contractor Responsibilities
Contractors also have explicit duties under PSM:
1. Train Their Employees
Contractors must ensure their workers are trained on:
The host employer is not responsible for training contractor employees on their own company’s procedures.
2. Ensure Employees Follow Site Rules
Contractors must enforce:
Failure to follow site rules is a major cause of contractor‑related incidents.
3. Document and Communicate Hazards
Contractors must:
-
Inform the host employer of hazards they encounter
-
Report incidents and near misses
-
Coordinate work activities with operations
Communication is a two‑way street.
🧪
Common Failures Highlighted in the Episode
Dr. Ayers calls out typical breakdowns:
-
Contractors not informed of process hazards
-
Poor oversight during high‑risk work
-
Contractors bypassing permits or procedures
-
Inadequate training for contractor employees
-
Host employers assuming contractors “know what they’re doing”
-
Lack of coordination between operations and contractor crews
These failures often lead to fires, explosions, and toxic releases.
🧑🏫
Leadership Responsibilities
Safety leaders must:
-
Select contractors based on safety performance, not cost alone
-
Communicate hazards clearly and consistently
-
Verify contractor compliance with site rules
-
Ensure strong coordination between operations and contractor teams
-
Track contractor incidents and use them to improve oversight
-
Treat contractors as part of the process safety system
The episode’s core message: You can outsource work — but you cannot outsource risk.
