The Contractor Safety Challenge

Contractors perform essential work at facilities across all industries. However, they also present unique safety challenges. OSHA data shows that contract workers experience higher injury rates than direct employees in many industries.

Why Contractor Safety Matters

Regulatory requirements:

  • OSHA's multi-employer worksite policy holds host employers responsible for hazards affecting contractors
  • Process Safety Management (PSM) requires contractor safety programs
  • Many industry standards require contractor oversight
  • Business reasons:

  • Contractor injuries can result in OSHA citations for the host employer
  • Liability exposure for incidents involving contractors
  • Work stoppages and project delays
  • Reputation damage
  • Insurance implications
  • Legal Framework

    Multi-Employer Worksite Doctrine

    OSHA can cite employers in four categories:

  • **Creating employer** - Caused the hazardous condition
  • **Exposing employer** - Workers exposed to the hazard
  • **Correcting employer** - Responsible for correcting the hazard
  • **Controlling employer** - Has authority to correct or require correction
  • Host employers are often cited as controlling employers even when contractors created the hazard.

    Contractual Doesn't Equal Liability Transfer

    Common misconceptions:

  • "The contractor is responsible for their own safety" - Legally insufficient
  • "We have indemnification clauses" - May not prevent OSHA citations
  • "They're independent contractors" - Doesn't eliminate duty of care
  • Building a Contractor Safety Program

    Pre-Qualification

    Evaluate contractors before they work at your site:

    Safety performance data:

  • OSHA 300 logs for past three years
  • Calculate EMR (Experience Modification Rate)
  • TRIR (Total Recordable Incident Rate)
  • DART rate
  • Compare to industry averages
  • Program documentation:

  • Written safety programs
  • Training records
  • Drug testing program
  • Insurance certificates
  • Minimum standards to consider:

  • EMR below 1.0 (or your threshold)
  • TRIR below industry average
  • Required safety programs in writing
  • Adequate insurance coverage
  • Contract Requirements

    Include safety requirements in contracts:

    General provisions:

  • Compliance with all applicable regulations
  • Compliance with site-specific rules
  • Right to audit and inspect
  • Incident reporting requirements
  • Right to stop work for safety violations
  • Specific requirements:

  • Required PPE
  • Hot work permits
  • Confined space procedures
  • Lockout/tagout coordination
  • Fall protection requirements
  • Insurance requirements:

  • Workers' compensation coverage
  • General liability minimums
  • Additional insured endorsements
  • Certificates before work begins
  • Site Orientation

    All contractor personnel should receive:

    Site-specific information:

  • Emergency procedures and assembly areas
  • Hazard communication (chemicals on site)
  • Reporting requirements
  • Restricted areas
  • Permit requirements
  • Acknowledgment documentation:

  • Sign-in confirming orientation completion
  • Acknowledgment of site rules
  • Agreement to comply with requirements
  • Coordination and Communication

    Daily coordination:

  • Pre-work meetings when multiple contractors work simultaneously
  • Communication of changing conditions
  • Coordination of hazardous work activities
  • Permit systems:

  • Hot work permits
  • Confined space entry permits
  • Excavation permits
  • Energized electrical work permits
  • Hazard communication:

  • Share information about site hazards
  • Ensure contractors share information about hazards they create
  • Update when conditions change
  • Monitoring and Oversight

    Regular monitoring activities:

  • Safety observations during work
  • Documented inspections
  • Review of incident reports
  • Periodic audits of contractor safety programs
  • Authority to act:

  • Stop unsafe work immediately
  • Remove individuals violating safety rules
  • Require corrective action before work resumes
  • Contractor Pre-Work Meetings

    Before work begins, cover:

  • **Scope of work** - What will be done, where, and when
  • **Hazards** - Site hazards and job hazards
  • **Controls** - How hazards will be managed
  • **Permits** - What permits are required
  • **Communication** - How to report issues
  • **Emergency procedures** - What to do if something goes wrong
  • Document attendance and topics covered.

    Managing Contractor Incidents

    Immediate response:

  • Provide emergency assistance
  • Secure the scene
  • Notify appropriate personnel
  • Investigation:

  • Conduct joint investigation with contractor
  • Identify root causes
  • Determine if host employer factors contributed
  • Corrective action:

  • Address both contractor and site issues
  • Verify corrective actions are implemented
  • Share lessons learned
  • Documentation:

  • Document the incident even though it involves a contractor
  • Maintain records for your reference
  • Verify contractor OSHA recordkeeping
  • Annual Contractor Reviews

    Evaluate contractor performance annually:

    Metrics to track:

  • Incidents at your facility
  • Safety violations observed
  • Response to identified issues
  • Training compliance
  • Permit compliance
  • Performance discussions:

  • Share performance data with contractors
  • Discuss improvement opportunities
  • Set expectations for continued work
  • Consider removing poor performers
  • Special Considerations

    High-Hazard Work

    For particularly hazardous activities:

  • Consider requiring contractor safety plans specific to the job
  • Require competent persons for activities like excavation, scaffolding
  • Increase monitoring frequency
  • Require supervisor presence
  • Recurring Contractors

    For contractors who work regularly at your site:

  • Conduct periodic re-evaluation
  • Require refresher training annually
  • Include in your safety committees
  • Treat like employees for safety purposes
  • Multi-Tier Contractors

    When contractors hire subcontractors:

  • Flow down all safety requirements
  • Require notification of subcontractor use
  • Include subcontractors in orientation and oversight
  • Clarify responsibility for subcontractor safety
  • Common Program Deficiencies

    Frequently identified issues:

  • No formal pre-qualification process
  • Safety requirements not in contracts
  • Orientation inadequate or undocumented
  • Insufficient monitoring of contractor work
  • No process for addressing contractor violations
  • Failure to investigate contractor incidents
  • No periodic re-evaluation of contractors
  • Conclusion

    Effective contractor safety management requires systematic processes from pre-qualification through project completion. The investment in robust contractor oversight protects workers, limits liability, and improves project outcomes.
