Temporary and seasonal workers are a growing share of warehouse labor, and they are overrepresented in forklift incidents. The reasons are structural: short tenure on the job, limited familiarization with a specific facility, and pressure to be productive immediately. OSHA is explicit that host employers and staffing agencies share responsibility for temporary worker safety. This post covers how to train, supervise, and track temporary forklift operators so that short tenure never means lower safety.
Why temporary operators carry higher risk
BLS fatality data shows that workers in their first year on the job are consistently overrepresented among fatal occupational injuries, and powered industrial trucks remain one of the leading sources of those fatalities. For temporary workers the risk is compounded: they are new not just to the job but to the facility, the equipment model, and the site’s traffic patterns. Inexperience plus unfamiliarity plus production pressure is the combination that produces incidents.
The practical implication is that temporary operators need more supervision and more deliberate onboarding than permanent staff, not less. Many facilities make the mistake of treating a temporary operator’s certification as sufficient evidence of readiness. Certification is the baseline; site readiness is a separate step.
Shared responsibility between host and agency
OSHA’s position is that staffing agencies and host employers are jointly responsible for temporary worker safety. The agency must verify the worker is qualified for the assignment, and the host must provide the site-specific training, equipment, and supervision. For forklifts, that means the staffing agency is responsible for confirming that the operator holds valid forklift certification, and the host is responsible for the site-specific training required by OSHA 29 CFR 1910.178(l).
Put the split in writing before the worker arrives. A simple agreement that names who verifies certification, who provides site orientation, who supplies PPE, and who conducts the practical evaluation prevents the classic gap where each party assumes the other handled it. When an incident happens, the first question from an investigator is which party owned each piece of the safety chain, and an undocumented split is a liability for both sides.
A practical onboarding sequence for temporary operators
Treat the first days of a temporary assignment like a staged qualification, not an orientation video. A workable sequence:
- Verify documentation before the first shift: current certification, any medical restrictions, and language considerations.
- Site orientation: walk the temporary operator through the facility covering pedestrian walkways, blind spots, speed zones, and emergency procedures.
- Equipment familiarization: have the operator demonstrate operation of the exact model they will use, including the daily inspection checklist, before they run it with a load.
- Supervised operation: keep the operator under direct observation for the first few shifts, with a mentor operator or supervisor available.
- Assess and release: only release the operator to independent work after a documented evaluation, which satisfies the evaluation requirement in 1910.178(l).
Supervision and monitoring during the assignment
Temporary operators need the same monitoring as permanent staff, and ideally more during the first weeks. Check in on them during shifts rather than only at the end. Watch for the behaviors that predict incidents: unsafe acts like speeding, distracted operation, or skipping the daily inspection. Corrective feedback should be immediate and documented, because a temporary operator who learns a bad habit in week one will carry it for the whole assignment.
Use your near-miss reporting system to track whether temporary operators are reporting or going quiet. A temporary operator who is involved in near misses early is not necessarily a problem operator; they may be the ones actually paying attention. But a pattern of unreported at-risk behavior is a signal that supervision needs to tighten.
Data and tracking for a fluctuating workforce
Temporary workforces change constantly, which makes recordkeeping harder and more important. Track each temporary operator in your safety management system: certification expiry dates, site orientation completion, evaluation results, and incident history. When an assignment ends, the record stays with the worker’s file so the next facility can verify their status. When a temporary worker returns for a later season, the record shows what training is still current and what needs refresh.
Certification expiry is a particular trap with temporary workers, because they may rotate between agencies and facilities. Set up expiry alerts in your system so nobody operates a forklift past their certification date. OSHA 29 CFR 1910.178(l) requires refresher training when an operator is observed operating unsafely, is involved in an accident, or receives an evaluation finding, so document those triggers for every temporary operator just as you would for permanent staff.
Building temporary safety into the program
The facilities that handle temporary workers well treat them as first-class members of the safety program, not as a separate, lower bar. That means the same forklift safety rules, the same PPE standards, the same daily inspection discipline, and the same rights to report hazards. A temporary worker who does not feel authorized to stop an unsafe situation is a worker who will accept risk they should not accept.
Use the Risk Scorer to assess how your temporary workforce changes exposure: more operators on the floor, more people learning traffic patterns, more bodies in pedestrian zones. Score the busiest periods, then put controls where the score is highest. A facility that scores its temporary surges and staffs the supervision to match is a facility that keeps its seasonal spike from becoming its incident spike.
