Most forklift safety rules assume a steady state: the same aisles, the same loads, the same routes, every shift. The incidents that surprise safety teams cluster where that assumption breaks, in the infrequent jobs. Non-routine tasks include spill and debris cleanup, clearing a jammed conveyor or a fallen load, moving a single oversized or awkward item, helping maintenance with a repair, clearing snow or ice from a dock, setting up a temporary line or an event, and operating a borrowed or rental truck for a one-off move. These jobs are rare, so they are rarely rehearsed, and they often happen in places and conditions the daily routine never touches.
The risk is not just perception. Research on infrequent operations is blunt: the U.S. Chemical Safety Board reports that process safety incidents occur five times more often during startup than during normal operations, and a refining-industry study cited by the board found that 50 percent of process safety incidents occur during startups, shutdowns, and other infrequent activities, even though those periods are a small share of operating time (snapshot 2026-10-04). National fatality data points the same way. Of the 5,070 fatal work injuries recorded in the United States in 2024, transportation incidents were the largest single event type at 38.2 percent, and the transportation and material moving occupational group accounted for 1,391 deaths (snapshot 2026-10-04). Many of those events happen during maintenance, equipment movement, and altered traffic patterns rather than during routine production.
Why non-routine work raises risk
Four mechanics repeat across industries, as the safety analytics firm Intenseye describes in its analysis of non-routine work. First, temporary barriers and staging shift walkways and sightlines, so the separation a site relies on is not where it was yesterday. Second, workers enter zones they rarely visit and do not know the local hazards of. Third, contractors and internal teams overlap on the same task, and they do not share the same routines or briefing. Fourth, timelines are tighter, so exposure builds quickly and often without anyone recording it. The predictable environment that ordinary safety controls assume simply stops existing for the duration of the job.
What the standards already require
OSHA does not have a separate non-routine task standard, but 29 CFR 1910.178 already reaches most of the problem. The workplace-related training topics at 1910.178(l)(3)(ii) require operators to know surface conditions (A), load composition and stability (B), load manipulation, stacking and unstacking (C), pedestrian traffic (D), narrow and restricted places (E), ramps and slopes (G), ventilation in closed environments (H), and, at (l)(3)(ii)(I), any other unique or potentially hazardous environmental condition that could affect safe operation. That final item is the hook for infrequent work: an unfamiliar task in an unusual location is precisely a unique or potentially hazardous environmental condition. The truck itself is covered by 1910.178(q)(7), which requires an examination before the truck is placed in service and at least daily, and after each shift where trucks run round the clock. That rule matters most when a rental or loaner truck appears for a one-off job, and the inspection requirements guide walks through the daily check. Where the task touches equipment that stores energy, the maintenance and isolation duties in 1910.147 apply, which the lockout/tagout guide covers in detail.
A control framework for non-routine tasks
The fix is to stop treating a one-off job as an errand and plan it like any other task. A short pre-task briefing or job hazard analysis, done for the specific job rather than the routine, surfaces the conditions that change: the surface, the load, the people, the space. Work outside normal operation should be authorized, so someone other than the person doing the job has agreed it is safe to start. Temporary barriers, cones, signage and a spotter restore the separation that the task removed. Before the truck moves, confirm its capacity plate and its daily examination, especially when the truck is not one the operator normally drives, which the rental safety guide treats as a first question. Where the job touches a machine or an energy source, isolate the energy. Keep an experienced person supervising, because the board’s guidance for infrequent operations asks for trained supervision during startups and shutdowns, and it adds fatigue limits for turnarounds, on the reasoning that people are poor self-assessors and are less likely to admit they are too tired to work safely. The risk assessment guide and the hierarchy of controls guide give the ranking that keeps these controls in order.
Training and records
Non-routine work is a training gap as much as a planning gap. The refresher triggers at 1910.178(l)(4)(ii) already include an accident or near miss (B) and assignment to a different type of truck (D), so a one-off job that goes wrong should pull the operator back into training rather than be filed as bad luck. The maintenance guide and the safety rules guide show how a site can fold these triggers into its normal review, and the accident investigation guide covers what to record when an infrequent task becomes an event.
Where technology helps
Temporary conditions are exactly where detection earns its place, because the layout that a site designed around is not the layout the task creates. Vehicle-mounted proximity detection and camera systems can warn an operator and a pedestrian when a task has moved people into a travel path, and the event logs they produce give a supervisor something to review after a near miss. The severe-injury patterns this site publishes show that struck-by and caught-between events dominate serious outcomes, which the SIF prevention guide connects to the same infrequent-task exposure.
The starting point is to score the operation rather than guess. Run the Risk Scorer to see where exposure sits, compare the control families on the systems index, and when you are ready for vendor numbers, send your scope through the quote form. The methodology page documents how the scorer derives its inputs, and your state’s injury series shows the local context.
