Equipment Operator Training & Evaluation

Heavy equipment is powerful and unforgiving. Many serious injuries involve operators who were never properly trained or evaluated on the machine they were running. Good training covers the machine, the site and the hazards, and an evaluation shows that the operator can do the job safely. Employers are responsible for both.

• Equipment
• Employers

What OSHA requires

• General construction rules: employers must instruct each employee in recognizing and avoiding unsafe conditions and the rules for their work (29 CFR 1926.21(b)(2)), and must permit only designated, trained or competent workers to operate machinery and equipment (1926.20(b)(4)). See Training Requirements.
• Powered industrial trucks (forklifts): OSHA requires training, a practical evaluation of the operator’s performance in the workplace, and a re-evaluation at least every three years (1910.178(l)). Operators must be trained and evaluated on each type of truck. See Forklifts.
• Cranes and derricks in construction: operators must be certified or qualified (for example certified by an accredited testing organization, or qualified through an employer program) and evaluated (1926.1427). See Crane Basics.
• Aerial lifts and MEWPs: operators must be trained to operate the lift. See Aerial Lifts and Scissor Lifts.
• Many other machines, such as excavators, loaders and dozers, have no single operator-training standard, but the general duty rules, state rules and the manufacturers’ manuals still require trained operators. Insurers and project owners often require more.

Check your state plan, since some states add requirements. See State Plans Overview.

What good training covers

• The machine: controls, instruments, safety devices, load charts, limits, attachments and daily checks. See Equipment Basics.
• Pre-use inspection: how to do a walk-around, what to look for and when to tag out. See Forklift Inspection.
• Safe operation: starting and stopping, travel, turning, loading, digging, lifting, working on slopes and parking.
• Hazards on the site: traffic, people on foot, overhead lines, buried utilities, soft ground, excavations and weather. See Work Zones, Backing & Spotters and Overhead Power Lines.
• Rollovers, tip-overs and struck-by hazards: how they happen and how to prevent them. See Equipment Rollovers and Struck-By & Caught-Between.
• Seat belts, mounting and dismounting, fueling and maintenance. See Equipment Fueling and Blocking & Cribbing.
• Emergency procedures: what to do if the machine contacts a power line, loses brakes, starts a fire or tips.
• Communication: hand signals, radios, spotters and site rules.

Evaluation: proving the skill

Training is not complete until the operator shows the skill. A solid evaluation includes:

1. Knowledge check: a written or oral test on the machine, the hazards and the rules.
2. Hands-on skills test on the same type of machine in realistic conditions, such as a driving course, a digging task or a load-handling exercise.
3. Observation on the job by a qualified evaluator, who watches how the operator inspects, starts, works around people and shuts down.
4. Clear pass criteria written in advance, with feedback and retraining for gaps.
5. Records showing who was trained, when, on what, by whom, and the result.

The trainer or evaluator should have the knowledge, experience and skill to train and judge operators. Many employers use manufacturer training, trade association programs, union apprenticeships or third-party certifications, and then add a site-specific evaluation. A certification card alone doesn’t cover the specific machine, attachment or site. See Safety Certifications.

Familiarization on each machine

• Every machine is a little different: controls patterns (such as ISO or SAE patterns on excavators), joystick layouts, load charts, blind spots and attachments. Even an experienced operator needs time to learn a new model.
• Give operators a familiarization session on each new machine or attachment before they work around others. Practice in an open area.
• Make sure the operator reads the operator’s manual and knows where to find it.
• Check attachment rated capacities and compatibility before use. See Forklifts and Telehandlers.

Refresher training and retraining

• Retrain and re-evaluate after an accident or near miss, if an operator is seen operating unsafely, if conditions or machines change, or if the operator is assigned to a different type of machine.
• For forklifts, re-evaluate at least every three years, and sooner when needed.
• Provide regular refreshers on topics such as rollovers, power lines and spotters. Use toolbox talks. See Toolbox Talks.
• Make sure training is in a language and format the operator understands. See Multilingual Crews.

Fitness and authorization

• Operators should be physically able to run the machine and must not be impaired by drugs, alcohol, fatigue or medication. See Fitness for Duty and Shift Work.
• Only authorized, trained operators should run equipment. Don’t let untrained workers “just move it.” Keep keys controlled.
• New workers should work under supervision while they gain experience. See Mentoring New Workers.

Operator training checklist

• Operator trained on this type of machine, and any attachment, with a written or oral knowledge check
• Hands-on evaluation completed and documented by a qualified evaluator
• Familiarization on the specific machine before working near others
• Certification or qualification on file where required, such as cranes
• Refresher and re-evaluation scheduled, and after any incident
• Only authorized operators have access to keys
