English:Forklift Safety

Forklift Safety
Introduction
Forklifts, also called lift trucks or powered industrial trucks, move, lift, stack, and position materials in warehouses, factories, construction areas, yards, ports, and many other workplaces. They are extremely useful, but they can also injure operators and pedestrians through collisions, tip-overs, falling loads, crushing, or unsafe loading and unloading.
This aiMOOC is designed for apprentices, trainees, and vocational students. It helps you build the knowledge needed to recognise hazards and make safe decisions around forklifts. It does not by itself qualify or authorise you to operate a forklift. Real operation requires the training, supervised practice, workplace evaluation, and authorisation required by your employer and by the law where you work. Always follow the specific truck's operator manual, data plate, site rules, and instructions from a competent trainer.

A forklift does not handle like a car. Many common counterbalanced forklifts use rear-wheel steering, have a heavy counterweight, and can become unstable when the load, speed, slope, turning force, or surface conditions move the combined centre of gravity outside the truck's stable support area. Different forklift types have different controls and hazards, so competence on one truck does not automatically make you competent on another.
The SAIF Corporation video above gives an overview of inspection, load safety, movement, parking, pedestrians, loading areas, rough terrain, and tip-over prevention. Use it as learning support, not as a replacement for practical instruction.
Learning Goals
By the end of this aiMOOC, you should be able to:
- Forklift fundamentals: Explain why a forklift behaves differently from a road vehicle.
- Hazard recognition: Identify common forklift hazards in a real or simulated workplace.
- Pre-use inspection: Describe what should be checked before a truck is used and what to do if a defect is found.
- Load handling: Use the data plate and basic stability principles to judge whether a planned lift is safe.
- Pedestrian protection: Explain how traffic separation, visibility, communication, and right-of-way rules reduce struck-by risks.
- Safe operation: Describe safe travel, parking, slope, dock, charging, and fueling practices.
- Professional responsibility: Explain why operator training, supervision, site rules, and refresher training matter.
Forklift Fundamentals
Main Parts and Functions
A typical counterbalanced forklift includes forks or another approved attachment, a mast, lift chains or cylinders, a carriage, an overhead guard, an operator compartment, steering and braking controls, drive wheels, steer wheels, and a counterweight. The exact design varies. Reach trucks, order pickers, powered pallet trucks, rough-terrain forklifts, and other industrial trucks may handle very differently.
The forks support the load. The mast raises and lowers the carriage. The counterweight helps balance the load on a counterbalanced truck. The overhead guard helps protect the operator from some falling small objects, but it does not make it safe to stand or travel under a raised load. The data plate or capacity plate states important rated limits and configurations. Attachments, unusual load centres, high lift heights, or altered truck configurations can reduce or change capacity.

The warning sign above is ISO 7010 W014, used to warn people about fork lift truck traffic. A sign is useful only when workers also understand the traffic plan and follow it.
Stability and the Centre of Gravity
Think of stability as a balance problem. On many counterbalanced forklifts, the truck and its load form a combined centre of gravity. As a load becomes heavier, moves farther forward, is raised higher, or is affected by turning and braking forces, the stability margin can become smaller. Slopes, potholes, dock edges, uneven surfaces, and sudden manoeuvres can make this worse.
The practical lesson is simple: respect the rated capacity, keep the load stable and as low as practical during travel, move smoothly, and avoid sudden turns or stops. Never guess the capacity of a truck. Read the data plate and use the load centre and attachment information specified for the machine. If a load or configuration is outside the rated information, stop and ask a competent person.
Raising a load changes stability as well as visibility. A forklift that feels stable with the forks low can become unstable with the same load raised. Do not travel with a load unnecessarily high, and do not use raised forks as a platform for people.
Why Training Is Machine-Specific and Site-Specific
Forklift safety depends on both the machine and the workplace. A trained operator needs to understand the truck's controls, steering, visibility, braking, capacity, attachments, inspection points, and operating limits. The operator also needs to understand site hazards such as pedestrians, narrow aisles, doors, ramps, docks, trailers, poor lighting, floor damage, overhead obstructions, and hazardous atmospheres.
In the United States, OSHA requires powered industrial truck training to combine formal instruction, practical training, and evaluation of operator performance in the workplace. In the United Kingdom, HSE guidance likewise emphasises basic training, job-specific training, familiarisation training, monitoring, and refresher training. Requirements differ by country, so your local law and employer procedures always control.
Pre-Use Inspection
A pre-use inspection is a safety decision, not a paperwork ritual. The exact checklist comes from the manufacturer and your workplace. You should know what your site requires before each shift or use.
A typical visual check can include the forks, locking pins, carriage, mast, chains, hoses, cylinders, tyres or wheels, overhead guard, seat and operator restraint, battery or fuel system, visible leaks, warning labels, and obvious structural damage. Check that the area around the truck is clear before starting it.
An operational check can include the steering, service brake, parking brake, horn, lights, warning devices, instruments, lift and tilt controls, and other functions listed by the manufacturer. Listen and look for anything abnormal. If a defect could affect safe operation, do not use the truck. Isolate or tag it according to site procedure and report the defect to the responsible person.

Battery condition and electrical systems are part of safe equipment management. Inspection, testing, charging, repair, and battery handling must follow the manufacturer's instructions and site procedures and may require specifically trained personnel.
Safe Travel and Manoeuvring
Before Moving
Mount and dismount using the handholds and steps provided. Keep hands free where possible and face the truck when using three points of contact. Adjust the seat and mirrors where fitted, fasten the operator restraint when required, confirm the travel path is clear, and make sure no person is in the truck's danger zone.
Keep forks or the load only as high as necessary for safe ground clearance while travelling. Look in the direction of travel. If the load blocks your forward view, use the safe method taught for that truck and site, such as travelling in reverse where appropriate and permitted or using a trained spotter. Never move simply because you expect a pedestrian to get out of the way.
Speed, Turning, and Visibility
Use a speed that allows you to stop safely within the visible clear distance. Slow down for corners, crossings, doorways, wet floors, loose material, rough ground, congested areas, and changing light. Avoid sudden steering, acceleration, or braking.
Many forklifts have rear-end swing because of rear steering. A turn that clears the front of the truck can still swing the rear into a rack, wall, vehicle, or person. Give the truck enough space and check both the travel path and the tail-swing area.
Sound the horn or use the site warning method at blind corners and intersections when required, but never treat a horn as a substitute for visibility or separation.
Pedestrians and Shared Work Areas
Pedestrians can be hidden by the mast, load, racking, doorways, or other vehicles. They may also misjudge a forklift's turning path or braking distance. The strongest protection is to design the workplace so people and vehicles do not have to occupy the same space.

The image above shows an industrial barrier absorbing an impact from a forklift. Physical separation can reduce pedestrian exposure, but barrier type, placement, strength, and maintenance must be selected for the actual site and vehicle risks.
Use physical barriers, marked walkways, controlled crossings, separate doors, speed limits, mirrors, lighting, and one-way systems where appropriate. At crossings, both operator and pedestrian should make sure they have been noticed before either enters the conflict area. Pedestrians should never walk under raised forks or loads and should stay clear of the truck's rear swing and crushing zones.
The WorkSafeBC video above demonstrates how limited a forklift operator's field of vision can be and why pedestrian awareness matters.
Loads, Capacity, and Stacking
Before lifting, identify the load's weight, dimensions, stability, and centre. Make sure the pallet or container is sound enough for handling. Compare the planned lift with the truck's data plate and the approved attachment configuration. Never add people or improvised counterweights to increase capacity.
Approach a load squarely. Set the fork spacing to support the load, insert the forks as fully as practical, and keep the load centred. Tilt only as required by the truck's procedure. Secure or re-pack unstable material before moving it. Do not try to catch or stabilise a falling load with your hands or body.
When stacking, confirm that the rack, floor, pallet, or stack can support the load. Position the truck carefully, raise only when stable and correctly aligned, place the load without forcing or damaging the rack, then withdraw the forks cleanly before lowering them for travel. Keep people out of the stacking zone.

The symbol above reinforces a basic rule: never stand beneath raised forks or an elevated load.

The image above shows palletised cargo being handled into a shipping container. Confined spaces add visibility, clearance, ventilation, trailer stability, and pedestrian-control considerations.
Docks, Trailers, and Loading Areas
Loading docks combine vehicle movement, edges, dock plates, trailers, pedestrians, and changing surfaces. Before entering a trailer, follow the site's procedure for preventing the trailer from moving. Check that the floor and dockboard or bridge plate are suitable and rated for the combined load. Check trailer condition, lighting, clearance, and any required supports or restraints.
Never drive toward an unprotected dock edge without a safe stopping margin. Keep the work area clear and do not assume a truck driver knows a forklift is inside the trailer.

Slopes, Ramps, and Uneven Ground
Slopes change the position of the combined centre of gravity and can reduce traction. Use only routes approved for the truck. Travel slowly, keep a safe distance from edges, avoid turning on a slope, and follow the manufacturer's and site's rules for travel direction.
For many counterbalanced forklifts, a loaded truck is kept with the load upgrade on a significant slope, while an unloaded truck is commonly oriented so the forks point downgrade. Because truck types and site rules differ, learn the exact slope procedure for the machine you are authorised to use rather than applying a memorised rule to every vehicle.
Do not cross potholes, loose debris, damaged dock plates, weak floors, or other surface defects that could destabilise the truck. Report hazards and use a safe alternative route until they are corrected.
Parking, Charging, and Fueling
Safe Parking
Park only in an approved place that does not block exits, emergency equipment, walkways, or traffic routes. Lower the forks or attachment fully, neutralise the controls, set the parking brake, and switch off the power as required by the manufacturer and site procedure. Remove the key or otherwise prevent unauthorised use where required.
If parking on an incline cannot be avoided, follow the site's wheel-blocking or securing procedure. Never leave a forklift in a condition where someone can walk into raised forks.
Battery Charging and Fueling
Charging and fueling create additional hazards. Lead-acid batteries can involve corrosive electrolyte and hydrogen gas. Lithium-ion batteries require correct chargers, temperature control, damage monitoring, and manufacturer-specific emergency procedures. LPG, gasoline, diesel, and other fuels introduce fire, pressure, or exhaust hazards.
Use only designated areas with the required ventilation, fire protection, spill controls, emergency equipment, and personal protective equipment. Shut down the truck as required before connecting a charger or changing fuel. Keep ignition sources away. Do not charge a damaged battery or attempt repairs unless you are trained and authorised.

A damaged traction battery is a clear reason to stop, isolate the equipment, and follow the site's battery incident procedure.
Tip-Over and Emergency Response
The best tip-over response is prevention: respect capacity, keep the load low, slow down before turning, avoid sudden manoeuvres, keep away from edges, and use the correct route for slopes and rough ground.
For a seated counterbalanced forklift fitted with an operator restraint, recognised safety guidance commonly teaches the operator to remain in the operator compartment, keep the restraint fastened, brace, and lean away from the direction of the tip instead of trying to jump. Emergency actions are truck-specific. Stand-up trucks and other designs may require different procedures, so follow the manufacturer's instructions and your practical training.
The WorkSafeBC video above focuses on staying in the operator compartment during a seated forklift tip-over and using the restraint system correctly.
After any collision, near miss, dropped load, tip-over, equipment damage, or suspected structural impact, stop work, secure the area, report the event, and follow the site's emergency and inspection procedures. Do not restart a damaged truck simply because it still moves.
Supervision, Communication, and Safety Culture
Safe forklift work is a team activity. Operators need clear rules, pedestrians need to understand traffic controls, supervisors need to monitor behaviour and conditions, and maintenance personnel need accurate defect reports. Near misses are valuable warning signals and should be reported without hiding or minimising them.
A good safety culture encourages workers to stop a task when conditions have changed or when they are unsure about capacity, visibility, clearance, load stability, or pedestrian control. Productivity never justifies bypassing a safety control.

Evidence of Learning
Important evidence of learning includes knowledge: you can explain forklift stability, capacity, visibility, traffic separation, inspection, safe travel, parking, and charging or fueling risks.
It includes skills: you can read a sample data plate, identify hazards in a workplace plan, complete a trainer-approved inspection process, communicate with pedestrians and supervisors, and stop a task when key safety information is missing.
It includes products: you can create a hazard map, inspection checklist, safety poster, interview summary, risk assessment, or short training resource that uses accurate safety language.
It includes transfer: you can apply the same safety principles to a new truck or site while recognising that authorisation, controls, operating limits, and legal requirements may change.
For practical competence, evidence must also include supervised performance on the actual truck and in the actual workplace when required by law or employer procedure. A written quiz alone is not proof of safe operating competence.
