Why warehouse workers are at risk

OSHA lists forklifts, docks, conveyors, materials storage, manual lifting and heat among the main hazards in warehousing. Picking targets can drive a fast, repetitive pace that leaves little time to lift well or recover. HSE manual handling guidance asks employers to design out hazardous handling and to assess what remains. Large buildings with limited cooling can become hot in summer, and new or returning workers are the most vulnerable to heat illness.

01Back and shoulder injuries from picking and lifting

Lifting from floor level or above shoulder height, twisting while holding a load and carrying it far are particularly risky. Repetition across a long shift adds cumulative strain even when each item is light.

What helps

  • Pick heavy items from waist-height slots and store them there where you have a say.
  • Use lift-assist equipment, trolleys and conveyors rather than carrying.
  • Keep loads close, avoid twisting, and get help with awkward items.
  • Report pick rates that do not leave time to handle safely.

02Forklifts and moving vehicles

Collisions between forklifts and pedestrians, and loads falling from forks or racking, cause serious injuries. OSHA requires forklift operators to be trained and evaluated, and good layout separates people from vehicles.

What helps

  • Use marked pedestrian routes and make eye contact with drivers before crossing.
  • Only operate a forklift if trained and authorised.
  • Never walk under raised forks or loads.
  • Report damaged racking and blocked aisles immediately.

03Heat and long, repetitive shifts

Physical work in hot buildings raises the risk of heat exhaustion and heat stroke. OSHA advises water, rest and shade, with gradual build-up for workers new to the heat. Long shifts of repetitive work also lead to fatigue, which increases mistakes.

What helps

  • Drink water every 15 to 20 minutes in hot conditions, before you feel thirsty.
  • Take rest breaks in cooler areas and wear light, breathable clothing.
  • Watch colleagues for signs of heat illness.
  • Ease into full workload over your first week or after time off.

Weekly checklist for warehouse workers

  • Warm up hips, back and shoulders for five minutes before a shift.
  • Carry a water bottle and refill it at each break.
  • Wear supportive, safety-rated footwear and replace it when worn.
  • Rotate tasks where possible during the shift.
  • Do two short strength sessions on days off.
  • Log any near-miss with vehicles or falling objects.

When to see a professional

  • Back, shoulder or knee pain lasting more than a few weeks.
  • Pain, numbness or tingling in arms or legs.
  • Repeated headaches, dizziness or nausea at work in hot weather.
  • Foot pain that does not settle with rest.

Confusion, collapse, very hot skin or stopping sweating at work can be heat stroke: call emergency services and start cooling the person immediately.

Common questions

What is the most common injury in warehouses?

Musculoskeletal injuries to the back, shoulders and knees from lifting, carrying and repetitive movement are among the most common.

Do back belts prevent lifting injuries?

There is no good evidence that back belts prevent injury in healthy workers. Reducing load, height, distance and twisting through design and equipment is more effective.

How much water should I drink on a hot shift?

OSHA advises drinking about one cup every 15 to 20 minutes during hot, physical work, rather than waiting until you are thirsty.
