Why it matters

Manual handling means lifting, lowering, carrying, pushing or pulling a load by hand. Most of your crew do it every shift. Few of them think of it as a hazard.

The WSH Council lists work-related musculoskeletal disorders among Singapore's top three occupational diseases. The back takes most of the strain. Damage often builds over months of awkward lifts. A single heavy lift can also tear a disc in one second.

A bad back can keep a worker off the tools for weeks. Some never return to heavy work.

Spot the risk factors

Weight alone does not decide the risk. Look at the whole task. A light box lifted from the floor 300 times a shift can hurt more than one heavy lift with good posture.

  • The task: lifting below knee height or above the shoulder, reaching out, twisting, long carries, frequent repeats.
  • The load: heavy, bulky, hard to grip, unstable, or with contents that shift, such as a half-full drum.
  • The place: tight space, uneven or wet floors, steps, slopes, poor lighting, heat.
  • The person: past back injury, new to the job, tired, unwell, or pregnant.

Order of controls

Work down the hierarchy of control. Stop at the first step that removes or cuts the risk. Training a worker to lift well does not make a 50 kg sack safe.

  • Eliminate: deliver materials to the point of use. Use conveyors or crane lifts so nobody carries the load.
  • Engineering: trolleys, pallet jacks, scissor lift tables, hoists, vacuum lifters. Raise work to waist height.
  • Change the load: order smaller bags and lighter cartons. Add handles. Split loads.
  • Administrative: team lifts for heavy or bulky items, job rotation, rest breaks, a clear route.
  • Training and PPE: lifting technique, gloves for grip and sharp edges, safety boots.
Ask the buyer

Many lifting problems start at purchase. Ask suppliers for cement, tiles or chemicals in smaller packs. You remove the risk before it reaches site.

Safe lifting technique

Teach this for the lifts you cannot remove. The steps below follow the WSH Council ergonomics guidelines.

  • Check the weight first. Rock or tip the load to feel it. Clear the route.
  • Stand close. Put one foot beside the load and one behind it.
  • Bend your knees and keep your back straight. Spread your weight across both feet.
  • Grip firmly and hold the load close to your body.
  • Push up with your legs. Do not jerk the load.
  • Turn with your feet, not your waist. Set the load down the same way you lifted it.

Team lifts, pushing and pulling

A team lift is not two single lifts at once. Pick people of similar height and strength. One person calls the lift. Everyone lifts, moves and lowers on that call. Agree the route and the drop point before anyone takes the weight.

Pushing is usually easier on the body than pulling. A loaded trolley still needs care. Check the wheels turn freely and the tyres hold air. Keep the load low enough to see over. Go slow on ramps, and get a second person for steep slopes or heavy loads.

What the rules require

Under the WSH (Risk Management) Regulations, every workplace must assess the safety and health risks of its work. The assessment must be done before work starts. You must take reasonably practicable steps to remove each foreseeable risk. Where you cannot remove it, you must reduce it through the hierarchy of control. This comes from the WSH Guidelines on Improving Ergonomics in the Workplace.

MOM expects you to review the risk assessment at least every three years. Review it sooner after an incident, a process change or new equipment (MOM FAQ).

SS 569:2011, the Code of Practice for Manual Handling, is an approved code of practice. MOM points to it as the reference for acceptable manual handling practice. It gives recommended lifting limits that change with the load and the task (MOM FAQ).

Legal requirement

Work-related musculoskeletal disorder of the upper limb is a reportable occupational disease. The employer must send the doctor's written diagnosis to the Commissioner for WSH within 10 days of receiving it, through iReport. Source: WSH Council ergonomics guidelines.

Watch for early signs

Most back and shoulder injuries give warnings. Workers mention stiffness, aches at the end of the shift, or numb fingers. Some start lifting with one arm or stop bending.

Ask your crew to report pain early. Early reports let you change the task before the damage sets in. Send anyone with ongoing pain to a doctor and adjust their work while they recover.

Common mistakes

These are the faults that show up most often on site walks.

  • Treating a lifting talk as the main control while trolleys sit unused.
  • Using one weight figure for every lift, whatever the height, reach or repetition.
  • Leaving manual tasks out of the risk assessment because they look routine.
  • Storing heavy items on the floor or the top shelf instead of at waist height.
  • Pairing up workers for a team lift with no one calling the lift.
  • Rushing deliveries at the end of the day, when people are tired.
Back belts are not a control

Do not hand out back support belts in place of fixing the task. They do not reduce the load on the spine and can give false confidence.

In other countries

  • Malaysia: Section 12 of the Factories and Machinery Act 1967 bars employing a person to lift, move or carry a load heavy enough to cause injury. DOSH's Guidelines for Manual Handling at Workplace 2018 give recommended weights. They cut those weights for frequent lifts and for twisting. For example, lifting five to eight times a minute halves the figure.

Use it on site: the manual handling checklist and the toolbox talk to brief your crew.
