When pushing or pulling a load, the Health and Safety Executive provides the following guidance:
• Use an aid with a handle height that is between shoulder and waist height.
• Ensure that pushing or pulling equipment is well maintained.
• As a guide, the amount of force that needs to be applied to move a load over a flat surface is at least 2% of the load weight. For example, if the load is 400kg, then the force needs to be 8kg.
• The force for pushing or pulling will be greater over imperfect conditions.
• Always try to push rather than pull where possible.
• When negotiating a slope or ramp, get help from another worker.
• On an uneven surface, increase the pushing/pulling force to 10% of the load weight.
• To make it easier to push or pull, keep your feet well away from the load and move no faster than walking speed.
