“Even for a minority of fit, well-trained individuals working under favourable conditions, operations which exceed guideline figures by more than a factor of about two may represent a serious risk of injury. Such operations should come under very close scrutiny.”
“For pushing and pulling operations (whether the load is slid, rolled or supported on wheels) the guidance figures assume the force is applied with the hands between knuckle and shoulder height. The guideline figure for starting or stopping the load is a force of about 25 kg (ie about 250 Newtons) for men and about 16 kg (ie about 160 Newtons) for women. The guideline figure for keeping the load in motion is a force of about 10 kg (ie about 100 Newtons) for men and about 7 kg (ie about 70 Newtons) for women.”
