Where exposure to machinery and equipment hazards cannot be eliminated or substituted for machinery and equipment of improved design, risk controls must be applied to the hazards to prevent or reduce the risk (chance) of injury or harm.
There are legal requirements that must be observed prior to allowing people to enter a confined space. • Training in confined space entry. • Issue of entry permits. • Continuous monitoring and supervision.
People performing tasks, such as maintenance, repair, installation, service and cleaning, are highly vulnerable, and have a higher risk of being killed or maimed through inadvertent operation of machinery and equipment they are working in, on or around.
People providing cleaning services could: • work alone • access machinery and equipment from the rear or sides, or in unexpected ways • climb on machinery and equipment • enter confined spaces, or larger machinery and equipment • become trapped by the mechanism of the machinery and equipment through poor isolation of energy sources or stored energy, such as spring-loaded or counter-balance mechanisms, compressed air or fluids, or parts held in position by hydraulics or pneumatic (air) rams • work with chemicals • operate electrical equipment in wet areas.
