Machinery and equipment have moving parts. The action of moving parts may have sufficient force in motion to cause injury to people. When assessing machinery and equipment for possible mechanical hazards, consider: machinery and equipment with moving parts that can be reached by people; machinery and equipment that can eject objects (parts, components, products or waste items) that may strike a person with sufficient force to cause harm; machinery and equipment with moving parts that can reach people, such as booms or mechanical appendages (arms); mobile machinery and equipment, such as forklifts, pallet jacks, earthmoving equipment, operated in areas where people may gain access.
In some cases, people exposed to these hazards may not show signs of injury or illness for years. Where people are at risk of injury due to harmful emissions from machinery and equipment, the emissions should be controlled at their source.
Machines are used broadly in the field of mechanics. The word mechanical refers to the work that has been produced by machines or the machinery. It mostly relates to the machinery tools and the mechanical applications of science.
Workplace managers may not have considered or recognised the need to provide similar means to gain safe access to parts of machinery and equipment at height, or in awkward locations for maintenance, repair, service or cleaning activities. Safe access at height can be broken into three categories. Each category has in common the need to provide a stable, safe platform suitable for the work to be undertaken, and to be equipped to support and retain a person within the confines of the platform.
