Lower order machinery and equipment risk controls, such as personal protective equipment (PPE), can prevent injuries, but are generally not as effective as higher order controls, as they rely more on worker behaviour, maintenance programs and supervision.
Where access to the hazard is infrequent, the installation of a fitted guard, that can be removed by use of a tool, may be an acceptable control, where the tool to remove the barrier or guard is not normally available to the operator.
When assessing machinery and equipment for possible non-mechanical hazards, consider how machinery and equipment can affect the area (environment) around them. People must be provided with safe access that is suitable for the work they perform in, on and around machinery and equipment.
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.
