Australia Model Code of Practice: Managing the Risks of Plant in the Workplace 2.3a: 2.3 Select plant controls using the hierarchy and check they do not create new hazards

The WHS Regulations require duty holders to work through the hierarchy of control for plant, which has specific controls for powered mobile plant, plant that lifts or suspends loads, tree lopping plant, industrial robots, lasers, pressure equipment, scaffolds and plant with presence-sensing safeguards. Always aim to eliminate the risk. If that is not reasonably practicable minimise it by substitution (for example a conveyor in place of forklifts, noting new hazards such as entanglement), isolation (barriers separating mobile plant and people, securing plant that could be used as a weapon or for self-harm), engineering controls (automatic brakes, anti-collision systems, interlocked guards, operator protective devices, wheel chocks, IT systems that reduce human error), then administrative controls (tag-out, user profiles, training), and last PPE. Administrative controls and PPE do not control the hazard at its source and tend to be least effective. Combine controls where one is not enough, check that controls do not introduce new hazards, and where controls change how work is done consult workers, develop safe work procedures and provide information, training, instruction and supervision.
