Question

explain the hierarchy of control in the workplace

Answer 1

Hierarchy of control' refers to the order of priority for preventive and protective measures when assessing the adequacy of existing controls or introducing new controls. It reflects the concept that risk elimination and risk control by the use of physical engineering controls and safeguards can be more reliably maintained than those which rely solely on people.

The hierarchy of control is a system for controlling risks in the workplace. The hierarchy of control is a step-by-step approach to eliminating or reducing risks and it ranks risk controls from the highest level of protection and reliability through to the lowest and least reliable protection.

Steps Involved

• Eliminate the Risk which is always preferred.
• Substitute the current system of work, equipment or substance with a lesser Risk.
• Use engineering controls, such as treatment or containment for Environmental Risks or machine safeguarding for Health and Safety Risks.
• Use administrative controls, such as warning signs, training, routine maintenance, specific documented procedures, work instructions, or adequate supervision.
• Conduct a Job Hazard/Safety Analysis and/or use personal protective equipment.
