Risk Control

The hierarchy of control is a risk management strategy used to reduce the risk of harm or injury in the workplace. It is a systematic approach that prioritizes the most effective ways to eliminate or minimize workplace hazards. The hierarchy of control consists of five levels, ranked from most effective to least effective:

1. Elimination: The most effective way to control a workplace hazard is to eliminate it completely. This can be done by designing the work process or environment in such a way that the hazard no longer exists.

2. Substitution: If it is not possible to eliminate the hazard, the next best option is to substitute it with a less hazardous substance or process. For example, replacing a toxic chemical with a less harmful one.

3. Isolation: This involves isolating the hazard from the workers. This could be achieved by using barriers or enclosures to separate workers from the hazard or by changing the layout of the workplace to minimize exposure.

4. Engineering controls: This involves modifying the workplace environment or equipment to reduce exposure to the hazard. Examples include installing ventilation systems or guards on machinery.

5. Administrative controls: These are changes to work policies or procedures that aim to reduce the risk of harm. Examples include training workers on safe work practices, implementing work schedules or work rotations to minimize exposure to hazards, and posting warning signs.

6. Personal protective equipment (PPE): This is the last line of defence in the hierarchy of control. PPE includes items such as safety goggles, hard hats, and gloves that are worn by workers to protect them from hazards. While PPE can be effective, it is considered the least effective control measure because it relies on worker compliance and may not be able to completely eliminate the hazard.

By following the hierarchy of control, employers can systematically evaluate and address workplace hazards, reducing the risk of harm to their workers.
