What
are the 5 hierarchy of control with examples?: The hierarchy of controls is a
classification of risk control methods based on their effectiveness. It is
commonly used in safety and health fields to prioritize interventions that
eliminate or minimize hazards. Here is a breakdown of the hierarchy with
examples.
Hierarchy of control examples
Elimination:
Definition:
Physically eliminate the danger.
Example:
Instead of using toxic chemicals in a cleaning process, switch to a non-toxic
alternative.
Substitution:
Definition:
Replacing the dangerous material or process with a less dangerous one.
Example:
Use a hand saw instead of a power saw to reduce noise and risk of injury.
Engineering controls:
Definition:
Isolate the hazard from the worker using physical barriers, ventilation systems, or other methods.
Example:
Install a local exhaust ventilation system to remove dust and fumes from a
sanding operation.
Administrative controls:
Definition:
Changing the way work is done to reduce exposure to hazards. This includes
procedures, training, work schedules, and signage.
Example:
Implement a job rotation system to minimize workers' exposure time to
repetitive tasks.
Personal Protective Equipment (PPE):
Definition:
Use PPE such as gloves, masks, goggles, or respirators to protect the worker
from danger. This is the least effective control and should only be used as a
last resort when other methods are not feasible.
Example:
Provide earplugs or earmuffs to protect workers from noise pollution.
Conclusion
Remember,
the higher up the hierarchy, the more effective the control method will be in
protecting workers from harm. It is crucial to prioritize removal and
replacement wherever possible, followed by administrative and engineering
controls.
PPE should only be used as a temporary measure until more effective controls can be implemented. By understanding and applying the hierarchy of controls, workplaces can significantly reduce risks and create a safer environment for everyone.
