1. Elimination: The most effective control measure is to eliminate the hazard altogether. This can be done by substituting the hazardous agent with a safer alternative, or by redesigning the work process to remove the hazard.
2. Substitution: If elimination is not possible, the next best option is to substitute the hazardous agent with a less harmful one. This could involve using a less toxic chemical, or replacing a noisy machine with a quieter one.
3. Engineering controls: These are physical changes to the work environment that help to reduce exposure to the hazard. Examples include installing ventilation systems to remove airborne contaminants, or using noise barriers to reduce noise levels.
4. Administrative controls: These are changes to work practices or policies that help to minimize exposure to the hazard. This could involve rotating workers to different tasks to reduce their exposure, or implementing strict cleaning procedures to prevent the spread of infectious agents.
5. Personal protective equipment (PPE): PPE should be used as a last resort when all other control measures have been exhausted. This includes items such as gloves, masks, goggles, and earplugs that help to protect workers from exposure to hazardous agents.
By following this hierarchy of control measures, employers can effectively minimize the risk of exposure to agents that pose a threat to workers' health.
