Control of hazards is approached through various tools and elements of a Health and Safety Management System.
To determine the best suited control apply the following process:
- Consult relevant employees and safety personnel during the control selection and recommendation process.
- Determine how the hazard could be controlled, both in the short term and the long term.
- Select the controls as high up in the control hierarchy as practicable.
- Document the recommended control options for the hazards.
- Determine if new hazards would be introduced with the implementation of the controls.
- If new hazards would be introduced with the implementation of the controls, perform another hazard identification and risk assessment and determine risk controls.
"Hierarchy of Controls" is a preferred order in which hazards should be controlled. Consideration should be applied in the order presented:
- Elimination - eliminate the hazards where possible. Where possible discontinue the use of the product/process/machine/chemical.
- Substitution - substitute one process for a safer process or substitute the use of one product for a safer product.
- Isolation - isolate the hazard from the employees. Surround the object/area/process in such a way so it cannot impact a person, i.e. control booth or object/area is controlled from a remote location.
- Engineering Controls - methods built into the design of a workplace, equipment or process to minimize the hazard.
- Administration Controls - safe work procedures, safe work practices, rules, instruction and training and adjusted work processes.
- PPE - should be a last resort as it relies on human compliance, can be unreliable unless monitored
