The Hierarchy of Controls in Practice
The IP Lead can use the Hierarchy of Controls to help and support the IPC work. Examples of the controls are as follows
Elimination and substitution are best used in the design or development of a process as they can be difficult and expensive actions to adapt into an existing process. A good opportunity to use elimination and substitution is when selecting new equipment or designing new procedures.
Elimination removes the hazard at the source. It is the first solution to protect employees by removing exposure to any risk and often involves changing the work processes i.e., doing the job in a different way.
Substitution is replacing the source of the hazard for a safer option. A risk assessment of the substitute is required in order to ensure it is not more hazardous than the original and that it fits in with other agents in the workplace. Effective substitutes reduce the potential for harmful effects and do not create new risks.
Engineering controls reduce or prevent exposure and include modifying equipment or the workspace, using protective barriers and ventilation, etc. The most effective engineering controls
Are part of the original equipment design
Remove or block the hazard at the source preventing contact with residents or employees
Operate correctly without interfering with the work process or making the work process more difficult
Prevent modifying or interfering with the control
Need minimal user input for the controls to work
Engineering controls can be expensive but long-term operating costs tend to be lower, especially when protecting multiple workers. They can save money in other areas of the work process or facility operation.
Administrative controls establish work practices that reduce the duration, frequency, or intensity of exposure to hazards and may include
Education and training
Job rotation
Ensuring adequate rest breaks
Limiting access to hazardous areas or machinery
PPE refers to various barriers worn alone or in combination to protect residents, employees and visitors from hazardous substances, e.g. blood and body fluids, chemicals, infections organisms, etc. A PPE programme should consider
Workplace hazards assessment
Selection and use of PPE
Inspection and replacement of damaged or worn-out PPE
Employee training
Monitoring for continued effectiveness
It’s important not to rely on PPE alone to control hazards when other effective control options are available. PPE will be effective only when used correctly and consistently.
