Study Notes
Control Measures
Control measures are strategies implemented to prevent or mitigate hazards, reducing the risk of injury or illness. Effective control measures involve:
Hierarchy of Control
A prioritized approach to controlling hazards, in order of effectiveness:
- Elimination: Remove the hazard completely.
- Substitution: Replace the hazard with a less hazardous alternative.
- Engineering Controls: Isolate or reduce the hazard through design or modification.
- Administrative Controls: Implement policies, procedures, and training to minimize exposure.
- Personal Protective Equipment (PPE): Use PPE as a last resort, when other controls are not feasible.
Types of Control Measures
- Physical Controls: Barriers, guards, or enclosures to prevent access to the hazard.
- Procedural Controls: Standard operating procedures (SOPs) to ensure safe work practices.
- Behavioral Controls: Training and education to influence worker behavior and attitudes.
- Technological Controls: Automation, alarms, and sensors to monitor and respond to hazards.
Control Measure Selection
When selecting control measures, consider:
- Effectiveness: The measure's ability to reduce the risk.
- Feasibility: The practicality and cost of implementing the measure.
- Acceptability: The measure's impact on workers, the environment, and the organization.
- Hierarchy of Control: Prioritize measures based on their effectiveness in reducing the risk.
Control Measure Implementation
To ensure successful implementation:
- Involve workers: Encourage worker participation in the selection and implementation of control measures.
- Provide training: Educate workers on the new control measures and their responsibilities.
- Monitor and evaluate: Regularly review the effectiveness of control measures and make adjustments as needed.
Learn about the different types of control measures, including the hierarchy of control, and how to select and implement them effectively to reduce hazards and risks. Understand the importance of worker involvement, training, and monitoring in ensuring successful implementation.
