Once hazards are identified, the next step is to assess the risks associated with them. This involves evaluating:

• Likelihood: Determining the probability of the hazard occurring.
• Severity: Assessing the potential impact or harm that the hazard could cause.
• Exposure: Considering the frequency and duration of exposure to the hazard.

3. Risk Control Measures

After assessing the risks, the next step is to implement control measures to mitigate or eliminate them. These measures can be categorized into:

• Engineering Controls: Using physical modifications or equipment to reduce hazards, such as installing safety guards or ventilation systems.
• Administrative Controls: Implementing policies, procedures, and training programs to reduce risks, such as safety protocols or regular inspections.
• Personal Protective Equipment (PPE): Providing and requiring the use of PPE, such as helmets, gloves, or respirators, to protect individuals from hazards.

4. Monitoring and Review

Risk management is an ongoing process that involves regular monitoring and review. This includes:

• Regular Inspections: Conducting periodic inspections to ensure that control measures are effective and hazards are under control.
• Incident Reporting: Encouraging the reporting of accidents, near-misses, and safety concerns to identify areas for improvement.
• Continuous Improvement: Updating risk management practices based on feedback, new information, and advancements in safety technology.

Case Studies of Hazardous Activities
