By following these frameworks, organizations can implement effective controls, enhancing safety and compliance across various industries.

3.2. Quantitative vs. Qualitative Risk Assessment

Quantitative risk assessment uses numerical data to evaluate probabilities and impacts, while qualitative assessment relies on descriptive methods like expert opinions. Both approaches are vital, with quantitative providing precise metrics and qualitative offering scenario-based insights. Tools like fault tree analysis support quantitative methods, whereas HACCP aligns with qualitative frameworks. Together, they ensure comprehensive risk evaluation, enhancing decision-making in safety management.

3.3. Prioritizing Hazards Based on Severity and Likelihood

Prioritizing hazards involves evaluating their potential impact and probability of occurrence. High-severity, high-likelihood hazards demand immediate attention, while low-severity, low-likelihood risks may require less urgent action. This process ensures resources are allocated effectively, focusing on critical threats first. Tools like risk matrices or HACCP systems help organizations systematically rank hazards, enabling proactive safety measures to mitigate potential dangers.

Control Measures and Mitigation Strategies

Effective control measures include engineering solutions, administrative protocols, and PPE, ensuring hazard mitigation and compliance with safety standards like OSHA and HACCP guidelines.
