Assessment Date: [DATE]
Assessor: [ASSESSOR NAME]
Department/Area: [DEPARTMENT/AREA]
Review Date: [REVIEW DATE]
1. Assessment Scope
This risk assessment covers all rigging and hoisting operations performed by elevator trade personnel. It includes the selection, inspection, and use of rigging equipment, as well as the hoisting and lowering of materials and equipment. The scope excludes elevator installation, which is covered under a separate risk assessment.
2. Risk Assessment Methodology
This risk assessment uses a 5x5 risk matrix to determine risk levels. The hierarchy of controls is applied to mitigate identified hazards, prioritizing elimination and substitution where feasible, followed by engineering controls, administrative controls, and finally, personal protective equipment (PPE).
3. Risk Matrix Reference
The following matrix is used to evaluate risk levels based on likelihood and severity:
Likelihood | ||||||
---|---|---|---|---|---|---|
Rare | Unlikely | Possible | Likely | Almost Certain | ||
Severity | Catastrophic | Low | Low | Medium | Medium | High |
Major | Low | Medium | Medium | High | High | |
Moderate | Medium | Medium | High | High | Extreme | |
Minor | Medium | High | High | Extreme | Extreme | |
Negligible | High | High | Extreme | Extreme | Extreme |
4. Hazard Identification and Risk Evaluation
