Assessment Date: [DATE]
Assessor: [ASSESSOR NAME]
Department/Area: [DEPARTMENT/AREA]
Review Date: [REVIEW DATE]
1. Assessment Scope
This Job Hazard Analysis (JHA) covers the welding of stainless steel, including all related tasks such as material handling, preparation, welding, and post-weld cleaning. The scope includes all personnel involved in the welding process. Excluded are non-welding activities in the same area.
2. Risk Assessment Methodology
This risk assessment uses a 5x5 risk matrix to determine risk ratings based on likelihood and severity. The hierarchy of controls (Elimination, Substitution, Engineering controls, Administrative controls, and PPE) is applied to mitigate identified hazards. The JHA process involves identifying job steps, hazards, and control measures. [1]
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 |
