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:

| 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

---

1\. Exposure to welding fumes containing hexavalent chromium and nickel.

Potential Consequences: Respiratory irritation, asthma, lung cancer, and other long-term health effects. [2] [2]

Affected Persons: Welders, nearby workers, and anyone in the vicinity of the welding operation.

Initial Risk Assessment

Control Measures

• Use local exhaust ventilation to remove fumes at the source.
• Provide supplied-air respirators when ventilation is not sufficient.
• Substitute welding rods with lower chromium content if possible.
• Implement a respiratory protection program including fit testing and medical evaluations.
• Ensure proper training on the hazards of welding fumes and the use of control measures.

Residual Risk Assessment

2\. Burns from hot metal and spatter.

Potential Consequences: Skin burns, eye injuries, and fire hazards.

Affected Persons: Welders and nearby workers.

Initial Risk Assessment

Control Measures

• Wear appropriate personal protective equipment (PPE), including welding gloves, a welding helmet with the correct shade lens, fire-resistant clothing, and safety boots.
• Ensure the work area is free of flammable materials.
• Use welding blankets to contain spatter.
• Provide training on burn prevention and first aid.

Residual Risk Assessment

3\. Electric shock.

Potential Consequences: Electrocution, burns, and cardiac arrest.

Affected Persons: Welders and anyone in contact with welding equipment.

Initial Risk Assessment

Control Measures

• Ensure welding equipment is properly grounded.
• Inspect welding cables and equipment for damage before each use.
• Use insulated electrode holders.
• Never weld in wet or damp conditions.
• Provide training on electrical safety and lockout/tagout procedures.

Residual Risk Assessment

4\. Eye injuries from arc radiation (UV, IR, and visible light).

Potential Consequences: Arc eye (photokeratitis), cataracts, and retinal damage.

Affected Persons: Welders and anyone viewing the welding arc.

Initial Risk Assessment

Control Measures

• Use welding helmets with the correct shade lens.
• Use welding screens or curtains to shield others from arc radiation.
• Wear safety glasses with side shields under the welding helmet.
• Ensure proper training on the hazards of arc radiation.

Residual Risk Assessment

5\. Fire hazards from sparks and hot materials.

Potential Consequences: Fire, property damage, and injuries.

Affected Persons: Welders, nearby workers, and anyone in the vicinity.

Initial Risk Assessment

Control Measures

• Keep flammable materials away from the welding area.
• Use fire blankets to protect combustible materials.
• Have a fire extinguisher readily available.
• Inspect the welding area for fire hazards before starting work.
• Provide fire safety training.

Residual Risk Assessment

6\. Slips, trips, and falls due to cluttered work areas and welding cables.

Potential Consequences: Sprains, strains, fractures, and other injuries.

Affected Persons: Welders and anyone in the work area.

Initial Risk Assessment

Control Measures

• Maintain a clean and organized work area.
• Keep welding cables and hoses out of walkways.
• Use cable protectors to prevent tripping hazards.
• Provide good housekeeping practices.
• Ensure adequate lighting.

Residual Risk Assessment

7\. Noise exposure from welding equipment and grinding.

Potential Consequences: Hearing loss and tinnitus.

Affected Persons: Welders and nearby workers.

Initial Risk Assessment

Control Measures

• Provide hearing protection (earplugs or earmuffs).
• Maintain welding equipment to reduce noise levels.
• Conduct noise monitoring to assess exposure levels.
• Implement a hearing conservation program.

Residual Risk Assessment

8\. Ergonomic hazards from awkward postures and repetitive motions.

Potential Consequences: Musculoskeletal disorders (MSDs) such as back pain, carpal tunnel syndrome, and tendonitis.

Affected Persons: Welders.

Initial Risk Assessment

Control Measures

• Use adjustable welding tables and chairs.
• Rotate tasks to reduce repetitive motions.
• Provide training on proper lifting techniques.
• Encourage regular stretching and breaks.
• Design work tasks to minimize awkward postures.

Residual Risk Assessment

5\. General Control Measures

---

• Regular inspection and maintenance of all welding equipment.

Conduct pre-use inspections of welding machines, cables, and safety devices. Repair or replace any damaged equipment immediately.

• Proper storage and handling of compressed gas cylinders.

Store cylinders in a secure, well-ventilated area away from flammable materials. Secure cylinders to prevent tipping. Use appropriate regulators and hoses.

• Use of fire-resistant clothing.

All welders and helpers must wear fire-resistant clothing such as cotton treated with flame retardant or leather.

• Good housekeeping practices.

Keep the work area clean and free of clutter. Properly dispose of waste materials. Clean up spills immediately.

• Lockout/Tagout procedures.

Implement lockout/tagout procedures for any maintenance or repair work on welding equipment.

6\. Emergency Preparedness

---

• In case of fire, activate the fire alarm and evacuate the area. Use a fire extinguisher to put out small fires if it is safe to do so.
• In case of electric shock, immediately turn off the power supply and provide first aid. Call for emergency medical assistance.
• In case of exposure to welding fumes, move to fresh air and seek medical attention if symptoms persist.
• Ensure that first aid kits are readily available and well-stocked.

7\. Training Requirements

---

• Welding Safety Training: Comprehensive training on welding hazards, control measures, and safe work practices.
• Respiratory Protection Training: Training on the proper use, fit testing, and maintenance of respirators.
• Fire Safety Training: Training on fire prevention, fire extinguisher use, and evacuation procedures.
• Electrical Safety Training: Training on electrical hazards, grounding, and lockout/tagout procedures.
• Ergonomics Training: Training on proper lifting techniques, workstation setup, and stretching exercises.

8\. Monitoring and Review

---

Review Frequency: Annually, or after any incident or significant change in the welding process

9\. Special Circumstances

---

• Welding in confined spaces requires additional precautions, including air monitoring, ventilation, and rescue procedures.
• Welding outdoors may be affected by weather conditions such as wind and rain, requiring adjustments to ventilation and PPE.
• Night work requires adequate lighting to ensure visibility and prevent accidents.
