1. Scope

This procedure covers the safe practices for welding operations, including arc welding, gas welding, and cutting processes. It applies to all welding activities conducted in confined spaces, on platforms, and in general work areas.

This procedure is applicable to all employees and contractors involved in welding operations and should be used in conjunction with other safety procedures related to fire prevention and personal protective equipment (PPE).

2. Definitions

Confined Space
A relatively small or restricted space such as a tank, boiler, pressure vessel, or small compartment of a ship [1].

Welding Cable
Cables used to conduct electricity to the welding machine, which must be placed clear of passageways, ladders, and stairways [2].

Flashback Device
A safety device installed on hoses of an oxygen fuel system to prevent the reverse flow of gases [3].

3. Responsibilities

3.1 Supervisors

• Ensure all welding operations are conducted safely and in compliance with this procedure.
• Verify that all workers are trained and competent in welding safety practices.
• Conduct regular inspections of the work area and equipment.

3.2 Workers

• Follow all safety procedures and use the required PPE.
• Report any unsafe conditions or equipment to the supervisor immediately.
• Ensure proper ventilation is maintained during welding operations.

3.3 Health and Safety Representative

• Monitor compliance with safety standards and procedures.
• Assist in the investigation of incidents related to welding operations.

4. Potential Hazards and Risks

Hazard	Risk	Control Measures
Exposure to harmful fumes	Respiratory issues	Use local exhaust or general ventilation systems [4]
Fire and explosion	Burns, property damage	Remove or protect combustibles, use fire-resistant shields [5]
Electric shock	Injury or fatality	Ensure proper grounding and use of insulated tools [6]

5. Personal Protective Equipment (PPE)

Proper PPE is essential to protect against the hazards of welding.

• Welding Helmet - Protects eyes and face from arc rays and sparks [2].
• Goggles - Protects eyes from flying particles and harmful rays [2].
• Flameproof Gauntlet Gloves - Protects hands from heat and sparks [7].
• Flame-Resistant Clothing - Protects body from heat and sparks [7].
• Ear Protection - Recommended for overhead welding or in confined spaces [1].

Inspect PPE before use and maintain it according to manufacturer instructions.

6. Equipment and Tools

Proper use and maintenance of equipment are crucial for safe welding operations.

• Welding Machine - Ensure it is properly grounded and maintained [6].
• Gas Cylinders - Must be secured upright and stored properly [3].
• Ventilation Equipment - Use to maintain air quality and remove fumes [4].

Inspect equipment regularly and ensure it is in good working condition.

7. Pre-Job Requirements

7.1 Training and Competency

Workers must be trained in welding safety and hold relevant certifications.

7.2 Pre-Job Briefing

Conduct a briefing to discuss the work plan, potential hazards, and emergency procedures.

7.3 Work Area Preparation

Ensure the area is free of combustibles and properly ventilated. Set up barriers to protect others from welding rays [7].

8. Safe Work Procedure Steps

Step 1: Preparation

• Inspect all equipment and PPE.
• Set up ventilation and barriers.
• Secure gas cylinders and check connections.

Step 2: Welding Operations

• Follow the welding plan and maintain a safe distance from combustibles.
• Use proper techniques to minimize exposure to fumes and sparks.

Step 3: Post-Welding

• Disconnect equipment and secure the area.
• Inspect the work area for any signs of fire or hazards.

9. Precautions and Safety Measures

• Ensure proper ventilation to prevent fume accumulation.
• Use fire-resistant barriers to protect against sparks.
• Maintain a clean work area to prevent tripping hazards.

10. Emergency Procedures

10.1 General Emergency Response

• Evacuate the area and alert emergency services in case of fire or explosion.

10.2 Specific Emergency Scenarios

• Fire - Use appropriate fire extinguishers and follow fire response protocols.
• Gas Leak - Shut off gas supply and ventilate the area.

10.3 Emergency Contact Information

11. Incident Reporting and Investigation

Report all incidents and near-misses to the supervisor immediately. Conduct investigations to identify root causes and implement corrective actions.
