Welding: Hazards and Control Measures

Tasks Involved in Welding:

Preparing the work area
Setting up welding equipment
Performing the welding operation

Hazards:

1. Fire due to Spark: Sparks from welding can ignite combustible materials.

2. Electrical Shock: Risk of shock from welding equipment.

3. Burn Injury: Hot metal and sparks can cause burns.

4. Fall from Height: Working at height poses a fall risk. (If working on elevated platform)

Control Measures:

Remove Combustible Materials: Ensure all flammable materials are cleared from the work area.
Hot Work Booth: Use a booth with a fire blanket to contain sparks.
Gas Testing: Conduct gas tests before and during the welding process if required.
Fire Watcher: Deploy a fire watcher equipped with a fire extinguisher and running water hose.
Personal Protective Equipment (PPE): Provide specific PPE such as face shields, leather gloves, and aprons.
Authorized Personnel: Ensure only trained and authorized personnel handle electrical operations.
Electrical Safety: Use tools routed through an ELCB and ensure cables are free from damage.
Working Platforms: Provide certified platforms with proper anchoring points.
Equipment Inspection: Regularly inspect and tag all tools and equipment.

Gas Cutting: Hazards and Control Measures

Tasks Involved in Gas Cutting:

Setting up gas cutting equipment
Performing the cutting operation

Hazards:

1. Fire due to Spark: Sparks can cause fire.

2. Flashback Explosion: Flashback can cause explosions.

3. Gas Leak Fires: Leaks from hose joints can ignite.

4. Cylinder Toppling: Gas cylinders may fall over and cause accidents.

Control Measures:

Work Booth: Perform gas cutting inside a proper booth.
Flashback Arrestor: Ensure arrestors are installed.
Hose Integrity: Avoid using damaged hoses.
Leak Testing: Conduct soap solution tests to detect leaks.
Fire Readiness: Have a running water hose and fire extinguisher on standby.
Cylinder Security: Keep cylinders in a trolley, upright, and secured with a chain.

Grinding: Hazards and Control Measures

Tasks Involved in Grinding:

Setting up the grinding machine
Performing the grinding operation

Hazards:

1. Unguarded Machine: Machines without guards pose significant risks.

2. Wheel Detachment: Grinding wheels can detach and cause injuries.

3. Fire from Sparks: Sparks can ignite materials.

4. Inadequate PPE: Lack of proper protective equipment increases injury risk.

Control Measures:

Machine Guards: Ensure grinding machines are properly guarded and inspected before use.
Wheel Fitment: Use appropriately sized wheels and ensure they are fitted correctly.
Grinding Booth: Perform grinding inside a designated booth to contain sparks.
PPE Provision: Provide and enforce the use of face shields, leather gloves, and aprons.
