Presentation Transcript

  1. Welding, Cutting, and Brazing

  2. Welding safety program guidelines • Determine who is accountable for enforcement of welding operations • Hot work permitting system • Perform a job hazard assessment of welding equipment 1a

  3. Welding safety program guidelines • Special procedures for equipment used in welding process • Care of cylinders • Ventilation systems • Fire prevention 1b

  4. Welding safety program guidelines • Engineering controls • Administrative controls • Personal protective equipment • Equipment inspection and maintenance • Incident investigation 1c

  5. Welding hazards • Damage to eyes and skin • Ultraviolet (UV) rays • Infrared rays • Purging and cleaning of closed containers prior to welding operations 2a

  6. Welding hazards • Toxic gases, fumes, and dusts • Fire hazards from welding and cutting operations 2b

  7. Welding hazards • Metal splatter • Electric shock • Explosion hazards 2c

  8. General safe work practices • Use a platform with toeboards when working from elevated surfaces • Protect workers from stray sparks or slag in areas below elevated work surfaces 3a

  9. General safe work practices • Warn others of hot metal by marking work areas • Keep floor areas clear of electrodes and/or electrode stubs 3b

  10. General safe work practices • Never use bare conductors, damaged regulators, torches, or electrode holders • Never arc weld or resist weld while standing on damp surfaces 3c

  11. General safe work practices • Keep fire extinguishers near areas where hot work is performed 3d

  12. Compressed gas cylinder handling and storage • Never accept compressed gas cylinders (CGCs) that were shipped in a horizontal position • Store CGCs upright • Keep CGCs secured with chains or cables 4a

  13. Compressed gas cylinder handling and storage • Group cylinders by type of gas • Store full and empty cylinders apart • Store gases so that old stock is removed and used first 4b

  14. Compressed gas cylinder handling and storage • Keep protective caps on stored CGCs • Prevent the dropping or banging of CGCs • Don’t roll CGCs along the bottom rim 4c

  15. Compressed gas cylinder handling and storage • Don’t lift CGCs by the cap unless using hand trucks designed for this purpose • Prevent cylinders from falling, or from having objects fall on them 4d

  16. Compressed gas cylinder handling and storage • Ensure that valves, hoses, connectors, and regulators are in good condition 4e

  17. Compressed gas cylinder handling and storage • Never open valves until regulators are drained of gas and pressure adjusting devices are released • When empty, close and return CGCs to the vendor 4f

  18. Compressed gas cylinder handling and storage • Empty CGCs must be labeled “MT” or “Empty” • Keep oil and grease away from oxygen CGCs, valves, and hoses 4g

  19. Fire watches for welding operations 5a

  20. Designate a fire watch whenever these conditions exist • Combustible material is within 35 feet of the point of operation • Combustibles are more than 35 feet away, but are easily ignited by sparks 5b

  21. Designate a fire watch whenever these conditions exist • Wall or floor openings within a 35-foot radius expose combustible material in adjacent areas • Combustible materials opposite of walls or ceilings can be ignited by conduction or radiation 5c

  22. Fire watchers will: • Have fire extinguishers readily available, and be trained in their use • Be familiar with alarm systems and their operation in the event of a fire 5d

  23. Fire watchers will: • Watch for fires in all exposed areas • Only try to extinguish fires obviously within the capacity of the equipment 5e

  24. Fire watchers will: • Stay in hot work areas for at least one half hour after hot work operations have ceased to detect and extinguish smoldering fires 5f

  25. Welding safety in confined spaces • Before entry, test the work space for the following types of hazards: • Flammability • Combustibility • Toxic fumes • Slippery floor surfaces 6a

  26. Welding safety in confined spaces • When and where applicable, wear respiratory protection and a safety harness attached to a lifeline 6b

  27. When hot work in a confined space is interrupted • Disconnect power to arc welding or cutting equipment • Remove electrodes from holders • Turn off torch valves 6c

  28. When hot work in a confined space is interrupted • Turn off gas supply to gas welding and cutting units at a point outside the space • Remove the torch and hose from the confined space, if possible 6d

  29. Make housekeeping a priority • Keep welding areas free of combustibles • Ensure proper storage of compressed gas cylinders 7

  30. Don’t take shortcuts • Getting the job done safely is the first consideration • Always evaluate the job and implement appropriate safety precautions 8
