  3. Introduction ● Goal ● Objective ● Hazards ● Summary ● Conclusion Subpart J – Welding Hazards The Goal of this course is to help reduce exposures to welding injuries and illnesses of the jobsite.

  4. Introduction ● Goal ● Objective ● Hazards ● Summary ● Conclusion Subpart J – Welding Hazards The objective of this course is to be able to identify six (6) hazards that are associated with welding operations on the jobsite.

  5. Introduction ● Goal ● Objective ● Hazards ● Summary ● Conclusion Subpart J – Welding Hazards Plasterers do not do welding. So why should I worry? Well…

  6. Introduction ● Goal ● Objective ● Hazards ● Summary ● Conclusion Subpart J – Welding Hazards Don’t look up!

  7. Introduction ● Goal ● Objective ● Hazards ● Summary ● Conclusion Subpart J – Welding Hazards Welding hazards can be anywhere on the jobsite. The following will help you identify six of these hazards and how they can affect your health and safety.

  8. Introduction ● Goal ● Objective ● Hazards ● Summary ● Conclusion Subpart J – Welding Hazards 1. Flash Burn – inflammation of the cornea caused by exposure to the strong ultraviolet light of a welding arc.

  9. Introduction ● Goal ● Objective ● Hazards ● Summary ● Conclusion Subpart J – Welding Hazards 1. Flash Burn – 1926.351(e)Shielding. Whenever practicable, all arc welding and cutting operations shall be shielded by noncombustible or flameproof screens which will protect employees and other persons working in the vicinity from the direct rays of the arc.

  10. Introduction ● Goal ● Objective ● Hazards ● Summary ● Conclusion Subpart J – Welding Hazards 2. Struck By– Cylinders can be knocked over, dislodging the regulator and fly like a rocket, striking anything in its path.

  11. Introduction ● Goal ● Objective ● Hazards ● Summary ● Conclusion Subpart J – Welding Hazards 2. Struck By– 1926.350(a)(9)Compressed gas cylinders shall be secured in an upright position at all times except, if necessary, for short periods of time while cylinders are actually being hoisted or carried.

  12. Introduction ● Goal ● Objective ● Hazards ● Summary ● Conclusion Subpart J – Welding Hazards 3. Burns/Fire – Welding operations produce sparks. These sparks can: drop to lower levels through floor openings, penetrate the other side of a wall, or fly across a room.

  13. Introduction ● Goal ● Objective ● Hazards ● Summary ● Conclusion Subpart J – Welding Hazards 3. Burns/Fire – 1926.352(f)When welding, cutting, or heating is performed on walls, floors, and ceilings, since direct penetration of sparks or heat transfer may introduce a fire hazard to an adjacent area, the same precautions shall be taken on the opposite side as are taken on the side on which the welding is being performed.

  14. Introduction ● Goal ● Objective ● Hazards ● Summary ● Conclusion Subpart J – Welding Hazards 4. Explosion – Welding operations can initiate a volatile reaction with chemicals or dust in the air.

  15. Introduction ● Goal ● Objective ● Hazards ● Summary ● Conclusion Subpart J – Welding Hazards 4. Explosion – 1926.352(c)No welding, cutting, or heating shall be done where the application of flammable paints, or the presence of other flammable compounds, or heavy dust concentrations creates a hazard.

  16. Introduction ● Goal ● Objective ● Hazards ● Summary ● Conclusion Subpart J – Welding Hazards 5. Fumes/Asphyxiation – Welding operations can produce noxious fumes that can make you fell sick quickly, have a latten affect after years of exposure or displace the oxygen in a room.

  17. Introduction ● Goal ● Objective ● Hazards ● Summary ● Conclusion Subpart J – Welding Hazards 5. Fumes/Asphyxiation - 1926.353(a)(1) Mechanical ventilation shall consist of either general mechanical ventilation systems or local exhaust systems.- 1926.353(a)(5)All air replacing that withdrawn shall be clean and respirable.

  18. Introduction ● Goal ● Objective ● Hazards ● Summary ● Conclusion Subpart J – Welding Hazards 6. Radiation - Inert-gas metal arc welding can produce radiation. Besides flash burn, the skin must be protected as well.

  19. Introduction ● Goal ● Objective ● Hazards ● Summary ● Conclusion Subpart J – Welding Hazards 6. Radiation - 1926.353(d)(1)(iii)Welders and other employees who are exposed to radiation shall be suitably protected so that the skin is covered completely to prevent burns and other damage by ultraviolet rays. Welding helmets and hand shields shall be free of leaks and openings, and free of highly reflective surfaces.

  20. Introduction ● Goal ● Objective ● Hazards ● Summary ● Conclusion Subpart J – Welding Hazards When you walk on a jobsite, you should know, there are at least six ways welding operations can affect your health and safety:

  21. Introduction ● Goal ● Objective ● Hazards ● Summary ● Conclusion Subpart J – Welding Hazards 1. Flash Burn2. Struck By3. Burns/Fire4. Explosion5. Fumes/Asphyxiation6. Radiation

  22. Introduction ● Goal ● Objective ● Hazards ● Summary ● Conclusion Subpart J – Welding Hazards Although plasterers do not do welding, there are many hazards on the jobsite you need to be aware of. Remember, OSHA has welding regulations in Subpart J to protect you.
