    2. Arc Welding Fusion process for joining metals An electric arc from a AC or DC power source supplies intense heat to join the base material and an electrode

    3. Arc Welding Components

    4. Safety Concerns Electrocution Fires/Explosions Burns Arc Eye Proper use of equipment Bystanders Toxic Fumes Arc Radiation High Noise Level Safe and Clean Working Environment

    5. Statistics Nine cases were investigated by OSHA between 1991-2004 involving arc welding accidents Of these cases, electrocution and fires/explosions were the ending results of arc welding mishaps

    6. Statistics

    7. OSHA Regulations 1926.351 Only use electrode holders specifically designed to safely handle the maximum rated current required. When electrode holders are unattended, the electrodes shall be removed and the holders placed or protected that they cannot make electrical contact with employees or conducting objects.

    8. OSHA Regulations 1926.351 All welding cables should be well insulated and repairs or splices must be at least 10ft from the electrode. Splices made closer must have the same insulating quality as the cable.

    9. OSHA Regulations 1926.351 Cable in need of repair CANNOT be used

    10. OSHA Regulations 1926.351 Pipelines carrying flammable gases, liquids, or electric wires shall NOT be used as a ground Pipelines uses as a ground must maintain electrical contact at all joints which must be bonded and periodically inspected for electrolysis or fire hazard

    11. OSHA Regulations 1926.351 Arc welding machine frames must be ground and the ground must be able to break fuse When left unattended, remove electrodes and place away from conductive materials When left unattended or when moving turn the machine OFF

    12. Safe Work Practices Wear PPE Proper personal protection equipment shall be worn during the entire welding process to prevent hazards from the intense rays and sparks. Clothing shall be dry and free of holes

    13. Safe Work Practices Ventilate and Exhaust Work in a well ventilated location Keep your face away from the welding to avoid particulates, toxic fumes and flames Use electrodes that produces less fumes if possible Use a qualified observer and gas level monitor when working in confined spaces

    14. Safe Work Practices Electric Shock Precautions Do not weld near flammable material Do not touch live circuits Insure that gloves are well insulated and clothing is dry Work on a insulating mat and wear rubber sole shoes Avoid welding in moist surroundings and weather

    15. Safe Work Practices Equipment Precautions Inspect equipment before use Know and follow proper operating procedures Inspect equipment before use Work at recommended voltages Turn off equipment when not in use

    16. Safe Work Practices Good Housekeeping Shield others from the welding area Work in a clean, clutter free environment Secure electrode and work cables together. Keep them out of traffics way Never put yourself between the electrode and work cable
