Job Title:71 Arc Welding (RRC)Job Performed By:

Required Personal Protective Equipment: Safety Eyewear, Safety Footwear, Leather Gloves, Hearing Protection, Apron, Welding Bib, Full-face Welding Helmet

GENERAL NOTES: Job Safety Analysis:

StepDescriptionHazardControls

1Set up workpiece on fixturea) Strain/sprain from heavy and/or awkward workpiece--b) Foot injury from dropping workpiece--c) Trip/fall in area around Arc Welding workstation--d) Damage to workpiece from incorrect set-up--e) Hand/finger laceration from edge of workpiece--f) Hand/finger contusion from tool slippage while tightening fixturea) Use mechanical hoist or get assistance from co-worker to set-up/ adjust workpiece--b) Wear recommended footwear. Ensure workpiece is securely clamped to fixture--c) Clean/clear work area/surfaces of unused tools/materials. Remove dust/debris.--d) Workpiece should be clean and secure to fixture--e) Wear recommended gloves when handling workpieces with sharp edges--f) Use correct tool and wear recommended gloves

2Install electrode rod into torchElectric shock/burn from electrode rodEnsure Arc Welding machine power to arc is electrically de-energized when changing electrical rod

3Energize and set Arc Welding Machine amperage/ currenta) Electrical shock/burn from contact with electrode rod holder--b) Damage to workpiece from incorrect amperage/currenta) Ensure welding machine is properly grounded. Welder should be insulated from live electrical parts and dry. Inspect and replace cables, plugs and leads that show any signs of defects. Wear recommended gloves and clothing.--b) Refer to Op Sheet and/or Shop Order for correct amperage/current--

4Turn on gas and set flowa) Damage to workpiece from incorrect gas flow rate--b) Bodily injury from explosion of compressed gas cylinder--a) Consult Op Sheet and/or Shop Order for correct flow rate--b) Practice caution around compressed gas cylinders. Protect gas cylinders from excessive heat, mechanical shocks and arcs. Ensure cylinder is insulated and fastened so it will not fall. Do not use a compressed gas cylinder that appears to be damaged and/or defective.--

5Weld workpiecea) Eye injury from welding flash and/or spatter--b) Burns from welding spatter, UV/infrared radiation and/or electrical contact--c) Inhalation of welding fumes or asphyxiation from displaced oxygen--d) Bodily injury from condition or type of workpiece being welded--e) Electrical shock hazard--f) Hearing loss from chronic exposure to noisy machinery--g) Fire due to combustible material in welding area--h) Hand/finger contact burn from hot electrode roda) Wear welding helmet with proper grade of filter plate. Ensure flash curtains/barriers are used to protect bystanders/observers--b) Wear recommended protective clothing. Ensure any exposed skin is covered during the welding process. Do not wear metal jewelry and clothing with cuffs and/or pockets. Stay a safe distance away from arc--c) Use local exhaust ventilation and a fan to maintain good air circulation--d) Do not weld workpiece unless it is properly cleaned--e) Ensure welding machine is properly grounded. Welder should be insulated from live electrical parts and dry. Do not weld when wet. Inspect and replace cables, plugs and leads that show any signs of defect.--f) Wear hearing protection--g) Remove any combustible material from the immediate welding site. Keep a fire extinguisher readily available.--h) When electrode rod gets too short, stop welding and restart with a new electrode rod. Wear recommended gloves.--

6Complete weldinga) Electrical shock/burn or electrical contact with conducting objects, flammable liquids and/or compressed gas cylinders due to energized electrode rod holderEnsure Arc Welding machine power to arc is electrically de-energized. When not in use electrode rod should be removed from holder and holder should be placed so it cannot make electrical contact with conducting objects, flammable liquids and/or compressed gas cylinders.

7Remove workpiece from fixture and transport to inspectiona) Strain/sprain from heavy and/or awkward workpiece--b) Foot injury from dropping workpiece--c) Trip/fall in area around Arc Welding workstation--d) Hand/finger laceration from edge of workpiece--e) Hand/finger contusion from tool slippagea) Use mechanical hoist or get assistance from co-workers to transport workpiece--b) Wear recommended footwear. Ensure workpiece is securely clamped to fixture--c) Clean/clear work area/surfaces of unused tools/materials. Remove dust/debris regularly--d) Wear recommended gloves when handling workpieces with sharp edges--e) Use correct tool and wear recommended gloves
