SAFETY IN THE SHOPA GUIDE TO SAFETY WHILE ARC WELDING

PRESENTATION OUTLINE GENERAL SHOP SAFETY HOUSEKEEPING FIRE PREVENTION MANAGEMENT WELDING SHOP SAFETY EYE PROTECTION DRESS CODE BEHAVIOR VENTILATION

Housekeeping • Cleaning work areas • Sweeping—prevent slips and falls • Keeping designated walking areas clear of debris • Restoring equipment and tools after job is completed

Fire Prevention • Discard frayed cords and wires • Keep flammable liquids away from heat • Class C fire extinguishers for electrical fires

General Management • Safety programs—training, meetings, etc. • Emergency phone numbers • Never Weld near water

Safety: Eye Protection • “An ounce of prevention is worth a pound of cure” when it comes to eye protection • Always wear proper eye protection when working in the shop • A welder must be protected from harmful light radiation given off by the welding process • For welding you will be using chipping goggles and a welding helmet

Here are examples of proper eye protection

Here’s a good example of a welder wearing all the proper welding protection

Proper Attire

Behavior • Most accidents are caused by carelessness • Caused by human error • Refrain from getting involved in poor shop behavior: scuffling playing with tools tripping running pushing hurrying projects disobeying shop rules loud talking

Welding Fumes • Welding fumes can be harmful to the welder causing implications such as: • Irritation of the respiratory tract • Metal fume fever • A condition known as siderosis • Slightly increase the risk of lung cancer • For these reasons, one should take precaution with welding fumes

Welding Fumes • Welding should be done in a well ventilated area • Should attempt to control fumes at the source • Common ways • Extracted benches • Local exhaust ventilation

Common Ventilation Practices Extracted bench method Local exhaust ventilation

Safety Electrical Hazards Fumes and Gases Arc Radiation Fire or Explosion Hazards in the Work Area

Electrical Hazards • High Voltage Can Kill • Do Not Operate With Covers Removed • Disconnect Input Power Before Servicing • Do Not Touch Electrically Live Parts • Electrical Shock Can Kill • Do Not Touch Electrode With Skin or Wet Clothing • Insulate Yourself From Work and Ground

Fumes & Gases • Welding May Produce Hazardous Fumes And Gases • Shielding Gases Can Displace Air and May Cause Injury or Death • Use Ventilation To Keep Air Breathing Zone Clear • Do Not Weld Near Chlorinated Hydrocarbons

Arc Radiation • Electric Arc Welding Rays Can Burn Eyes and Skin • Always Use a Helmet When Arc Welding • Select Appropriate Filter Lens • Wear Appropriate Clothing • Provide Non-Flammable Shielding to Protect Others

Fire or Explosion • Remove Flammable Materials From The Welding Area • Keep a Fire Extinguisher in the Welding Area • Wear Fire Retardant Clothing • Do Not Weld on Containers Which Have Held Combustible Materials

General Work Area Hazards • Keep Power Source Cables, Welding Materials and Tools Neatly Organized • Connect Work Cable as Close as Possible to the Weld Area • Use Only Properly Grounded Equipment • Always Disconnect Power to Arc Welding Equipment Before Servicing
