Welding Safety 1

Arc Welding Safety • Welding can be safe when sufficient measures are taken to protect yourself and others from potential hazards • Students should read and understand the following before welding: – Warning Labels – Material Safety Data Sheets (MSDS) • Students should also be familiar with the following information – ‘Safety in Welding, Cutting, and Allied Processes’ (ANSI Z 49. 1) – Lincoln Electric’s ‘Arc Welding Safety’ (E 205) 2

Warning Labels • Understand follow all warning labels found: – On welding equipment – With all consumable packaging – Within instruction manuals 3

Material Safety Data Sheets • Material Safety Data Sheets (MSDS) are: – Required by law and OSHA – Created by the manufacturer of a product per OSHA guidelines – Designed to inform users – Shipped with every box of Lincoln Electric consumable product – Available free online at: www. lincolnelectric. com/product s/msds/ front 4

MSDS - Continued • MSDS outlines a product’s: § Identity and composition § Potential hazards § Safe use § Handling information § Manufacturer contact information back 5

ANSI Z 49. 1 • ANSI Z 49. 1: Safety in Welding, Cutting, and Allied Processes – A safety document published by the American Welding Society that covers safe practices in the welding environment – To get your free copy, go to: § www. aws. org/technical/facts/Z 49. 1 -2005 -all. pdf • E 205: Arc Welding Safety – A safety document summarizing many of the hazards and safe practices for welding – Download and print your own copy at: § http: //content. lincolnelectric. com/pdfs/products/literature/e 205. pdf – Free copies available from Lincoln Electric at: § www. lincolnelectric. com/products/litrequest • Access the E-learning Site @ www. agedlearning. com 6

Arc Welding Safety • Protect yourself and others from potential hazards including: – – Fumes and Gases Electric Shock Arc Rays Fire and Explosion Hazards – Noise – Hot objects 7

Fumes and Gases • Fumes and gases can be hazardous to your health • Keep your head out of the fumes • Use enough ventilation, exhaust at the arc, or both, to keep fumes and gases from your breathing zone and the general area • See product labeling and MSDS for ventilation and respirator requirements 8

Electric Shock • Electric shock can kill • Do not touch live electrical parts – Primary Voltage – 230, 460 volt input power – Secondary Voltage – 6 to 100 volts for welding • Insulate yourself from work and ground • Follow all warnings on welding equipment Do not make repairs yourself, alert your instructor immediately! 9

Arc Rays • Arc rays can injure eyes and burn skin • The welding arc is brighter than the sun • Precaution must be taken to protect your eyes and skin from UV radiation • Wear correct eye and body protection 10

Fire and Explosion Hazards • Welding sparks can cause fires and explosions • Sparks and spatter from the welding arc can spray up to 35 feet from your work • Flammable materials should be removed from the welding area or shielded from sparks and spatter • Have a fire extinguisher ready • Inspect area for fires 30 minutes after welding 11

Noise • Loud noises can damage your hearing • Keep loud noises at a safe level by using proper hearing protection such as: – Ear plugs – Ear muffs 12

Protective Clothing Welders must wear protective clothing for – Protection from sparks, spatter and UV radiation – Insulation from electric shock • Protective clothing includes … – Fire-proof clothing without rolled sleeves, cuffs or frays – Work boots – Welding gloves, jackets, bibs, and fireproof pants – Welding cap, helmet and safety glasses – Ear protection – ear plugs and muffs 13

Welder Responsibilities 14

What are the Responsibilities of a Welder? • Welders have many areas of important responsibilities • These relate to: – – – Arc Welding Safety Knowledge – Content Attitude – Reactions Skills – Performance Work Habits – Daily Functions Always keep safety in mind when welding 15

Arc Welding Safety • A welder MUST always follow safe work practices: – Students should read and understand the following before welding: § Warning Labels § Material Safety Data Sheets (MSDS) – Students should also be familiar with the following information § ‘Safety in Welding, Cutting, and Allied Processes’ (ANSI Z 49. 1) § Lincoln Electric’s ‘Arc Welding Safety’ (E 205) 16

Knowledge - Content • Welding can teach you about…. – Science when applying metallurgy, chemistry, electricity, etc. – Math when calculating angles, joint design, and weld size – English when communicating and interpreting drawings, codes, and procedures – Technical areas when performing the actual welding applications How much science and math went into the development of this bike? 17

Attitude • The best welders demonstrate a can-do attitude when performing welding processes • This means being able to… – – – Work as a team member Communicate ideas to others Listen to opinions of others Promote a positive attitude Provide solutions to problems Take pride in workmanship These welders work together to inspect a weld. 18

Skills/Performance • A welder must demonstrate technical skills when performing welding processes • A welder must know how to: – Use hand tools and materials, to operate equipment in a safe, accurate, and consistent manner – Acquire and evaluate information needed for problem solving – Complete quality work – Maintain equipment There is no room for poor workmanship in NASCAR 19

Work Habits/Daily Functions • A welder must practice good working habits when performing welding processes • This means being able to … – Follow detailed verbal and written instructions – Maintain workspace, equipment, and tool cleanliness – Correctly fill out, maintain and submit time cards, work assignment cards, and other records as required – Follow safe working practices Agriculture teachers brush up on their welding skills at Lincoln Electric’s Welding Educator’s Workshop 20
