Welding Safety SECTION OVERVIEW: The next few slides identify safety requirements when welding. TEACHER NOTES: Slides 15-27: Bulleted information on topical areas is provided to lead class discussion on important areas of safety in the welding environment. Use this time to discuss OSHA (Occupational Safety & Health Administration) OSHA - www.osha.gov Regulation 1910 – Occupational Safety and Health Standards for general industry Tell the students where all the information listed on the following slides can be found. MSDS – www.lincolnelectric.com Quick Links: MSDS or call 1-216-481-8100 See slide 20 for additional website links See Facilitator’s Guide for more information on welding hazards such as Fumes and Gases and Electrical Shock. For a free DVD on Welding Safely, submit the order form found in the back of the Lesson Plan Facilitator’s Guide (shipping and handling charges will apply).

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 Z49.1) Lincoln Electric’s ‘Arc Welding Safety’ (E205)

Understand and follow all warning labels found: On welding equipment With all consumable packaging Within instruction manuals

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/products/msds/ front

Protect yourself and others from potential hazards including: 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

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

Do not make repairs yourself, alert your instructor immediately! 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!

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

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

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

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 fire-proof pants Welding cap, helmet and safety glasses Ear protection – ear plugs and muffs

Welder Responsibilities SECTION OVERVIEW: The next few slides reference information extracted from the ‘Guide for the Training and Qualification of Welding Personnel, Entry Level Welder’ (AWS EG 2.0) booklet to help students understand about the responsibilities of a welder. TEACHER NOTES: Slides 49-55: These slides include bulleted information on topical areas to lead class discussion on the importance of each area when conducting the welding processes. ‘Guide for the Training and Qualification of Welding Personnel, Entry Level Welder’ (AWS EG 2.0) book available through the AWS. (www.aws.org) For more information on Lincoln Electric's Welding Educator’s Workshop see the Technical Training Guide (ED122): http://content.lincolnelectric.com/pdfs/products/literature/2006ed122.pdf

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

A welder MUST always follow safe work practices: 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 Z49.1) Lincoln Electric’s ‘Arc Welding Safety’ (E205)

Welding can teach you about…. 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?

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.

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

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
