Demonstrating safe practices should include

• wearing appropriate PPE
• explaining and guarding against hazards (e.g., electrical, heat, light, fumes)
• discussing and implementing the proper methods for ventilating the welding area
• explaining SDS literature
• explaining and demonstrating the proper procedures for SMAW operations.

Process/Skill Questions:

• What are the hazards associated with SMAW operations? What PPE would address each of these hazards, and how?
• What is the purpose of a welding helmet?
• What shade lenses should be used for arc welding up to the 250-amp rating?
• What is meant by the term flash in welding?
• Why should synthetic fibers not be worn while welding?
• Why is it important to remove flammable materials and fumes from the work area?
