  1. When should a welding helmet's auto-darkening filter (ADF) be replaced or taken out of service?

    Answer: When the lens is cracked, fogged, or fails to darken consistently

    An ADF that fails to darken, has a cracked lens, or shows inconsistent switching must be removed from service immediately to prevent arc eye injuries.

  2. What is the correct procedure for handling a backfire (flame goes out and pops) on an oxy-fuel torch?

    Answer: Close both valves and let the torch cool before relighting

    After a backfire, close both oxygen and fuel valves immediately, allow cooling, inspect the tip for blockage or damage, then relight following proper procedure.

  3. Which OSHA standard primarily governs welding, cutting, and brazing safety in general industry?

    Answer: 29 CFR 1910.252

    29 CFR 1910.252 is the OSHA standard specifically covering safety requirements for welding, cutting, and brazing in general industry workplaces.

  4. What does the term 'flash burn' or 'arc eye' refer to?

    Answer: UV radiation-induced corneal inflammation from unprotected arc exposure

    Arc eye (photokeratitis) is a painful corneal inflammation caused by UV radiation exposure from welding arcs, similar to a sunburn on the eye surface.

  5. What is the purpose of a welding screen or curtain in a shared work area?

    Answer: To protect nearby workers from arc flash, spatter, and UV radiation

    Welding screens and curtains shield coworkers from arc flash, UV/IR radiation, and spatter without requiring them to wear full welding PPE.

  6. When using an angle grinder near welding operations, which additional hazard must be managed?

    Answer: Grinding sparks igniting nearby combustibles or welding fumes

    Grinding sparks can travel significant distances and ignite combustible materials or concentrated welding fumes, requiring a clear work area and fire watch.

  7. What does SDS (Safety Data Sheet) Section 8 specifically provide for welding consumables?

    Answer: Exposure limits and required engineering controls and PPE

    SDS Section 8 (Exposure Controls/Personal Protection) lists permissible exposure limits (PELs), threshold limit values (TLVs), and required ventilation and PPE for the material.
