  1. A welder is working overhead and a piece of hot slag falls into their boot. What PPE would have prevented this injury?

    Answer: Boot covers or spats

    Boot covers or spats (leather or FR fabric) wrap around the boot top to prevent hot spatter and slag from entering the boot.

  2. What is the primary purpose of a welding curtain or screen in a shared workspace?

    Answer: To protect bystanders from arc flash and UV radiation

    Welding curtains are made of UV-opaque material specifically to shield nearby workers from harmful arc radiation and flash burns.

  3. According to OSHA 1910.252, when is general ventilation alone considered adequate for arc welding?

    Answer: When base metal coatings are non-toxic and the work area is open

    General ventilation is adequate only when the area is large enough, the room air movement is sufficient, and no toxic coatings or base metals are involved.

  4. Which lens shade is typically recommended for shielded metal arc welding (SMAW) at 200–400 amperes?

    Answer: Shade 12

    AWS recommends shade 12 for SMAW operations in the 200–400 ampere range to provide adequate protection against arc radiation.

  5. What type of glove is most appropriate for TIG (GTAW) welding compared to SMAW?

    Answer: Thinner, more flexible gloves for dexterity and heat sensitivity

    TIG welding requires precise finger control to feed filler rod, so thinner, supple gloves are preferred over the heavy gauntlets used in SMAW.

  6. When should a welder perform a pre-use inspection of their auto-darkening welding helmet (ADWH)?

    Answer: Before each use, checking sensors, reaction time, and lens clarity

    A pre-use inspection ensures sensors are clean, shade darkening activates correctly, and the passive filter plate is undamaged before exposing the welder to arc radiation.

  7. Which condition makes electric shock from welding equipment most dangerous?

    Answer: Wet or damp working conditions

    Moisture dramatically reduces body resistance and increases current flow through the body, making shocks far more likely to be fatal in wet conditions.
