  1. Which standard governs safe practices for welding, cutting, and allied processes in the United States?

    Answer: ANSI Z49.1

    ANSI Z49.1, 'Safety in Welding, Cutting, and Allied Processes,' is the primary safety standard for the welding industry.

  2. A welder notices that a cable insulation is cracked and the copper conductor is exposed. What is the correct action?

    Answer: Stop work immediately and replace or repair the cable before use

    Exposed conductors present a serious electrocution hazard, and work must stop until the cable is properly repaired or replaced.

  3. What is the primary hazard associated with welding on galvanized steel?

    Answer: Generation of zinc oxide fumes that can cause metal fume fever

    Heating galvanized steel releases zinc oxide fumes, which can cause metal fume fever if inhaled without adequate ventilation or respiratory protection.

  4. Which ventilation method is most effective for controlling welding fumes at the source?

    Answer: Local exhaust ventilation (LEV) positioned near the arc

    Local exhaust ventilation captures fumes at the point of generation before they disperse into the breathing zone.

  5. What does OSHA's lockout/tagout (LOTO) procedure require before a welder performs maintenance on welding equipment?

    Answer: Isolating and de-energizing the equipment and verifying zero energy state before work begins

    LOTO requires physically isolating energy sources, applying locks and tags, and verifying the equipment is de-energized before maintenance.

  6. Welding-grade compressed gas cylinders must be stored in what position to prevent valve damage and tipping hazards?

    Answer: Upright and secured with a chain or strap

    Cylinders must be stored upright and restrained with a chain or strap to prevent tipping, which can shear the valve and cause a dangerous projectile.

  7. What color is the oxygen cylinder and its hose typically color-coded in US welding operations?

    Answer: Green cylinder, green hose

    In the US, oxygen cylinders are typically green and oxygen hoses are green, while acetylene cylinders and hoses are red.
