Read the first 7 Safety & Welding Standards flashcards as text

  1. What does the term 'lockout/tagout' (LOTO) refer to in a welding shop context?

    Answer: A procedure to de-energize and secure equipment before maintenance

    LOTO (OSHA 29 CFR 1910.147) is an energy control procedure that de-energizes and physically locks equipment before maintenance to prevent accidental startup.

  2. According to AWS Z49.1, a 'hot work permit' is required when:

    Answer: Performing welding in areas with fire or explosion hazards

    AWS Z49.1 requires a hot work permit before conducting welding or cutting in locations where fire or explosion risks are present.

  3. Which AWS standard governs the qualification of welding procedures and welders for piping and tubing?

    Answer: AWS B2.1

    AWS B2.1 covers the specification for welding procedure and performance qualification applicable to a broad range of base metals including piping.

  4. When storing compressed gas cylinders in a welding area, AWS and OSHA require that oxygen and fuel gas cylinders be separated by at least:

    Answer: 10 feet or a 5-foot fire wall

    OSHA 1910.253 requires oxygen and fuel gas cylinders in storage to be separated by at least 20 feet or by a noncombustible barrier at least 5 feet high with a fire rating of 0.5 hour.

  5. AWS standards classify welding fumes containing hexavalent chromium (Cr VI) as particularly hazardous because Cr VI is:

    Answer: A known human carcinogen

    Hexavalent chromium is classified as a known human carcinogen by IARC and OSHA, requiring strict exposure controls during stainless steel welding.

  6. What is the purpose of a 'fire watch' as defined by AWS Z49.1?

    Answer: Observe the work area during and after welding for ignition sources

    A fire watch person monitors the work area during welding and for at least 30 minutes afterward to detect and extinguish any fires that may start.

  7. Which type of respirator is required when welding on lead-containing base metals in an enclosed space?

    Answer: Supplied-air respirator (SAR) or SCBA

    Lead fume in enclosed spaces can quickly exceed safe levels; a supplied-air respirator or SCBA ensures the welder receives uncontaminated breathing air.
