  1. Under OSHA 29 CFR 1910.252, what minimum distance must combustible materials be kept from welding operations, or what alternative must be used?

    Answer: 10 feet, or use fire-resistant shields

    OSHA 1910.252 requires combustibles be moved at least 35 feet away or protected by fire-resistant guards/shields.

  2. Which ANSI standard governs the selection, care, and use of respiratory protection equipment used during welding?

    Answer: ANSI Z88.2

    ANSI Z88.2 sets the standard for respiratory protection practices, including those used in welding environments.

  3. A welder notices a small fuel-gas leak at a hose fitting. What is the correct immediate action?

    Answer: Stop work, shut off the gas supply, and ventilate the area before repairing

    Any fuel-gas leak requires immediate shutdown and ventilation to prevent fire or explosion.

  4. What is the maximum oxygen concentration (by volume) at which a space is considered oxygen-enriched and presents an elevated fire hazard?

    Answer: Above 23.5%

    OSHA defines an oxygen-enriched atmosphere as one containing more than 23.5% oxygen by volume.

  5. California's Cal/OSHA Title 8 Section 4848 specifically addresses welding safety. Which authority enforces this regulation in Los Angeles County?

    Answer: Cal/OSHA Division of Occupational Safety and Health

    Cal/OSHA's Division of Occupational Safety and Health enforces Title 8 welding regulations throughout California including Los Angeles.

  6. When welding on metals coated with zinc (galvanized), which primary hazard must be controlled through adequate ventilation or respiratory protection?

    Answer: Metal fume fever from zinc oxide fumes

    Heating galvanized metal releases zinc oxide fumes, which cause metal fume fever if inhaled in sufficient quantities.

  7. According to NFPA 51B, a hot work permit system must include which essential element?

    Answer: A fire watch posted for at least 30 minutes after work ends

    NFPA 51B requires a fire watch maintained for a minimum of 30 minutes after hot work is completed to detect smoldering fires.
