AWS Certified Welding Inspector — FundamentalsSafetyMedium
A welding inspector is reviewing the fire prevention plan for a fabrication shop. The plan states that fire extinguishers should be located within 50 feet of any welding operation. According to common welding safety standards (e.g., ANSI Z49.1), what is the MINIMUM acceptable distance for a suitable fire extinguisher from hot work operations?
- A10 feet (3 meters).
- B50 feet (15 meters).
- C20 feet (6 meters).
- D35 feet (10 meters).
Show answer & explanationAnswer & explanation
Correct answer: D. 35 feet (10 meters).
ANSI Z49.1, 'Safety in Welding, Cutting, and Allied Processes,' specifies that fire extinguishing equipment, such as extinguishers, should be readily available and located within 35 feet (10 meters) of hot work operations. Fifty feet is acceptable, but 35 feet is the minimum standard.
Why the other options are wrong
- A. 10 feet is generally too close and might place the extinguisher within the immediate hazard zone.
- B. 50 feet is acceptable, but the question asks for the MINIMUM acceptable distance, which is 35 feet.
- C. 20 feet is closer to ideal but not the minimum distance specified by common standards.
Hot Work Fire Extinguisher Distance
The minimum distance fire extinguishing equipment must be located from hot work operations to ensure immediate access in case of fire.
- ANSI Z49.1 standard applies.
- Minimum distance is 35 feet (10 meters).
- Ensures quick access for fire control.
Memory trick: Thirty-five feet, not too far, not too near, keeps the fire from spreading, have no fear.
