Your job site has a temporary wood frame structure under construction. What is the minimum required fire extinguisher rating for this type of construction?
Correct Answer
A) 2A rating within 75 feet of travel
OSHA requires a minimum 2A rated fire extinguisher within 75 feet of travel distance for wood frame construction. This provides adequate coverage for Class A fires involving ordinary combustibles.
Why This Is the Correct Answer
OSHA 29 CFR 1926.150(c)(1)(i) specifically requires a minimum 2A rated fire extinguisher within 75 feet of travel distance for temporary wood frame construction. The 2A rating is adequate for Class A fires involving ordinary combustible materials like wood, paper, and fabric commonly found in wood frame construction. The 75-foot travel distance ensures workers can quickly access fire suppression equipment when needed, balancing safety requirements with practical job site logistics.
Why the Other Options Are Wrong
Option C: 2A rating within 100 feet of travel
While this option correctly identifies the 2A rating requirement, it incorrectly states the travel distance as 100 feet. OSHA specifically limits the travel distance to 75 feet maximum for temporary wood frame construction. The extended 100-foot distance could delay emergency response and violates the regulatory requirement.
Option D: 10A rating within 50 feet of travel
This option incorrectly specifies a 4A rating and 100-foot travel distance. OSHA requires only a 2A rating for wood frame construction, and the travel distance must not exceed 75 feet. The 4A rating would be excessive for this application and the 100-foot distance violates OSHA's maximum travel distance requirement for temporary wood frame structures.
Memory Technique
Remember '2A-75' for wood frame: 'Two A's for wood, Seventy-Five feet good' - the minimum fire protection standard for temporary wood construction.
