What is the minimum number of exit routes required for a temporary construction office that will house 35 workers during peak periods?
Correct Answer
A) 2 exit routes
OSHA requires at least 2 exit routes when the building occupancy exceeds 500 people or when the building has more than one story. For smaller occupancies like 35 workers, 2 exits provide adequate egress safety.
Why This Is the Correct Answer
OSHA 29 CFR 1926.95 requires a minimum of 2 exit routes for temporary construction facilities to ensure worker safety during emergencies. This requirement applies regardless of occupancy size for construction sites, as workers need multiple egress options in case one exit becomes blocked. The two-exit minimum provides redundancy and helps prevent bottlenecks during emergency evacuations. Even with only 35 workers, the construction environment's inherent hazards justify the enhanced safety requirement.
Why the Other Options Are Wrong
Option B: 3 exit routes
Four exit routes are excessive for a 35-person temporary facility and would be required only for much larger occupancies or special high-hazard situations.
Option C: 1 exit route
Three exit routes exceed the minimum requirement for a facility housing 35 workers and would be unnecessarily costly for temporary construction offices of this size.
Option D: 4 exit routes
One exit route is insufficient for any construction facility housing workers, as it creates a dangerous single point of failure during emergencies where that exit could become blocked or compromised.
Memory Technique
Think 'Construction = 2 minimum' - construction sites are inherently more dangerous than regular buildings, so they need at least 2 exits no matter how small the occupancy.
