Portable ladders approved for fire service use can support up to _____.

Portable ladders that are approved for fire service use are typically designed to handle significant loads due to the nature of the job, which often requires fire personnel to carry equipment and work in challenging environments. The maximum load capacity for these ladders is standardized to ensure they can safely support the weight of firefighters, their gear, and any additional loads encountered during operations.

The correct answer reflects the national standards established for fire service portable ladders, which generally indicate a load capacity of 750 pounds. This rating provides a safety margin that accommodates the weight of a firefighter and their equipment, ensuring that the ladder remains stable and functional in emergency situations. Using ladders that adhere to this standard helps maintain firefighter safety and effectiveness during rescue and firefighting operations.
