Q

NFPA 1582

A

Standard on Comprehensive Occupational Medical Program for Fire Departments
This Standard outlines an occupational medical program that will reduce risks and provide for the health, safety, and effectiveness of fire fighters operating to protect civilian life and property.
It contains a concise list of requirements for medical testing and physical examinations that should be done when firefighters join the department, and each year thereafter. The list includes items such as: a physical examination, chest x-ray, and cancer screening.
