Legislative findings-1987 c 515: "The legislature finds that the employment of firefighters exposes them to smoke, fumes, and toxic or chemical substances. The legislature recognizes that firefighters as a class have a higher rate of respiratory disease than the general public. The legislature therefore finds that respiratory disease should be presumed to be occupationally related for industrial insurance purposes for firefighters." [ 1987 c 515 s 1.]
