AK SB103

Establishes a presumption of compensability for firefighters with respiratory disease, cardiovascular events within 72 hours of exposure to smoke/fumes/toxins, and eight specified cancers (brain, melanoma, leukemia, non-Hodgkin's lymphoma, bladder, ureter, kidney, and prostate).

Requires firefighters to have served at least seven years in the state and received a qualifying medical examination upon hire and annual exams during the first seven years showing no evidence of the disease.

Limits the presumption to three calendar months per year of service following termination, with a maximum extension of 60 calendar months after the last date of employment.

Provides a grandfather provision for firefighters who entered service before August 19, 2008, allowing them to claim the presumption if they received all available department medical exams during their first seven years showing no disease evidence.

Applies the presumption only to claims made on or after the effective date of the act.
