AZ HB2410

Amends Arizona workers' compensation law to create a presumption that heart-related, perivascular, or pulmonary injuries or deaths of firefighters are occupational diseases arising from employment.

Presumption applies if firefighter passed pre-employment physical without evidence of heart-related or pulmonary illness, received physical examination aligned with NFPA 1582 standards, was exposed to a known event, and injury or death occurred within 24 hours of exposure and was reasonably related to it.

Presumption may be rebutted by evidence of a specific non-employment cause of the injury or illness by a preponderance of the evidence.

Presumption does not apply if firefighter's exposure to cigarettes or tobacco products outside official duties is a substantial contributing cause of the heart-related, perivascular, or pulmonary condition.

Defines "firefighter" to include both paid firefighters and volunteer firefighters as described in section 23-901 of Arizona Revised Statutes.
