Makes provisions permanent relating to disability due to disease or malfunction of the heart or coronary arteries

This bill makes permanent a provision within the volunteer firefighters' benefit law that covers disabilities caused by heart disease or malfunctioning coronary arteries. By extending the existing temporary coverage, which was set to expire in June 2025, the legislation ensures that volunteer firefighters who suffer these specific health issues remain eligible for benefits indefinitely. The law applies only to injuries that occur after the bill takes effect and does not change the fundamental rules for how these benefits are calculated or awarded.
