Removing qualifiers related to the presumption of occupational disease for heart problems.

SB 6180 removes specific time-based restrictions for presuming heart problems as occupational diseases among firefighters and law enforcement officers. It eliminates the previous requirement that heart issues must occur "within seventy-two hours of smoke exposure or twenty-four hours of strenuous exertion" during duty. This change directly affects firefighters (including private-sector department members with 50+ staff) and law enforcement officers who develop heart conditions during or shortly after work, extending the presumption of occupational disease without those time limits. Other existing provisions, such as the 10-year service requirement for cancer presumptions and tobacco use exclusions, remain unchanged.
