Revises workers' compensation coverage for certain injuries to volunteer and professional public safety and law enforcement personnel.

This bill (A 1045) revises New Jersey's workers' compensation law to expand coverage for cardiovascular or cerebrovascular injuries or deaths occurring during emergency response or recovery. It directly affects volunteer and professional public safety personnel, including volunteer emergency management members, career EMTs/paramedics (even in private sector roles), and 9-1-1 dispatchers - expanding coverage beyond current law. The key change creates a rebuttable presumption that such injuries are work-related if they occur while responding to, or within 24 hours of remediating, a defined emergency (like fire suppression, medical rescue, or criminal apprehension). Rebuttal requires clear medical evidence showing work wasn't a substantial cause, or evidence of factors like intoxication or self-infliction. The law applies immediately to all pending cases.
