House adopts expanded firefighter cancer presumption amid pushback from local fire chiefs and fiscal analysts

The House adopted Senate Bill 184 after several stakeholder amendments that narrowed some covered conditions and clarified how payments from the state cancer trust offset workers' compensation benefits. Sponsors said the bill responds to mounting evidence linking firefighting to elevated cancer risks and eases a difficult evidentiary burden for afflicted firefighters.

Supporters framed the measure as fairness and recognition for firefighters who face long‑term occupational risks. "When a firefighter develops one of these devastating diseases after years of service, we shouldn't place the burden on them to prove the obvious," Representative Carter said on the floor. The bill expands the presumptive list of cancers and adjusts the standard of rebuttal employers must meet to deny a presumption.

Local fire chiefs, municipal associations, and fiscal analysts warned that expanding presumptions would increase workers' compensation liabilities for local governments, many of which are already under fiscal strain. Representatives from the Colorado Fire Chiefs Association and special district associations urged caution and asked for state funding support; proponents responded by adopting amendments to preserve existing offsets and to clarify trust interactions.

The House adopted several technical amendments from stakeholders to clarify offsets with the Colorado Firefighter Cancer Trust and narrowed some conditions after further discussion. Lawmakers debated an amendment that would have required the state to share fiscal responsibility; that amendment failed on the floor. The bill passed as amended and will now proceed to the next processing steps.
