112.18  Firefighters; special provisions relative to disability.--

(1)  Any condition or impairment of health of any Florida municipal, county, port authority, special tax district, or fire control district firefighter caused by tuberculosis, heart disease, or hypertension resulting in total or partial disability or death shall be presumed to have been accidental and to have been suffered in the line of duty unless the contrary be shown by competent evidence. However, any such firefighter shall have successfully passed a physical examination upon entering into any such service as a firefighter, which examination failed to reveal any evidence of any such condition. Such presumption shall not apply to benefits payable under or granted in a policy of life insurance or disability insurance, unless the insurer and insured have negotiated for such additional benefits to be included in the policy contract.

(2)  This section shall be construed to authorize the above governmental entities to negotiate policy contracts for life and disability insurance to include accidental death benefits or double indemnity coverage which shall include the presumption that any condition or impairment of health of any firefighter caused by tuberculosis, heart disease, or hypertension resulting in total or partial disability or death was accidental and suffered in the line of duty, unless the contrary be shown by competent evidence.
