40 ILCS 5/4-110.1
The General Assembly finds that service in the fire department requires firefighters in times of stress and danger to perform unusual tasks; that firefighters are subject to exposure to extreme heat or extreme cold in certain seasons while performing their duties; that they are required to work in the midst of and are subject to heavy smoke fumes, and carcinogenic, poisonous, toxic or chemical gases from fires; and that these conditions exist and arise out of or in the course of employment.
An active firefighter with 5 or more years of creditable service who is found, pursuant to Section 4-112, unable to perform his or her duties in the fire department by reason of heart disease, stroke, tuberculosis, or any disease of the lungs or respiratory tract, resulting from service as a firefighter, is entitled to an occupational disease disability pension during any period of such disability for which he or she has no right to receive salary.
Any active firefighter who has completed 5 or more years of service and is unable to perform his or her duties in the fire department by reason of a disabling cancer, which develops or manifests itself during a period while the firefighter is in the service of the fire department, shall be entitled to receive an occupational disease disability benefit during any period of such disability for which he or she does not have a right to receive salary. In order to receive this occupational disease disability benefit, (i) the type of cancer involved must be a type which may be caused by exposure to heat, radiation or a known carcinogen as defined by the International Agency for Research on Cancer and (ii) the cancer must (and is rebuttably presumed to) arise as a result of service as a firefighter.
A firefighter who enters the service after August 27, 1971 shall be examined by one or more practicing physicians appointed by the board. If the examination discloses impairment of the heart, lungs or respiratory tract, or the existence of any cancer, the firefighter shall not be entitled to the occupational disease disability pension unless and until a subsequent examination reveals no such impairment or cancer.
The occupational disease disability pension shall be equal to the greater of (1) 65% of the salary attached to the rank held by the firefighter in the fire service at the time of his or her removal from the municipality's fire department payroll or (2) the retirement pension that the firefighter would be eligible to receive if he or she retired (but not including any automatic annual increase in that retirement pension).
The firefighter is also entitled to a child's disability benefit of $20 a month for each natural or legally adopted unmarried child less than age 18 dependent upon the firefighter for support. The total child's disability benefit when added to the occupational disease disability pension shall not exceed 75% of the firefighter's salary at the time of the grant of occupational disease disability pension.
The occupational disease disability pension is payable to the firefighter during the period of the disability. If the disability ceases before the death of the firefighter, the disability pension payable under this Section shall also cease and the firefighter thereafter shall receive such pension benefits as are provided in accordance with other provisions of this Article.
If a firefighter dies while still disabled and receiving a disability pension under this Section, the disability pension shall continue to be paid to the firefighter's survivors in the sequence provided in Section 4-114 . A pension previously granted under Section 4-114 to a survivor of a firefighter who died while receiving a disability pension under this Section shall be deemed to be a continuation of the pension provided under this Section and shall be deemed to be in the nature of worker's occupational disease compensation payments. The changes to this Section made by this amendatory Act of 1995 are intended to be retroactive and are not limited to persons in service on or after its effective date.
The child's disability benefit shall terminate if the disability ceases while the firefighter is alive or when the child or children attain age 18 or marry, whichever event occurs first, except that benefits payable on account of a child under this Section shall not be reduced or terminated by reason of the child's attainment of age 18 if he or she is then dependent by reason of a physical or mental disability but shall continue to be paid as long as such dependency continues. Individuals over the age of 18 and adjudged as a disabled person pursuant to Article XIa of the Probate Act of 1975, except for persons receiving benefits under Article III of the Illinois Public Aid Code, shall be eligible to receive benefits under this Act.
