Cal. Lab. Code § 3212.4
In the case of a member of a University of California fire department located at a campus or other facility administered by the Regents of University of California, when any such member is employed by such a department upon a regular, full-time salary, on a nonprobationary basis, the term "injury" as used in this division includes heart trouble, hernia, or pneumonia which develops or manifests itself during a period while such member is in the service of such a University of California fire department. The compensation which is awarded for such heart trouble, hernia, or pneumonia shall include full hospital, surgical, medical treatment, disability indemnity, and death benefits as provided by the provisions of this division.
Such heart trouble, hernia, or pneumonia so developing or manifesting itself shall be presumed to arise out of and in the course of the employment. This presumption is disputable and may be controverted by other evidence, but unless so controverted, the appeals board is bound to find in accordance with it. This presumption shall be extended to a member following termination of service for a period of three calendar months for each full year of the requisite service, but not to exceed 60 months in any circumstance, commencing with the last date actually worked in the specified capacity.
Such heart trouble, hernia, or pneumonia so developing or manifesting itself in such cases shall in no case be attributed to any disease existing prior to such development or manifestation.
The term "member" as used herein shall exclude those employees of a University of California fire department whose principal duties are those of a telephone operator, clerk, stenographer, machinist, mechanic, or otherwise, and whose functions do not clearly fall within the scope of active firefighting and prevention service.
