5500.6
. Liability for occupational disease or cumulative injury
which results from exposure solely during employment as an employee,
as defined in subdivision (d) of Section 3351, shall be limited to
those employers in whose employment the employee was exposed to the
hazards of the occupational disease or cumulative injury during the
last day on which the employee was employed in an occupation exposing
the employee to the hazards of the disease or injury. In the event
that none of the employers of the last day of hazardous employment is
insured for workers' compensation liability, that liability, shall
be imposed upon the last employer exposing the employee to the
hazards of the occupational disease or cumulative injury who has

alternative thereto. If, based upon all the evidence presented, the
appeals board or the workers' compensation judge finds the existence
of cumulative injury or occupational disease, liability for the
cumulative injury or occupational disease shall not be apportioned to
prior employers. However, in determining liability, evidence of
disability due to specific injury, disability due to non-work-related
causes, or disability previously compensated for by way of a
findings and award or order approving compromise and release, or a
voluntary payment of disability, may be admissible for purposes of
apportionment.
