VAW - Volunteer Ambulance Workers' Benefit
Article 2 - (Volunteer Ambulance Workers' Benefit) COVERAGE AND BENEFITS
14 - Previous disability.

 14. Previous  disability. The fact that a volunteer ambulance worker
  has suffered  previous  disability  or  received  benefits  therefor  as
  provided  in  the  workers'  compensation law, or this chapter shall not
  preclude him from  benefits  for  a  later  injury  nor  preclude  death
  benefits  for  death  resulting  therefrom;  provided,  however,  that a
  volunteer ambulance worker who is suffering from a  previous  disability
  shall  not receive benefits for a later injury in excess of the benefits
  allowed for such injury when considered by itself and not in conjunction
  with the previous disability. Notwithstanding the  foregoing  provisions
  of this section, if a volunteer ambulance worker has previously incurred
  permanent  partial  disability  through  the  loss or loss of use of one
  hand, one arm, one foot, one leg, or one eye, and suffers  the  loss  or
  loss  of  use  of  another  such major member or eye, he may be adjudged
  permanently totally disabled and receive benefits  for  permanent  total
  disability as provided in section eight of this article.
