§ 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.
