9               Factors that must exist
At least one of the following factors must as a minimum exist before it can be said that a reasonable hypothesis has been raised connecting solar keratosis or death from solar keratosis with the circumstances of a person's relevant service:
(1)          having sunlight exposure to unprotected skin at the affected site for a cumulative period of at least 2,250 hours while in a tropical area, or having equivalent sunlight exposure in other latitude zones, before the clinical onset of solar keratosis;
            Note: equivalent sunlight exposure in other latitude zones, tropical area and unprotected skin are defined in the Schedule 1 - Dictionary.
(2)          having sunburn as specified:
(a)          on at least 5 occasions:
(i)            before the age of 20 years; and
(ii)         at least 5 years before the clinical onset of solar keratosis; and
(b)          where the clinical onset of solar keratosis has occurred before the age of 50 years;
Note: sunburn as specified is defined in the Schedule 1 - Dictionary.
(3)          being a prisoner of war of Japan before the clinical onset of solar keratosis;
(4)          having exposure of the affected region to welding light, while arc-welding metal without skin protection, for a cumulative period of at least 12,000 hours before the clinical onset of solar keratosis;
            Note: Examples of skin protection include leather gloves, long sleeve jackets, and a welding helmet with a face plate.
(5)          undergoing organ or tissue transplantation, excluding corneal transplant, before the clinical onset of solar keratosis;
Note: organ or tissue transplantation is defined in the Schedule 1 - Dictionary.
(6)          having PUVA therapy involving the affected site where:
(a)          the first PUVA treatment commenced at least 5 years before the clinical onset of solar keratosis; and
(b)          at least 25 PUVA treatments were administered before the clinical onset of solar keratosis;
Note: PUVA is defined in the Schedule 1 - Dictionary.
(7)          taking hydroxyurea or voriconazole for at least the 3 months before the clinical onset of solar keratosis;
(8)          inability to obtain appropriate clinical management for solar keratosis.
