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 systemic sclerosis or death from systemic sclerosis with the circumstances of a person's relevant service:
(1)          inhaling respirable crystalline silica dust, at the time material containing crystalline silica was being:
            (a)          produced;
            (b)          excavated;
            (c)          drilled, cut or ground; or
            (d)          used in construction, manufacturing, cleaning or blasting,

         for a cumulative period of at least 2 500 hours before the clinical onset of systemic sclerosis;
(2)          being treated with bleomycin at the time of the clinical onset of systemic sclerosis;
(3)          inhaling, ingesting or having cutaneous contact with an organic solvent from the specified list of organic solvents for a cumulative period of at least 2 000 hours within a period of ten consecutive years, before the clinical onset of systemic sclerosis;
Note: specified list of organic solvents is defined in the Schedule 1 - Dictionary.
(4)          being treated with an ergot alkaloid for migraine, for at least the ten years before the clinical onset of systemic sclerosis;
Note: ergot alkaloid is defined in the Schedule 1 - Dictionary.
(5)          inhaling respirable crystalline silica dust, at the time material containing crystalline silica was being:
            (a)          produced;
            (b)          excavated;
            (c)          drilled, cut or ground; or
            (d)          used in construction, manufacturing, cleaning or blasting,

         for a cumulative period of at least 2 500 hours before the clinical worsening of systemic sclerosis;
(6)          being treated with bleomycin at the time of the clinical worsening of systemic sclerosis;
(7)          inhaling, ingesting or having cutaneous contact with an organic solvent from the specified list of organic solvents for a cumulative period of at least 2 000 hours within a period of ten consecutive years, before the clinical worsening of systemic sclerosis;
Note: specified list of organic solvents is defined in the Schedule 1 - Dictionary.
(8)          being treated with an ergot alkaloid for migraine, for at least the ten years before the clinical worsening of systemic sclerosis;
Note: ergot alkaloid is defined in the Schedule 1 - Dictionary.
(9)          for clinical worsening of systemic sclerosis manifesting as scleroderma renal crisis only, being treated with 15 milligrams or more per day of prednisone, or equivalent oral glucocorticoid therapy, for a period of at least four weeks within the six months before the clinical worsening of systemic sclerosis;
            Note: equivalent oral glucocorticoid therapy and scleroderma renal crisis are defined in the Schedule 1 - Dictionary.
(10)      smoking at least 20 pack-years of cigarettes, or the equivalent thereof in other tobacco products, before the clinical worsening of systemic sclerosis, and where smoking has ceased, the clinical worsening of
