The worker appealed a decision denying WSIB entitlement for pulmonary fibrosis and emphysema allegedly caused by occupational asbestos exposure while working as an HVAC technician.

The Appeals Resolution Officer reviewed the medical evidence, including opinions from a respirologist and an occupational medical consultant, both of whom concluded the lung disease was secondary to an underlying connective tissue disease rather than asbestos exposure.

The appeal was denied, as the worker's employment exposure was found not to be a significant contributing factor to the development of the conditions.
