The worker appealed a decision denying entitlement to benefits for chronic lymphocytic leukemia (CLL).

The worker, a carpenter and maintenance worker, claimed the disease was caused by workplace exposure to benzene and other solvents.

The Appeals Resolution Officer reviewed conflicting medical and occupational hygiene evidence regarding the link between benzene exposure and CLL.

Preferring the medical opinion that the worker was at an elevated risk due to workplace exposures, and noting the worker's lack of non-occupational risk factors, the Officer concluded that the employment exposures likely made a significant contribution to the development of CLL.

The appeal was allowed.
