HB 1456 - DIGEST

     Provides that the claim of a worker who is exposed to a hazardous chemical in the course of his or her employment is presumed to be covered by chapter 51.32 RCW if the worker establishes that: (1) He or she suffered harm or pain; and (2) an accident occurred or working conditions existed which could have caused that harm or pain.  This presumption may be rebutted only by substantial evidence showing that the worker has no physiological symptoms or that the worker's physiological symptoms are not caused or aggravated, in any part, by the exposure.
