1. The employer does not need to count time spent mixing and loading using closed systems (as defined in WAC 296-307-13045 (4)(d)) in determining the need for periodic testing. Closed cabs are not "closed systems." Time using closed systems is still counted for purposes of establishing coverage under this rule and determining the need for obtaining baseline cholinesterase levels.

 

2. The first thirty consecutive day period begins on the first day of handling organophosphate or N-methyl-carbamate pesticides after obtaining the baseline cholinesterase test.

 

3. There is nothing in this rule that prohibits employers from providing cholinesterase monitoring to employees who handle organophosphate or N-methyl-carbamate pesticides for fewer than thirty hours in any consecutive thirty-day period.
