(1) The employer must identify a physician or other licensed health care professional (LHCP) who will:

(a) Provide baseline and periodic cholinesterase testing through the department of health public health laboratory or a laboratory approved by the department of labor and industries.

(b) Interpret cholinesterase tests.

(2) The employer must obtain the LHCP's written recommendation for each employee's blood test and evaluation (including baseline tests) and make sure that the employee receives a copy of the LHCP's written recommendation, either through the employer or directly through the LHCP, within five business days after the employer receives the recommendation.

(3) The employer must make sure the LHCP's written recommendation for each employee's blood test and evaluation is limited to the following information:

(a) The employee's cholinesterase status based on the LHCP's evaluation.

(b) Identification of changes in cholinesterase levels requiring a work practice evaluation for the employee.

(c) Identification of changes in cholinesterase levels requiring the employee to be removed from handling and other exposure to organophosphate and N-methyl-carbamate pesticides.

(d) Guidance on medical monitoring.

(e) Any other relevant information concerning an employee's workplace exposure to organophosphate and N-methyl-carbamate pesticides.

Note:

All testing for an employee should be conducted through the same laboratory. This will allow for accurate comparison between baseline and periodic tests.

(4) The employer must instruct the LHCP to NOT reveal in writing or in any other communication with the employer any other personally identifiable medical information.

Note:

If the LHCP written recommendation contains specific findings or diagnoses unrelated to occupational exposure, the employer should send it back and obtain a revised version without the additional information.

(5) The employer must make sure the LHCP is familiar with the requirements of this rule (for example, by providing a copy of the rule or by confirming that the provider has attended training on the rule).

(6) The employer must post the name, address, and telephone number of the LHCP the employer has identified at the locations where employees usually start their work day.

(7) The employer must make sure written recommendations from the LHCP are maintained for seven years.

Note:

The employer may only obtain the employee's actual test results if the employee provides the LHCP with written consent to share these results with the employer.
