(a) An employer may include on-site drug and alcohol tests of employees and prospective employees as part of the employer's drug and alcohol testing policy under AS 23.10.600 - 23.10.699. In on-site testing under this section, an employer may only use products approved by the Food and Drug Administration for employee testing and shall use the products in accordance with the manufacturer's instructions. On-site testing under this section may only be conducted by a test administrator who is certified under AS 23.10.650(b).

(b) In on-site testing under this section, the specimen to be tested must be kept in sight of the employee or applicant who is the subject of the test. The test administrator shall

(1) conduct the test in a manner that allows the subject of the test to observe the testing procedure and the results; in the case of a sight-impaired employee, the employee may request the presence of an observer; however, the test administrator is not required to delay collection of the sample or administration of the test because of the sight-impaired employee's request;

(2) complete the sample documentation required under AS 23.10.640(a);

(3) prepare a written record of the results of the on-site test.

(c) An employer may not take permanent employment action against an employee based on an unconfirmed, screen positive on-site test result. If an employer takes temporary adverse employment action based on an on-site test result, the employer shall restore the employee's wages and benefits if the confirmatory test result is negative or if the employee demonstrates that the positive test result was caused by drugs taken in accordance with a valid prescription of the employee or by lawful nonprescription drugs.
