When required, post-accident tests must be conducted as soon as practicable. If a test is not administered within two hours, the employer must prepare and maintain a file stating the reasons why a test was not promptly conducted. The employer must also continue to attempt to administer a post-accident alcohol test for up to eight hours and the post-accident controlled substances test for up to 32 hours after an incident.
