Okla. Admin. Code § 380:16-5-2
In lieu of a citation, the inspecting officer may issue a warning to the employer if such is warranted in the officer's opinion. The warning may require that corrective action be taken immediately; however, failure to comply with a warning will not result in a fine being imposed upon the employer, unless a subsequent citation is issued to the employer.
