Use

From the OSHA Benzene Standard: “Emergency examinations: If an employee is exposed to benzene in an emergency situation, the employer shall have the employee provide a urine sample at the end of the employee's shift and have a urinary phenol test performed on the sample within 72 hours.” This latter statement has been interpreted to mean that the laboratory must receive the urine specimen within 72 hours and that testing has been initiated, not necessarily completed. “The urine phenol shall be corrected to a specific gravity of 1.024”.1 (See Benzene Metabolite Profile, Urine [007732].)
