OSHA is currently not enforcing the recording of hearing loss on OSHA Form 200 unless the shift from the original baseline audiogram at frequencies of 2,000, 3,000, and 4,000 Hz averages 25 dB or greater in either ear.
If an audiogram shows a hearing loss that is recordable on OSHA Form 200, the date that must be entered in column (B) is the date the employee was tested. If a retest performed within 30 calendar days of the initial test shows the hearing loss is not recordable on OSHA Form 200, the original entry may be deleted by drawing a line through it. OSHA adopted the 30-day retest time limit to provide employees a reasonable time to learn about the state of their hearing.
