Hearing Protection Signs FAQs
At what noise level is hearing protection required by OSHA?
OSHA requires hearing protection when noise exposure reaches 90 dB(A) as an 8-hour TWA (action level is 85 dB(A), at which point hearing conservation program measures begin). A hearing protection required sign should be posted at the entry to any zone meeting these thresholds.
What type of hearing protection signs does OSHA require?
OSHA requires that affected employees be informed of noise hazards and hearing protection requirements. Posting signs at zone entry points is a standard and effective method of communicating this requirement.
Should hearing protection signs say Caution or Warning?
Use CAUTION for zones with noise levels at or near the OSHA action level (85-90 dB). Use WARNING for zones with higher noise exposures or where serious injury risk from noise is more acute.
What pictogram is used on hearing protection signs?
The standard pictogram shows a stylized head with hands covering the ears, indicating ear/hearing protection is required. This symbol is recognized under ISO 7010 (M003) and ANSI Z535 standards.
Are hearing protection signs available with specific dB levels?
Yes. Custom hearing protection signs can include specific noise level measurements (e.g., 'Hearing Protection Required - Noise Level Exceeds 95 dB') for process-specific applications.
