Toolbox Talk:

Hearing Protection Zones and Signage

June 25, 2025

Some areas of the jobsite require mandatory hearing protection — and it’s not just about noise, it’s about compliance and safety.

Why It Matters:

Exposure to high-decibel noise (85 dB or more) without protection can cause permanent hearing damage. OSHA requires hearing protection in these zones, and signage must be clear to everyone.

Key Points:

  • Know where hearing protection zones are. These are typically near generators, concrete saws, jackhammers, and heavy machinery.
  • Post visible signs in high-noise areas — OSHA requires signage if exposure exceeds limits.
  • Supervisors and crews must enforce protection rules consistently in these zones.
  • Use sound level meters to monitor noise in changing work environments.
  • Temporary zones (e.g. during pile driving or demolition) must still be clearly marked.

If there’s a sign, put it on. If it’s loud, don’t risk it.

Ask the Crew:

  • Do we know where the hearing protection zones are today?
  • Are signs visible and equipment available in those areas?
