Toolbox Talks

Make the plugs and muffs fit

Make the plugs and muffs fit

Noise 5 min 29 CFR 1926.101

Why it matters

When noise is over the 1926.52 limits, the employer provides hearing protection and the crew uses it. That is 1926.101. Plain cotton is not protection. Plugs and muffs work only if they fit. 90 dBA is where that table starts, not a number you measured.

The talk

When the noise is over the limits in 1926.52, the employer provides hearing protection and the crew uses it. That is 1926.101. The table in 1926.52 starts at 90 dBA. That figure is where the rule's table begins. It is not a reading you took today. If the foreman gave you plugs or muffs, wear them while the loud work is going. Hanging them on the hard hat does not count. Wearing one plug and talking around it does not count. Put them in before the tool starts, not after your ears are already buzzing. The protection has to be on for the noise, not for the walk back to the gang box.

Plain cotton in the ears is not acceptable protection. Cotton from a kit, a piece of a shirt, a napkin: none of that seals out the noise. It feels like you did something. You did not. Use the earplugs or the muffs the employer gave you. Plugs have to fit. Roll them the way you were shown, put them in, and hold them while they expand. If you let go too soon, they back out and the seal is gone. A plug that is half out is not doing the job. If your hands are dirty, wipe them before you roll a plug. Grit rolled into a plug becomes grit in your ear.

Muffs have to seal around the ear. They do not seal over a hoodie hood. They do not seal if a hard-hat band lifts the cup off your head. The cup sits over the ear, the cushion lies on skin, and nothing is in between. The arms of your glasses can break that seal too. If you need glasses and muffs together, tell the foreman so you get a way that actually seals. If the plugs or the muffs hurt, or they will not stay, do not suffer and do not take them off where nobody sees. Tell the foreman. Pain is not the goal. A seal is the goal.

Key points

  1. Over the 1926.52 limits, the employer provides hearing protection and the crew uses it.
  2. 90 dBA is where that table starts, not a reading you took yourself.
  3. Plain cotton in the ears is not acceptable protection.
  4. Roll plugs the way you were shown and hold them while they expand.
  5. Muffs do not seal over a hood or a hard-hat band that lifts the cup.
  6. The cushion has to sit on skin, with nothing in the way.
  7. Tell the foreman if the protection hurts or does not fit.

Do this

  • Wear the plugs or muffs you were given while the loud work is going.
  • Roll plugs the way you were shown and hold them while they expand.
  • Seat muffs so a hood or a hard-hat band does not lift the cup.
  • Wipe grit off your hands before you roll a plug.
  • Tell the foreman if the protection hurts or will not seal.

Do not do this

  • Do not use plain cotton, a piece of shirt, or a napkin as hearing protection.
  • Do not let go of a plug before it has expanded.
  • Do not wear muffs over a hoodie hood.
  • Do not ignore a hard-hat band that lifts the cup off your ear.
  • Do not take poor-fitting protection off in secret. Tell the foreman.

Talk about it

  1. Which tasks today are loud enough that we need plugs or muffs, and where are they?
  2. Who has muffs sitting on a hood or a hard-hat band instead of on the ear?
  3. If the plugs hurt or fall out, who do you tell before you keep working without them?

This is a short crew briefing. It does not replace a competent person, training, or the law.
