Description
x
- The Quantum Foam in-ear plug is a disposable, self-expanding hearing protector, available with or without a cord, made of polyurethane foam.
- Made from ultra-soft, hypoallergenic polyurethane foam, it provides a comfortable and effective seal.
- Its conical design and low expansion rate ensure proper insertion into the ear canal.
- The "detectable" model is only available with a cord (903684).
- It features a metallic core in the cord and a metal insert in the plug for detection in case of loss.
FITTING INSTRUCTIONS
- Firmly hold the plug by the stem just behind the last (largest) flange.
- Place the opposite hand over the head and pull the ear to open the ear canal properly.
- Position the first flange of the plug in the canal and push inward while gently twisting the plug. Insert the plug as deeply as possible to achieve maximum noise reduction.
- Check the correct position of the plug in the ear canal. The largest flange should seal the entrance to the canal.
- Ensure proper depth of the plug in the ear canal for optimal attenuation.
- Failure to follow all instructions and recommendations or discontinuing use during exposure will degrade the nominal protection offered, which may lead to serious injuries.
