The 3M Occupational Health and Environmental Safety Division has been helping to protect people at work for 30 years. Excessive Noise and Hearing Loss

The Dangers of Over Protection

It may be tempting to pick the hearing protection with the highest level of protection (or attenuation), however ‘over attenuation’ can bring its own problems. If the sound level at the ear is reduced too far, the wearer can become isolated, unable to hear colleagues‘ voices, moving vehicles, warning sounds, or alarms

Hearing loss caused by exposure to noise at work continues to be a significant occupational illness.

Step by step guide to using the Optime™ Alert System and Sound Check Meter

1. Measure the noise level

2. Identify the corresponding icon

A detailed noise assessment which you may have already carried out will identify the noise level.

The Control of Noise at Work Regulations 2005 Peak level at Limit Value

Peak level at Lower Exposure Action Value

- 140 -

RED 3 OPTIME™ ALERT SYSTEM 95 dB(A) - 110 dB(A)

You are above the permitted exposure level, hearing protection is compulsory. Ideal for all frequencies.

RED 2 OPTIME™ ALERT SYSTEM 95 dB(A) - 105 dB(A)

You are above the permitted exposure level, hearing protection is compulsory. Ideal for high and medium frequency noise.

RED 1 OPTIME™ ALERT SYSTEM 87 dB(A) - 98 dB(A)

You are above the permitted exposure level, hearing protection is compulsory. Ideal for high frequency noise.

YELLOW OPTIME™ ALERT SYSTEM 83 dB(A) - 93 dB(A)

You are above the permitted exposure level, hearing protection is compulsory.

GREEN OPTIME™ ALERT SYSTEM RNR* < 85dB(A)

Hearing protection is not compulsory but is made available to workers for their comfort and protection.

Noise Regulations Under the Control of Noise at Work Regulations 2005 a new Limit Value of 87dB(A) at the ear (under hearing protective equipment) must not be exceeded, and the Upper Action Level becomes 85dB(A) and the Lower Action Level becomes 80dB(A). Whilst a reduction of 5dB(A) may not at first glance appear significant, it is worth noting that a reduction of just 3dB(A) is roughly equated to halving the sound energy level.

The Optime™ Alert System by 3M makes for a quick and easy Hearing Protection Equipment selection process Choosing the correct hearing protection for your needs can be difficult; the hearing protectors should neither over nor under protect the user. With this in mind 3M has an easy to use Optime™ Alert system for 3M™, E-A-R™ and Peltor™ Branded Hearing Products that aids correct selection of hearing protection appropriate to noise level.

Alternatively the 3M™ Optime™ Sound Check Meter will indicate the average noise in your work place area when left there to stabilise.

3. Choose your preferred hearing protection equipment

PLEASE NOTE: At levels above 95dB(A) you will need an accurate noise assessment to correctly select the product. Green and Yellow marked products are not suitable for use in low frequency noise.

Use the icons related to the products to choose your preferred 3M™, E-A-R™ and Peltor™ Hearing Protection Equipment.
