Sellstrom Disposable Ear Plugs – Bullet Shape – 500 Pair Wall Dispenser

Description

What you should know about hearing protection:

• Exposure to continuous high noise levels causes irreversible hearing loss
• Developing an effective workplace hearing safety program is critical
• OSHA sets the permissible eight hour work day noise exposure level at 90 dBA and only two hours of exposure to 100 dBA
• Many companies place noise level limits even lower than the OSHA standard
• Here are guidelines that some companies apply for increased safety:
  – 8 hours exposure = 85 dBA
  – 4 hours exposure = 88 dBA
  – 2 hours exposure = 91 dBA
  – 1 hour exposure = 94 dBA

About NRR ratings and their practical application in the field

• The NRR ratings found on many hearing protection products in the market, including Sellstrom, have been tested and certified in controlled laboratories. However, working environments are seldom controlled environments
• In the field hearing protection is not always fitted properly leading to noise creep and the potential for hearing damage
• As a precaution NIOSH recommends the following deratings during field use:
  – Ear Muffs – NIOSH recommends derating NRR ratings by 25%
  – Ear Plugs – NIOSH recommends derating NRR ratings by 50-75%
• In some applications, to achieve maximum protection the use of ear plugs and muffs together may be the safest solution. It is estimated that by combining the two, an extra 5 dBs can be added to the overall tested NRR rating
