Supplier data: 29dB. Reality, as used: 5dB. You need to know this...
We have developed a real-world passive PPE performance calculator based on the latest research into the factors that affect attenuation in the workplace, not just in the lab. This allows you to make a realistic estimate of the actual attenuation that is being achieved in your working environment rather than the assumed figure from the (almost irrelevant) supplier data.
It also allows you to assess the effects of changes to improve protection. The result is an evaluation of your Return on Investment (RoI) for your PPE regime.
How does it work?
Simply enter a few key items of information about your PPE (both plugs and muffs) use covering the following:
- Assumed attenuation (supplier data)
- Measured wear rate
- Are safety glass worn?
- Are safety goggles worn?
- Is a mask worn?
- Is the headband stretched?
- Is a seal damaged?
- PPE fit-test/training?
- Costs?
The calculator then provides you with a realistic estimate of the actual attenuation being achieved. In most cases, this is likely to be in the range 5dB - 10dB, not the assumed 20dB - 30dB. You really need to know if this is the case.
