Re:Respirator Fit Testing

[rodney_bauman@wssrap-host.wssrap.com]

For producing airborne particulates, incense works much better than candles. 
However, incense may not be allowed due to a workplace "fragrance-free" policy.

For such a situation, try using an ultrasonic humidifier or a nebulizer
connected to a bottle of regular tap water.  Impurities in the tap water result
in airborne particulates (sufficient quantities to perform mask fit tests). 
Neither method is expensive.
