OSHA
Recognizes CNP Method
OSHA's most recent
2005 update to the Respiratory
Protection Standard greatly facilitated
the use of controlled negative pressure.
The new standard allows for five
short tests rather than eight 1-minute
tests using particle counters.
That's at least a 40% time savings over
all other methods, even qualitative!
Not only is our fit testing method more
reliable, but it saves you valuable time
too. |

EHS Innovators offers complete respiratory
protection compliance, including both quantitative and
qualitative respirator fit testing. EHSI utilizes the OHD Fit Tester 3000
Quantitative Respiratory Fit Tester when performing on-site
quantitative fit
testing for its customers. This computerized device
represents the latest advance in fit testing technology.
It operates on the principle of "controlled negative pressure" (CNP)
to directly measure respirator air leakage rather than the
measurement of particles as an indirect measure of respirator
fit (as does the TSI Portacount). Because of its advanced
technology, our fit tester is more reliable and faster than any
other qualitative (e.g., smoke tubes and banana oil), and even
other quantitative methods. We can fit test more people in
less time with better results.

| Here's why we're better -
- The Fit Tester 3000's accuracy is
calibrated to a traceable NIST standard.
Competitive fit testing devices cannot measure up to
the same level of accuracy, period.
- Particle counters have inherent
errors and biases related to inaccuracies in
particle counting as an indirect means of measuring
facepiece leakage. These biases make the results
less reliable and not reproducible. The test
room environment is NEVER a factor with the Fit
Tester 3000.
- CNP technology uses direct air
pressure measurement in the facepiece instead of
particle migration to measure the mask for leaks.
This gives you a direct measurement of respirator
leakage quickly and accurately regardless of
conditions in the test location. Sampling
biases related to aerosol concentrations, such as
lung deposition and streamlining, are completely
irrelevant, giving a greater degree of confidence in
the fit test results from EHSI.
- Fit testing is done in the
wearer's own mask rather than a sample mock-up worn
by everyone else. This eliminates hygiene
concerns and ensures better acceptance by your
workers.
At EHS Innovators, we sweat the
details to provide the best and most cost-effective
respirator fit testing services available. Our
experience and equipment allows us to do this better
than our competitors.
Respirator fit testing services are
provided primarily throughout the NJ, Philadelphia and
New York City areas. |
