Calibration & Maintenance
·
The QuantiFit2 is an OSHA accepted Quantitative (QNFT) fit test instrument. It utilizes
the Controlled Negative Pressure (CNP) fit test method as outlined in the Respiratory
Protection Standard - 29 CFR 1910.134, Appendix A.
·
The QuantiFit2 is a highly accurate precision instrument that uses electronic pressure
sensors to detect minute changes to very low levels of negative pressure to an accuracy
of +/- 0.25%. To ensure the instrument operates at the parameters for which it is
designed, OHD requires the QuantiFit2 to receive annual maintenance and calibration
at an authorized service facility.
o
Reasons for Annual Maintenance & Calibration:
·
OSHA Mandate – 29 CFR 1910.134 Appendix A Part I.C.1.(b) – “The employer shall
ensure that QNFT equipment is kept clean, and is maintained and calibrated according
to the manufacturer’s instructions so as to operate at the parameters for which it was
designed.”
·
Best Practice – Annual calibration and maintenance is the accepted industry standard
for Industrial Hygiene and Occupational Health instrumentation.
·
Reliable Results – The QuantiFit2 is a precision instrument that is used to help ensure
employee safety. Critical decisions are made based on the results provided by the
QuantiFit2. All precision instruments require some degree of calibration to ensure the
measurements are accurate.
·
Limits Liability – Complying with the manufacturer’s guidelines establishes good faith
efforts towards employees’ health and safety. Failure to comply with established safety
protocols could be viewed as negligent.
