66 -- Anemometers

MSHA IS LOOKIN FOR A VENDOR THAT CAN SUPPLY THE BELOW ANEMOMETER. Specifications for Anemometers: MSHA inspectors are responsible for determining if sufficient quantities of air are being provided in active working areas of the mine environment. The assurance of sufficient air quantities is related to the prevention of the build-up of explosive gases and necessary to assure a sufficient air quantity to dilute and render harmless, the gases and dusts present in the mine environment. The requirements for specific air quantities are stated in 30 CFR Part 75 Subpart D. These instruments are subjected to the harsh mining environment which affects the instruments reliability. The instrument requirements are: „« The unit and readout must not be affected by electromagnetic sources „« The unit should provide for display of the air velocity in feet „« Be proven to provide reliable results in the harsh underground coal mine environment „« Be of rugged construction that has been proven to withstand the underground coal mine environment „« Be able, with proper calibration, to provide results that are traceable to NIST PLEASE RESPOND BY 3:00 P.M.
