§ 211.172. Monitoring instruments.

(a)  If monitoring is required, the monitoring instrument must provide a permanent record of each blast.
(b)  The monitoring instrument must be constructed to meet the guideline established by the International Society of Explosives Engineers’ Standards Committee.
(c)  A monitoring instrument shall be calibrated annually and when an instrument is repaired and the repair may affect the response of the instrument. Calibration shall be done by the manufacturer of the equipment, by an organization approved by the manufacturer or by an organization having verifiable knowledge of the calibration procedures developed by the manufacturer. The calibration procedure shall include testing the response of the entire system to externally-generated dynamic inputs. These inputs must test the entire monitoring system at a sufficient number of discrete frequency intervals to assure flat response throughout the frequency ranges specified by this chapter. Dynamic reference standards used for calibration shall be traceable to the National Institute of Standards and Technology. Calibration procedures and documentation of calibration shall be made available for review by the Department.
(d)  A nonalterable sticker that is clearly visible must be firmly affixed to the instrument. The sticker must indicate the name of the calibration facility, the calibration technician, the date of calibration and frequency range of the airblast monitor.
