All relevant equipment used for feed preparation should be listed on the Equipment Maintenance and Calibration Chart.

When feasible, each item of equipment should be labelled with the date of the last external service maintenance along with the anticipated date of the next required servicing. Equipment should not be used after the external service due date elapses. Regular maintenance and equipment inspection will alleviate the incidence of leaks such as motor coolant, oil, etc., that may get mixed in and cause contamination of feeds.

Records of internal maintenance procedures, along with internal and external servicing are to be kept by assigned personnel. Internal maintenance check-ups are to be performed by equipment operators or other assigned personnel prior to the use of the equipment as designated in the Service Maintenance Checklist. Service maintenance check-ups should be conducted following manufacturer’s instructions. Results of each service maintenance review are to be recorded in the corresponding Equipment Calibration Chart, by the equipment operator. The equipment operator should either approve equipment for use or reject it if problems are detected. Corrective action with corresponding dates should be noted.

All relevant equipment used in the feedlot for inspection, testing and calibration of measuring equipment should be listed in the form outlined in the Equipment Maintenance and Calibration Chart. Detail equipment capacity, proper usage, permitted tolerances, maintenance schedules and frequency of internal and external calibrations by the designated feedlot employee. Where feasible, each item of equipment should be labelled with the date of the last external calibration and the service performed along with the anticipated date of the next required service. Equipment is not to be used after the due date for servicing when the calibration has expired.

Records of calibration procedures, internal and external calibrations and servicing are to be maintained in the Inspection and Test Equipment File by assigned feedlot personnel. Internal calibration check-ups are to be performed by the equipment operator as indicated on the Equipment Maintenance and Calibration Chart prior to the use of testing and inspection equipment. Calibration check-ups are to be conducted following the methods listed with corresponding instructions where equipment is to be used. Scale tolerances are derived by dividing the scale capacity by 3000 to obtain the minimum graduation. The weight tolerance allowed is within plus or minus 1.5 graduations of the full load of reference weights. Results of each calibration check-up are to be recorded in the corresponding Equipment Calibration Chart.
