Equipment check-out schedules

Equipment check-out schedule -general electrical installation... 

The detailed schedule of activities for each chemical weapons destruction facility for the upcoming year, identifying time required for design, construction or modification of the facility, installation of equipment, equipment check-out and operator training, destruction operations for each specific type of chemical weapon, and scheduled periods of inactivity. 

Adherence to the checking schedule makes or breaks the system. The interval should be based on stability, purpose, and degree of usage. If initial records indicate that the equipment remains within the required accuracy for successive calibrations, then the intervals may be lengthened. On the other hand, if equipment requires frequent adjustment or repair, the intervals should be shortened. Any equipment that does not have specific calibration intervals should be (1) examined at least every six months, and (2) calibrated at intervals of no longer than one year. Adjustments or assignment of calibration intervals should be done in such a way that a minimum of 95% of equipment, or standards of the same type, is within tolerance when submitted for regularly scheduled recalibration. In other words, if more than 5% of a particular type of equipment is out of tolerance at the end of its interval, then the interval should be reduced until less than 5% is defective when checked. 

A Planned Preventative Maintenance Programme and Standard Operating Procedure for carrying out the maintenance, should be in place. It should refer to all relevant equipment and apparatus to be included in the programme. Responsible persons, should be fisted, canrying out maintenance in accordance with the specified time schedule. Records should be kept as evidence of maintenance checks and repairs. 

Operator Analyses. The operator analysis schedule (Table 13.5) will depend to some extent upon the cell room configuration, the use of feed brine acidification, and the amount of analytical equipment provided. If the last item is limited, manual analysis will form a primary basis of control. If on-line instrumentation (e.g., density meters) is provided, operator analyses serve as checks on the correct functioning of the instruments. The analyses and frequencies given in the table are typical for a multi-electrolyzer bipolar cell room. The plant operators will also carry out routine analyses for process control purposes in other areas, as given in Table 13.6.
