Repair sets, maintenance

The service assembled 114 maintenance repair sets for chemical equipment at Edgewood Arsenal between August 1942 and July 1945. These sets consisted essentially of special tools needed for hand-tool repair of flame throwers, collective protectors, air compressors, and portable decontaminating apparatus, as well as gas mask repair tools and test equipment. No single item of field equipment supplied by the CWS proved more useful to the chemical officer in the field than did this set. 

As a minimum, your baseline data set should include the labor, overhead, overtime premiums and other payroll costs of the maintenance department. It should also include all maintenance related contract services, excluding janitorial, and the total costs of spare parts inventories. The baseline should also include the percentage of unscheduled maintenance repairs versus scheduled actual repair costs on critical plant equipment and the annual availability of the plant. 

As-built drawings of the vacuum system within the plant should be available. The vacuum system should be installed in accordance with the set specifications. Records about maintenance repairs and modifications should be filed.

The most commonly used criteria for selection of materials for use in waterfront structures are least first-cost and prior experience. This is unfortunate as least first-cost construction usually does not result in least life-cycle costs when maintenance, repair, and facility life are considered. Prior experience also may not be reliable, particularly if the experience is from a diff erent geographical location or from a structure with a different set of service conditions. In addition, differences in materials, changes in the local environment, and differences in corrosion protection and maintenance may Umit the applicability of past experience to new construction. 

The manufacturing cost consists of direct, indirect, distribution, and fixed costs. Direct costs are raw materials, operating labor, production supervision, utihties, suppHes, repair, and maintenance. Typical indirect costs include payroll overhead, quaHty control, storage, royalties, and plant overhead, eg, safety, protection, personnel, services, yard, waste, environmental control, and other plant categories. However, environmental control costs are frequendy set up as a separate account and calculated direcdy. The principal distribution costs are packaging and shipping. Fixed costs, which are insensitive to production level, include depreciation, property taxes, rents, insurance, and, in some cases, interest expense.

Use maintenance records to inspect HVAC equipment and make sure that it is in good operating condition. Identify items of equipment that need to be repaired, adjusted, or replaced. Record control settings and operating schedules for HVAC equipment for comparison to occupancy schedules and current uses of space. 

System Reliability Service Varied Status reports contain failure, repair, and maintenance data on 450 categories data sets are broader A wide variety of equipment failure and performance records from utilities and manufacturers, plus collected inspection data 75. 

The baseline data set must be updated each time the machine is repaired, rebuilt, or when major maintenance is performed. Even when best practices are used, machinery cannot be restored to as-new condition when major maintenance is performed. Therefore, a new baseline or reference data set must be established following these events. 

Repair and Maintenance. Another job for the stockroom personnel is to do minor repairs and routine maintenance of equipment. Adequate bench space should be set aside for this. 

The requirement for 38 percent online availability means an offline allowance of 62 percent of the time, which can be used for equipment maintenance and repairs. The required capacity factor of 38 percent sets a very low reliability requirement for the equipment and provides a margin for combined equipment failure rates within a processing line. 

KPI system To speed up and anchor CIP in the organization, the companies that set the benchmark in this area establish a clear KPI system linking the operational performance metrics consistently and comprehensively to the overall objectives of the company - and these metrics have to be easily understood and reproduced within standard companywide reporting systems. For instance, at Clariant a number of different KPIs have been defined to track maintenance efficiency, but only a few (e.g., repair and maintenance costs/conversion costs) can really be tracked by the production team on the basis of standardized systems (Fig. 19.6). 

In case of repair or maintenance, a single switchgear compartment will be pneumatically isolated, i.e. the individual protective gas inlet and outlet valves are closed, the isolating switch is set in its OFF position and an (electrical or pneumatical) interlock with the door of the compartment is set off. Thus, the door can be opened to enable access to the internal components. 

U reventative maintenance is a set of practices that you do to prevent problems from happening (or to prevent them from happening frequently). In this chapter, you learned several preventative maintenance techniques to aid you in keeping your computer functional. Some of these techniques include backing up, anti-virus software use and installation, and making an emergency repair disk. 

Any examination of the development of QC technology, which now falls under the broad umbrella of QA, will reveal that it closely parallels the history of the mass production industry. This is not difficult to explain, since the simplified, long-running processes that are the efficiency of automation remove the individual craftsmanship and skill that were once required for quality products . Once this step was taken, the need for an independent responsibility for quality was an obvious reaction, and most of industry now operates with a quality check separate from the production process (in the same way, responsibility for machine setting, repair and maintenance has been delegated to specialist departments).
