Maintenance communications

First, the inherent hazards of community maintenance through intensive lawn care are largely reconciled through qualified anxiety. Keeping in mind that...

In this its first forward area mission the i/id Company quite naturally met with problems not found in rear area screening. For one thing, the unit worked in two shifts because of the necessity of a constant daytime screen as well as the possibility of operations at night. (Installations at the rear, it will be remembered, did not include smoke among their daytime antiaircraft defenses.) The problem of security was greater because of the danger of enemy patrols. Communications maintenance increased appreciably and the need for continuous fog oil resupply in an area both difficult and dangerous to reach involved problems unknown at the port screen at Naples. 

Category II Organizational factors. These are technical support and training, commercial pressure, group violation, company communication, maintenance, and recency-related problems. 

In order to be successful any maintenance department needs strong internal customer—suppher partnerships. Such partnerships require opportunity for mutual benefits, predictable performance by each partner, and communication across links. 

The development of computer capabiUties in hardware and software, related instmmentation and control, and telecommunication technology represent an opportunity for improvement in safety (see COMPUTER TECHNOLOGY). Plant operators can be provided with a variety of user-friendly diagnostic aids to assist in plant operations and incipient failure detection. Communications can be more rapid and dependable. The safety control systems can be made even more rehable and maintenance-free. Moreover, passive safety features to provide emergency cooling for both the reactor system and the containment building are being developed. 

A group of computers becomes a network when intercomputer communication is estabhshed. Prior to the 1980s, all system suppliers used proprietaiy protocols to network their systems. Ad hoc approaches were sometimes used to connect third-pai ty equipment, which was not cost-effective in system maintenance, upgrade, and expansion. The recent introduction of standardized protocols has led to a decrease in initial capital cost. Most current DCS network protocol designs are based on the ISO-OSI seven-laver model. 

It is not uncommon to hear the complaint that the maintenance department has never been informed as to what is happening in the plant. If this is a common complaint, the maintenance manager needs to examine the communications in his department. The following are six practical suggestions for improving communications ... 

Training Materiais. Like any other written or audio-visual maintenance tool, training materials of all kinds are basically communication devices, and to be effective, should be presented in a simple straightforward, attractive, and professional manner. 

Pocket Guide. When a new maintenance form or procedure is introduced, a quick reference pocket guide can promote understanding and accuracy. The key to effectiveness is a deliberate design to provide maximum illustrations or examples in simple language. If it cannot be prepared in-house, outside help should be sought. Professionalism is essential to good communications. 

Written Memos. One of the most effective devices for improving maintenance communications is a newsletter or internal memo. The memo s success depends heavily on communicating formal tips and techniques in the mechanics language and using photos, sketches, and drawings generously to get the message across. 

Forty-hour training was required for personnel entering the exclusion zone, and additional supervisory training was required for site supervisors. Site control procedures described in the Site C contractor s SSAHP included maintenance of site control logs at each access point, use of red tape or chainlink fencing to demarcate hot zones, and use of the buddy system in all exclusion and contamination reduction zone areas. Site communications relied almost exclusively on visual sighting of employees the plan did not describe the use of two-way radios. This suggested that all employees in hot zones can be observed continuously from the support zones.

Nickel-Hydrogen, Nickel-Iron, and Nickel-Metal Hydride. First developed for communication satellites in the early 1970s, nickel-hydrogen batteries are durable, require low maintenance, and have a long life expectancy. The major disadvantage is the high initial cost. For these batteries to be a viable option for electric vehicles, mass production techniques will have to be developed to reduce the cost. 

The microprocessor should also be able to support modem communication with remote computers. This feature will enable multiple plant operation and direct access to third party diagnostic and analysis support. Data can be transferred anywhere in the world using this technique. Not all predictive maintenance systems use a true RS 232 communications protocol or support modem communications. These systems can severely limit the capabilities of your program. The various predictive maintenance techniques will add other specifications for an acceptable data acquisition unit. 

Lie a memo to the involved departments operations, laboratory, maintenance, and oil movement. Communicate the purpose, duration, and scope of the test run. Include a list of samples and the required analyses (Table 5-1).
