In a draw-out MCC all current-carrying components should be periodically checked for their silver-plating, proper contact area, spring pressure and tightness of joints (this procedure can follow the manufacturer s maintenance schedule) or at least during the six-monthly or yearly maintenance check ups of the busbars and the busbar joints as noted above. The contacts or their springs may be replaced when the contacts are worn out or...

Tests carried out on protection systems comprise factory tests, on-site commissioning tests and maintenance checks. Those made on individual relays will demonstrate the compliance of the equipment with specification and the verification of its operation under simulated conditions, while tests carried out on-site prior to the equipment being put into service ensure that the full protection scheme and associated equipment operate correctly. These on-site tests must be comprehensive and should include ... 

Disadvantages Possible interaction effects on other buried structures (Section 10.6) subject to the availability of a suitable a.c. supply source or other source of d.c. regular electrical maintenance checks and inspection required running costs for electrical supply (usually not very high except in the case of bare marine structures and in power stations where structures are often bare and include bimetallic couples) subject to power shutdowns and failures. 

Once established, many crops need little maintenance. Check them over regularly though, and provide any extra care they need to ensure healthy growth. Freguent inspections become increasingly pleasurable as the crop approaches maturity.

The example cited required 85 C—typically a waste heat temperature for most industrial environments or a temperature readily delivered by solar heating installations. There are no rotating parts requiring maintenance. Check valves regulate the hydrogen flow. Continuous operation is achieved by using multiple hydride beds operated in a staggered sequence. 

All equipment, including balances and hoods, nust be regularly maintained and so documented. Minimally, hoods should be checked on a yearly schedule. Dow Chemical Company uses the label shown in Figure 4 to document hood maintenance checks. Refrigerators and freezers nust have a temperature recorder of some type or be manually checked and the temperatures recorded. This covers the major GLP related items in the analytical laboratory.

Planned maintenance and frequent checks on performance are essential for sterilizers and air filtration systems., Details of maintenance checks should be recorded. 

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. 

The single modules (pump, autosampler, detector) often contain diagnostic functions to give information about their history and current status, such as volume of mobile phase delivered since the last maintenance check, lamp energy, air in syringe, etc. 

Description— These devices provide air to the wearer through a small-diameter, high-pressure hose line from a source of uncontaminated air. The source is usually derived from a compressed airline with a valve in the hose to reduce the pressure. A filter must be included in the hose line (between the compressed airline and the respirator) to remove oil and water mists, oil vapors, and any particulate matter that may be present in the compressed air. Internally lubricated compressors require that precautions be taken against overheating, as the heated oil will break down and form carbon monoxide. Where the air supply for airline respirators is taken from the compressed airline, a carbon monoxide alarm must be installed in the air supply system. Completion of a prior-to-operation preventive maintenance check on the carbon monoxide alarm system is critical.
