All platforms, regardless of the type of grout to be used, should be designed with oil drains. Epoxy grouts are recommended on platform installations because they provide an excellent oil barrier for the concrete below. Cement grouts should be used only for temporary installations. 

AlUiough the design of a process is important, retrofit and temporary installations can play an important role in accident inanagement. 

Artificial ice rinks are frozen shallow ponds, formed and maintained using a brine in tubes buried under the surface. Tubes may be steel or plastic for a permanent rink or plastic for a temporary installation. The brine temperature within the pipes will be about - 11°C, and must be lower for rinks in the open air, owing to high solar radiation loads. Packaged liquid chillers are now generally used, and will be transportable, complete with brine pumps and other apparatus, for temporary installations. 

Several applications of on-line HPLC used as temporary installations for process monitoring are presented in this section. These case histories include... 

Acceptance testing of fusible link fire dampers should always include a random sample actual fusible link (melting) test of the installed assembly that causes the damper to close. Many times an improperly installed damper will not close correctly and the shutter louvers become hung up or twisted. An alternative sometimes available is a link assembly that can be temporary installed that is easily cut by a pair of clippers. The fusible link melting temperature can then be tested separately at a convenient location without subjecting the installation heat or flames for testing purposes. 

Reciprocating compressors are also favored over centrifugal machines for temporary installations such as gas and field-well head service. Also, when low initial capital investment is favored over longterm maintenance costs, reciprocating compressors are used. 

Deviations therefrom—delousing by means of hot air or hot steam—is only permissible insofar as they involve temporary installations, in which the necessary safety for the handling of HCN is not assured. ... 

At the end of September or the beginning of October 1942, a cyanide gas chamber with air-heater was built in Hut 41. The air-heater was connected to the eastern wall. On October 22, the work was finished, and the area was designated Delousing Hut with Bath . The area previously referred to as an undressing room was used as a gas chamber without any major architectural modification, which proves that it was a temporary installation. 

While the files are being copied, a progress indicator will display on the screen showing you how far along the process is. Windows will install files into temporary installation folders on the drive and will ask you to reboot once the copy is complete. If you do not reboot within 15 seconds of the end of the file copy, the system will automatically reboot for you. 

The source of supply for the temporary installation may be from a pietrol- or diesel-generating set or from the local supply company. When the local electricity company provides the supply, the Incoming cable must be terminated in a non-combustible or not readily combustible waterproof and locked enclosure to prevent unauthorized access and provide metering arrangements. 

Clearance is required for the temporary installation or removal of equipment. Clearance is required for lifting areas above and/or under equipment to allow easy removal without obstructions.

Cranes are any lifting machine and associated parts where the movement of the load is not restricted by guides or rails. The description includes permanent fixed installations in buildings such as overhead traveling cranes, temporary installations typically found on construction and building sites, self-contained mobile cranes and hand-operated chain pulley blocks. 

Several plants were noted, during OSART missions, to have poor control of temporary installations. Some of the aspects identified as needing improvement are the following ... 

The lack of control of temporary installation in safety systems can lead to the degradation of the design characteristic of the safety equipment. 

Several plants have established clear and comprehensive procedures on temporary installations. The operation shift supervisor is normally responsible for the final approval of the installation, and has in the control room an updated status of the temporary installations in the plant. TTie number of temporary installations is low, and they are well identified in the field. Very specific control and instructions are set up during outages, when the number of temporary installations normally increases and ftiere are more contractors in the plant. Several plants have indicators on temporary installations. 

Section 551 was introduced by Amendment 2 and applies to low voltage installations that incorporate generating sets running either continuously or in stand-by mode for permanent and temporary installations. This would include, for example, generators supplying temporary accommodation on construction sites and diesel generator sets operating in stand-by mode in hospitals. 

The special requirements of section 604 are for the temporary installations used on site for any type of building and civil engineering work, including... 

Subsection 611-03 recognises that many installations do not have isolating switches and are fed from the supply company s combined cut-out, neutral link and sealing box on the end of the service cable, so in such cases electrical maintenance is restricted to qualified persons. The restriction does not apply to relamping if an isolating switch is available. Supplies are sometimes taken from street furniture to feed temporary installations such as market stalls, Christmas decorative street lighting and small roadworks. Subsection 611-06 requires no impairment of the safety of the permanent installation so it must not be overloaded and the connection must be safe. The temporary installation should comply generally with section 604 for construction sites. 

External influences are dealt with in section 4, which should be considered in conjunction with Appendix B which tabulates the external influences and the appropriate protection against them to be found in Appendix B for the IP Code (ingress protection) and the IK Code (impact protection). The latter is relevant to the temporary installation equipment used on construction sites. 

As the work progressed, the temporary installation had to be altered to suit, involving repositioning apparatus and wiring. This was done with scant... 

The Construction (Design and Management) (CDM) Regulations require the installation designer to cooperate with other designers, such as the architect, the planning supervisor and chent, to ensure that the installation will be safe both initially and subsequently as it is altered to suit the various phases of the construction work. This entails a consideration of the risks and a determination of the means to be used to minimise them. When the site work begins, the electrical contractor responsible for the temporary installation has to plan his work so that it can be done safely. 

Both temporary and permanent electrical supply installations should be installed in accordance with the latest addition of BS 7671 (lEE Wiring Regulations and the Electricity at Work Regulations 1989). Installations, particularly if of a temporary nature, for example in construction works, must be inspected regularly and tested at intervals no greater than those specified by the installation company. It should be noted that if temporary installations are in position for a greater period than 3 months on a construction site then they should be subject to test in line with HSE guidance every 3 months or when they have been altered.
