Local Site Condition Evaluation. In addition to visiting the site, drawing up a contour map and geology reports, acquiring sod-bearing information, and a knowledge of boundaries, setbacks, local requirements, utdity tie-in locations, sewer connections, access to roadways, pipelines, radroads, etc, may be needed to make a fliU assessment. 

Haul distance Although minimum haul distances are desirable, other factors must also he considered. These include collection-route location, types of wastes to he hauled, local traffic patterns, and characteristics of the routes to and from the disposal site (condition of the routes, traffic patterns, and access conditions). 

The electricity generated depends primarily on the speed of the wind at the site of installation. A conventional formula to determine the wind energy, based on the design of the rotor (rotating blades) and the site conditions is given by... 

Induction generator This is a standard squirrel cage motor with additional treatment to weather the site conditions. The normal specifications are generally the same as for a standard motor. The permissible voltage and frequency variations are, however, wider as noted below ... 

The recommended thickness of the total cotit (primer plus paint) will depend upon the site conditions. For a normally clean environment, a coat of up to. 50 microns is considered adequate. For a dusty or humid location requiring constant servicing and cleaning, a thicker coat, say, up to 70-cS() microns, is con.sidered to be adequate,... 

The selection process of power cables is almost the same as that of a bus system discussed in Section 28.3. For simplicity we consider only the basic data for selection which would suffice the majority of applications. For accurate calculations a similar approach will be essential as for the bus systems (Chapter 28). For site conditions and laying arrangements which may influence the basic rating of a cable, corresponding derating factors have also been provided. The information covered here will be useful to users to meet their cable requirements, although the data may vary marginally for different manufacturers. For more data on cables, not covered here, reference may be made to the cable manufacturers. 

The choice of any of the cables mentioned in Table A16.1 w ill depend upon the site conditions, fault level and the voltage rating of the system. A brief comparison of all these insulating systems is given in Table A16.2... 

These are common for all types and sizes of cables, except where noted. Derating of cable ratings resulting from site conditions and laying parameters are provided in Tables A16.17-A 16.26. 

It is possible that at certain installations, even after selecting the size of the cables on the basis of the site conditions and the laying parameters as discussed above, a larger cable may become imperative as a consequence of a higher voltage drop. 

In our sample calculations (Example 3 1.1) we have chosen the colour of the outdoors surface as light grey and taking the vveathering effect into account, have considered the coefficient of both absorption and emission as 0.65. The manufacturer, depending on the colour and site conditions, may choose a suitable coefficient. It is, however, advisable to be conservative when deciding the temperature rise due to solar radiation to be on the safe side. 

Site Conditions. If the licensor s package is at the custom design stage, it is important to review the site conditions to be used in the calculations. Weather data is available for most proposed sites or at least for areas not far away. Decisions are necessary as to how to apply the weather data for example, w hether to use 95% or 99%... 

The most straightforward way of proof testing the equipment would be to reproduce site conditions completely. Under such conditions, the testing would easily establish if the compressor performance requirements are met and if the driver and support systems function as intended and are adequate for the purpose. 

Other items related to the site conditions that should be communicated are temperature range, if outdoor and type of protection, if outdoor (Is there a roof Are there sides Is the entire installation completely open ). The requirement for heat tracing and other details of this nature that the vendor is to include in his scope of supply should be specified. Whether the machine is at grade or is elevated must also be specified. 

If the RFA or other information has indicated a release of hazardous constituents, then from the owner/operator s perspective, the Corrective Action process truly begins. The first step in the process, the RCRA Facility Investigation (RFI), is directed toward development of the engineering information about the site necessary to permit selection and evaluation of remedial alternatives. The main engineering thrust of the RFI is the characterization of site conditions by defining the nature and extent of the problem. 

Based on the screening activities, several alternatives may be identified which are viable options for the cleanup of the site. These alternatives can consist of an individual technology or a combination of technologies which appear to be appropriate for the given site conditions and appear to be capable of meeting the cleanup objectives. 

Equipment shall be suitable for the site conditions as identified on the data sheet.

Site conditions and work activities change constantly. Change, and what effects change have on health and safety, should be included in every health and safety plan. If not, the plan needs to be amended to reflect current site conditions. Individuals names for key on-site positions should be listed in each safety plan. If the personnel change, the plan should be amended. But prior to the amendment, a review of the replacement persons training and qualifications should take place to ensure that qualified persons are chosen. 

Does the site safety and health officer have the authority to upgrade the required level of PPE when site conditions warrant ... 

Chemical intakes are calculated using equations that include variables for e.xposure concentration, contact rate, e.xposure frequency, e.xposure duration, body weight, and exposure averaging lime. The values of some of these variables depend on site conditions and the characteristics of The potentially c.xposcd population. 

The existing site conditions, which can influence the design, constmction and performance of industrial buildings and their operations, include ... 

Insulation is subjected to abuse onsite, in storage and often in transit. To ensure minimum wastage through breakage, contamination or deformation, select products which are resilient or robust enough to tolerate site conditions and malpractice.
