In the older, induced-draft wooden cooling towers, a common problem is that the wooden slates have broken up. There is usually an access inspection door at the base of the cell. Often, the water distribution holes are plugged or there are large holes broken into the deck. Water is not supposed to overflow around the outside of the cooling tower. On some cooling towers the fans are driven by belts, which can slip or the fan blade pitch is set too low, low being less than 15°, maximum being 23°. 

It obvious a today s demand on repetitive inspections to predict the safety of pressure equipments during the oncoming service period. The acceptance from the industry for this kind of testing is accessible, if you can fulfil this requirement an enlarge in this way the competitiveness. 

Projection radiography is widely used for pipe inspection and corrosion monitoring. Film digitisation allows a direct access to the local density variations by computer software. Following to a calibration step an interactive estimation of local wall thickness change based on the obtained density variation is possible. The theoretical model is discussed, the limitations of the application range are shown and examples of the practical use are given. The accuracy of this method is compared to results from wall thickness measurements with ultrasonic devices. 

The ultrasonic controls section, shown in Figure 7, provides the means for the user to set the operating parameters for the inspection. The majority of the controls are direct equivalents of those found on a conventional ultrasonic flaw detecfor some additional controls are provided to give access to the special features of the CamuS system. The Controls area is sub-divided into three parts. 

Today the demand for inspection of components with complex geometry, difficult access conditions or location in a hazardous environment is steadily increasing. Documentation, reproducibility and minimised health risk for the inspection staff are key issues. This leads to an increased demand for automated inspection, resulting in a need for new, advanced scarmer systems for NDE. 

The use of Lamb waves offers the possibility of rapid long-range in-service inspection. Receiver and transmitter probes are positioned single sided - access is only required from one side of the specimen - in a pitch-catch-arrangement, the receiver being outside tbe field of the specular reflection. 

Most emphasis is placed on a program of rigorous preventive maintenance. Appropriate climate conditions can help to prevent mold attack, which typically only occurs at elevated relative humidity. Storage furniture which provides an effective barrier for insects, regular inspection of the collections, monitoring of all collection areas with insect traps, and access control measures which minimize the chance of insect entry into the collection areas, are some aspects of an effective pest control management program (175). 

After almost 20 years of service, many leaks developed throughout the mill water supply system. Upon inspection, it was found that perforations had occurred beneath large tubercles. Some tubercles were up to 6 in. (15 cm) in diameter. Accessible pipe was water blasted to remove tubercles, and the deepest metal-loss areas (several thousand) were weld repaired. Perforations ceased. 

Identification. Incomplete fusion generally results in discontinuities along the side walls of a joint. When these discontinuities emerge at surfaces, they can be observed visually if accessible (Figs. 15.10 and 15.11). Defects of this type may also be detected by ultrasonics, radiography, magnetic particle inspection, and eddy-current testing. 

The candidate tollers security policy should emphasize the importance of protecting people, property and the operational practices against loss by intentional destruction or theft. During the site visit, check to see if appropriate methods are taken to control entiy and movement of people and vehicles as a security measure. One telltale sign is that you may be denied access to an area because of another company s confidential process. Though an interference, it affirms a sound security practice. Determine whether security inspections are being held during off-duty hours. 

Magnesium anodes are usually built into the object to be protected through isolating sockets or holes (see Fig. 20-6) and joined to them with cables. They must be readily accessible and easily exchangeable for convenient control [4]. The directions for use have to indicate the necessity for an inspection after 2 years of operation. During operation, control can be exercised by electrical measurements (current, resistance). In addition, acoustic and optical methods exist to determine the amount of anode consumption [4]. The life of the anodes is usually more than 5 years (see Section 6.6). 

All respiratory protective systems should be stored in clean, dry conditions but be readily accessible. They should be inspected and cleaned regularly, with particular attention to facepiece seals, nonreturn valves, harnesses etc. Issue on a personal basis is essential for regular use otherwise the equipment should be returned to a central position. Records are required of location, date of issue, estimated duration of use of canisters etc. 

Asbestos An lAQ investigation often includes inspection above accessible ceilings, inside shafts, and around mechanical equipment. Where material suspected of containing asbestos is not only present, but also has deposited loose debris, the investigator should take appropriate precautions. This might include disposable coveralls and a properly fitted respirator.
