Thorough examination requirement

Annual inspections must be performed by a qualified person due to the more thorough examination required. The higher level of expertise of a qualified person helps to ensure that the inspector is able to identify deficiencies necessitating a greater degree of scrutiny than what would be required in the shift inspection for example, a deficiency that is not apparent in a visual inspection but is detectable through taking apart equipment components. [Pg.172]

Repairs, renewals or alterations required in item 5 of this report, completed at the time of the thorough examination and lest. [Pg.155]

You will need to ensure that all plant and equpment (eg lift trucks, vehicles, gas appliances, machinery guarding, ladders, electrical equipment, lifting equipment, air receivers, ventilation plant) that requires maintenance (eg pre-shift checks, servicing, thorough examinations) is identified and that the maintenance is done. [Pg.7]

Soils are complex systems that require thorough examination in order to place data in a meaningful framework. For instance, Hawaiian soils from areas with essentially identical young basaltic bedrock and similar annual rainfall have been examined (Huh et al. 2002 Pistiner and Henderson 2003), but results are strikingly different. Huh et al. (2002) reported finding a 2x to 6x increase in Li concentration relative to rmweathered basalt and variations in 5 Li between +3 and +10 from lower to upper soil horizons. Pistiner and Henderson (2003) examined nine successive layers of volcanic soil that showed restricted variability in both... [Pg.181]

Flouk has also considered the alkylation reactions of pyrroles and indoles using the same class of catalyst. The report addresses the fact that while catalyst 12 provides high ees in the alkylation of pyrroles (Scheme 15), the same is not true of indoles and catalyst 21 is required instead (Scheme 16). A thorough examination of the accessible transition states for the reaction of iminium ion 184 with pyrrole and with indole led to the conclusion that the two reactions occur through different transition states. Pyrrole adopts a closed transition state reminiscent of that of the Diels-Alder reaction whereas indole adopts an open transition state (Fig. 19) [233]. [Pg.339]

The requirements for hardware validation are identical to those of any other equipment in use, comprising the OQ/IQ/PQ cycle, except that in the PQ, it is the test of software used. The software validation comprises functional testing, in which defined inputs produce outputs that meet expectations or specifications a thorough examination of source codes, database designs, programming standards, control methods, and support documentation or a quality-assurance program that includes alternate plans, contingency practices, record retrieval, and security practices... [Pg.46]

Professional conservation is labor intensive by nature. It requires highly skilled staff and takes a lot of time. Thorough examination must proceed treatment. Every step must be done by hand and should be documented thoroughly. A photographic record must be kept. Even in a nonprofit, regional center, conservation cannot be performed cheaply. In general, our services are appropriate for rare materials but not for the mass of research collections. [Pg.31]

Patients presenting with a retinal detachment typically report an onset of flashing lights (photopsia) and floaters. Patients may also report decreased peripheral or central vision. Any patient presenting with these symptoms requires prompt dilation and a thorough examination of the central and peripheral retina. Slit-lamp biomicroscopy and indirect ophthalmoscopy with scleral depression are... [Pg.614]

The advantage of positional scanning over iterative deconvolution is that the sublibrary syntheses are carried out at once. But the number of split and pool operations that would be required for library synthesis is rather high so that building block mixtures are used in several of the library synthesis steps in order to reduce the number of operations. A thorough examination of the theoretical and experimental aspects of iterative and positional scanning deconvolution has been published [110],... [Pg.18]

In our concluding remarks we can emphasize that depending on the nature of interactions between the components that constitute the medium and the solid, as well as on a combination of external conditions, one may observe the effects of various types and intensity. These include the facilitation of plastic flow of solids, or, alternatively, brittle fracture due to the action of lowered stresses mechanochemical phenomena in the zone of contact mechanically activated corrosion (the stress corrosion) the processes that are close to the spontaneous dispersion (the so-called quasi-spontaneous dispersion), and the true spontaneous dispersion, leading to the formation of thermodynamically stable lyophilic system. A great variety of types of interactions that exist between the stressed solids and the medium in contact with it requires careful and thorough examination of conditions under which... [Pg.727]

Meaningful organic analysis of fluid inclusions requires thorough examination of the disintegrated sands, several steps of cleansing, and extraction with organic solvents, before final microscopic examination. Certain sands may contain fluorescent inclusions, yet be unsuited for biomarker inclusion analysis due to low effectiveness of the cleansing procedure. Such... [Pg.361]

Investigations into automation assembly procedures should first try to ascertain whether and in what scope automation assembly systems can be applied efficiently. This requires a very careful analysis of the assembly tasks as well as a thorough examination of possible alternatives and their profitability. [Pg.356]
