Quality control, industrial safety

This section discusses common methods for building quantitative chemometric models in PAC. In this field, the user most often desires to build a model that converts values generated by an analytical instrument into values of properties or concentrations of interest for use in process control, quality control, industrial hygiene, safety, or other value-adding purposes. There are several chemometric techniques that can be used to build quantitative models, each of which has distinct advantages and disadvantages. 

The present chapter is supplementary to the reviews mentioned above, and will therefore avoid fundamental aspects of the analytical methods. It will deal briefly with some advancements of analytical methods that appeared in the last few years, it will consider new possible schemes for derivatising the functional groups both as organic compounds and as complexes with transition metals and will list compounds that have found application in industry, as many pertinent analytical methods have been developed for quality control, occupational safety and monitoring of environmental problems. 

The chemical imaging spectroscopy is ap>plied to various fields, from astronomy to agriculture (Baranowski et al., 2008, Monteiro et al., 2007, V. Small, 2006), from the pharmaceutical industry (Lyon et al. 2002, Roggo et al., 2005) to medicine (Ferris et al. 2001, Zheng et al., 2004). But in recent years, has also found use for quality control and safety in... 

Specifications, Standards, Quality Control, and Health and Safety Factors. APA-The Engineered Wood Association represents the softwood plywood and oriented strandboard industries in the areas of specification, standards, and quaHty control (QC). An APA product standard, PSl-95 (6), discusses the above areas in detail. The following listing summarizes plywood characteristics covered in PSl-95. 

Specifications, Standards, Quality Control, and Health and Safety Factors. Formerly, there was an Insulation Board Institute representing the insulation board industry, but the decline in the market and number of producers has led to its demise. Currently (ca 1997), the industry is represented by the American Hardboard Association (AHA). Specifications and standards are found in American National Standards Institute (ANSI) standard for CellulosicFiberboard (7). The standard includes descriptions of the various types and classes of ftberboard, as well as requirements for physical and dimensional stabiUty properties. QuaUty control tests are limited to a few basic strength and stabiUty tests, including bending strength, bond strength, and moisture resistance. 

Specifications, Standards, Quality Control, and Health and Safety Factors. The hardboard industry is represented by the American Hardboard Association (AHA). Specifications and standards are contained in several ANSI standards (8—11). These standards define the various hardboard product categories as well as specific product qualities required for each group. 

Specifications, Standards, Quality Control and Health and Safety Aspects. The OSB industry is represented by the APA—The... 

The audit also emphasizes the self-regulated nature of the industry and the ideal relationship between the agency and the industry. In theory and effective practice, a biomedical company utilizes its quality assurance (QA) unit (in this case, supplemented by credible Part 11 auditors) to maintain control of safety, effectiveness, and quality. The FDA can then review the quality system (QS) and spot-check the other systems such as laboratory or production for most efficient regulatory oversight. In effect, the QA regulates the company and the FDA regulates the QA. 

SACHEM Inc. of Cleburne, Texas, manufactures various concentrations of tetramethylammo-nium hydroxide (TMAH) solutions to meet customer specifications. To ensure consistent performance, electronic industry requires very narrow concentration specifications for the solutions. In SACHEM s quality control laboratory, standardized acids such as HC1 or H2S04 are used as titrants for the TMAH solutions to check their concentrations. The performance of the assay titration is controlled by daily analysis of internal reference standards (IRSs). If the IRS results are within controlled limits, then the assay results of a product can be reported. If not, the results cannot be reported until the root cause is uncovered and eliminated. Safety glasses and gloves are worn while performing this work in the laboratory. 

It may appear much cheaper to employ a culture than add an enzyme to the food process. However, not only economic but also quality control and food safety considerations are involved in decision making in the modern commercial process. Indeed, all three elements of the choice economy, reproducibility and process safety, presented to the manufacturer, have meant that innovations involving enzymes, which may seem fine on the drawing board, have been very tardily adopted by industry. 

In short, most pharma companies assure the quality and product safety related to their laboratories, but are overzea-lous in meeting regulatory requirements to the detriment of cost controls. The responsible segment of the industry is doing more than it needs to do and is spending too much time and too many resources on the vahdation of DIMS. 

Over the last few decades, safety has become one of the most important topics related to food. From this view, quality control of vegetable raw materials has at first to cover the following issues natural and anthropogenic contaminants (e.g. heavy metals, pollution from industrial and private combustions, not professionally deposited waste products, radionuclides), residues of fertilisers (e.g. nitrate), plant-conditioning and plant-protective agents, filth, pests, the microbial status and the occurrence of microbial toxins. It is not possible to discuss all these aspects in detail however, with a focus on herbs and spices, two of them should be stressed more thoroughly. For further information, see [8].
