Quality control/assurance safety

Storage and receiving are activities that can greatly contribute to a safe and economic operation. It is here that quality control can be achieved at minimal cost. Label verification and other quality assurance measures can increase the confidence level that the correct chemicals have arrived, thereby potentially circumventing the use of wrong chemicals. Wrongly shipped chemicals can be returned to the manufacturer with minimal or no cost to the batch operation owner. As with all processes and activities it is of great importance to apply the principles of inherent safety, in particular the minimization and attenuation principles (CCPS G- 41). 

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. 

The quality control of vaccines is intended to provide assurances of both the effieacy and the safety of every batch of every product. It is executed in three ways ... 

While quality was formerly achieved by inspection of final products, it is accomplished now by prevention through controlling critical steps in the production processes along the agri-food chain. Hazard analysis critical control points (HACCP) represent a typical example of such a preventive approach. Although this concept was developed primarily to assure food safety, the basic principle is also applicable to assuring non-safety quality attributes such as color, flavor, and nutritional value. " This section translates the HACCP principles into a critical quality control point (CQP) concept that can be part of a system to assure food quality. 

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. 

In 1998, an evaluation of Lasagna technology was prepared for the U.8. EPA s Rapid Commercialization Initiative. As part of the evaluation, cost estimates were prepared. An example of one of these estimates is given in Table 2. These estimates were determined for core costs only, as noncore costs such as oversight, health and safety, sampling, and quality assurance/quality control can vary significantly from one site to the next. The number of pore volumes of water... 

In addition to the binding constant and safety considerations, economics, and quality control issues also play a role in considering which ligands to use. Because of the difLculty in selectively derivatizing a speciLc hydroxyl or family of hydroxyls, most modiLed CDs of pharmaceutical interest are likely to be complex mixtures (Stella and Rajewski, 1997). Methods to characterize these mixtures, therefore, need to be in place to assure lot-to-lot reproducibility. The costs of acute and chronic safety studies required to evaluate any new CD derivatives are very high, and this prohibits them from being widely evaluated for pharmaceutical applications. 

More emphasis on quality control to assure process and product safety and reliability. More green chemistry to avoid pollution. 

International Conference on Harmonization Guideline on Data Elements for Transmission of Individual Case Safety Reports. This document s efforts focus on quality control/quality assurance endeavors to ensure accuracy and to promote validation in the handling of case safety reports for both preapproval and postapproval periods. It covers both adverse drug reaction and adverse event reports. 

The process industry comprises mainly continuous but batch processes also. The industries involved are chemical, petrochemical, pharmaceuticals, refineries, etc. These are usually very large and complex facilities. The main goal of any process plant is to get the maximum benefit (which means the demanded amount with the specified quality using the less resources) assuring safety and stability of the plant. In order to achieve this goal, control strategies have been applied and evolved over the years as new capabilities were available. From the initial manual control to the current digital distributed control system (DCS). 

Many antigens currently marketed would be inherently toxic except for the fact they have been stringently detoxified. Some of the most successful and durable vaccines today include toxoided forms of tetanus, pertussis, and diphtheria toxins. During the manufacturing process, these toxoids undergo significant chemical modifications, and their toxic properties are effectively eliminated. The safety is assured with every batch release and defined within safety charac-terization/quality control tests, which are not discussed in this chapter. 

Material and product data Data include specifications of feedstock, process water, product and byproducts with composition, instruction on usage and discharge, material safety data sheets, and usable and storage life. Information on quality assurance and quality control of feedstock, process water, products, and byproducts must also be collected. 

Management data It is important to document the number of staff, their position and responsibilities, performance records, administrative instruction, occupational and safety procedures, quality assurance, and quality control procedures.
