Suspect processing procedures

Improve suspect processing procedures and contamination avoidance measures. 

D.L. and J.T. Payne, Validate Process Data Automatically, Chemical Engineering, June 1992, 112-116). If a measurement is clearly inconsistent with equipment operation that is known to be true, the measurement must then be deemed suspect. Vahdation is the procedure of comparing a measurement to one or more of the following. 

During this time he experienced many complex and controversial cases, the vast majority of which were terrorist-related incidents. His main interests include the chemical examinations relating to firearms casework, research and development work arising from same, crime scene examination, health and safety issues, quality assurance, suspect handling and processing, and contamination avoidance procedures both inside and outside the laboratory. 

Scientists assess a risk to find out what the problems are. The process of deciding what to do about the problem is risk management. The second procedure involved a much broader army of disciplines, and is aimed toward a decision about control. Risk management assumes we have assessed the health risks of a suspect chemical... 

Samples may be fixed, processed and immunostained by a standard procedure (Table 17.11), but, in case of unsatisfactory results, loss of antigenicity must be suspected. The temperature (heat-cured resin sections) and the composition of the fixative, the dehydration of the sample and the polymerization of the embedding resin may all be the cause. 

A tabulation of the relative potential hazards associated with particular variations from the correct process conditions, e.g., charging a reagent too fast, loss of agitation, too much heat, etc. We have found that this section of the questionnaire is not quite as useful as one would first suspect when straightforward operations are involved. When long, complex, multi-step procedures are examined in this fashion, however, the most critical points of interest are immediately highlighted.
