Sampling/analysis checklist

Sampling/Analysis Checklist. This module of Risk Assistant, developed specifically for the review of Superfund risk assessments, prompts the user to consider key issues in quality assurance and quality control for sampling conducted at a waste site. It provides a concise summary of whether the standards developed under EPA s Superfund program have been met. 

Servicing standards will also provide advice on safety, checklists for inspections, product operating conditions, inhibitor reserves to be maintained, and provide methods of sampling, analysis, monitoring, reporting, etc. 

It may be desirable to discuss facility siting issues at the beginning of the PrHA sessions. As a minimum, comments and assumptions about siting and plant layout can be included in the PrHA analysis documentation, such as on HAZOP study worksheets. Table 3.2 provides a sample checklist for worker/co-located worker exposures. A sample checklist for facility siting issues is presented in Table 3.3. 

Based on personal experience, the what-if analysis and HAZOP seem to be the most user-friendly methodologies to use. In the following example we describe the what-if analysis procedure and sample checklists typically used for chemicals used in wastewater treatment. Moreover, guide words, meanings, process parameters, and procedures for conducting HAZOP are also presented. 

What-lf Analysis Procedure / Sample What-lf Questions The steps in a what-if checklist analysis are as follows ... 

This useful companion disk contains root cause analysis examples, predefined tree examples, practical checklists that can be customized, and incident evidence photograph examples. It includes a quick checklist for investigators traveling to an incident, examples of methodologies that may be usefiil in training the onsite team, and checklists and samples from the text that can be printed out at the incident site to help organize the team s work. 

AVhile some methods use checklists as the logic analysis step, an understanding of the logic tree approach is still helpful because checklists are developed from logic trees. Checklists are especially helpful when related to human factor issues. A sample checklist is included in Chapter 6 as Figure 6-6 (page 94). 

As when evaluating the published medical literature, results from economic analyses should not be taken at face value . Reports should be detailed, clear and transparent. It is crucial that readers be able to follow exactly what was done (with justification) throughout the analysis. Care should also be taken to determine that the type of analysis performed (for example CEA, CBA) corresponds with the analytical technique purported to be used in the study. Zarnke and colleagues sampled the published literature to assess whether evaluations labelled as cost-benefit analyses met the contemporary definition using CBA methodology. They reported that 53% of the 95 studies assessed were reclassified as cost comparisons because health outcomes were not appraised. Several authors have developed checklists that are useful when evaluating the overall quality of an economic analysis. One of the best-known checklists is given in Box 20.1.

HAZOP and wAat-iJ/safety checklists, two of the most common safety methods in the chemical industry, are explained. Sample process problems, which engineers face every day at work, are shown. Other safety tools, such as fault tree analysis, failure modes and effects analysis, human factors safety analysis, and software safety, are explained. Examples of the use of these tools are also presented. 

Before actually beginning the job hazard analysis, take a look at the general conditions under which the job is performed and develop a checklist. The following are some sample questions you might ask ...
