Process Knowledge and Documentation—The main features here are process definition and design criteria, process and equipment design, company memory (management information), documentation of risk management decisions, protective systems, normal and upset con-dtions, and chemical and occupational health hazards.

Consequently, this document is intended not only for those who carry out the assessments, the exposure assessors, but also for those who incorporate the results into the assessment of risk, the risk assessors, and those who must rely on the final results to make decisions, the risk managers. The introduction of vocabulary and criteria is intended to facilitate communication between these groups or, in the case where one person performs one or more of these roles, to facilitate a more comprehensive thought process. It is hoped that these hallmarks of data quality can be incorporated early on in the development of exposure assessments and can allow risk assessors and risk managers to more quickly and clearly identify aspects of assessments that need more work or further justification. 

The facility system safety risk assessment process works such that if the initial risk assessment produces a RAC of 1 or 2, some type of control must be applied. After this control is applied, a second risk assessment or controlled RAC is determined. First, the control rating code is evaluated to ensure that the CRC rules have been met and then to ensure that the controlled RAC is 3 or 4. If the CRC rules are met and the controlled RAC is 3 or 4, the corrective action is taken and the risk has been reduced to an acceptable level. However, if the CRC rules have not been met and/or the RAC remains at 1 or 2, other controls must be applied and the reassessment cycle is repeated. If other controls are not available, then risk acceptance decisions must be made by the appropriate level of management, and risk acceptance decisions must be documented (Fig. 11-4). 

If risk management applies to a more complex or a less well-known process, some experience and methods may be helpful for a more formal risk assessment. They will be discussed following the sequence of risk identification, risk analysis, risk evaluation. They also facilitate proper documentation, which is essential for being transparent about decisions. 

Development of the legislative reqnirements for the use of limits of acute toxicity can help to achieve a better compatibihty and enable the comparison of risk evaluation processes connected with toxic substances. This could strongly improve the decision process of risk assessment performed by managing authorities responsible for EEP, as well as those preparing and evaluating the safety documents. 

In electricity distribution asset management, we want to use risk assessment as a tool to analyze risk, to provide increased understanding of the risk problem and to structure and document the results. The aim is to provide input to the decision making process, where the acceptable risk problem is addressed. 

First Phase The first phase is reviewing and improving operating practices. It is important to document the existing processes that create hazardous wastes. Documentation activities should compile management policies and procedures, employee training, maintenance practices, purchase of hazardous materials, risk analysis, and process decision-making. 

A numerical level of risk acceptance is specified where quantitative evaluation of the probabilities and consequences of an incident have been performed. The documentation may also be used by senior management for budgetary decisions or for additional cost-benefit analyses. The values of risk for many industries and daily personnel activities have been published and are readily available for comparison. These comparisons have generally formed the basis of risk acceptance levels that have been appHed in the process industries in various projects.
