Incident investigation general information

The first stage of the site characterization process is the customization of the generic plan developed as part of planning and preparation for responding to contamination threats. In general, the incident commander will develop the customized plan in conjunction with the site characterization team leader. The steps involved in the development of the plan include (1) perform an initial evaluation of information about the threat, (2) identify one or more investigation sites, (3) assess potential site hazards, (4) develop a sampling approach, and (5) assemble a site characterization team. 

Analysis, that can assist with the identihcation of causal factors. The concepts of incident causation encompassed in these tools are fundamental to the majority of investigation methodologies. (See Chapter 3 for information about the Domino Theory, System Theory, and HBT Theory.) The simplest approach involves reviewing each unplanned, unintended, or adverse item (negative event or undesirable condition) on the timeline and asking, Would the incident have been prevented or mitigated if the item had not existed If the answer is yes, then the item is a causal factor. Generally, process safety incidents involve multiple causal factors. 

He or she should not be involved in the investigation itself, but he or she must be made aware of general progress and must receive all pertinent reports and information as soon as possible. In some regards, the incident owner is more like a customer than an active team member. 

An electron is excited if the frequency of the incident electromagnetic radiation matches the difference in energy between two electronic states. This energy difference depends on the electronic structure of the molecule being investigated and its environment. In addition, vibrational and rotational transitions can be excited. Therefore, bands in UV-VIS spectroscopy are generally broad. These bands provide little information about the molecular structure and functional groups present, especially for spectroscopy of liquids and solids [l]-[4].
