Accident equipment

The academic training of engineers wiUi respect to plant equipment lias tradiUoiially focused on design and predicting performance. Little to no effort was expended in attempting to answer Uie question  

This question requires answers in today s high-tech environment. Failure to properly and realisUcally address and answer Uiis question can result/lead to an  

Industr now know s that equipment sometimes fail partially and sometimes fail catastrophically. In any event, it behooves Uie engineer to carefully and Uiorouglily examine Uie various pieces of plant equipment Uiat can fail. A parUal list of some of the more common equipment Uiat can be expected to fail with some regularity in a plant is provided below. Details are available in Uie literature.  

Deviations, i.e., abnonnal conditions Uiat can lead to failure and/or an accident, generally occur because of. 

Specific coinments/recommendations/or procedures for Uie potential failure of equipment that can be found in a process plant are beyond the scope tins text. However, a short list of the units of concern follows

So far we have discussed modifications to the plant equipment. Accidents can also occur because changes to process materials or conditions had unforeseen results, as the following cases and Section 19.5 show ... 

Should there be contact between people, or their clothing, hair or jewellery and the moving parts of machinery, serious injury may occur. Although design engineering has reduced the incidence of injuries from contact between people and the moving parts of machines in more modem equipment, accidents continue to occur with aged machines...

The application of accident-concentration analysis is not meaningful for small data sets. There must be at least in the region of 50 accident cases. Useful types of data in accident-concentration analysis are location, activity, equipment, accident type, type of injury and part of body affected. The analysis is facilitated if some of the data is coded (i.e. presented on a nominal scale of measurement), especially if large quantities of data are handled. The coding should, however, not be done at the cost of the details in the information. The free-text description of the sequence of events should always be available.
