Fault-finding

This chapter starts with the fault finding chart. It is as wide ranging as possible but cannot hope to identify all of the quirks and idiosyncrasies of particular systems. Nevertheless, I hope it will provide a useful structure to the process of fault identification. The manufacturer referred to above also added that the number of things that can contribute to loss of resolution is almost limitless . I don t think we need to be as despondent as that most problems are easily identified and quickly resolved. The chart is followed by detailed descriptions and advice on particular problems identified within the chart itself. 

It is my belief that aU radiation measuring laboratories should have the following items available and relevant staff trained to use them

The cause of the problem may appear very quickly, but if this is not the case and the difficulty is one of poor resolution, then  

Within the chart, numbers separated by slashes, such as 4/1/1, refer internally to other symptoms/actions within the chart references with numbers separated by dots.

One potential problem to do with the management of the incident register is determining who has access to the information about the incident. On the one hand, it is important that all company employees can read the reported information so that they can pick up lessons learned. On the other hand, the register will probably contain sensitive material that should be kept confidential, as should personal details to do with injuries and any suggestion of fault finding.

For a safety culture change intervention to be successful, there must be a climate of trust between employees and management. This includes declaring a truce and moving the focus away from injury blame fixing and fault finding to a safe space where injuries can be reported without fear of reprimand—a space where employees safety concerns can be freely expressed. This amnesty is the only way to create a climate in which old embedded safety habits and beliefs can change. 

Part of the commitment from the executive leadership team to improve safety culture would be to declare amnesty. This would mean that the playing fields would be leveled and the fault-finding attitude of the past would be set aside. Understanding of the cause and effect of accidental loss will enable line managers to identify all of the accident s causes and not stop the investigation once an unsafe behavior is encountered. Most accidents will have a component where an employee s behavior or actions are questionable, but the focus should now fall on how the system can improve in the future to stop this happening.

There are at least two good semiquantitative packages on the market. These can be used with powders, metals, lumps, pressed discs, liquids and slurries (with He atmosphere), and metal samples. These are very useful for identification or fault finding (e.g., identification of metallic impurities in a slip). With additional information like density, dimension, and elements known to be present or not present, accuracy can be greatly improved. Newer versions of software can be used as an alternative approach to calibration rather than type calibration. Powder samples can be pressed into discs with a wax or H3BO3 powder or put directly onto a Mylar film and analyzed like liquids. 

This approach is beginning to make some inroads into the traditions of blame and denial that burden the health care culture. Medical accidents are stiU laden with seemingly intractable connotations of fault finding, mistake making, or carelessness, and the associated responses of shame and blame. However, research now reveals recurring elements in accidents and near misses culture- and system-based failures in teamwork, communication, and transitions. 

The major components of a compliance system are regular inspections, reporting, incident investigation, follow-up, enforcement, and recognition and reward. The system should emphasize fact finding, not fault finding. That applies to all the safety and security programs and policies described in Chapter 3. Initiation and maintenance of an effective compliance system are important to ... 

Care of instruments begins when it is realized that all are delicate, that they should be kept clean, dry, not tampered with, not tapped, and not subjected to extremes of heat. The more complex, the more sensitive to maltreatment and to adjustment they become. Maintenance requires regular inspections and tests a thorough knowledge of the instrument is required before fault finding (and adjustments) can be carried out successfully.
