Summary

You may get the impression from the media that, over the years, ammonia has developed a reputation of being unsafe. But is ammonia less safe than other refrigerants? The main reasons for the continued use of ammonia are high efficiency and its environmental qualities. Accidents happen with all refrigerants, but they are much less likely to occur when codes and standards of good practice are followed. Examples of this are some of the recent accidents in 2013 in China. The investigations following the accidents showed that several codes, which might have prevented the accident, had not been followed. One of the highly critical issues was the qualifications of the people who took on the job of welding1. Another critical parameter is the lack of understanding of why the standards should be followed, e.g. why you need emergency exits and that it is unacceptable to block them2. There have been several examples of this over the years in different parts of the world. You can read more about this on the Internet,3 see examples in the references. This paper is going to look at the most common reasons for accidents involving all types of refrigerant and refrigeration systems and how to avoid the most common accidents by following codes and standards. In a few cases, it is necessary to go further than set forth in standards and codes to ensure a trouble-free and reliable working life of a refrigeration plant, which is so important for the industries using these systems.
