Process Safety related safety standards are often updated, or new standards are developed, following incidents, near misses, or new advances in the safe design of chemical facilities. Whether these new standards should be implemented into existing facilities then becomes an issue that the Process Safety, Engineering and Operating communities need to address. On the surface it would appear that all new safety standards should be applied to existing facilities. However, sometimes the answer is not intuitively obvious because the existing facility may have a very different design approach and design basis to newer facilities producing similar products; therefore it may not be practical, or safe, to blindly introduce new standards into older, existing facilities.
