6. 6 Michael Scharfenstein scharf@slac.stanford.edu 6 Environment, Safety and Health CXI Final Instrument Design Review, June 3 2009 Hazard Assessment Process The hazard assessment process is a principal factor in the understanding and management of technical risk. Hazard severity is an assessment of the worst potential consequence, defined by degree of injury or property damage, which could occur Probability is the likelihood that an identified hazard will result in a mishap, based on an assessment of such factors as location, exposure in terms of cycles or hours of operation, and affected population. These levels are derived from MIL- STD-882D, Standard Practices for System Safety. Defense Standards are also used by other non-Defense government organizations, technical organizations, and industry
