Fatal Accident Frequency Rate FAFR

One approach is to compare the risks, calculated from a hazard analysis, with risks that are generally considered acceptable such as, the average risks in the particular industry, and the kind of risks that people accept voluntarily. One measure of the risk to life is the Fatal Accident Frequency Rate (FAFR), defined as the number of deaths per 108 working hours. This is equivalent to the number of deaths in a group of 1000 men over their working lives. The FAFR can be calculated from statistical data for various industries and activities some of the published values are shown in Tables 9.8 and 9.9. Table 9.8 shows the relative position of the chemical industry compared with other industries Table 9.9 gives values for some of the risks that people accept voluntarily. 

Societal risks are usually given as fatal accident frequency rates (FAFRs). The fatal accident frequency rate is defined as the number of fatal injury accidents in a group of 1000 in a working lifetime (10 hours). 

The output from Stage (c) may be expressed in the form of individual risk or of societal risk. Individual risk is tiie probability of death to an individual within a year (e.g. 1 in 10 per year). Societal risk is the probability of death to a group of people - either employees or members of the general public - within a year (e.g. a risk of 500 or more deaths of 10 per year). Societal risks are usually given as fatal accident frequency rates (FAFRs). The fatal accident frequency rate is defined as the number of fatal injury accidents in a group of 1000 in a working lifetime (10 hours).
