Fatal accident rates

Risk indices are usually single-number estimates, which may be used to compare one risk with another or used in an absolute sense compared to a specific target. For risks to employees the fatal accident rate (FAR) is a commonly apphed measure. The FAR is a singlenumber index, which is the expected number of fatalities from a specific event based on 10 exposure hours. For workers in a chemical plant, the FAR could be calculated as follows ... 

Another approach is to use government and private mortality and injury statistics. Calculated absolute risk estimates (the probability per year of a worker being injured or killed) can be compared to those de facto worker risk standards. For example, in the United Kingdom, industry and government alike are using the fatal accident rate (FAR, see Glos-...

One of the most popular risk policies employed by industry is tlie FAR Concept (Fatal Accident Rate). FAR represents Uie nmiiber of fatal accidents per 1,000 workers in a working lifetime (10 lu-), where a working lifetime is assumed to be approximately lO lu-s. An acceptable FAR (by industries standards) is 4.0. Tliis is made up of ... 

Calculate tlie Fatal Accident Rate (FAR) for the first kind of accident. 

The Fatal Accident Rate (FAR) is tlie nmiiber of fatal accidents per 1,000 workers in a working lifetime (10 lir). A responsible chemical company typically displays a FAR equal to 2 for chemical process risks such as fires, tovic releases or spillage of corrosive chemicals. Identify potential problem areas tliat may develop for a company if acceptable FAR numbers are e.vceeded. 

Fatality Accident Rates (FAR) or Potential Loss of Life (PLL) - A mathematical estimation of the level of fatalities that may occur at a location or facility due to the nature of work being performed and protection measures provided, may be calculated at an annual rate or for the life of the project. 

Another instructive comparison can be made by comparing fatalities in different activities. Here we use the Fatal Accident Rate index (FAR) that gives the number of fatalities for 108 hours of exposure to the hazard [3, 4]. Some activities are compared in Table 1.2. This shows that even with better statistics in terms of fatali-... 

The magnitude of the risk to people is normally taken as the Fatal Accident Rate (FAR). This is calculated by multiplying the size of the hazard (measured in fatalities per hazardous event) by the frequency of the hazardous event (measured in events per year). The FAR has units of fatalities per year. 

The British have published risk statistics associated with different jobs for several decades. Dr. Frank Lees s epic three-volume masterpiece, Loss Prevention in the Process Industries, is without a doubt the premier source of practical and statistical process safety reference material. Within the 3,962 pages of valuable facts, Dr. Lees has published fatal accident rates (FAR). [35]... 

Some British authors from the chemical industry began discussing risks to employees using a concept of Fatal Accident Rates (FAR), as they were called in the early 1970s. There were widely published articles explaining the risks of the 1960s and 1970s. 

In 1992, Dr. Edmund Hambly provided more current Fatal Accident Rate information on the United Kingdom in the article, Preventing Disasters. [36] Dr. Hambly covered 27 individual activities, including such diverse risks as the Plague in London in 1665 (with a FAR of 15,000) to a present-day fatality by a Terrorist Bomb in the London Area (with a FAR of 0.01). Table 1-8 provides his numbers on risks of six different activities. In addition, I have compared Dr. Frank Lees s numbers for the last two risk figures. [35]... 

The hazard analysis of any industrial process impacts on risk assessment. Risk assessment involves the estimation of the frequency and consequences of a range of hazard scenarios and of individual and societal risk. The risk assessment process is shown in Figure 3.1. The risk criterion used in hazard analysis is the fatal accident rate (FAR). The FAR is defined as the number of fatalities per 108h exposure. The actual FAR in the U.K. was 3.5 in the chemical industry in 1975. No doubt the ideal FAR value should be zero, which is difficult to achieve in practice.
