Commonly used measurement lacking in 7 key areas Hacking is breaking up a system into its smallest parts, analyzing the strengths and weaknesses of those parts to which changes are then made to achieve a certain goal. Although the term has been negatively branded as a criminal activity, such as when information databases get compromised, it is not that act of hacking that is evil — it’s the goal and methods you use that determines the ethical nature of your hacking. With good intentions in mind, let’s hack the TRIF. TRIF stands for total recordable injury frequency, sometimes termed total recordable injury rate or simply total recordable rate. It’s a ratio of injuries of a certain severity (termed recordable injuries) to hours worked. (# injuries x 200,000) divided by (# hours worked) Why 200,000? Because 100 workers working a 40-hour work week each year is equal to roughly 200,000 hours. The result of the equation is to figure out how many workers would get injured for every 100 workers worth of full-time hours worked. So a TRIF of 5 means that if you theoretically had exactly 100 workers on a site working a 40-hour work week, you would have seen five recordable injuries in the year. If you wanted to do a quarterly TRIF, as some work sites do, you would take the injuries in any given quarter and replace 200,000 with 50,000 and the approximate number of hours worked. The seeds of the TRIF were planted at the beginning of the 20th century with the United States Bureau of Labour’s first full-scale survey of industrial accidents and hygiene.
