1 Definition of likelihood, consequence and risk levels. We have chosen to use qualitative values for likelihood, consequence and risk levels. 1.1 Likelihood and consequence levels. We decided to use four levels for identification of likelihood and four levels for identification. of consequence. The levels are defined in table 1 and table 2. The likelihood levels can be described as frequency values or with respect to how easy it is. for a person to exploit a threat. For some threats it is easier to think of the likelihood in the. form of frequency or a probability value.
Diesel mechanics repair and maintain large trucks, tractors, and buses. Courses in diesel technology or mechanics are generally found as part of certificate, career diploma, or associate's degree programs available at technical institutes and community colleges.
Diesel Mechanics. Diesel mechanics work on vehicles that require diesel fuel, which includes buses, trucks, railroad locomotives and some automobiles. As with all other mechanics, diesel technicians use computer technology to diagnose problems and to test repairs. Although many learn their trade on the job, most employers prefer those with postsecondary training in diesel engine repair. This course of study can last six months to two years.
