What do candidates on the Construction Site Safety course actually do?
The course on BS 7375 is often 'tuned' to suit the audience on the day, (dealing with mixtures of electrical engineers, site foremen and managers for example) and our instructors promote structured debates on the key topics within the Standard which are of interest to the candidates.
We look at the way in which electricity is distributed around a construction site: how reduced low voltage systems are used and what they can power; where 230V and 400V supplies are used, etc. It's important that the candidates know about the effects of electric shock so we cover that in detail, making particular mention of the fact that electrical shocks sustained in a construction site scenario are likely to be more dangerous than shocks sustained indoors in a dry environment. The candidates need to know about the dangers of overloading, short circuit and earth faults so we also look at these in a little detail and explain how fuses, circuit breakers and earthing are used to combat these dangers. These important issues are explained in a way that the candidates can understand without getting involved in all the theory behind the issues. The following are extracts from the course notes for this part of the course.
