7 Electrical Safety


Electrical Safety


Approximately 1000 accidents a year involving electricity are reported to the Health and Safety Executive (HSE), of which 30 are fatal. About 25% of these accidents are attributed to the use of portable electrical appliances and, according to the HSE, could have been prevented. These figures show that the use of electricity in workplaces presents many hazards, which, if not suitably controlled, can cause serious and permanent injury. Employers must ensure that electrical systems and equipment are installed, used and adequately maintained to ensure continued safety. Owing to the complexity and technical nature of the subject the information provided addresses the basic principles of electrical safety as it relates to the day-to-day use and maintenance of systems and equipment. The dental team should recognise the extent of their competence and know when to seek expert advice.

Electrical Hazards

Hazard identification is the first stage in the risk assessment process; therefore, it is advisable to read Chapter 19 in conjunction with the information presented in this section. Although this section does not cover all the stages of risk assessment, it provides an overview of hazards which lead to failures and recommendations on how to control them. Most electrical systems operate at either 240 or 415 volts; any voltage above 55 volts should be considered potentially fatal. The primary hazards associated with the use of electricit/>
