Electrical safety in industry

The paper reviews electrical safety in industry, excluding mining and public electricity supply. A discussion of the incidence and nature of electrical hazards and injuries is followed by a brief consideration of the regulations affecting premises under the Factories Acts*¿which includes building and civil engineering, and cargo handling in docks¿and also recent legislation relating to offices, shops and railways. The importance of standards and the certification of safe equipment is also discussed. In the Sections dealing with specific hazards, particular attention is paid to earthing, circuit protection, fire and explosion hazards, portable apparatus and building and civil engineering. The final Section outlines certain aspects of modern electrical control systems. High-voltage switch gear and substation equipment, and, in particular, protective systems and rupturing duty and capacity, have not been discussed, since it is expected that, at a later date, these will be dealt with in association with electricity supply.
