Electrical Machine Safety

3 day course

With the latest introduction of the ‘Provision and Use of Work Equipment Regulations’ (PUWER), and the associated legislation for power presses, woodworking and lifting operations, this course involves the specific methods necessary to meet the legal requirements.

The course also covers the ‘European Machinery Directives’ and the ‘Supply of Machinery Regulations 1992’ both of which form legislative requirements for machine installation and use.

It is primarily aimed at personnel who hold the responsibility for safety relating to electrical machinery. Generally, these will include Electrical and Mechanical Managers, Engineers and Supervisors, as well as Safety Practitioners and Safety Representatives. It may also be of great benefit to companies that intend to employ electrical personnel to perform additional routine electrical maintenance or servicing duties on a diverse range of existing process control systems related for process or manufacturing.

Basic or fundamental electrical skills, hand tool skills and knowledge of the Electricity at Work Regulations 1989 and BS7671:2001 would be advantageous for this course.
