Safety in Electrical Design
Dates to be advised. Please contact Barbara Steel on
B.Steel@surrey.ac.uk for further information.
SAFETY AND LIABILITYIt is recognised that no product can be absolutely safe. At the same time the laws for product liability ensures that people who suffer damage from a design defect can win compensation without having to prove negligence. Manufacturers, managers, suppliers, users and even individual designers can all be held liable. Therefore there must be a design strategy based on competence which will, as far as reasonably possible, avoid an error or failure in information which will lead to a defect.
SECURITY AND REALITYThis course will identify the essential considerations and techniques for safety in designs and set them in context with examples from real cases. With this information you will be able to take competent decisions and measures to protect your company, yourself and the users of your products within the real restraints of time, cost and available technology.
KEY BENEFITS OF THE COURSE
- Learn specific techniques for safety in design covering circuits, components, materials and all credible hazards.
- Discover the common threads that are found in standards and regulations for safety.
- Understand how these essential requirements are realised and applied in different products.
- Examine how the practical limitations of cost, technology, performance and time constraints will affect your decisions.
- Discuss with the presenter and other course members experiences and feasible options.
- Gain confidence to decide what must be done for every case.
- Apply what you have been told in practical sessions to test what you have learned.
- Develop a strategy for safety in designs that are appropriate for your products and your company.
WHO SHOULD ATTENDManagers, designers, consultants, project engineers, manufacturers, safety, test and maintenance engineers.
Course ProgrammeDuring each session there will be:
i) A presentation of the essential elements of the relevant papers.
ii) A practical example (where relevant) and questions to the course members to test understanding on the subject presented
iii) General questions and discussions
The presentations will have scope to follow up in more detail any points arising that are of particular interest.
Papers on each subject
- European standards institutions
- The Low Voltage Directive
- Safety Marks and Mark issuing bodies and schemes
- Lists of referenced standards and documents
- Manufacturers Declarations of Conformity

ADDED VALUEThe Safety in Electrical Design Course is listed under the IEE's Continuing Professional Development Scheme. From January 1999 the CPD Points System will be discontinued and replaced by a "level of competency" scale. We are awaiting the IEE's advice on how this scale is assessed and will update this web page once we have the information. Please bring your IEE record card with you when attending the course for updating.
