ANALYTICAL PROCEEDINGS, JANUARY 1085, VOL 22 35 Courses Safety of Electrical Equipment in Poten- tially Explosive Atmospheres March 2&22, 1985, Burton Sira’s three-day residential course on the above topic, which will be held at Burton Manor, Burton, Cheshire, introduces delegates to the relevant standards and codes of practice and gives guidance on methods of interpretation and practical implementation. Lecturers and tutors are drawn from Sira Safety Services Ltd., Measurement Technology Ltd. and Expo Safety Systems Ltd. Course participants will acquire a sound understanding of the basic require- ments that must be met to ensure the safe operation of instrumentation and other electrical equipment installed where explosive atmospheres may occur (excluding those existing underground in coal mines).The programme progresses from the problems of area classification, through the selection of equipment, to installation and maintenance. As well as lectures and tutorials, there are practical sessions which emphasise the application of intrinsic safety as this is the most common form of protection used for instrumentation and light current elec- trical equipment. The course is suitable for: engineers and scientists engaged in design, development and research; chief engineers and technical managers con- cerned with industrial process control; and engineers involved in installation, maintenance and inspection work. Further information can be obtained from the Conference Unit, Sira Ltd., South Hill, Chislehurst, Kent BR7 5EH. In addition, companies can commission courses on the use of electrical apparatus or instrumentation in potentially explo- sive atmospheres for their employees.For information on these contact G.
