After carrying out the assessment and assuming adequate training, is this task one that can be carried out by a lone worker? This decision is one made by a group leader, please state their name and answer. Group leader name : Prof. S. O’Rahilly Answer: YES Answer: 2. Are there any special considerations for other groups of workers e.g Pregnant and new mothers, young people, cleaners etc. that you have not considered in your main assessment? If so, please make a comment below. SECTION 4- REVIEW Circumstances for Review Default Date review 12 Rules for Electrical Safety (University Health and Safety Division 2001) Electricity has the power to kill. Do a quick check of anything electrical before you use it: include the plug, lead, connections and the equipment. The University inspects and tests all electrical equipment regularly. Portable Appliance Testing (or PAT testing) is carried out to ensure that all electrical equipment is properly maintained. On each item of equipment there should be a 'Tested for Electrical Safety' label which will show a retest date. NEVER USE ELECTRICAL EQUIPMENT WHICH DOES NOT HAVE A CURRENT 'LATEST' LABEL. If the retest date has been passed, please contact the technician responsible for PAT testing and do not use the equipment. In the UK each year there are about 1,000 accidents at work involving electric shock or burns. Around 30 of these are fatal. Even non-fatal shocks can cause severe and permanent injury. In a serious incident in Cambridge in 2000, a student received an electric shock and at another University a student was electrocuted and died due to a badly wired mains plug. So here are your rules 1. Do not touch terminals to "see" if they are live. 2. Do not modify or work on "live" equipment. There are strict laws governing live working. No equipment should have exposed live terminals. 3. Do not obstruct plugs or other means of turning off the power in an emergency. A simple sign or label 'Please turn off in an emergency' may be useful. 4. Do not interfere with any University electrical installations or attempt to repair or alter them in any way. 5. If you make or adapt equipment in any way, it must be assessed by the person in your Department who is nominated as competent to do so. Never build or adapt equipment without their approval. 6. * * * Take action on faulty or damaged equipment switch off and unplug from the supply label to identify that it must not be used report it to the technician responsible. 4. Do not use extension leads unless you have to, never overload and never use where liquids are present. 5. Multiplug adaptors are banned in most departments. They mechanically strain the socket and when overloaded can cause fires. 6. Using an RCD (residual current device) detects some, but not all, faults in the electrical systems and rapidly switches the supply off. 7. Never disconnect an earth wire. 8. Always use the correct fuse. 9. Work safely. Make sure that you have read the instructions for the equipment. Even simple tasks such as wiring a plug can lead to danger - ensure you know what you are doing before you start. Help and advice are available so: Find out who is responsible for electrical safety in your Department. Need advice? First ask: Your Departmental Safety Officer or The University Health and Safety Division.
