They, therefore, apply directly to the ҹ޸þ and to ALL departments and activities under its control. These Regulations obviously have much wider application in the Science, Electrical, Engineering departments and the Buildings Office. Every Head of Department will have to assess the impact of this legislation in each area under his/her control and assess the risks to staff, students and others where electrical equipment is used. The risks inherent in electrical installations are potentially fatal. Defective plugs, sockets and leads cause more electrical accidents than the appliances themselves. 18.10.2 HAZARDS OF ELECTRICITY The main hazards associated with electricity are: Electric shock, the consequences of which are related to magnitude and duration of current passed through the body and the actual physical path taken by the current. Burns that can occur externally or internally caused by the passage of current through the skin from short circuits or electric arcing. Fire and explosions caused by sparks, arcs, short circuits, overloading and old wiring or working in hazardous atmospheres. 18.10.3 RISKS The risks associated with the aforementioned hazards are to be assessed by the Department (using the appropriate technical input where necessary). These assessments shall be carried out using: Check lists provided (where applicable) and Departmental Hazard Identification/Risk Assessment Work Sheets contained in Document No.3 i.e. Departmental Hazard Risk Assessment (D.H.R.A.). 18.10.4 ARRANGEMENTS AND CONTROLS REQUIRED FOR ALL AREAS These hazards and risks will be minimised by the following arrangements and controls: A competent person should inspect all new equipment, or even locally made apparatus, before being put into service. This would also apply to plugs, cables and fuses etc. The provision of sufficient socket outlets and avoidance/minimisation of the use of adapters. Overloaded sockets can lead to fire hazards The visual inspection by the occupier of cables and plugs to electrical appliances in the office at regular intervals. Ensure that the grounding system is adequate and tested periodically. Consider the use of residual current circuit beakers The prompt reporting of fault signs such as faulty switching or intermittent stopping. This may indicate an internal fault such as a loose wire and could cause external metal work to become alive. The switching off of equipment before unplugging and at end of working day. The testing of residual current devices (RCDs) monthly by a competent person The prompt reporting of faults to the Buildings Office and the prompt repair of such faults by the Buildings Office. Ensure plugs, adapters, cables and fuses are appropriate to the loads being used (plugs and fuses should bear the ASTA stamp) All electrical installations and apparatus should conform to ETCI Electrical Safety Regulations. A trained electrician should carry out the installation, testing, maintenance and repair of all electrical equipment. Make sure all electrical apparatus is properly earthed and where possible, use residual current devices (RCD's) Ensure personnel are familiar with electrical fire fighting techniques. Always switch off the power, if possible, and use, if required, a carbon dioxide (BLACK) or dry powder type extinguisher. DO NOT USE WATER OR FOAM. Ensure direct contact is prevented from electrical apparatus by insulation, enclosure or placing the live parts in such a position they cannot be touched. 18.10.4 ALL AREAS (contd.) Provision of isolation means to disconnect cables or apparatus from source of supply Protection from electric shock may be prevented by special safety measures such as: using lower voltage supply insulate and /or enclose live components ensuring all capacitors are discharged (see below) preventing parts from becoming live by: grounding and automatic disconnection double insulation Separating the supply from mains and earth. the use of appropriate PPE 18.10.5 ARRANGEMENTS AND CONTROLS The details of the Arrangements and Controls in place and those required in the short, medium and long term, shall be set out by the Department in the forms provided in Document No.4 i.e. Departmental Safety Action Plan (D.S.A.P.). These Arrangements and Controls shall be reviewed and updated on a yearly basis. 18.10.6 RESPONSIBILITIES The following personnel are responsible in the Department for ensuring the implementation and ongoing compliance with the aforementioned arrangements and controls.
