RISK ASSESSMENT Physical: All equipment found to be defective will be switched off and reported immediately. Visual inspection of equipment will be carried out before use. Leads and extension cables are to be routed so as to minimise the likelihood of damage and trip hazards. Damaged lamps on festoon leads will be replaced, and only moulded socket holders will be used on sites. Only equipment operating at a safe voltage will be permitted on site; higher voltages must be authorised in writing by management prior to use. Managerial/Supervisory: Subcontractors will be made aware of the above policy concerning use of electrical equipment. Trained first-aider(s) will be available on site at all times when electrical equipment is in use. Management are responsible for ensuring that attention is paid to site electrical requirements, including arrangements for design, testing and installation of circuits and their protection by fuses, residual current devices or similar. The use of electrical equipment will be monitored to ensure safe use. Management will ensure that only trained and competent persons test, repair and maintain portable electrical equipment. Operatives will be trained in the precautions and safe use of portable electrical equipment. Site first-aiders will receive training in electric shock AL SEAL CONTRACTING HSE PROCEDURES Page 5 of 11
