23、 that swimming pools should be managed in accordance with the Health and Safety at Work etc. Act 1 and the Management of Health and Safety at Work Regualations 1999 4. This Code of Practice provides practical advice on ways to comply with the law relating to the management of health and safety in sw
24、imming pools and, in particular, those aspects concerned with pool water treatment. 4.2 Management responsibility 4.2.1 Policy Senior management (those who are legally responsible) should define and document a policy for the general operation and safety of swimming pool water treatment systems. Seni
25、or management should ensure that this policy is communicated, implemented and maintained throughout the organization. 4.2.2 Management review Senior management should review the swimming pool water treatment system, the pool hall ventilation system and the pool hall heating system, in principle, con
26、tinuously, and formally at planned intervals, e.g. at least annually, to ensure its continuing suitability, adequacy and effectiveness. This review should include assessing opportunities for improvement and the need for changes to the swimming pool water treatment system, including the policy. Input
27、s to the management reviews should include: a) feedback from bathers or other users of the pool, suppliers, regulators, regulatory authorities or other external parties; b) information on the performance of the water treatment systems (see 4.3); c) status of preventive and corrective actions; d) inf
28、ormation on any incidents or emergencies; e) follow-up actions from previous management reviews; Licensed Copy: Wang Bin, ISO/Exchange China Standards Information Centre, 10 March 2004, Uncontrolled Copy, (c) BSIPAS 39:2003 BSI 2 December 2003 3 f) changes that could affect the swimming pool water t
29、reatment system, including any changes in regulations or national standards; and g) recommendations for improvement. Outputs from the management reviews should include any decisions and actions related to improvement of the effectiveness of the swimming pool water treatment system and its processes.
30、 Records from management reviews should be maintained (see 4.2.2). 4.3 Measuring, monitoring, analysis and improvement The effectiveness of the procedures and the operation of the water treatment and management system should be measured, monitored and analysed on a regular basis, to identify opportu
31、nities for improvement. As a minimum, senior management should monitor the performance of their pool operation through: a) assessments of individual and overall operations performance; b) control of non-conformance to operational plans, procedures and performance requirements; c) corrective and prev
32、entive actions; d) responding to incidents or other emergencies; and e) any feedback from bathers or other users of the pool, suppliers, regulators or other external parties. 4.4 Training, awareness and competence The management of the swimming pool should identify all training needs. It should requ
33、ire that all personnel whose work is concerned with the swimming pool water treatment system have received appropriate training. The management should establish and maintain procedures to make its employees or members at each relevant function and level aware of: a) the importance of conformance wit
34、h the swimming pool management system policy and procedures, and with the requirements of the swimming pool management system; b) the significant operational or safety impacts, actual or potential, of their work activities and the benefits of improved personal performance; c) their roles and respons
35、ibilities in achieving conformance with the policy and procedures and with the requirements of the swimming pool management system, including emergency preparedness and response requirements; and d) the potential consequences of departure from specified operating procedures. Personnel performing tas
36、ks with significant operational or safety impacts should be competent on the basis of education, appropriate training and/or experience. Personnel performing water quality tests (see 5.5) should be able to distinguish different colours, as the analysis of the results of such tests involves this abil
37、ity (unless photometers are provided). 4.5 Emergency preparedness and response Management should establish and maintain procedures to identify potential for, and response to, accidents and emergencies, and for preventing and mitigating any possible operational and safety impacts. Management should,
38、where necessary, review and revise its emergency preparedness and response procedures, in particular, after accidents and emergencies. Where practicable, the emergency procedures should be tested periodically. 4.6 Non-conformance and corrective and preventive action The senior management should esta
39、blish and maintain procedures for defining responsibility and authority for: a) handling and investigating non-conformance; b) taking action to mitigate any impacts; and c) initiating and completing corrective and preventive action.

40、entre, 10 March 2004, Uncontrolled Copy, (c) BSIPAS 39:2003 4 BSI 2 December 2003 Any corrective or preventive action taken to eliminate the causes of actual and potential non-conformances should be appropriate to the magnitude of problems and commensurate with the impact encountered. The organizati
41、on should implement and record any changes in the documented procedures resulting from corrective and preventive action. 4.7 Swimming pool management system documentation and records 4.7.1 General The organization should establish and maintain information, in paper or electronic form, to a) describe
42、 the core elements of the management system and their interaction; and b) provide direction to related documentation. 4.7.2 Documentation The management system should contain or refer to the following documentation: a) an organization chart showing lines of authority, responsibility and allocation o
43、f functions stemming from senior management; b) the policy; c) procedures covering the operation and safety of the swimming pool water treatment systems, heating systems and ventilation systems; d) procedures covering the identification of non-conformances against clauses of this Code of Practice an
44、d action to be taken to resolve such non-conformances; and e) emergency action procedures (EAPs). It is imperative that senior management ensures the effective implementation of all documented procedures and instructions. 4.7.3 Records A record system should be established to suit particular circums
45、tances. It is important that records: a) demonstrate that procedures have been effectively used and implemented; b) demonstrate compliance under the relevant clauses of this Code of Practice; c) demonstrate that where compliance with clauses cannot be met appropriate risk analysis methods have been
46、applied to determine the safety of the system; d) demonstrate that appropriate means have been applied to ensure identified risks have been minimized and are within legally established safety limits; e) demonstrate that relevant and adequate training has been provided for all staff involved in the s
47、afety and operation of swimming pool water treatment systems, heating systems and ventilation systems; f) be identified, managed and disposed of in such a way as to ensure the integrity of the process and confidentiality of the information; and g) be kept for a period of time so that continued confi
48、dence may be demonstrated for a period of at least five years.

49、ectural, structural and mechanical design of a swimming pool. The design, selection and operation of swimming pool water treatment plant has to take the following factors into account: a) mains water quality, dilution and drainage, coagulation, filtration and disinfection; b) bathing load, circulation rate, circulation hydraulics and turnover period; and c) pool operation, water treatment system and plant room. Pool operators should be aware of the HSE Code of Practice on Legion
