(informative) Water temperature Continuous and timely irrigation of affected tissues for the recommended irrigation period are the principal factors in providing first aid treatment Providing water at temperatures conducive to use for the recommended irrigation period is considered an integral part of providing suitable facilities Medical recommendations suggest water at tepid temperatures be delivered to affected chemically injured tissue Temperatures in an excess of 37 ºC have proven to be harmful to the eyes and can enhance chemical interaction with the eyes and skin While cold water temperatures provide immediate cooling after burns or chemical contact, prolonged exposure to cold water affects the ability to maintain adequate body temperature and can result in the premature cessation of first aid treatment Recent information indicates that a temperature of 15 ºC is suitable for the lower parameter for tepid water without causing hypothermia to the equipment user 9 BS EN 15154-1:2006 BS EN 15154-1:2006 National Annex NA (informative) Guidance on UK legislation concerning water quality NA.1 Introduction This National Annex is purely informative This National Annex is based on the Water Management Society (WMS) working party’s, Managing the Risk of Legionnaires’ Disease in Emergency Safety Showers, Eyebaths and Facewash Fountains [1] and the Department of Health’s, Water sources and potential Pseudomonas aeruginosa contamination of taps and water systems [2], and aims to summarize certain key issues This National Annex also draws attention to general recommendations within the UK, and the following underlying principles of water quality: • Assessing the risk; • Taking the appropriate measures Personnel who have an emergency shower within their workplace are advised to refer to the full guidelines for further information This guidance only covers water quality for emergency safety showers and the creation of a Water Safety Plan (WSP) NA.2 System Design When designing safety shower systems where a dedicated cistern is used to provide the required volume and flow water to conform to the recommendations in this standard, the following criteria should be applied: For installations, attention is drawn to the Water Supply (Water Quality) Regulations 2010 [3]; The cistern should be installed to allow easy access for cleaning, providing adequate head room for access to mechanical cleaning equipment; The cistern should be fitted with a separate drain valve at the lowest point to facilitate complete drainage of the unit, the flushing out of sediments and the cleaning/disinfection of chemical residues; The primary outlet to the shower feed should be designed and installed to maximize the flushing benefit of regular testing and purging operations; Provision should be made for secondary draw off from the storage cistern to ensure a flow of water through the tank The overriding design and operational criteria should be to minimize the impacts on water quality caused by stagnation Adverse changes in water quality decrease the risk of infection to traumatized users of the facility Where supplementary heating of the cistern is installed to combat risks to the users of thermal shock induced by drenching with water, the heating arrangement should be designed to ensure that the temperature does not exceed the maximum advised for legionella control in cold water systems, i.e 20 °C (for details visit http://www.hpa.org.uk/webc/HPAwebFile/HPAweb_C/1263812807228) 10 BS EN 15154-1:2006 BS EN 15154-1:2006 NA.3 Water Quality Attention is drawn to the Water Quality Regulations [3] for regulated quality requirements for water in public buildings irrespective of whether or not any non-compliance is due to the domestic distribution system or the maintenance thereof Microbiological water quality requirements are defined in Schedules and of the The Water Supply (Water Quality) Regulations 2000 It is recommended that these should be regarded as the minimum requirements for water managed specifically for provision in the event of a medical emergency as defined by the provision of storage cisterns installed with the sole purpose of supplying emergency safety showers NA.4 Flushing the system NA.4.1 General Shower units should be activated weekly to verify proper operation and ensure that the stored water does not stagnate The duration of routine flushing should be sufficient to ensure both the shower and water feed pipe are fully purged with potable water; in practice this can mean flushing for several minutes To calculate the minimum required duration of flushing, the regime should be designed so that at least three times the pipework volume is discharged on every occasion NA.4.2 Training All employees who may be exposed to potentially hazardous materials should be trained in the use of emergency showers, eyebaths and eye/facewash equipment Employees should also be made aware of the exact location of all emergency showers, eyebaths and eye/facewash equipment, and be able to record details on a flushing record NA.5 Routine testing of water quality Routine testing of the water quality within the emergency shower, eyebath and eye/facewash equipment is required to ensure there is no build-up of harmful bacteria Test records should include details of water quality and temperature (and disinfectant if it is applied in the building) If necessary, following the test, the unit should be thoroughly cleaned and chlorinated/disinfected Records should include details of water quality, both pre-clean and post-clean These records should be kept for a minimum period of seven years Regardless of monitoring results, storage tanks supplying safety showers should be cleaned at least annually in accordance with Health and Safety Commission L8 – Legionnaire’s disease The control of legionella bacteria in water systems Approved code of practice and guidance [4] Regardless of the minimum requirements for tank cleaning safety, showers represent a heightened risk of microbiologic regrowth and associated risks from legionella and pseudomonas bacteria to traumatised users of the facility Therefore, depending on the results of testing at least quarterly, tank cleaning/checking should be considered unless substantial turnover of water in the storage cisterns can be assured Persistent results (three consecutive) in excess of the prescribed quality criteria defined in NA.3 indicate that cleaning of the cistern is required NA.6 Maintenance of emergency shower This type of equipment should be maintained in an efficient state, in effective working order and in good repair All emergency shower, eyebath and eye/facewash equipment should be serviced and cleaned at least once every six months Servicing records should be kept for a minimum of five years 11 BS EN 15154-1:2006 BS EN 15154-1:2006 NA.7 Recording test data and maintenance schedule Recommended flushing instructions and periods should be individually indicated on each separate emergency shower, eyebath and eye/facewash unit Details of flushing should be recorded and records kept for a minimum of seven years References [1] Managing the Risk of Legionnaires’ Disease in Emergency Safety Showers, Eyebaths and Facewash Fountains, guidance produced by a Water
