1. GENERAL INSTALLATION INSTRUCTIONS FOR DECONTAMINATION SHOWER MODEL DEC-DS-6 1.1 DESIGN & INSTALLATION The DEC-DS-6 Damping Shower is a walk-through damping shower incorporating fine mist spray nozzles to thoroughly dampen full-body protective clothing. It is designed specifically for the damping of protective clothing prior to removal, avoiding the risk of contact with airborne contaminants. The cubicle is fitted with ten water nozzles positioned overhead, at chest height and at waist level, ensuring a thorough 360 coverage in the shortest possible time. The shower is mounted inside a white double-skinned GRP panelled cubicle with a stainless steel frame, and is fitted with a GRP sump. If the Damping Shower cannot be installed permanently, it is light enough to be moved easily to wherever decontamination facilities are required. As the flow rate is relatively low, water can be supplied by a hose-pipe connected to the unit s inlet manifold. There are four fixing plates drilled 15mm diameter for four M12 holding down bolts with centres 955 x 855mm approx. The water inlet is a 1/2 inch BSP male thread, and is situated just below the top of the unit. Minimum operating pressure is 2.8 bar g. Fitted with ½ BSP Solenoid valve (24V Relay with 240V-24V Transformer), connected to a junction box. 1.2 LOCATION For Decontamination Shower equipment to work effectively when needed, it must be installed properly and in the correct location. Decontamination Shower units should be located in a prominent position and ideally on the same level as the hazard. The path of travel to the Decontamination Shower shall be free from obstructions such as heavy traffic that may prevent the immediate use of the equipment. If there is a doorway in the path of travel, it must not be possible to lock or latch the door against the direction of travel and the swing of the door must also be in the direction of travel of the exposed person. Consideration should be given to the placement of equipment in the vicinity of the Decontamination Shower that is sensitive to being splashed with water, in particular electrical equipment. The work areas beneath elevated Decontamination Showers should also be considered in this regard. When equipment is located indoors, waste water must be contained for subsequent safe disposal or there must be adequate drainage. Furthermore, procedures must be in place for clearing away residue waste water after the use of this equipment. Drainage must be considered, especially if there is a possibility of water spilt on the floor freezing. Where there is a possibility of freezing, equipment shall be suitably protected, or alternatively, a unit specifically designed to operate in such conditions shall be installed. When units are installed outdoors in very hot climates, they should be self-draining, or insulated from the effects of overheating caused by solar radiation, or ultimately, fitted with a water chiller or supplied with chilled water. When planning the installation of Decontamination Shower equipment the advice of a suitably qualified advisor should be sought in order to establish the most suitable choice of equipment, location and procedures for decontamination. In all circumstances installation procedures should be in accordance with local legislation and industry standards. Multiple models with different types of activation should be avoided wherever possible.
1.3 OPERATION DETAILS The Damping Shower starts automatically when a person enters the cubicle and breaks the photoelectric beam. It continues to operate until they leave the cubicle. Eliminating manual control prevents the risk of depositing contaminants on operating devices within the cubicle. 1.4. NOTES During the installation, if advice is required HUGHES SAFETY SHOWERS should be contacted immediately. Further copies of drawings are also obtainable from HUGHES, or for standard products these drawings can be found on the website www.hughes-safety-showers.co.uk. The Decontamination Shower should be initially operated and checked for correct performance after installation and should be checked regularly on a weekly basis. Poor performance should be logged and immediately reported to the management and rectified as soon as possible.
2. GENERAL OPERATION AND TRAINING INSTRUCTIONS 2.1 TRAINING All employees that enter potentially hazardous areas in the workplace must be trained in the use of Decontamination Shower equipment. Where multiple models with different types of activation are installed within the same working area additional training must be carried out covering the different methods of activation. Employees should also be aware of the exact location of all Decontamination Shower units and a record of their training must be kept for a period of 5 years. It is the responsibility of all employers to ensure that their employees are fully trained with regard to Health and Safety at work. Instructions for all emergency equipment shall be readily available and accessible to personnel, whether or not they are employees of the company. To Summarise, the most important factors are to 'know where they are' and 'know how to use them'. 2.2 'Know where they are Initially, this involves showing trainees, new employees and contractors where the units are located in areas where they will work or may work in the future. In most instances this involves a limited number of units. It is important to make each person aware of the position of emergency safety equipment before starting work in any area. Furthermore, it is also important to remind current employees of their locations. 2.3 'Know how to use them' Shower Actuation The shower is actuated when the person enters the cubicle and will automatically switch off when the cubicle is vacated. 2.4 SAFETY POSTERS AND TRAINING FILMS Safety Posters or Safety Training Films are an important way of training employees and visitors. Safety Posters should be displayed in prominent positions to increase awareness in the workplace of the existence of this equipment and to show how it is operated in case of an emergency. Safety Training Films and Safety Posters are available from HUGHES SAFETY SHOWERS and these give clear and concise instructions as to the use of this important lifesaving equipment. See HUGHES web site for examples (www.hughes-safetyshowers.co.uk or www.hughes-safety.com).
3. GENERAL MAINTENANCE AND SERVICING INSTRUCTIONS FOR DECONTAMINATION SHOWERS 3.1 SERVICING Regular servicing and maintenance of Decontamination Showers units is essential in order to ensure correct functionality of the equipment. Hughes Safety Showers can provide regular service visits or training to ensure you receive the maximum effectiveness from your equipment. To assist with recording the servicing of this equipment and to enable a full history to be maintained, HUGHES SAFETY SHOWERS can provide six month service and flushing test tags (Part No. 01 29 169 2009 see fig. 1). These tags are provided with complementary tag holders (Part No. 01 29 169 3152 see fig. 2) that can be permanently affixed to the shower equipment. After six months the service tag will be full and can be exchanged for a new tag and kept as proof of servicing and flushing. All Decontamination Shower equipment should be serviced and cleaned regularly and at least every six months in order to ensure proper operation. Important: Records must be kept for a period of at least 7 years of all weekly activation tests, and a period of at least 5 years for servicing and maintenance. IMPORTANT NOTES: Maintenance and servicing must only be carried out when no other activities are being undertaken in the plant area serviced by the Decontamination Shower equipment. Only trained personnel with in-depth knowledge of this equipment should carry out maintenance and servicing. Full training is available from the Service Department at HUGHES SAFETY SHOWERS. 3.2 WATER QUALITY The equipment should be activated at least once a week in order to check for functionality and to clear the line of any sediment build-up See 3.4 FLUSHING. Periodic analysis of the water quality within the Decontamination Shower equipment is recommended to ensure there is no build-up of harmful bacteria. If necessary, following the test, the unit should be thoroughly cleaned and chlorinated/disinfected. 3.3 SHOWER MAINTENANCE Shower Nozzles The shower nozzles should be unscrewed cleaned and disinfected periodically, to ensure that any build-up of debris is removed and that no bacteria are present. After cleaning (disinfecting) the nozzles, they should be replaced using silicone grease. Care must be taken not to over-tighten the nozzles when replacing them.
3.4 FLUSHING Decontamination Shower units should be activated at least weekly to verify proper operation and ensure that any stored water is clean and fresh. The duration of routine flushing should be sufficient to ensure both the shower and water feed pipe are fully purged with clean fresh potable water; in practice this can mean flushing for up to several minutes. The flushing period is generally regarded as the time it takes to flush three times the volume of the supply pipe. Note: The HUGHES servicing and flushing Test Tags have a box for filling in with this information. (See. fig. 1) Recommended flushing instructions and periods should therefore be individually indicated on each separate unit. 3.5 SHOWER CLEANING Under most site conditions it is necessary to periodically clean the Decontamination Shower equipment. This must be carried out whenever the unit gets dirty. Periodic cleaning clearly indicates that this important equipment is being looked after and is safe for use in cases of emergency. If the unit is no longer needed, it must be emptied of any stored water. (See 3.7 OUT OF SERVICE PROCEDURE below). IMPORTANT NOTES: Abrasives or solvents must not be used to clean the unit as this can damage the surface or affect the instruction stickers. 3.6 IMPORTANT NOTES During servicing and maintenance it is imperative that the temperature of the water delivered from the Decontamination Shower equipment is tested to ensure it never exceeds 38.6 C or drops below 10 C during the operating period of the unit. Temperatures above 25 C can encourage the growth of organisms such as Legionella. 3.7 OUT OF SERVICE PROCEDURE In the event that a Decontamination Shower unit becomes temporarily out of service a standard procedure should be followed. Place a sign on the unit indicating that it is Out of Service. Notify all individuals working in the area that the unit is out of service. Prohibit or suspend any work where there is a significant possibility of requiring the use of the unit.
