Introduction To provide a swimming pool which can be managed as safely as possible, considerations have to start with careful design. All of those involved in designing new pools or upgrading existing ones will need to give the highest priority to ensuring that they provide users and staff with a facility that is safe. Four steps need to be developed in order to achieve this: a) the layout of the pool hall (if any) and the pool basin (including its dimensions, profile and any water fea-tures) should be designed so as to make the safe use and supervision of the pool to achieve without complex or costly management arrangements; b) the layout of the ancillary areas, including the changing, clothes storage, shower and toilet areas, should be similarly designed for safe use; c) the structural elements, materials, finishes and details, including the pool hall enclosure (if any), basin and equipment and the way they are assembled should be those which are the most appropriate to achieving a safe-to-use physical environment; d) criteria relevant for the planning of the safe and functionally correct maintenance. There are specific sources of information from which the technical design and planning standards that are rec-ommended in the design of swimming pools can be obtained. Everyone who is involved in the process of specifying, designing and constructing pools should be familiar with these design and planning standards and should ensure that they are given careful consideration in all pool projects. It is also important to draw the attention of all of those involved in the design process to the implications of their work for the pool operator. What might be thought a small change in the layout of the pool or in the fin-ishes specified could have a significant impact on the ability of the pool to be used safely. If that change is ill-considered and creates a serious design flaw, the result might be an increase in accidents. More likely it will be an increase in the cost of operating the pool (perhaps through the employment of additional staff) in order to compensate for the resulting problems. One way of anticipating the management consequences of design decisions is to include a quali-fied/competent person on the design team. The person should give advice and guidance during the various development stages of the project. This standard includes requirements, recommendations and notes. While compliance with requirements is mandatory, recommendations indicate best practices and notes give additional information and/or explana-tions. SIST EN 15288-1:2008
EN 15288-1:2008 (E) 5 1 Scope This European Standard specifies safety requirements relevant to certain aspects of design and construction of classified pools according to Clause 4. It is intended for those who are concerned with construction, plan-ning and operation of classified swimming pools. It provides guidance about the risks associated by identifying the design characteristics required for a safe environment. The requirements of this European Standard are applicable to all new classified pools and, as appropriate, to specific refurbishments of classified existing pools.
This European Standard has limited application to classified pools which consist of segregated areas of rivers, lakes or the sea but should be followed where relevant. 2 Normative references The following referenced documents are indispensable for the application of this document.

pools Type 2; pools of private use according to 3.4. 5 Safety related design factors and requirements 5.1 General
The requirements of clause 5 refer to pools which are intended for public use within a defined classification. Optional application of requirements to specific types is explained in the related paragraphs. The requirements apply as far as the selected items are present in the swimming pool. As safe operation is influenced by safe design, the design shall take into account the facility’s use, the activity, planned occupancy and its control. Where minimum requirements are given for different types, the designer shall consider the kind of activity foreseen and, should it be more similar to those of another type, refer to the most severe requirements. The occupancy ratio shall be defined at the design stage as the sum of the number of users: a) generated by the water related areas/activities; b) plus the number of users generated by other areas/activities. NOTE 1 A typical occupancy ratio according to a) for swimming pools Type 1, mainly used for swimming and teaching swimming, would be a minimum of 3 m² of water area per bather. As swimming and water-related activities carry an inherent risk (e. g. users have bare feet and wear only bath-ing costumes), the need for specific design requirements shall always be considered. Facilities designed to meet specific needs or programmes (e. g. competitions, special activities, events) re-quire special consideration. Also at the design stage, the needs of the following shall be considered: c) special users (see Bibliography, e. g. with disabilities); d) special installations (e. g. technologies to detect users in a potential risk of drowning video supervision of pool surrounds and/or other areas). Design construction and operation risk assessment shall be conducted for any refurbishment or alteration work. The assessments have to be developed, updated and implemented as and when required to suit the work stages and any relevant occurrences. NOTE 2 A review at fixed intervals has proved to be effective. Requirements and advice of the following chapters should be tested for relevance during the analysis. 5.2 Layout The layout of a facility shall be considered in terms of interaction between its components and between com-ponents and users. Particular attention shall be paid to the intended circulation routes and to the likely behaviour of users. SIST EN 15288-1:2008
EN 15288-1:2008 (E) 8 Significant planning recommendations especially for Type 1 and Type 2 are: a) segregation of the barefoot areas, where reasonably practicable; b) toilets and showers should be located at the access to the pool basins in order to encourage the users to use them before entering the pool basins; c) general circulation routes shall avoid dangerous areas (e. g. deep water, wave pools, pools with high freeboard, areas of potential queuing, e. g. in front of the means of access to water slides) or be suitably segregated from them; d) non-swimmers and paddling pools should be segregated or placed at a suitable distance from pools with deeper water; e) access to the pool surround should be positioned where the water is shallower; f) prevent unauthorized access. 5.3 Safety-Information-Systems A Safety-Information-System (visual and aural) shall be considered. They shall be defined for the particular type and destination of the facility and its safety needs, taking into consideration also the operator’s risk as-sessment. The Safety-Information-System shall consider at least: a) the function of each pool; b) water depths of the pool; c) emergency routes. The Safety-Information-System shall ensure the perception (acoustic comprehensibility/visibility) for all people who are present at the swimming pool (for acoustic systems, see the relevant standards). In certain situations, transmission of safety messages can be improved by the use of computer controlled au-dio equipment (reassigned, emergency based announcement text). The water depths shall be visually indicated by figures of height ≥ 70 mm and in contrasting colour, located to be visible by all people in the water and by those on the pool surround intending to enter the pool basin. Depth indications shall be placed at least: d) at the access to pools; e) in locations corresponding to the maximum and minimum depths; f) in the middle in case of flat or uniformly sloping bottom, or g) where the pool floor profile changes abruptly to a water depth > 1,5 m. Additional functional information are recommended for: h) swimmers/non-swimmers areas; i) the shallow and deep ends of a basin, where appropriate; j) in areas defined for diving. SIST EN 15288-1:2008
EN 15288-1:2008 (E) 9 5.4 Materials All materials and finishes used shall be suitable for the selected use and the respective surroundings and conditions, and able to withstand conditions of high humidity with occasional saturation and/or corrosiveness without encouraging the growth of bacteria. The use of stainless steel with statical function in the swimming hall atmosphere which could be subjected to stress corrosion shall be avoided, unless it can be inspected and regularly cleaned. Where stainless steel is used the grade used should be recommended for that case. Materials and finishing shall be easy to clean, with chemicals when appropriate, to a level of hygiene appro-priate to the location. Manufacturer's recommendations are to be considered. 5.5 General areas for bathers 5.5.1 General The subsequent requirements apply to Type 1 and Type 2 and are recommendations for Type 3. 5.5.2 Circulation areas, floors
Wherever possible, abrupt changes in floor level shall be avoided, particularly in barefoot areas. Single steps on the circulation routes shall a) have a height ≤ 250 mm, with the riser not open; a height ≤ 180 mm is recommended; b) have the edge marked by contrasting colour; c) have a slip-resistant finish complying with relevant standards/regulations. Staircases shall comply with relevant standards. Where ramps on the circulation routes are used, they shall: d) have an inclination ≤ 8 %; an inclination 5 % to 6 % is recommended; e) have a slip-resistant finish complying with relevant standards/regulations; f) be obviously marked at the beginning and end. Circulation routes shall be designed to ensure a free flow of users, avoiding congestion points, constrictions and obstructions. Service accesses should be provided separately to general circulation routes (e. g. direct access from the out-side). To prevent ponding in the barefoot areas, floors shall have a suitable and effective draining system. The incli-nation in direction of the drains shall be between 2 % and 5 %. With an inclination > 3 % particular attention shall be paid to the slip-resistance and to the opportunity to foresee handrails especially for long ramps. 5.5.3 Emergency routes Design of emergency routes shall comply with relevant regulations, but taking into account also the presence of barefoot users. SIST EN 15288-1:2008
EN 15288-1:2008 (E) 10 5.5.4 Walls, buttresses, pillars Projections shall be rounded with r ≥ 3 mm or protected, and sharp edges are not permitted. Areas of glazing shall be: a) made of safety glass able to withstand foreseeable impacts (e. g. caused by water polo balls); b) clearly marked to ensure they are visible to users; c) designed to be readily cleaned and maintained. Walls, buttresses and pillars up to 2 m above floor level shall be flush wherever possible, with a non-abrasive finish. 5.5.5 Lighting, illumination and glare prevention Suitable and sufficient lighting shall be provided throughout the facility, by the use of natural light so far as it is reasonably practicable. If natural light is used in indoor pools, orientation and direct sunshine effects shall be considered during the design stage. Natural lighting and artificial illumination shall be designed to minimize reflection in the main direction of view. The minimum illumination level for the various areas shall be: a) Circulation routes 1)
100 1) Lux b) Plant rooms
100
Lux c) Changing rooms, showers, toilets 100
Lux d) Water areas 1)
200 1) Lux
e) Emergency light
in accordance with EN 1838 Where necessary for special illumination effects, lower illumination levels shall be allowed in the circulation routes and above the water areas by provision of supplementary lighting in the event of an emergency and provided suitably increased supervision is ensured.
To increase visibility and improve safety, underwater illumination is recommended for pools with deep water. NOTE Diving pools and facilities for competition as well as special events purposes, may need different illumination. For water areas the uniformity ratio of illumination at the water level shall be 0,7. For other areas, illumination shall be reasonably uniform, to avoid shadows and other effects that disturb visibility. The design of the illumination system shall consider maintenance and repair activities. All electrical fittings shall be designed and installed in accordance with HD 384.7.702 S2.

EN 15288-1:2008 (E) 11 5.5.6 Acoustic conditions Acoustic design of indoor swimming pools shall ensure that reverberation time doesn't adversely influence communication. NOTE Recommended reverberation time range is 1,5 s to 2,0 s. 5.5.7 Pool hall heating and ventilation guidelines To provide a pool hall climate comfortable and to avoid possible damages to the structures, an air treatment and heating system shall be designed for indoor pools when the natural climate does not provide the appro-priate conditions. The design of the air treatment and heating system shall take into account: a) the relationship between air temperature and humidity; b) the pool water temperature; c) the need to minimize concentration of pollutants, specifically those that are detrimental to health and pol-lute the atmosphere (e. g. chloramines). NOTE Some typical physical values of the air for indoor swimming pools halls are: air temperature: in respect to pool water temperature, between + 0 K and + 4 K; relative humidity between 40 % and 80 %, preferred < 60 %; air speed in proximity of the users ≤ 0,10 m/s. 5.5.8 Heated surfaces If directly heated surfaces (e.g. heated seats, heated walls, convectors) within the reach of users are installed, their temperatures shall not exceed 40°C. 5.6 Specific areas 5.6.1 Pool surrounds Wherever designed, a pool surround shall grant free flow of users and the avoidance of congestion. For this purpose, the dimensions of the pool surround should be suitably extended corresponding to accesses, exits and features (see Figure 1). In basins or basin areas the surround shall be designed in such a way, that a suitable distance between a possible casualty in water and the nearest position on the pool surround to start a saving/aiding action is granted. This distance shall be < 20 m, otherwise operational measures shall be taken. For swimming pools Types 1 and 2, the minimum width of the pool surrounds shall comply with Table 1, thera-peutic pools excluded. For Type 3, Table 1 gives recommended values. In Figure 1 an example of identification of dimensions of pool surrounds is given. SIST EN 15288-1:2008

G2 Other circulation routes around pool basins over 300 m² 1,5 m 1,5 m 1,5 m a In case the diving installation on the pool surround creates the situation of a passage between two walls, the mini-mum width shall be 1,4 m.
NOTE 1 If the pool surround is designed for extra functions (e. g. activity areas), then the above minimum widths should be increased correspondingly. The pool surround of therapeutic pools shall be designed in accordance to the specific needs of the therapies and of the users they are designed for. Special attention is recommended to the needs: a) for operators to assist the users, also from outside the basin if this is possible (e. g. by pool surround at a level lower than water level); b) for easy rescue of users in difficulty.

EN 15288-1:2008 (E) 14 The pool surround shall also be designed to avoid contamination of the pool water by water flowing on the floor (e. g. rain in outdoor pools; water dripping from the users; floor/gutter washing water; chemicals in wash-ing water). NOTE 2 For deck level pools, this can be achieved if the floor slopes away from the overflow channel and to a drain to waste. It should be possible to divert the overflow channel to a waste-drain to lead the washing water to waste. For skimmer pools, this can be achieved by raising the pool edge (e. g. by a coping). 5.6.2 Pool basin edge 5.6.2.1 Deck level pool basins On deck level pools the pool basin edge shall be marked by a contrasting colour. Where a Finnish overflow is used, its inclination shall be ≤ 10 % towards the pool basin. The surface finish of the submersed/flooded walkable area between the pool basin edge and the overflow channel shall comply with Rating group 24° of EN 13451-1:2001. Deck level pools shall have a gripping system, at least in form of finger hold, at least 15 mm deep on the pool basin edge all around the pool, see EN 13451-1:2001, 4.3.4. 5.6.2.2 Pool basins with freeboard On pool basins with freeboard the pool basin edge shall be distinguishable from the pool surround. The hand-grip shall be located on the pool basin vertical wall or on the pool basin edge, in the area from the water level upwards to + 300 mm. Where handrails are used, they shall comply with EN 13451-1. 5.6.3 Pool basin (pool tank) 5.6.3.1 Pool basin (pool tank) floor Areas with a water depth ≤ 1,35 m are non-swimmer areas. In those areas: a) abrupt changes in depth are not permitted, except for staircases; b) the gradient of the basin floor shall be ≤ 10 %. NOTE Pool basin floor inclination ≤ 6 % is generally recommended, and ≤ 5 % in pool basin areas with a water depth < 0,8 m. c) the slip resistance of the floor shall comply: in water depth < 0,8 m
to Rating group 18° of EN 13451-1:2001; in water depth 0,8 m to 1,35 m to Rating group 12° of EN 13451-1:2001; d) changes in inclination (from horizontal to inclined, or from one inclination to another) shall be marked by a contrasting colour and/or with a floor finish of different tactile quality; e) the surface finish of the basin floor in areas with a water depth ≤ 1,35 m shall not cause discomfort to the users walking on it (e. g. due to the quality of floor tiling, to the edges of the tiles and to the grout). Areas with a water depth > 1,35 m are swimmer areas. SIST EN 15288-1:2008
