4.4 Hair entrapment
Wall and floor water outlets shall pass the hair entrapment test in accordance with 5.3.
4.5 Slip resistance of grilles
Slip resistance of any walkable grilles shall comply with the requirements in accordance with
EN 13451-1:2011+A1:2016, Table 1.
4.6 Risk of suction entrapment
4.6.1 General
Suction systems either with suction pumps or gravity tanks shall be designed and installed so as to
reduce the potential for entrapment of the user.
Water speed at outlets shall be ≤ 0,5 m/s.
NOTE 1 There is a direct correlation between the risk of suction and hair entrapment and high water speeds
through outlets. It is advised to keep water speed as low as possible, taking into consideration hydraulic technical
requirements (e.g. avoid stagnation).
Valves fitted on pipes connecting suction outlet(s) to pump(s) shall not be accessible to unauthorized
people (users and inexperienced staff).
The water speed is obtained with the following formula:
Q
v=
A
Where:
— v is the water speed calculated through any openings of the suction grille, in metres per second;
— Q is the flow rate measured in the pipe connected to the suction grille, in cubic metres per second;
— A is the total free openings surface of the suction device grille, provided by the manufacturer of the
suction device grille, in square metres.
NOTE 2 It is advised to take into account a safety factor for debris and construction tolerances when
considering the free opening surface of the grille.
Additionally at least one of the either a) or b) shall be met:
a) in case of suction outlet systems with only one grille, suction outlet shall be designed in such a way
that:
2
1) only single grilles with a surface of the area circumscribed to the suction openings ≥ 1 m (see
Figure 2) are allowed, or
2) A rectangular template representing an adult torso sized 65,5 cm × 36,0 cm, with 4x50mm
radius corners shall not cover more than 50 % of the free projected suction surface, with any
orientation of the template. In that case, the water speed at the remaining free opening surface
shall not exceed 0,8 m/s (see Figure 1).

---------------------- Page: 11 ----------------------
SIST EN 13451-3:2022
EN 13451-3:2022 (E)
b) when more than one suction outlet is connected to a single pump (or single suction group) or
gravity feed tank, suction outlets shall be designed in such a way that:
1) the distance between the nearest points of the perimeters of the devices is ≥ 2 m, and;
2) at least 50 % of the open cross section, connected to the same pump (or single suction group)
remains not covered when applying a rectangular template representing an adult torso sized
65,5 cm x 36,0 cm, with 4 corners of 50 mm radius on any suction outlet (see Figure 1), and;
3) if any one of the suction outlet becomes blocked, the entire hydraulic system connected to the
remaining suction outlets shall be designed to accommodate 100 % of the nominal flow rate. In
this case the water speed at the remaining outlets shall not exceed 0,8 m/s. The flow and the
pressure loss in the hydraulic system shall be taken into account.
NOTE 3 This requirement is to prevent a suction entrapment risk from being created in the hydraulic
system in the event one of the outlets gets blocked.

outlet (e.g. by means of valves), then both requirements a) and b) shall be met.
Suction connexion points for cleaners shall not be taken into account in the total number of suction
outlets.
Figure 2 — Identification of the area circumscribed to the suction openings
When retrofitting existing installations that have a single suction outlet which does not comply with the
requirements of this clause, then the following actions are required:
— the existing suction outlet shall be retrofitted with a grille conforming to a), or;
— one or more additional suction outlets shall be provided as in b) .
In addition to the requirements in a) or b), a vacuum release system may be provided.
NOTE 4 Vacuum release systems are not considered “fail safe” systems as there is no known suction vacuum
release system that will completely protect against all suction entrapment hazards.
Safety requirements a) and b) are not applicable to:
— skimmers, because they are vented (see 4.6.3) and partly above the water level;
— integrated swim jet systems, because the users are pushed away from the outlet by the action of the
inlet.
— suction connexion points for cleaning equipment as they shall not be used or open/uncovered
when bathers are in the pool.
NOTE 5 It is advised to install at the deck level an accessible general emergency switch for the pumps.

Where a feature incorporates a change of depth (e.g. a submerged step) it shall be marked by
contrasting colours.
4.7.2 Introduction of water and/or air from the floor
Features incorporating the introduction of water and/or air under pressure from the swimming pool
floor shall not be installed in depths of less than 700 mm unless:
a) the vertical water speed is ≤ 2 m/s (see 4.3); and
b) the dynamic pressure in the system before the inlet is ≤ 30 kPa.
NOTE These requirements do not apply to balneotherapy equipment such as seats, benches and lounges.
For water speed test see Annex A.
4.7.3 Influence of features on the users
The introduction of water and/or air under pressure shall not compromise the safety of the users (e.g.
by impact against obstacles or the pool wall).
Features shall not operate at full pressure immediately; they shall build up to their full pressure over a
period of time, sufficient for the users to become aware.
4.8 Additional requirements for specific leisure features
4.8.1 Stream channels
4.8.1.1 General
The speed of the water and the path of stream shall not compromise the safety of a user entering or

The water speed is obtained with the following formula:
Q
v=
A
Where:
— v is the water speed calculated through any openings of the suction grille, in metre per second;
— Q is the flow rate measured in the pipe connected to the suction grille, in cubic metre per second;
— A is the total free openings surface of the suction device grille, provided by the manufacturer of the
suction device grille, in square metre.
NOTE 2 It is advised to take into account a safety factor for debris and construction tolerances when
considering the free opening surface of the grille.
Additionally at least one of the either a) or b) shall be met:
a) in case of suction outlet systems with only one grille, suction outlet shall be designed in such a way
that:
2
— only single grilles with a surface of the area circumscribed to the suction openings ≥ 1 m (see
Figure 2) are allowed, or
— A rectangular template representing an adult torso sized 65,5 x 36,0cm, with 4x50mm radius
corners shall not cover more than 50 % of the free projected suction surface. In that case, the water
speed at the remaining free opening surface shall not exceed 0,8 m/s.
b) when more than one suction outlet is connected to a single pump (or single suction group), suction
outlets shall be designed in such a way that :
1) the distance between the nearest points of the perimeters of the devices is ≥ 2 m, and;
2) at least 50 % of the free projected cumulated suction surface, connected to the same pump (or
single suction group) remains not covered when applying a rectangular template representing
an adult torso sized 65,5 x 36cm, with 4x50mm radius corners on any suction outlet (see
Figure 1); and;

3) if any one of the suction outlet becomes blocked, the entire hydraulic system connected to the
remaining suction outlets shall be designed to accommodate 100 % of the nominal flow rate. In
this case the water speed at the remaining outlets shall not exceed 0,8 m/s,
NOTE 3 This requirement is to prevent a vacuum from being created in the hydraulic system in the event
one of the outlets gets blocked.
If the outlet system is designed to operate either with multiple suction outlets or with a single suction
outlet (e.g. by means of valves), then both requirements a) and b) shall be met.
Suction connexion points for cleaners shall not be taken into account in the total number of suction
outlets.

NOTE 4 It is advised to determine frequency of testing by risk assessment.
When retrofitting existing installations that have a single suction outlet which does not comply with the
requirements of this clause, then the following actions are required:
— the existing suction outlet shall be retrofitted with a grille conforming to a), or;
— one or more additional suction outlets shall be provided as in b) .
In addition to the requirements in a) or b), a vacuum release system may be provided.
NOTE 5 These devices/systems are not considered “fail safe” systems as there is no known suction vacuum
release system that will completely protect against all outlet entrapment hazards. Presenting Vacuum Release
Systems as “fail safe” systems would promote a false sense of security among the users of these devices/systems.
Safety requirements a) to b) are not applicable to:
— skimmers, because they are vented (see 4.6.3) and partly above the water level;
— integrated swim jet systems, because the users are pushed away from the outlet by the action of the
inlet.
— suction connexion points for cleaners as they shall not be used when bathers are in the pool.
NOTE 6 It is advised to install at the deck an accessible general emergency switch for the pumps level.
4.6.2 Sump
4.6.2.1 Manufactured sump for floor and wall water outlets
The combination of the manufactured sump and its corresponding grille shall be designed to provide a
uniform water speed distribution through the grille and avoid vortex effect.
This combination shall fulfil the safety requirements of 4.4 (hair entrapment) and 4.6.1 (suction
entrapment)
4.6.2.2 Field build sumps for floor and wall water outlets
For field built sump using a prefabricated grille, the grille manufacturer shall provide dimensional
instructions for the implementation of the sump to ensure that the assemblies fulfil the safety
requirements of 4.4 (hair entrapment) and 4.6.1 (suction entrapment).
The sump shall be designed to provide a uniform water speed distribution and avoid vortex effect.
