Overview

EN 13451-11:2022 (CEN) specifies additional safety requirements and test methods for moveable pool floors and moveable bulkheads installed in public swimming pools. It applies to the design, construction and verification of these devices for classified pools (see EN 15288-1 / EN 15288-2) and addresses significant hazards listed in Annex A. This part of the EN 13451 series takes precedence over EN 13451-1 where requirements differ. It does not cover equipment intended to move people into or out of a pool and only applies to equipment manufactured after the standard’s publication.

Key topics and technical requirements

• Scope and classification
  • Defines moveable pool floors and bulkheads and classifies them (Type 1: buoyancy-bearing; Type 2: drive-supported).
• Design and structural integrity
  • Requirements for load-bearing design, recessed ledges/steps and construction tolerances to meet entrapment limits.
• Prevention of entrapment and pinch points
  • Measures for closure devices and perimeter gaps; testing procedures for flexible closure devices are specified (Clause 6).
• Movement and operational safety
  • Requirements to prevent hazards during movement (abnormal movement, interference with circulation systems); includes the new requirement that no person shall be on the floor or bulkhead while moving.
• Slip resistance and fall prevention
  • Surface friction and edge protection to reduce slip and falling-off hazards.
• Access, maintenance and emergency provisions
  • Minimum hatch sizes for service/cleaning (600 mm; 800 mm if divers with equipment require access), tamper-proof power isolation and securing against inadvertent movement, requirement for at least one survival area or escape opening.
• Information and documentation
  • Manufacturer instructions, user manual and safety information (Clause 7).
• Test methods and verification
  • Test methods for closure devices and other verification methods to demonstrate compliance.

Practical applications and who uses it

• Manufacturers of moveable pool floors and moveable bulkheads use EN 13451-11 to design safe, compliant products for public pools.
• Pool operators and facility designers reference the standard when specifying equipment, planning circulation systems and maintenance access.
• Safety regulators and conformity assessors use it for market surveillance and to verify equipment meets CEN safety requirements.
• Maintenance and service providers use the standard to follow required locking, isolation and inspection procedures.

5 Safety requirements
5.1 General
Moveable floors and moveable bulkheads shall comply with the safety requirements of this clause.
Hatches for service or cleaning in the moveable pool floor or the moveable bulkhead shall have a
minimum diameter of 600 mm. If divers with their equipment need access, a minimum diameter of
800 mm is required. Square and rectangular shaped hatches are allowed, as long the main dimensions
are considered.
NOTE 1 The minimum number of hatches can depend on the pools size.
The pool design shall ensure good water treatment throughout the pool with the moveable floor and or
the moveable bulkhead. The design of water circulation shall take into account the need of equal flow in
different pool areas when only a part of the complete pool is to be fitted with a moveable floor or
bulkhead.
NOTE 2 It can be necessary to tighten the construction tolerances of the structure and finishes within the basin
in order to meet the entrapment requirements according to this document.
During maintenance and inspection works performed in the area underneath the equipment:
a) the operation of the equipment shall be prevented by tamper proof systems (power isolator lockable
in the “off” position with a removable key);
b) the equipment shall be secured against inadvertent movements.
The drive system shall only be accessible for maintenance and inspection. In all other cases, the
accessibility shall be prevented. The access to the drive system shall only be possible for qualified
persons, based on the manufacturer's risk assessment.
When applicable, the regulations for underwater working shall be complied with.
At least one survival area or one escape opening shall be provided in case the securing system fails.
NOTE 3 When the pool is fitted with a perimeter corridor, it is advisable to install an underwater window to
allow visual control of the area underneath the equipment.
Where the manufacturer requires a specific supporting system to support the equipment in case the pool
is empty:
c) it shall always be used in accordance with manufacturer’s instructions;
d) if the system is designed to bear only the dead load of the equipment, access to its surface shall always
be prevented.
Control systems of moveable floors and bulkheads shall be designed and constructed in such a way as to
prevent hazardous situations while moving the moveable floor or bulkhead. They shall be designed and
constructed in such a way that:
e) a fault in the hardware or the software of the control system causes an emergency stop of the
movement;
f) the moveable floor or bulkhead does not start unexpectedly;
g) a stop command leeds reliably to a stop of the movement.
For cable-less control, an automatic stop shall be activated when correct control signals are not received.
Control devices shall be:
h) clearly visible and identifiable;
i) positioned in such a way as to be safely operated without hesitation or loss of time and without
ambiguity, and give full view of the pool with the moveable floor or bulkhead;
j) designed in such a way that the movement of the control device is consistent with its effect.
Where there is more than one control position, the control system shall be designed in such a way that
the use of one of them precludes the use of the others, except for stop controls and emergency stops.
When movable floor or bulkhead has two or more control devices, each control device shall be equipped
with all the required control functions.
If a movable floor stops in a water depth not specified by the manufacturer (e.g. by a power supply
failure), the pool shall be closed for public use and a warning shall be given to the operator.
Moveable floors and bulkheads shall be designed and constructed in such a way that hazardous materials
