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.

---------------------- Page: 10 ----------------------
SIST EN 13451-11:2023
EN 13451-11:2022 (E)
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

Introduction
The structure of safety standards in the field of machinery is as follows:
a) type-A standards (basic standards) giving basic concepts, principles for design, and general aspects
that can be applied to machinery;
b) type-B standards (generic safety standards) dealing with one or more safety aspects or one or more
types of safeguards that can be used across a wide range of machinery:
— type-B1 standards on particular safety aspects (e.g. safety distances, surface temperature,
noise);
— type-B2 standards on safeguards (e.g. two-hand controls, interlocking devices, pressure-
sensitive devices, guards);
c) type-C standards (machinery safety standards) dealing with detailed safety requirements for a
particular machine or group of machines.
This document is a type C standard as stated in EN ISO 12100.
The machinery concerned and the extent to which hazards, hazardous situations and hazardous events
are covered are indicated in the scope of this document.
When provisions of this type C standard are different from those which are stated in type A or B
standards, the provisions of this type C standard take precedence over the provisions of the other
standards, for machines that have been designed and built according to the provisions of this type C
standard.

5 List of significant hazards
Table A.1 shows all the significant hazards, hazardous situations and events identified by risk
assessment as significant for this type of equipment and which require action to eliminate or reduce the
risk. Table A.1 also indicates where they are dealt with in this European Standard.
For a particular floor or bulkhead, a risk assessment should be carried out by the manufacturer to
identify any additional significant hazards so that suitable protective measures can be taken. Additional
hazards are outside the scope of this standard. EN ISO 12100 describes procedures for the identification
and evaluation of hazards.
6 Safety requirements and/or protective measures
6.1 General
Machinery shall comply with the safety requirements and/or protective measures of this clause. In
addition, the machine shall be designed according to the principles of EN ISO 12100 for relevant but not
significant hazards, which are not dealt with by this document.

prEN 13451-11:2016 (E)
Unless specified otherwise, machinery shall comply with the requirements of EN ISO 13850 and
EN ISO 13857.
Hatches for service or cleaning in the moveable pool floor or the moveable bulkhead shall be minimum
of 600 mm for a dry situation, or 800 mm for a wet situation.
The pool design shall ensure good water treatment throughout the pool regarding the moveable floor
and or the moveable bulkhead. The design of water circulation should 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.
Specific hazards and risks related to accessible elements (cables, gears, pulley, lamps, ladders and
products placed into the pool) dedicated to the floor/bulkheads movements/positions shall be assessed
when existing and should be taken into account in the risk assessment.
NOTE It may be necessary to tighten the construction tolerances of the structure and finishes within the
basin in order to meet the tolerances set out within this European Standard.
6.2 Moveable pool floors
6.2.1 General
The gradient of a moveable floor positioned at a water depth ≤ 1 350 mm shall be ≤ 6,6 %.
NOTE It is necessary to pay special attention to the construction tolerances of the structure and/or finishes
within the basin in order to meet the specification of EN 13451-1 within this European Standard.
In presence of a moveable pool floor, the pool water treatment system should be specifically designed
considering possible changes in designation (e.g. a swimmers pool used as non-swimmers pool).
To check the correct water distribution of the complete installation a dye test shall be carried out in
accordance with EN 15288-1 and EN 15288-2 with the moveable floor in 2 positions:
— the lowest operating position; and
— 1/3 of the operating water depth measured from water surface.
Compliance with the dye test is achieved when colouring of the water in the pool tank above the
moveable floor is attained in accordance with the requirements of EN 15288-1 and EN 15288-2 after
the dye is seen to clearly flow through the moveable floor.
NOTE It is likely that the cooperation of the pool builder will be required to achieve a suitable system.
Moveable floors shall allow inspection, cleaning and maintenance of the area underneath the moveable
floor.
6.2.2 Structural integrity
The structural integrity of moveable floors shall be verified using the following independently assessed
criteria:
2
— a vertical uniformly distributed load of 600 N/m ;
2
— a concentrated vertical load of 2 000 N/m over a square area of 1 m2 at any point;
2
— a concentrated vertical load of 2 000 N/m over a square area of 2 m × 2 m focussed in front of the
means of exit and similar areas.

6.2.3 Inadvertent movements
Abnormal movements of a moveable floor (e.g. caused by restoration of the power supply following an
interruption) shall be prevented.
The risks arising from small foreseeable movements during use and maintenance in water shall be
prevented.
6.2.4 Prevention of entrapment
Gaps on the surface of a moveable floor shall be ≤ 8 mm. The gap between the rigid part of a moveable
floor and the pool shall be ≤ 50 mm. When the gap is greater than 8 mm a closure device shall be used to
reduce the gap to ≤ 8 mm wide.
