corrigendum August 2008

Playground equipment

and surfacing —

Part 5: Additional specific safety

requirements and test methods for

carousels

This British Standard was

published under the authority

of the Standards Policy and

Operators and providers are advised that equipment conforming

to EN 1176 require regular maintenance Guidance on this and appropriate inspection, maintenance and operation schedules are contained within

BS EN 1176-7:2008

National standards have been published by BSI on children’s playground equipment since BS 3178 was first issued in 1959, this standard concentrated

on specifications for specific types of equipment It was replaced in 1979

by BS 5696 which switched focus to a design and safety approach

With the increasing introduction of overseas equipment BSI led the way by calling for a European Standard to address the conflicting safety advice and standards from other countries This was published in 1999 as BS EN 1176 and further focused on the safety of playground equipment

All standards published by BSI are regularly assessed and this revision is part

of the process, it takes into account new design concepts and the operating experience available to the standards committees

It is advised that the previous version of BS EN 1176 will not be withdrawn until 31 May 2009 to give manufacturers time to amend their product lines Playground equipment not complying with this revision should not

automatically be considered as being unsafe or to require replacement A risk assessment by competent persons should be used to determine what action, if any, is necessary Manufacturers and Inspectors of the Register of Play Inspectors International (RPII) are amongst those that will be able to assist in this

A list of organizations represented on this committee can be obtained on request to its secretary

This publication does not purport to include all the necessary provisions of a contract Users are responsible for its correct application

Compliance with a British Standard cannot confer immunity from legal obligations

hands or feet) transmitted to drive wheels (see Figure 4)

Key

view on X (enlarged)

Figure 4 — Example of carousel type D (track-driven carousel)

3.6

carousel type E

giant revolving disks

giant revolving disks are carousels having an inclined axis (as specified in 4.5) whose user stations are not

clearly definable (see Figure 5)

NOTE They can be set in rotation by the user's physical strength up to the running speed of the users and taking into

account gravity

Figure 5 — Example of carousel type E (giant revolving disk) 3.7

user station

seat or platform and/or handholds on a carousel that allow the user to stay on or to propel the carousel

NOTE The user stations are either rigidly connected to the supporting structure or are mounted on it so as to be

diameter of the circle described by the construction element farthest away from the centre of the rotational

axis where the carousel is in use

3.11

carousel axis

central shaft on which the supporting structure is pivot-mounted and that is rigidly connected to the

founda-tions or installation components

NOTE The carousel axis can also be a theoretical line when the carousel structure is mounted on a circular track

4 Safety requirements

4.1 General

Carousels shall conform to EN 1176-1 unless otherwise specified in this part of EN 1176

NOTE Hand rails provided on carousels need not meet the height requirements given in EN 1176-1:2008, 4.2.4.2

4.2 Free height of fall and impact area

Except for carousels of type C, the free height of fall shall be not more than 1 000 mm at any point

For type C carousels, the free height of fall shall be measured from the grip position minus 1 500 mm to the surface below (see also 5.3.4)

The impact area around the carousel shall have critical fall height of at least 1 000 mm

4.3 Free space/falling space

NOTE See Figure 6

The principal risk connected to carousels is that of the centrifugal force which results from the rotation In viating from the requirements for free space (see EN 1176-1), for carousels the free space and falling space are the same

de-NOTE This is substantiated by the fact that the centrifugal force which is generated by the carousel often leads to the user leaving the carousel in an uncontrolled movement Therefore, attention should be paid to there being no obstacles in the falling space

Unless otherwise specified, the free space/falling space shall be as follows:

a) to the side of the carousel, at least 2 000 mm; and

b) for the free space above the carousel, at least 2 000 mm

When carousels are placed near other items of playground equipment, the impact area of the carousel and the impact area of the other playground equipment shall not overlap

4.4 User stations

In addition to the requirements in EN 1176-1 regarding entrapment of body parts of users (e.g arms and legs), care should also be taken regarding entrapment of clothing (e.g jackets, body warmers) that could re-strain users when getting off the carousel

User stations of type A carousels that are supplied with seats shall be equipped with a backrest or hand grip

NOTE Carousels without mechanical advantage cannot reach 5 m/s as this is above the normal running speed of a child

4.7 Grip handles

If user stations are designed to include a hand grip they shall conform to EN 1176-1:2008, 4.2.4.6

4.8 Load capacity and stability

The number of users on a carousel shall be the highest number of user stations identified, or calculated in cordance with EN 1176-1:2008, A.2.6.2

ac-For carousels the following load cases shall be considered:

a) where the load Ftot is evenly distributed over the entire carousel; and

b) where the load Ftot (½ Lpr or ½ Apr) is equally distributed over one-half of the carousel

5 Type specific requirements

5.1 Carousel type A (rotating chairs)

The carousel diameter d shall not be more than 2 000 mm (see Figure 6)

The ground clearance H2 shall not be less than 400 mm (see Figure 6)

There shall be at least three user stations equally spaced on the periphery

All components that move about the carousel axis shall be free from burrs and shall be rounded with a radius

of at least 5 mm

5.2 Carousel type B (classic carousel)

5.2.1 General

For this type of carousel there is a danger of entrapment under the carousel platform An additional danger is that the construction of the carousel has parts, such as bolts and superstructure, that protrude into the space between the underside of the carousel platform and the ground

To prevent risks occurring from such hazards, carousels shall conform to 5.2.2 to 5.2.6

The carousel shall comprise a circular enclosed solid platform with constituent elements that revolve in the same direction

Superstructures shall not overlap the outside edge of the platform

Carousels type B that include a stationary central hand-wheel shall be constructed to avoid any entrapment, e.g the central column and the hand wheel shall be fully enclosed without any protruding parts

The carousel shall either:

⎯ have a platform flush with the ground and conform to 5.2.2, or

⎯ have a platform, the underside of which shall have a ground clearance of at least 60 mm

5.2.2 Rotating platform flush to the ground

The vertical gap between the ground and the outer edge of the platform shall be less than 8 mm when ured in one direction (see Figure 7)

meas-The vertical displacement between the top surface of the platform and the ground shall not be greater than

If the ground clearance is between 60 mm and 110 mm (see Figure 8a), it shall be continued for at least

300 mm towards the axis and for the remaining surface shall be at least 60 mm The underside of the rotating platform shall be smooth within the first 500 mm towards the axis

Where the distance between the ground and the underside of the platform is between 110 mm and 400 mm, the rotating platform shall either: conform to 5.2.4, or to 5.2.6

For ground clearances of greater than 400 mm (as shown in Figure 8b) and 8c)) the underside of the rotating
