2 TERMINOLOGY

For the purpose of this code, the following definitionsshall apply.

2.1 “Water Slide — Piece of equipment with an inclinedsliding surface, down which the user descends bysliding usually under the influence of gravity and withwater as the friction-reducing medium, either freelyor with the use of ride enhancement devices, if sodesigned.

2.2 Platform — Area providing access to the startsection.

2.3 Start Section — Area at which the user entersthe slide proper.

2.4 Slide Proper — Area intended for sliding.

2.5 Final Part — Part of the slide proper with andownward inclination of less than 5 percent, designedto prepare the user for landing.

2.6 Catch Unit —Integral part of a water slide, notpart of the slide proper, which brings the rider to ahalt on the sliding surface.

2.7 Splash Down Area — Either a specific pool or an

area which is part of a general purpose pool, in whichthe rider is brought to a halt in the water.

2.8 Drop — Length of the slide proper, titled withan inclination greater than those of adjacent sections.

2.9 Tube —Closed section, not necessarily circularin cross-section, of a water slide, with a fullyutilizablesliding surface.

2.10 Cover — Device. to enclose an open slide, notintended for sliding.

2.11 Riser — Extension for the slide proper, intendedfor sliding.

2.12 Wave Screen — Device, placed within theclearance zone, to centroi spilling water.

2.13 Ride Enhancement Device — Device to slideon or in, designed for a particular water slide.

2.14 Guardrail — A device to restrict users fromfalling over, under or through it.

2.15 Average [inclination — Inclination calculatedby the following formula:

hx 100.Y = percent

I

where

h = height between start section and beginningof final part, in metres; and

1 = actual length of the slide proper excludingthe final part, in metres.

2.16 Clearance Zone — Space around the slideproper, free from obstacles.

5.6 Stationery Persohs

The loads of stationery persons shall only be takenin to consideration where the inclination is lessthan 20 percent. In this case the load shall be takenas 0.8 kN/m for Type 1 to Type 2 and 1.5 kN/m forType 3 to Type 6.

For Type 7 the load for stationery persons shall beincluded in the load of the sliding persons which”hasto be calculated over the complete sliding surface.

5.7 Wind Load

6 SAFETY REQUIREMENTS

6.1 General

6.1.1 Water slides installed in the park should be treatedas structures and attention is drawn to the statutoryrequirements with regard to means of access and meansof support.

6.1.2 Various risks can be involved in using waterslide, for example, ejection from the slide, impacts, falls,burns, entrapment. Following requirements shall becomplied to reduce such risks and to be applied asappropriate:

a) Material and components sha[l not causeadditional hazards taking into account theswimming pool environment.

b) If special feature has been incorporated inthe design, for example, special water etiects,then the user shall be informed of specialfeature and if any special precautions haveto be observed.

‘1-J

1S 15492( Part 2 ): ~004

c) It is a general safety recommendation thatthe user should remain in contact with theslide proper throughout its length unless madeaware prior -to use of the possibility ofbecoming involuntarily airborne.

6.2 Surfaces

6.2.1 Surfaces in reach by staff and the public shouldbe protected or constructed in such a way as to preventinjuries. The surface within the clearance zone andshall have no apertures except those for water or specificfeatures ( see 7.5).

6.2.2 Surface of the Slide Proper

The surface of the slide proper shall forma smooth,continuous surface, free from irregularities; a differencein level is permitted where two elements are joinedtogether but this shalInot be against the sliding directionand should not cause discomfort to the rider. Thissurface includes the returns on the top edges.

6.3 Corners and Edges

Corners and edges within the clearance zone shail berounded to a radius of at least 3 mm, and edges ofcuts and holes should be suitably protected.

6.5.4 Except for Type 1, water slides shall have acrossbar situated 800 mm to 1 100 mm, above thesurface of the slide between the start section and theslide proper. This is to prevent.the user entering theslide standing up and to aid the user sitting downand sliding in accordance with the instructions.

6.6 Slide Proper

The top edges of both outer sides of a slide shallbe made in such a way that in normal use the usercannot touch or reach the outer parts of the Slide. Theindividual components of the slide proper shall bearranged ‘or designed in such a way that slider iscontained at all times within slide and that his naturalprogression is safe.

6.6.1 Maximum Acceleration on a Sliding Person

The acceleration and its duration can have an influenceon the users and the film of water on which they travel.In accordance with current experience accelerationand its duration should conform to Table 2.

6.11.3 Controlling Systetn

There shall be means of ensuring that interferencewith the water flow rate by unauthorized personis eliminated. It is also recommended that an alarmdevice be installed which activates in the event ofmalfunction of water flow controls.

6.12 Interference Between Users

6.12.1 The slide shall be designed and/or installedand equipped in such a way that interferencebetween users ( not-sliding in a chain ) is prevented.Interference between users can be caused byinappropriate spacing at the start and/or by significantdifferences in speed of the users caused by differentsliding positions.
