FOREWORD

This Indian Standard (Part 3) was adopted by the Bureau of Indian Standards, after the draft finalized by theContinuous Bulk Conveying, Elevating, Hoisting, Aerial Ropeways and Related Equipment SectionalCommittee had been approved by the Mechanical Engineering Division Council.

Amusement parks in India are becoming quite common and people visit these parks quite often. In order toensure their safety in amusement parks or while enjoying the rides, an attempt has been made to stipulate safetyin the form of a National Code. It is hoped that organizers of amusement parks, manufacturers of rides wouldmake use of these codes to ensure overall safety of human beings and equipment at such places.

The code of recommended practice for amusement rides safety is being brought out in six parts. This standard ~covers the requirements which needs to be considered during design, manufacture and erection of amusement t

rides. Other parts in this series are as follows: ii’1

(Part 1) General informationj

(Part 2) Safety requirements /

(Part 4) Selection, training and supervision of operators

(Part 5) Operation and maintenance procedures

(Part 6) Performance tests

In preparation of this standard, assistance has been taken from ASTM standards available on amusement ridesor devices. Considerable assistance has also been derived from the following Indian Standards:
