ICS 13.340.99                         CHD 08

New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 7) which is identical with ISO 14567 : 1999 ‘Personal protective equipment for protection against falls from a height — Single-point anchor devices’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Occupational Safety and Health Sectional Committee and approval of the Chemical Division Council.

In cases where the hazard of falling from a height exists and where, for technical reasons or for work of very shortduration, safe access cannot be otherwise provided, it is necessary to consider the use of personal fall-arrestsystems (PFAS). Such use should never be improvised and its adoption should be specifically provided for in theappropriate formal provisions for safety in the work place.

IS 3521 was originally published in 1964 and it covered industrial safety belts and harnesses only. IS 3521 is now being revised to harmonize with latest ISO standards and it has been split into several parts to cover all components of a fall arrest system. IS 3521 is being revised as IS 3521 (Part 1) covering full body harness (FBH) while this standard is IS 3521 (Part 7) which covers single point anchor devices.

Part 1 Full body harness fourth revision

Part 2 Lanyards and energy absorbers

Part 3 Self-retracting lifelines

Part 4 Vertical rails and vertical lifelines incorporating a sliding-type fall arrester

Part 5 Connectors with self-closing and self-locking gates

Part 6 System performance tests

Part 8 Flexible horizontal lifeline systems

Part 9 Descending devices

The text of the ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘This Indian Standard’.

b) Comma (,) has been used as a decimal marker, while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
