FOREWORD

This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the Fire Safety
Sectional Committee had been approved by the Civil Engineering Division Council:

The blanket is intended for use in fire fighting operations for protection of the operator and for smothering and
extinguishing fire in its early stages.

For the purpose of deciding whether a particular requirement of this standard is complied with, the final value
observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2: 1960
‘Rules for rounding off numerical values (revised)’. The number of significant places retained in the rounded off
value should be the same as that of the specified value in this standard.
