FOREWORD

This Indian Slandard was adopted by the Bureau of Indian Standards, after the draft finalized by the IndustrialSafely and chemical Hazards Sectional Committee had been approved by the Chemical Division Council.

Hydl ogen is used in the hydrogenation of edible and petroleum oils, in the synthesis of ammonia, methanol,hydrochloric acid, aluminium alkyls, higher alcohols and aldehydes, in the reduction of metal oxides ( such as ironore) and in welding. Liquid hydrogen is an important cryogemc fluid.

Hydrogen is a highly flammable liquid or gas and has a dangerous fire and explosion hazard. Exposure to highlc~cls of hydrogen g_asconcentration can cause suffocation for lack of oxygen. Contact with liquid hydrogen cancause frostbite.

There is no 1S0 Standard on this subject. In the preparation of this Code, considerable assistance has been derivedfrom the following publications:

a) Sax’s Dangerous Properties of Industrial Materials, Volume No. 3, 10th edition, Wiley—IntersciencePublication, John Wiley and Sons. Inc., 2000.
