storage guide
EXTENSIVE advice on the hazards which can be associated with liquid carbon dioxide is assembled in a guidance note on its storage and use published by the Health and Safety Executive.
The dangers from this widely used industrial material include intense cold, suffocation and poisoning.
The liquefied gas may be stored in vessels ranging iron' two to 250 tonnes capacity. After refrigeration and very high pressurisation the required gas is drawn off by a vaporiser.
The guidance note contains information on the principal hazards arising from bulk storage of the liquid. It gives general advice on precautionary measures and control techniques which experience has shown to be appiopriate.
Also covered are recommended exposure limits, protection of operators and road tanker delivery drivers, siting of the vessels, inspection and maintenance, display of operating instructions, and action to be taken in emergencies.
Bulk storage and use of liquid carbon dioxide: hazards and procedures (CS 9) is available from HM Stationery Office or booksellers, price £2.25. ISBN 0 11 8835130.
