Safety guidelines for handling cryo vessels of nitrogen

ADVERTISEMENT

I am looking for any safety guidelines for handling cryogenic vessels of nitrogen indoors and outdoors. I am especially interested in recommendations for area monitors to detect leaks, flow detection devices, etc.

    The Cryogenic Safety Manual is available from the British Cryogenics Council [BCC] in CD format at a price of GBP20 plus post and packing (which would need to check at our post office). We can arrange payment via PayPal if that would be convenient for you. Here is more detail (from the BCC website, http://www.bcryo.org.uk) :

    Cryogenics Safety Manual

    Published by the British Cryogenics Council (1998)

    Since publication of the first edition in 1970, the Cryogenics Safety Manual has become widely accepted as an invaluable reference source for users of cryogenic fluids. The Manual is intended for the guidance of all persons engaged in the production or handling of cryogenic fluids whether on an industrial scale, in research establishments or laboratories.

    The manual is organized into five sections. Chapter one describes the general safety requirements applicable to all cryogenic fluids covered in the Manual. The remaining four sections look at the particular hazards of defined categories of cryogenic fluids. Chapter two discusses the atmospheric gases, nitrogen, oxygen and argon; Chapter three covers the flammable gases, liquefied natural gas, ethylene and ethane; Chapter four is concerned with the problems of handling gaseous and liquid hydrogen; and Chapter five deals with small-scale usage of the rare gases helium, neon, krypton and xenon.

    In publishing the fourth edition of the Cryogenics Safety Manual, the British Cryogenics Council has made minor changes to sections of the text to reflect the introduction of certain new regulations which have come into force since the previous edition and, in addition, increased emphasis on some key aspects of safety. The bibliography has also been expanded to include the most recent literature references.
