SAFETY PRECAUTIONS
IT IS IMPORTANT TO READ THIS SAFETY NOTICE PRIOR TO
OPERATING ANY EQUIPMENT
First Aid
IF IN DOUBT, SEEK IMMEDIATE MEDICAL
ATTENTION. If any quantity of liquid nitrogen comes
into contact with the skin or eyes, immediately flood that
area of the body with large quantities of unheated water,
apply cold compresses and seek medical attention. If the
skin is blistered or there is any possibility that eyes have
been affected, the patient should be taken immediately to
a doctor or hospital for treatment.
Safety
Failure to comply with these instructions could result
in personal injury
™ Operating the system in a manner not specified within in this manual or
under conditions outside of the specifications, see
Appendix A , may result
in the protection offered by the equipment being impaired.
™ Avoid nitrogen build up: anywhere liquid nitrogen is used must be well
ventilated to reduce the risk of nitrogen build up. Small volumes of liquid
nitrogen convert to very large volumes of gas. This can result in
drowsiness, or in extreme cases, asphyxiation.
™ When liquid nitrogen is used in confined spaces, oxygen-deficiency alarms
must be installed. Guidance on ventilation requirements are given in
BCGA Code of Practice CP30, The safe use of liquid nitrogen dewars up to
50 litres.
™ When there is a risk of reduced or insufficient ventilation when a room is
unoccupied, then alarms to indicate oxygen deficiency must be installed
and positioned outside of the room so that operators are aware of the
hazard before entering. The operational status of such an alarm should also
be visible from outside the room.
