Microstat He Manual

3.12 Fire

Atmospheric oxygen can condense on cryogenicaly-cooled objects. Oxygen can cause flammable substances to

ignite in the presence of heat or arcing, risking severe injury.

Rooms where cryogenic liquids are being handled must be designated as no smoking areas. While liquid helium and nitrogen do not sup-

port combustion, their low temperature can cause oxygen from the air to condense on surfaces and may increase the oxygen concentration

in these areas.

3.13 Safety equipment

The following items are recommended for safe operation of any system:

• Personal protective equipment, including thermally insulated gloves, face protection and protective footwear.

• Hazard warning signs, barriers or controlled entry systems to ensure that personnel approaching the system are aware of the

potential hazards. This precaution is especially important if you system includes a superconducting magnet.

3.14 Maintenance

Observe the necessary maintenance schedule for the system. Consult Oxford Instruments if you are unsure about

the required procedures.
