Precautions with regards to the equipment:
Warning:
nitrogen is liquid at extremely low temperatures and is stored in a double-walled tank. A high vacuum
between the walls ensures good thermal insulation.
This equipment, especially mobile storage tanks, must be handled with care.
•
Avoid impacts. Never lay a cryogenic container on its side.
•
Do not expose containers to excessive temperatures.
•
Treat valves with care (operate gently, do not dismantle or lubricate valves).
•
All equipment used must be in good condition and designed for use at the intended temperature and
pressure.
•
Mobile equipment must be sheltered from inclement weather. Open-necked containers must be fitted with
stoppers to avoid the neck becoming blocked by cryopumping of ambient humidity.
•
Use suitable connection hoses; never use intermediate couplings.
•
Monitor the pressure of closed containers and check safety equipment (pressure relief valve).
•
Regulations apply to the transportation of recipients.
Users of the equipment, who are fully aware of the conditions of use and thus best placed to monitor the equipment,
are solely responsible for proper use.
