Liquid Nitrogen 

WARNING 

 

IF LIQUID NITROGEN FACILITIES ARE NOT INSTALLED, OPERATED AND MAINTAINED 

CORRECTLY, DANGEROUS SITUATIONS CAN RESULT. THESE INTRODUCE RISKS OF: 

 

A)

 

HAZARDOUS PRESSURE BUILD-UP CAUSED BY THE BOIL-OFF OF LIQUID 

NITROGEN, WHICH CAN RESULT IN AN EXPLOSION. 

 

B) 

PERSONAL INJURY FROM TOUCHING PIPEWORK OR OTHER SYSTEM 

COMPONENTS CARRYING LIQUID NITROGEN. THIS RISK CAN REMAIN EVEN 

AFTER VENTING THE CHAMBER. 

 

C)  ASPHYXIATION CAUSED BY THE BOILED-OFF LIQUID NITROGEN REPLACING 

OXYGEN IN THE SYSTEM ENVIRONMENT. 

 

 

7.1

 

Mandatory Requirements for Liquid Nitrogen systems 

•

 

Ensure that the Liquid Nitrogen installation is carried out in accordance with local 

safety regulations. This includes the following: 

 

(a) 

No part of the Liquid Nitrogen circuit can become blocked with ice or 

other contaminants. 

 

(b) 

Adequate precautions, e.g. pressure relief valves, are fitted to prevent 

hazardous pressure build-up from boil-off of the Liquid Nitrogen. 

 

(c) 

All system components carrying Liquid Nitrogen are adequately 

insulated, and covered to prevent personnel touching exposed 

components. 

 

•

 

Ensure that the installation is inspected by a Specialist to confirm that it is safe to 

use. Inspections must be carried out before the system is commissioned and at 

regular intervals throughout its life. 

 

•

 

Pipework from the Dewar to the system must be adequately insulated and 

connected to the system via a 

3

/

8

” Swagelok connector.
