CAUTION

Nitrogen cylinders are pressurized containers. The pressure in the cylinder can exceed

2000 psi. A nitrogen pressure regulator should be used at all times when nitrogen is used

for leak check or purge operations. Nitrogen is an inert gas. However, it also presents

danger as a suffocant and, therefore, must also be discharged in a ventilated location.
