Liquid Nitrogen Piping Systems for Soil Freezing
Small diameter freeze pipes are installed in the ground, usually vertically in a grid configuration. As a coolant, such as brine or liquid nitrogen, is pumped in a continuous loop into the grid, water in the surrounding soil begins to freeze and eventually forms a wall. The resulting soil wall is roughly the strength of concrete.

Liquid Nitrogen Handling | Environmental Health and Safety
Liquid nitrogen expands 695 times in volume when it vaporizes and has no warning properties such as odor or color. Hence, if sufficient liquid nitrogen is vaporized so as to reduce the oxygen percentage to below 19.5%, there is a risk of oxygen deficiency which may cause unconsciousness. Death may result if oxygen deficiency is extreme.

Liquid Nitrogen Safety Guidelines
Store liquid nitrogen in cylinders or insulated dewar flasks which minimize the loss of product due to boil-off. Store in well-ventilated areas to prevent oxygen deficiency. Never adjust, block, or plug a pressure relief valve. Avoid contact of moisture with storage containers to prevent ice plugs in relief devices.
