The extreme cold will cause flesh to stick fast and potentially tear on withdrawal. If there is any difficulty in operating the container valve or container connections discontinue use and contact the vendor. Do not remove or interchange connections. Use only the properly assigned connections. Do not use adapters. Use only transfer lines and equipment designed for use with cryogenic liquids. Some elastomers and metals, such as carbon steel, may become brittle at extremely low temperatures and may easily fracture.
These materials must be avoided in cryogenic service. On gas withdrawal systems use check valves or other protective apparatus to prevent reverse flow in the containers. On liquid systems pressure relief devices must be used in lines where there is the potential to trap liquid between valves. It is recommended that all vents be piped to the exterior of the building. Liquid containers should not be left open to the atmosphere for extended periods.
Keep all valves closed and outlet caps in place when not in use. If restriction results from freezing moisture or foreign material present in openings and vents contact the vendor for instructions.
Restrictions and blockages may result in dangerous over-pressurization. Do not attempt to remove the restriction without proper instructions. If possible move the cylinder to a remote location. Use only manufacturer approved containers e. Laboratory personnel must use extreme caution when preserving samples in liquid nitrogen. Liquid nitrogen storage consists of a liquid phase and a gaseous phase. If cyrovials are immersed in the liquid phase, liquid nitrogen can enter the closed cyrovials during storage.
The cryovial may then explode when it is removed from storage due to the vaporization and expansion expansion ratio of the liquid nitrogen inside the cryovial. Do not store cryovials in the liquid phase of liquid nitrogen unless specifically approved by the manufacturer for liquid phase storage. If storage in the liquid nitrogen liquid phase is required use only manufacturer approved cryovials specifically designed for liquid phase storage. Use gaseous phase approved cyrovials that are then sealed in an outer protective envelope designed for use in liquid nitrogen.
The risk of explosion of cryovials stored in the liquid phase can be reduced by moving cryovials to the gaseous phase in the liquid nitrogen container for at least 24 hours prior to removal. Eyes are most sensitive to the extreme cold of liquid nitrogen and its vapors.
In addition, safety shoes are recommended for those involved with the handling of liquid nitrogen containers. In the event a person is injured by liquid nitrogen, the following first aid treatment should be given pending the care of a physician ONLY if there is no risk to you.

As soon as practical place the affected area in a warm water bath that has a temperature not in excess of o F 40o C. Never use dry heat. Frozen tissue is painless and appears waxy with a possible yellow color. It will become swollen, painful, and prone to infection when thawed.
If the frozen part of the body has been thawed, cover the area with a dry sterile dressing with a large bulky protective covering, pending medical care. In case of massive exposure, remove clothing while showering the victim with warm water.
Do not use hot water. Call a physician immediately. If the eyes are exposed to the extreme cold of the liquid nitrogen or its vapors, immediately warm the frostbite area with warm water not exceeding o F 40o C and seek immediate medical attention. Take a copy of the MSDS to the physician. People suffering from lack of oxygen should be moved to fresh air. If the victim is not breathing, administer artificial respiration. Drug cartel and narco-terrorist operations have rapidly expanded in the region in the past eight years.
Following a boom of liquid cocaine trafficking, which originated in South America in , these groups have developed more complex ways to transport it. To make cocaine from coca leaves, drug cartels use ethanol, acetone, gasoline, ether, chloroform, sulphuric acid, kerosene, lime, hydrochloric acid, among other chemicals. One person can carry up to one kilo of liquid cocaine in his or her body. Other ways of transporting the drug is by impregnating clothes.
