In areas where dewars need to be transported between floors via lift, a clear procedure must be in place and available to all staff. Oxygen is nontoxic. You can already see that the plot is good. 7727-37-9 UN No. - Gases such as nitrogen or helium can displace air creating an oxygen-deficient atmosphere. Asphyxiation One of the main dangers associated with liquid nitrogen is the risk of asphyxiation when used or stored in poorly ventilated areas. Although nitrogen is nontoxic and inert, it can act as a simple asphyxiant by displacing the oxygen in air to levels below that required to support life. Apply non-stick dressing and seek medical attention.

You can already see that the plot is good. 7727-37-9 UN No. - Gases such as nitrogen or helium can displace air creating an oxygen-deficient atmosphere. Asphyxiation One of the main dangers associated with liquid nitrogen is the risk of asphyxiation when used or stored in poorly ventilated areas. Although nitrogen is nontoxic and inert, it can act as a simple asphyxiant by displacing the oxygen in air to levels below that required to support life. Apply non-stick dressing and seek medical attention.
