Nitrogen Safety Training
METI’s Nitrogen Safety Training gives you and your workers everything you need to know about this frequently lethal, colorless, industrial chemical. Our course delivers training in nitrogen’s properties, common uses, health effects and recommended risk management & safe work practices. Nitrogen is a fascinating element with many unique properties and uses related to fertilizer, dynamite, medical anesthetic and even car racing. It can be used to replace air and eliminate oxidation of materials. Its most important use is in creating ammonia, which in turn is used to make fertilizer and explosives. Liquid nitrogen is used as a refrigerant for very low temperatures. Nitrogen’s potential to harm workers in or near confined spaces should never be underestimated. Learn to safely work with nitrogen in the workplace.

Why is nitrogen gas so dangerous?
Nitrogen is a colorless, odorless and tasteless gas. Any rapid release of nitrogen gas into an enclosed space can displace oxygen, and therefore represents an asphyxiation (suffocation) hazard.
When LN2 boils it produces gaseous nitrogen, which displaces oxygen from the air. This results in an oxygen-deficient atmosphere, particularly if vented into a closed space, and asphyxia can result.
Due to its extremely low temperature, the cold vapour and gas that are produced when LN2 boils can give rise to cold burns or frostbite upon contact with unprotected skin. Exposure may also produce discomfort in breathing and can provoke an asthma attack in susceptible individuals.
Fire in Oxygen-Enriched Atmospheres
LN2 can condense oxygen from the atmosphere. Liquid oxygen creates potentially flammable or explosive conditions by greatly increasing the combustibility of many materials (e.g. solvents, hydrocarbons).
Pressure Build-up/Ice Plug Formation
Due to the large expansion ratio (liquid to gas), if LN2 is evaporating within a closed system, the pressure can build up with a high risk of explosion. Ice plugs can form on the neck of narrow storage vessels if there is no relief vent, as water is readily condensed by LN2 to form ice. This will lead to pressure build up in the storage vessel.
What happens if you become in direct contact?
Direct skin contact with liquid nitrogen will eventually cause severe frostbite . This may happen almost instantly on contact, or after a second or more, depending on the form of liquid nitrogen.
What can happen if nitrogen is inhaled?
When inhaled, nitrogen begins to act as an anesthetic agent. It can cause nitrogen narcosis, a temporary semi-anesthetized state of mental impairment.
What training will this Nitrogen Safety Training Course provide?
It is important that employees know how to properly receive, transport, use, store, and safely handle compressed nitrogen gas cylinders.
Your Nitrogen Safety Ticket/Certificate
Upon completion of this training, you will receive a wallet-size Ticket/Certificate, that will show prospective employers that you have the credentials. Employers may require confirmation of your Certificate. We keep your records on file permanently. Feel free to have your prospective employer contact METI to confirm your Certification.
