Safely Handle a Liquid Nitrogen Dewar

Safety experts say that nitrogen, despite its inert quality, causes more fatalities than any other chemical found in laboratories. That's why it's important that your cryogenic freezer system has a high-quality, reliable liquid nitrogen dewar. Our staff at Princeton Cryo Tech will always make sure that every one of our products, including dewars, are the highest quality. It's the best way we can help avoid catastrophic events occurring in a laboratory.

When a person is surrounded in a purely nitrogen atmosphere, oxygen flow is reversed from the arterial blood and tissues back into the lungs, causing unconsciousness. This is a very dangerous situation and similar effects can occur when working with liquid nitrogen in a laboratory setting. Liquid nitrogen chilled vapor collects near the floor, but can still cause unconsciousness after inhaling the vapor. Interestingly, though, over half of workers who die in confined spaces are attempting to rescue unconscious workers. So not only are the unconscious in danger, so are the people who try to help them.

If you work with nitrogen in your lab, it's important to have up-to-date safety meetings. In addition to meetings, training should take place, along with maintaining the best quality liquid nitrogen containers and equipment. Princeton Cryo makes sure that all of our products, like a liquid nitrogen dewar, will prevent laboratory accidents.

Dewars are designed for storing and dispensing liquid nitrogen. They are easy to operate and are constructed of high-quality materials. For more safety insurance, laboratories should be equipped with high-quality cryo gloves while keeping employees informed of all the proper safety techniques when handling these dangerous chemicals. Most of all make sure you have a reliable liquid nitrogen dewar from Princeton Cryo.
