Nitrogen cylinders offer a reliable way to store and transport nitrogen gas, but they can be dangerous if handled or stored improperly. Always follow safety precautions when using nitrogen cylinders.


Nitrogen is a colourless, odourless gas used in plasma cutting, laser cutting, tire inflation, shrink-wrapping and heat-treatment processes. Nitrogen is non-toxic and non-flammable, but it displaces oxygen, which can cause asphyxiation. In addition, highly pressurised cylinders pose dangers.

Storage and Transport

Store nitrogen cylinders upright in a dry, well-ventilated area. Secure nitrogen cylinders with a chain and separate empty from full cylinders. Clearly label all gas cylinders. Do not drag or roll nitrogen cylinders. Instead, secure cylinders to a cart in order to transport them.

Safe Use

Use nitrogen cylinders in a well-ventilated area to prevent asphyxiation. Avoid inhaling nitrogen gas. Keep flames and open electrical circuits away from nitrogen cylinders and do not heat nitrogen cylinders.

First Aid

If an employee inhales nitrogen or suffers asphyxiation from oxygen removal, move the person to fresh air and give CPR or oxygen if necessary. Seek medical attention if necessary.
