Nitrous oxide, aka laughing gas, is a colorless, non-flammable gas commonly used in medical, food and beverage, automotive, and other industries. While it is relatively safe when handled properly, it can be dangerous if not stored, transported, and handled with care. Here are some safety considerations to keep in mind when handling nitrous oxide.

Proper Storage

Nitrous oxide should be stored in a cool, dry, and well-ventilated area. It should be stored in a securely sealed container designed to hold the gas and not be stored near any ignition sources. Nitrous tanks should also be kept from flammable materials such as gasoline, oils, or other fuels.


Nitrous oxide can displace oxygen, leading to asphyxiation. Proper ventilation is essential to prevent the build-up of nitrous oxide in confined spaces. Nitrous oxide should only be used in well-ventilated areas and should never be used in a confined space without proper ventilation. The ventilation system should be designed to move air away from work areas.

Personal Protective Equipment

When handling nitrous oxide, wearing personal protective equipment, such as gloves, safety goggles, and a respiratory mask is essential. Gloves should be made of a material resistant to nitrous oxide and checked regularly for damage. Safety goggles are necessary to protect the eyes from exposure to nitrous oxide, and one should wear a respiratory mask to avoid inhaling the gas.


Nitrous oxide must be transported in a properly secured container designed to hold the gas. The container must be appropriately labeled and secured to prevent tipping or spilling. During transportation, it is essential to ensure that the container is not exposed to heat or direct sunlight. Nitrous tanks should always be transported in a secure and upright position. Tanks should never be transported in the trunk of a car or the back of a truck, as this can expose them to heat and direct sunlight.

Handling Procedures

Nitrous oxide should only be handled by trained personnel familiar with proper procedures. Before using nitrous oxide, it is essential to read and follow the manufacturer’s instructions. One should open the valve on the container slowly to prevent sudden pressure changes and keep the container away from heat sources during use.

Additionally, when not in use, the valve should be kept closed to prevent the accidental release of gas. Always use the tank’s pressure gauge to check the pressure before use. Never exceed the maximum pressure limit of the tank.

Emergency Procedures

In case of an emergency, it is essential to have the plan to handle the situation. All employees should be familiar with the emergency procedures for nitrous oxide, which should include proper ventilation, evacuation, and contacting emergency services.


Nitrous oxide is a valuable gas with many applications, but it can be dangerous if not handled properly. Proper storage, ventilation, personal protective equipment, transportation, handling procedures, and emergency procedures are all essential to ensure the safe handling of nitrous oxide. Handlers can minimize the risk of injury or damage by following these safety considerations.
