Hazardous Material Identification

UN Number: 1963

Chemical Name: Helium, Refrigerated Liquid

Hazard Class: 2.2 (Non-Flammable Gas)

Placard Appearance: Green background with a white gas cylinder symbol and the number 2.2 below.

First Aid Steps:

Inhalation: Move the victim to fresh air immediately. If breathing is difficult, administer oxygen and seek medical attention.

Skin Contact (Frostbite Risk): If contact with liquid helium occurs, do not rub the affected area. Immerse in lukewarm water (not hot) and seek medical help.

Eye Contact: If exposed to the cold gas or liquid, flush eyes with lukewarm water and seek immediate medical attention.

Ingestion: Not applicable—helium is a gas at standard conditions.

Hazard Class Explanation:

Helium is a non-flammable, cryogenic gas that can cause frostbite upon contact with skin.

In enclosed spaces, it can displace oxygen, leading to asphyxiation without warning.

Although it does not burn, rapid expansion or pressure buildup in containers can cause explosions if not properly vented.

Real-World Application for Emergency Response:

Ventilation: In confined spaces, responders must ensure proper ventilation to prevent asphyxiation.

Cryogenic Burns: Protective gloves and face shields are necessary when handling liquid helium to prevent frostbite injuries.

Container Handling: Pressurized tanks must be secured and stored upright to prevent accidental release.

Evacuation: Generally, no large-scale evacuation is needed unless in an oxygen-deficient environment or if a tank ruptures.
