What are the hazards of helium?

3 min read

Asked by: Cheryl Caldwell

Helium is non-toxic and inert. Inhalation in excessive concentrations can result in dizziness, nausea, vomiting, loss of consciousness, and death.

Is helium toxic or flammable?


Helium is non-toxic and non-flammable.

What happens when you inhale helium from a balloon?

If you inhale helium from a balloon, you get a squeaky voice. You might also get light-headed because you’re breathing in pure helium gas rather than oxygen-containing air. This can lead to hypoxia or low oxygen.

Can helium burn your skin?

Helium is an inert gas that is not harmful to the environment or to humans. However, asphyxiation can result from its use in an oxygen-poor environment, and liquid helium is cold enough to “burn” human skin.

Is compressed helium hazardous?

Inhalation : No known significant effects or critical hazards. Skin contact : Contact with rapidly expanding gas may cause burns or frostbite.

Is it safe to suck in helium from a balloon?

Helium is perfectly safe in balloons and safe when balloons are deflated in open and well-ventilated areas but, inhaling it from balloons can be dangerous. Helium displaces oxygen in your lungs when you inhale it, which can cause suffocation and you won’t even realize it.

What causes helium to explode?

As it is an inert gas, helium will not react with any other substances and remains very stable. This means that a helium balloon cannot explode – if it comes into contact with a flame or heat source, the balloon will just pop like any other ordinary inflated balloon.

What helium does to your voice?

Inhaling helium makes the higher-pitched tones resonate more in the vocal tract, amplifying them so they are louder in the mix. At the same time, it makes the lower tones resonate less in the vocal tract. The two effects combine to create a Chipmunk-like, flat sound.

Is helium laughing gas?

As is the case with many other inhalants such as nitrous oxide (also known as laughing gas), computer cleaner, and nitrites, helium is used recreationally by young people, primarily teenagers, and is often referred to as whippets, air blast, snappers, or hippie crack.

What gas makes your voice deeper?

Sulfur Hexafluoride (SF6)

The Deep Voice Gas – Sulfur Hexafluoride (SF6) – Steve Spangler Science.

Is liquid Helium flammable?

Perhaps the most familiar use of helium is as a safe, non-flammable gas to fill party and parade balloons. However, helium is a critical component in many fields, including scientific research, medical technology, high-tech manufacturing, space exploration, and national defense.

Can a helium tank explode?

Helium tanks cannot explode. The reason is because the cylinders are equipped with an approved burst disc. It is located on the top of the tank next to the handles. In case of any unforeseen circumstances, such as a fire, the cylinder will release gas in a controlled manner and will not explode.

Does helium react with water?

Atomic helium does not react with water, nor with any other substance. (We can now produce some non-stable helium compounds, such as VHe3+ and HePtHe2+). No single gas has a lower solubility than does helium.

Why does NASA use so much helium?

NASA uses helium as an inert purge gas for hydrogen systems and a pressurizing agent for ground and flight fluid systems. Helium is also used throughout the agency as a cryogenic agent for cooling various materials and has been used in precision welding applications.

Is helium an explosive?

The answer is simply, no. Helium is an inert gas. Inert quite literally means non-combustible. In fact, helium (in its liquid state) is actually used as a coolant for things like rocket ships, MRI machines, and particle accelerators.

Will the world run out of helium?

Once the gas leaks into the atmosphere, it is light enough to escape the Earth’s gravitational field so it bleeds off into space, never to return. We may run out of helium within 25–30 years because it’s being consumed so freely.
