Helium gas is always present around us and is a component of all types of natural gas. Helium is used in various fields such as medicine and daily life. And most commonly, it is used to inflate balloons. Surely many people have inhaled helium gas from balloons at least once. So, what is helium gas, is helium gas toxic, is it flammable or explosive? Is inhaling helium gas dangerous?

What is helium?

Helium gas (He) is fully called helium gas. It is a gas found in large quantities in the universe.

What is pure helium gas

Helium is an element in the periodic table of elements with the symbol He. The name of this element comes from Helios, the name of the Sun god in Greek mythology, because the origin of this element was found in the spectrum of the Sun.

Chemical symbol: He
Atomic mass: 4.002602 u
Melting point: -272.2 °C
Boiling point: -268.93 °C
Atomic number: 2

What are the properties of helium gas?

Helium is a colorless, odorless, non-toxic, tasteless gas that is lighter than air. It is an inert gas that does not react with any other substances.

Helium is not a renewable resource

Because helium is an inert gas, it does not react with any other gases. Therefore, this resource cannot be regenerated. This resource will gradually decrease over time.

Is helium gas toxic? Is it flammable or explosive?

Before answering the question “Is helium gas toxic?”, let’s review the applications of this inert gas:

Applications in the medical field
It is a component in the breathing mixture of divers.
Applications in analysis and experimentation
Applications in daily life and entertainment
Laser, gas chromatography,…

Going back to the initial question, let’s analyze: Because helium is used in medicine and in breathing mixtures, it cannot be toxic. Therefore, it can be said that helium is not toxic and does not harm health.

However, in entertainment applications: inflating balloons, airships, changing voice, etc., if not used properly, it can affect our health.

Is inhaling helium gas to change your voice dangerous?

Balloons are a popular form of entertainment for children. In addition, balloons are an indispensable decoration at various events, big or small.

Simple self-inflation of balloons at home

Recently, young people have been increasingly experimenting with inhaling helium gas from helium balloons to create funny voice changes.

Many parents worry about this and ask if inhaling helium gas is harmful.

According to Master of Chemistry Vo Tan Ngoc:

Helium-filled balloons initially float very quickly. But after about 4-5 hours, the balloons gradually become heavier and descend to the ground.
This is because helium, over time, permeates through the rubber membrane and escapes into the air. If there are many helium balloons in a closed room, it can cause oxygen deficiency, leading to asphyxiation and difficulty breathing. Prolonged exposure to this situation can be fatal.
Therefore, balloons should not be kept in closed rooms.
In addition, balloons are made from materials that are not good for health. So, children should not suck or blow up balloons.

So, is inhaling helium gas toxic?

If parents are concerned about this, the answer is that inhaling helium is not toxic. We can inhale helium gas objectively or subjectively.

Helium is an inert gas, containing no harmful components. Therefore, if your child accidentally inhales this gas, there is no need to worry!

However, during use, some precautions should be taken to ensure safety.

Precautions when using helium gas cylinders to inflate balloons

Instructions on how to inflate balloons with helium gas at home

Here are some safety guidelines to follow when using helium gas cylinders to inflate balloons:

Place the cylinder upright and securely in a safe location, away from high-traffic areas.
Do not inflate balloons in a closed room to avoid asphyxiation.
Do not release gas directly from high-pressure cylinders.
Use a pressure regulator during use.
Close the cylinder valve tightly, remove the pressure regulator, and replace the valve cap after each use.
Do not attempt to refill the cylinders yourself.
Keep away from heat sources and out of reach of children.

What happens when you inhale helium gas into your lungs?

With a basic understanding of helium gas, you can be completely assured of its safety. However, there is something that happens when you inhale helium gas that might surprise you.

Gas that distorts the voice

The nickname “voice-distorting gas” or “voice-changing helium gas” is given by young people. Because when you inhale helium gas into your lungs, your voice will immediately change, sounding like a cartoon character.

The mechanism behind this phenomenon is simple:

Helium is much lighter than air, so the speed of sound in helium is about 3 times faster than in air. Therefore, the frequency of sound waves traveling through helium is much higher than when traveling through air.
When you inhale helium gas, your throat is filled with this gas. As a result, the voice frequency changes, increasing significantly, and making your voice higher and clearer. However, because the amount of helium gas in the balloon is low, the “cartoon voice” effect only lasts for a short time before returning to normal.

This interesting phenomenon has been tried by many people. For entertainment or professional purposes, this gas is a safe way to change your voice for a short period after inhalation.

You or your loved ones can try this fun experiment with helium gas at home. But remember to use helium gas in moderation and within safe limits. Excessive use can lead to lung strain.

Is helium gas flammable or explosive?

As defined above, helium gas is a noble gas, an inert gas. It does not react with any other substances. Therefore, helium is not flammable or explosive.

However, there is a big question about balloon explosions and whether helium gas is involved.

This is a common misconception about this gas. For profit and to reduce the price of balloons, people often use hydrogen gas instead of helium. Hydrogen gas is highly flammable and explosive. It is very dangerous, especially for children. Therefore, you need to be cautious when using hydrogen-filled balloons.

Is helium gas dangerous?

As an inert gas that does not react with any other substances, helium is not inherently dangerous.

So, are there any internal factors that make helium gas dangerous?

Helium cannot solidify and can only liquefy at absolute zero temperature under standard pressure, an environment found only in research laboratories.

Therefore, it can be concluded that helium gas is not dangerous.

Is helium gas dangerous? The clear answer is no. However, users need to be careful when using this inert gas.
Especially those who use helium gas for entertainment purposes, specifically to temporarily change their voice.

What are some risks of using helium gas?

Excessive use of helium gas to change voice may have health effects. Although there is no scientific research or report to support this claim.

However, young people who use helium gas to change their voice excessively have reported that “it makes us feel excited.”

There is no scientific evidence to support this claim. It may be a side effect of inhaling too much gas, causing oxygen deprivation in the brain, leading to a lightheaded feeling.

In addition, you must never inhale gas directly from compressed gas cylinders. The pressure inside the cylinders is extremely high. When released suddenly, the gas will escape at high speed, potentially rupturing lung tissue and causing gas embolism, leading to stroke and even death. Therefore, you should be cautious with this experiment!
