Hydrogen cyanide: What is it and why is it dangerous?
Hydrogen cyanide sounds like something out of a science fiction film, but it is a real, highly toxic chemical that you need to take seriously. The question often comes up, "How dangerous is hydrogen cyanide really?" The short answer: extremely dangerous, even in small quantities.
What exactly is hydrogen cyanide?
Hydrogen cyanide (also known as prussic acid) is a colourless liquid or gas that evaporates quickly. Used in industry, it is also one of the most dangerous toxins known. You may encounter it in situations where it is used as pesticides, or in the production of certain plastics.
- It smells like bitter almonds (but not everyone can smell it).
- It can be absorbed through the skin, breath or mouth.
- Even a small amount can be deadly if not treated in time.
How does hydrogen cyanide work?
If you are exposed to hydrogen cyanide, it blocks the cells in your body from absorbing oxygen. This means you are literally suffocating at the cellular level, even though there is plenty of oxygen in the air. It sounds frightening, and it is. But rest assured, as long as you don't come into direct contact with it, the chances of exposure are very low.
Why is hydrogen cyanide still used?
Although hydrogen cyanide extremely toxic, it is still used in industry because of its effectiveness in certain processes, such as:
- Production of plastics: Consider products such as acrylics.
- Pesticides: Used to control unwanted insects and animals.
- Mines: It is used in the extraction of gold and silver.
But don't worry, there are strict safety regulations that ensure you are not simply exposed to it in everyday life.
Frequently asked questions about hydrogen cyanide
1. How do I know if I have been exposed to hydrogen cyanide?
Symptoms include headache, dizziness, rapid breathing, unconsciousness and, in extreme cases, death. When in the slightest doubt, seek medical attention.
2. How can I protect myself from hydrogen cyanide?
Most people need not worry about exposure unless you work in the chemical industry. If that is the case, make sure you have protective clothing and follow safety protocols.
3. Can hydrogen cyanide be found in household products?
In very small quantities, it can occur in certain products, but usually under strictly controlled conditions. Think of specific pesticides or industrial equipment.
What should you do in case of contact with hydrogen cyanide?
If you suspect you have come into contact with hydrogen cyanide, there are a few steps you should take immediately:
- Leave the contaminated area immediately.
- Find fresh air.
- Call emergency services immediately.
- Avoid contact with others to prevent spread.
Hydrogen cyanide may sound like something out of a nightmare, but with the right precautions, you don't have to worry about it. Safety regulations in industries ensure that you will probably never come into direct contact with this dangerous substance.
Final word on hydrogen cyanide
Be it industrial applications or rare accidents, hydrogen cyanide is a substance you should not think lightly about. Stay aware and be careful, but don't panic.
