Here are the ten most dangerous chemicals in the world ever known to mankind.

Fact: there are chemicals all around us. Of course! We eat, drink, breathe them all the time, and how lucky you’re still alive to read this article. Most people think of the word chemical as any harmful, toxic, or dangerous substance that’s a threat to us. Truth is, some chemicals are way subtle than you think.

However, with your preconception in mind, there are dangerous chemicals, too. They’re poisonous, corrosive, volatile — that could set concrete on fire — with others having a pungent smell that induce vomiting, others can even cause cancer. Yes, your thoughts were right. Dear friends, here are the top ten most dangerous chemicals ever known to mankind. They pose a threat if you ever come into contact with them, so here’s what to do if you’re accidentally exposed to these substances. You’re WARNED!


If for any reason you ingest or come into contact with a potentially harmful chemical substance, call 911 (or the emergency services number for your country or state) immediately, and request help from medical authorities. For additional help, contact the 24-hour American Association of Poison Control Centers (ASPCA) at 1-800-222-1222; but if an animal or your pet has been exposed, contact the ASPCA National Animal Poison Control Center at 1-888-426-4435.
