LOGO LOGO Name：Ke Zunying SN:0000326D Chemical Logistics Hazardous chemical symbols around us This symbol means the substance is toxic Page ? * I find the symbol clinging on the bottle filled with trichloromethane that stored in the lab.  CHCL3 in light air oxidation generates highly toxic phosgene was gradually, so you need to save in a sealed Brown jar. Chloroform is a highly toxic chemical substances. Acute poisoning caused by inhaled or absorbed through the skin. Initial are headache, dizziness, nausea, vomiting, damp heat, tingling, skin and mucous membrane irritation. Later psychiatric disorders, breathing shallow, and other influences. So the bottle should be posted this symbol. Hazardous chemical symbols around us Inflammable materials This symbol I find it posted on the gas tank in my kitchen. The main ingredient in household natural gas is methane, also contain small amounts of ethane, butane, pentane, hydrogen sulfide, carbon dioxide, carbon monoxide, etc, in a common sense, these gases are flammable, so the tank is posted the inflammable symbol. And this flammable gases in a sealed bottle are usually explosive, so it should also be posted a explosive symbol. Cooking gas containing carbon monoxide, it is a colorless, odorless, and tasteless gas, if inhaled, will cause very big damage to the human body. Carbon monoxide poisoning causes headache, nausea, vomiting, dizziness, feeling of fatigue and weakness. There are many hazardous substances around us, such as the Petron save, is may be ignited by a neglected cigarette butts, and lead a disaster. And the chemical lab, there are many kinds of hazardous chemical material that may cause hurt to you. And others . Page ? * What I learn in this stud We will meet more hazardous materials in work, and may need to translate them. But we don’t need to afraid them , we can be safely handle them by understanding some basic chemical principles and employing clear and concise thinking. We should always alert
