What happens if the gas is not turned off

As we all know, coal gas is the gas obtained by dry distillation of coal, etc. Its main components are hydrogen, methane, ethylene, carbon monoxide, and a small amount of nitrogen, carbon dioxide, etc.

. Colorless, tasteless, odorless, poisonous. Used as fuel or chemical raw material. However, in recent years, there have been many cases of gas poisoning, so we must pay attention to gas in our lives.

The use and shut-off of gas can avoid disasters caused by improper operations. Let us now understand what will happen if the gas is not turned off!

1. Overview

Coal gas is a gas containing combustible components that is processed from coal as raw material. According to the processing method, gas properties and uses, it can be divided into: water gas and semi-water gas

, air gas (or producer gas).

These gases have a low calorific value, so they are collectively called low calorific value gases; the gas obtained by coking in the coal dry distillation method is called coke oven gas and blast furnace gas. It is a medium calorific value gas.

Provided as civilian fuel in cities. Carbon monoxide and hydrogen in coal gas are important chemical raw materials.

2. Precautions

Gas poisoning

Gas poisoning in the home mainly refers to carbon monoxide poisoning, liquefied petroleum gas, pipeline gas, and natural gas poisoning. The former is more common in winter when coal stoves are used for heating with doors and windows closed.

The latter is common in leakage of liquefied gas stoves or gas pipelines. Coal gas easily combines with hemoglobin in the human body. When gas poisoning occurs, the patient initially feels headache, dizziness, nausea,

Heart palpitations, vomiting, weakness, when he realizes that he is poisoned, he often struggles to get out of bed to open the door and window, but generally only a few people can open the door, and most patients quickly convulse and become comatose

The skin on the cheeks, chest and lips are cherry red. If not treated in time, the patient may quickly suffer from respiratory depression and die. Gas poisoning depends on the concentration of carbon monoxide in the inhaled air.

When the volume of carbon monoxide in the room reaches 0.06%, people will feel dizzy, headache, nausea, vomiting, weakness in the limbs, etc.; when it exceeds 0.1%, just inhaling for half an hour will cause

When the concentration of alcohol reaches 0.4%, people will become drowsy and then fall into a coma; when it reaches 0.4%, it can cause death after just one hour of inhalation.
