Biogas hazard characteristics, what are the hazards of biogas?

Biogas is a slightly toxic type. Allows the gas to safely diffuse into the atmosphere or be used as a fuel. It has a simple asphyxia effect, and poisoning is caused by hypoxic asphyxia at high concentrations. In the air up to 25-30% appear dizziness, rapid breathing, dyskinesia.

anesthetic effect; Rabbit inhaled 42% concentration for 60 minutes, anesthetic effect.

Hazard characteristics: flammable, mixed with air to form a first-class mixture, there is a risk of burning when exposed to heat sources and open flames. It reacts violently with bromine pentoxide, chlorine, hypochlorous acid, nitrogen trifluoride, liquid oxygen, oxygen difluoride and other strong oxidants.

Combustion (decomposition) products: carbon monoxide, carbon dioxide.

Biogas is the gas found in swampy wetlands.

Biogas is a kind of combustible gas produced by microbial fermentation of organic substances in an anaerobic environment under certain temperature, humidity and pH conditions. Since this gas is first found in swamps, lakes, ponds, people call it biogas. Biogas contains a variety of gases, the main component of which is methane (CH4).

Biogas fermentation is called biogas fermentation when biogas bacteria decompose organic matter and produce biogas. According to the role of various types of bacteria in the biogas fermentation process, biogas bacteria can be divided into two categories. The first type of bacteria is called decomposers, which are used to break down complex organic matter into simple organic matter and carbon dioxide (CO2).

Among them, there are those who specialize in breaking down cellulose, called fibrolytic bacteria; There are those that specialize in decomposing proteins, which are called proteolytic bacteria; There are those that specialize in decomposing fat, called lipolytic bacteria; The second type of bacteria is called methane-containing bacteria, commonly called methanognes, which oxidizes or reduces simple organic matter and carbon dioxide to methane.

Therefore, the process of turning organic matter into biogas is like the two processes of producing a product in a factory: first, decompose bacteria and process complex organic matter such as manure, straw, and weeds into semi-finished products - compounds with simple structures; Then there's the methane bacteria that process simple compounds into products – methane.

Health Hazard Invasion Route: Inhalation.

Health hazards: Methane is basically non-toxic to humans, but when the concentration is too high, the content of oxygen in the air is significantly reduced, making people suffocate. When the methane in the air reaches 25%-30%, it can cause headache, dizziness, fatigue, difficulty concentrating, rapid breathing and heartbeat, and ataxia.

If you don't stay away in time, you can die of suffocation. **Exposure to liquefied methane can cause frostbite.

Toxicological data and environmental behavior: Toxicity: Slightly toxic.

Allows the gas to safely diffuse into the atmosphere or be used as a fuel. It has a simple asphyxia effect, and poisoning is caused by hypoxic asphyxia at high concentrations. In the air up to 25-30% appear dizziness, rapid breathing, dyskinesia.

Acute toxicity: mice inhaled at 42% concentration for 60 minutes, anesthetic effect; Rabbit inhaled 42% concentration for 60 minutes, anesthetic effect. Hazard characteristics:

It is flammable, mixed with air to form a first-class mixture, and there is a danger of burning when exposed to heat sources and open flames. It reacts violently with bromine pentoxide, chlorine, hypochlorous acid, nitrogen trifluoride, liquid oxygen, oxygen difluoride and other strong oxidants. Combustion (decomposition) products:

Carbon monoxide, carbon dioxide, and water.
