Toxic and harmful gases such as hydrogen sulfide, biogas, and liquefied petroleum gas may cause accidents such as poisoning and explosion, endangering the lives and property of nearby residents. Toxic gas leakage seriously endangers people’s lives and safety, and needs to be focused on prevention.
Toxic and harmful gases can cause serious harm to human health and the environment. These gases come from various sources, including industrial production, transportation, domestic combustion, agricultural fertilization, and volcanic eruptions in nature. Different toxic and harmful gases have different toxic mechanisms and degrees of harm, and corresponding prevention and control measures need to be taken.
What are the common toxic and harmful gases?
Common toxic and harmful gases can be divided into the following categories according to their toxic properties:
① Irritant gases – refers to gases that are irritating to the eyes and respiratory mucosa.
② Asphyxiating gases – refers to toxic gases that can cause hypoxia in the body.
>>> Irritant gases: Irritant gases are toxic gases commonly encountered in the chemical industry. There are many types of irritating gases, the most common ones are chlorine, ammonia, nitrogen oxides, phosgene, hydrogen fluoride, sulfur dioxide, sulfur trioxide and dimethyl sulfate.
>>> Asphyxiating gases: Asphyxiating gases refer to harmful gases that, after being inhaled by the body, hinder the supply, intake, transportation and utilization of oxygen, so that the tissue cells of the whole body cannot get or cannot use oxygen, resulting in hypoxia and suffocation of the body. It can be divided into simple asphyxiating gases and chemical asphyxiating gases. Such as nitrogen, methane, ethane, ethylene, carbon monoxide, nitrobenzene vapor, hydrogen cyanide, hydrogen sulfide, etc.
In addition to the above two types of gases, there are many other common toxic and harmful gases that deserve our attention. For example↓↓↓
Sulfur dioxide (SO₂) mainly comes from the combustion process of coal and oil, which has a strong irritating effect on the respiratory tract and eyes;
Nitrogen dioxide (NO₂) is common in fuel combustion and chemical industrial production processes, which can cause acute asthma and emphysema;
Phosgene is a highly toxic gas, mainly present in environments such as phosgene production and high-temperature combustion of chlorocarbons, which can cause severe pulmonary edema and suffocation;
Hydrogen sulfide (H₂S) has the smell of rotten eggs, but at high concentrations it can paralyze the sense of smell, leading to suffocation and death.
Once these gases leak, they are very harmful, so we must always be vigilant and take effective measures to prevent the possible harm they may bring.
Gas safety solution: The solution consists of an environmental equipment monitoring system, a data transmission system, and a data monitoring system. By placing various sensors such as combustible and toxic and harmful gas detection alarms in the chemical park, the gas concentration and environmental parameters of each link in the chemical park are monitored in real time.
The gas detector converts the leakage concentration of toxic and harmful gases in the environment into a digital signal and sends it to the controller, which displays the concentration of the measured gas after receiving it. When the preset value is reached, the controller will send out an audible and visual alarm signal and transmit the signal to the computer terminal. If there are linkage devices such as exhaust and shut-off valves installed, the exhaust, shut-off, and spray systems can also be started to prevent explosions, fires, and poisoning accidents, thereby ensuring safe production.
In addition, for safety inspections or limited space operations, you can also choose to use a portable gas detector. According to actual needs, you can wear a single gas detector or a composite gas detector to prevent accidents by real-time monitoring of the concentration of toxic and harmful gas leakage in the working environment.
