How to Prevent Hazardous Gases in Chemical Laboratories
At 15:30 on March 11, 2025, a combustion and explosion accident occurred in an industrial park of a biotech company in Taizhou, Jiangsu Province. The accident killed 4 people and injured 4 others. After the explosion, thick smoke billowed from the scene, and the smoke was purple, suspected to be caused by the explosion of chemical products.
Gas Safety Hazards in Chemical Laboratories
In the chemical industry, due to the special nature of chemicals, combustion and explosion accidents are prone to occur. Many universities, research institutions, or industrial enterprises have chemical laboratories, which also involve a variety of chemicals.
During the processes of laboratory research, experimental operations, and chemical storage, there are numerous types of reagents, liquids, and gases in use. Many of the gases volatilized from them are flammable, explosive, toxic, and harmful, such as methane, hydrogen, hydrogen sulfide, etc. These gases may be generated during the experiment or leak from gas cylinders, leading to accidents such as combustion, explosion, and poisoning, threatening the safety of laboratory personnel.
In recent years, laboratory accidents have occurred frequently in various places, and the safety situation cannot be ignored. The personnel in laboratories have high mobility and the equipment is used frequently, making it extremely easy to have safety accidents. Therefore, gas detection in various laboratory scenarios has become an industry consensus. Through real-time monitoring and early warning, accidents such as gas leakage, explosion, and poisoning can be effectively prevented, ensuring the safety and health of the laboratory environment.
What are the Common Hazardous Gases in Laboratories?
Common hazardous gases in laboratories include nitrogen dioxide, carbon monoxide, methane, sulfur dioxide, chlorine, ammonia, fluorine, hydrogen sulfide, phosgene, ozone, hydrogen chloride, arsine, phosphine, etc. The most important toxic gases in laboratory testing rooms are sulfur dioxide, carbon monoxide, nitrogen dioxide, chlorine, and hydrogen sulfide.
Whether it is a poisoning accident or an explosion accident, the consequences will be extremely serious once they occur. Therefore, Gas Detectors must be installed in key areas of laboratories where high - risk flammable liquids or toxic solutions are present! Detect the gas content in a timely manner, issue alarm signals as early as possible, or activate the interlock protection system to minimize the accident losses.
Chemical Laboratory Toxic and Hazardous Gas Online Detection System Solution
The CAATM Chemical Laboratory Toxic and Hazardous Gas Online Detection System Solution consists of gas detectors distributed in key monitoring areas to detect the gas concentration in the surrounding environment at any time. Laboratory personnel can conduct multi-location detections of multiple hazardous gases by wearing Portable Gas Detectors, which can promptly remind them. Supervisors can monitor through mobile phones or computer terminals. Once it is detected that the concentration of harmful gases exceeds the standard, corresponding measures such as ventilation will be taken immediately to ensure the safety and health of the environment.
Product Recommendations
Replacing manual work with automation to achieve real-time monitoring of gas concentration can help discover problems in a timely manner, respond quickly, improve work efficiency, and ensure the safety of personnel to the greatest extent.
