How To Use Laboratory Fume Hoods Reasonably?

Laboratory fume hood is a more common type of partial exhaust system equipment in laboratories, especially in physical and chemical laboratories, and is an essential experimental instrument for laboratory technicians. The quality of laboratory fume hoods immediately endangers the safety of workers. Even with high-quality laboratory fume hoods, if not operated properly, various problems can arise, which can harm the safety of testing personnel.
A laboratory fume hood is an enclosed indoor space that can also function as an exhaust system. The purpose of its design scheme is to better manipulate, dilute, and remove the smoke, mist, and particles that cause production and manufacturing in this enclosed space. In addition, it is also a key component of preventing leakage manipulation in the laboratory.
In most laboratories, the laboratory fume hood is a key control system for maintaining laboratory workers from being damaged by harmful compounds. In addition, laboratory fume hoods can also have maintenance effects on sudden fire accidents, explosions, and compound spills at the minimum practical operating height. A typical laboratory fume hood consists of a kitchen cabinet paired with a themed sliding door made of tempered glass or laminated glass.
The principle of all laboratory fume hoods is based on the reasonable control of harmful substances. The relative negative pressure in the natural environment effectively blocks the external diffusion of harmful chemicals, and the fresh air in the room enters its enclosed inner wall at a stable rate through the sliding door of the laboratory fume hood.
The entire experimental process is carried out continuously in the laboratory fume hood. Generally, the laboratory fume hood is connected to the exhaust system piping system software and smoke exhaust fan to ensure continuous safety of the exhaust system. When harmful substances are removed into the external ambient air, compounds still have harmful effects on people's physical and mental health even after being diluted by air. When air pollution is given sufficient attention, organic waste gas treatment system software may be installed to address harmful substances in organic waste gas.
The appropriate wind speed level is particularly important for safe and efficient laboratory fume hoods in practical operation. Excessive surface wind speed levels may cause flow fields and reduce their control over harmful substances, while excessively low surface wind speed levels can also harm the characteristics of laboratory fume hoods.
