Fume Hoods
Fume Hoods: Critical Safety Devices
Fume hoods are critical safety devices used in laboratories and industrial environments to protect users from harmful fumes, vapors, gases, and airborne contaminants. These devices are designed to contain and exhaust hazardous substances away from the user and the environment.
A typical fume hood consists of a vented enclosure, usually equipped with an adjustable sash (a glass panel) and an airflow system that captures and directs the contaminated air to the outside or through a filtration system. Fume hoods are commonly used in laboratories, chemical plants, and areas where dangerous chemicals, toxic gases, or volatile substances are handled.
There are various types of fume hoods, and understanding the terminology related to fume hoods is crucial to making an informed decision while purchasing fume hoods.
