Alternatively known as exhaust hoods, laboratory fume hoods are vital in laboratory operations. Hazardous chemical work is a common occurrence in many labs, and the right exhaust hood can provide an enclosed space for lab personnel to carry out such activities. Although some people make the mistake of using a laboratory fume hood as a storage cabinet, this practice should be discouraged through proper training.
Why Exhaust Hoods are Important
The importance of this equipment is highlighted by the hazards from which it protects lab personnel, including;
1. Chemical/thermal burns
2. Chemical absorption
3. Inhalation of harmful vapors
4. Fires/explosions
Part of a Whole
Designed to function as a workstation, laboratory fume hoods form part of a comprehensive system also comprising a base cabinet, work surface, duct work, and exhaust blower.
Factors for Purchase
1. Size: All the work done in a fume hood must be at least six inches behind the sash. In addition, there must be space provided underneath any equipment in the fume hood. These lead to the following compelling questions;
a. How much space is available in the laboratory?
b. Is the fume hood to be mounted on an existing countertop?
c. What’s its depth?
2. Function: It is important to know the kind of chemicals that will be used within the fume hood. Additionally, the extent of protection must be known, as some circumstances require personnel protection while others require both personnel and product protection.
3. Air Supply: Depending on the chemicals and instruments in use within the fume hood, a choice will need to be made between a constant air movement hood and a variable air movement hood.
Laboratory fume hoods are indispensable in the operations of a laboratory, primarily for the protection of personnel. It is noteworthy that fume hoods also offer protection for the products.
