Be careful with fans in the lab

Lab Safety Advisor, May 1, 2007

Fans have been used for years to improve the air circulation in labs. As instrumentation has gotten bigger, and the heat output greater, the use of fans has become more prevalent.

This is a temporary fix, however, one that addresses the symptom but does not solve the basic problem. You don't have enough cool air circulation coming into the lab.

Fans stir up the particles in the air and on the bench tops and floors. It is an infection control issue, and fans cannot be used where microbiology plating or reading is done for fear of contamination.

Don't use fans as a stopgap measure. Get at the root of the problem and solve it. It will save you money in the long run.
