Several guidelines and regulations are established to maintain safety measures for operating fume hoods. In this article, we will discuss the standard for fume hoods.

The main standards used for designing, manufacturing, and testing fume hoods are:

1. ASHRAE 110: It defines the testing process for fume hoods to measure the uniformity of the airflow and the maximum concentration of contaminants.
2. SEFA 1: It is a design guide for laboratory fume hoods, which specifies the recommended dimensions, sash opening height and velocity, materials, and other relevant details.
3. NFPA 45: It is a standard on fire protection measures for laboratory hoods.

It is essential to adhere to these standards to ensure the safety of the laboratory environment.
