MINIMIZE TRAFFIC NEAR THE OPENING
When a hood is installed, make sure it isn’t in a location where personnel have to pass in front of it.
Avoid making fast movements when taking items in and out of the hood. This will disrupt the airflow, allowing contaminants to leave the hood.
When working inside the hood, users should ensure that chemicals are kept at least six inches back from the face. If they're placed closer, vapors won’t be captured efficiently.
