      .Minimize release of contaminants into the work ara by reducing pedestrian traffic in front of hoods, particularly during hazardous experiments. Also minimize nearby disturbances, such as doors opening or closing, people walking by, and any quick motion in order to prevent cross drafts.
Do not block airfoil: Many labs place absorbent paper on the floor of the hood and over the airfoil to catch spills. The airfoil provides airflow across the floor of the hood, especially when the sash is closed. If you use absorbent paper in the hood, please do not block the airfoil.
Place bulky equipment away from sidewalls to allow airflow around the equipment.
Place any bulky equipment towards the rear of the hood and raise it about 2 inches off the surface with blocks or bricks. This will allow airflow around and under the equipment. Equipment placed near the hood face will cause great variation in airflow. This equipment must be moved towards the rear of the hood, but do not place this equipment against the rear wall of the hood, as it will block airflow to the rear baffles.
Work as far inside the hood as possible, at least 4 to 6 inches from the front edge with the sash face between you and task at hand. All equipment should be a minimum of 9-12 inches away from the hood face.
Keep sash face clean and clear. To encourage use of sash as added protection against splashes, sprays, etc. keep sash face clean. If sash face must be blocked with paper for certain experiments, please take it down after the experiment is complete.
Do not use the hood as a storage cabinet for chemicals or equipment. Materials stored in fume hoods should be kept to a minimum and stored in a manner that will not interfere with airflow. This can be accomplished by equipping the hood with perforated shelves on the side walls and/or allowing at least 3 inch spaces between containers or equipment so air can flow around them to the back exhaust slot.
Place any heat-generating equipment in the rear of the hood. Heating devices in the hood produce convection currents that can disrupt airflow.
Do not use a hood for any function it was not designed for, such as acid, radioisotopes, etc. The generation of acid vapors requires specially designed fume hoods with wash-down systems. Failure to use a wash-down system will result in the deposit of explosive perchloric acid crystals that may detonate in the hood ductwork.
Close sash when finished with hood work or when leaving experiments or chemicals unattended! This simple procedure has contained many fires and explosions within a hood.
