Fume Hood Safety Tips
- Verify the exhaust system is operating before each use.
- Close the sash as much as possible when working at the fume hood – use the sash as a face shield.
- Close the sash completely when not working at the fume hood.
- Avoid placing your head inside the fume hood.
- Avoid rapid movements in front of and inside the fume hood. This can cause air currents drawing contaminates out of the fume hood.
- Avoid raising the sash(s) too quickly. Raise the sash at a moderate rate and allow the air velocity to increase or the variable air volume system to react to the door movement.
- Never work with sashes set higher than the established working height. Contact safety or air balancing staff if the safe working height is unknown.
- Never work with both sashes open on a walk-in hood. The lower sash is for setup access only.
- Turn on lights. Good illumination will reduce eyestrain.
- Set up apparatus as close to the back as possible. In no case should apparatus be closer than 6 inches (15 cm) from the door.
- Do not block airflow. Raise large object 2 inches (5 cm) off the counter by placing them on blocks. This allows airflow underneath and prevents stagnant areas.
- Never store large quantities of chemicals in the fume hood. Chemical containers block airflow and create unnecessary hazards. Use cabinets designed to store chemicals instead.
- Do not over ride an alarm by manipulating the mute button.
- Clean up chemical spills as soon as possible. Avoid damage to countertops and buildup of large quantities of vapors.
- Ground all electrical equipment.
- Avoid excessive heat within the fume hood. Special hood configurations are available for high heat situations.
- Baffles should be adjusted by qualified airflow experts or safety officers only.
- Perchloric acid hoods should have the wash down system operated at least once per day until a thorough cleaning is accomplished. 5-15 minutes will probably be sufficient depending upon flow rates achieved by the in-duct portion of the system.
- Never allow the area immediately in front of a fume hood in use to become a traffic area. Others walking by the hood face will adversely affect containment.
- Variable Air Volume (VAV) system: Such a system will reduce the amount of temperate air lost to the outside by varying the exhaust volume from the fume hood automatically based on the position of the sash.
- Air flow monitoring devices (alarms): These are available to alert the user that there is insufficient airflow for proper containment.
- A fume hood that is clean and orderly is safer and easier to “shut down” in an emergency, in addition to being more attractive in appearance.
