Working Safely with Laboratory Fume Hoods
- Ensure the exhaust is operating before commencing work.
- Use appropriate personal protective equipment.
- Keep your head outside of the hood.
- Work as far into the hood as possible with slow deliberate movements.
- In case of potential explosion hazards, a blast shield should be utilized.
- If a combination sash is installed, do not open the vertical and horizontal sashes simultaneously.
- Do not remove airfoil or baffles. Doing so would result to airflow disturbance within the hood.
- Do not use the hood as a storage area. Items on the work surface can affect airflow and interfere with containment.
- Do not use the hood's sink for waste disposal.
- Do not let chemicals evaporate in the hood as a means of disposal.
- Do not leave uncapped bottles of chemicals or waste in the hood.
- In case of performance failure or if airflow alarm is triggered, terminate fume hood usage, close the sash completely and cease work.
- Do not use perchloric acid in a conventional fume hood. Explosive perchlorate salts could accumulate in the exhaust system.
- Minimize external airflow disturbances including foot traffic.
- Perform routine maintenance and certification.
