1. Contact EHS to receive fume
hood/ventilation equipment training.
2. Define the hazard level of the
proposed work and locate a unit that meets the standard. Refer to the
yellow certification sticker on the left-hand side of the fume hood for
the velocity. Check the expiration date. Do not use the unit if the
certification is expired. Contact DEHS to certify the unit.

3. Visually check your magnehelic
gauge or audible/visual alarm to verify that the system is operational.
4. Clear the fume hood deck area.
Remove all materials from hood which are not needed for immediate
work.
5. Locate work at least 6 inches (use
a length of tape to mark out six inches) inside the sash and center
relative to the hood sides. This achieves maximum protection and increases
the capture efficiency of the fume hood.

Equipment are to be used in conjunction with the appropriate protective
equipment, such as safety glasses/splash goggles, face shields, lab coats,
and task specific chemical protective gloves.
