Working in Lab Fume Hoods
Employ these best work practices to maximize safety when using a fume hood.
- Verify Functionality: This includes current certification, ensuring air flow, and checking the hood alarm.
- Use the Sash Properly: The sash should be used as a barrier between you and chemicals inside the hood. Never allow your head to enter the plane of the hood opening. Keep the sash below max operating height (usually 18 inches).
- Be Chemically Aware: Know about the safety concerns for each chemical you use. Refer to your chemical hygiene plan or material safety data sheets.
- Be Electrically Aware: Electrical receptacles (including power strips) must be located outside of the fume hood. Eliminate sources of ignition or sparks when flammable chemicals are present.
- Be Self-Aware: Perform all work and keep all apparatuses at least six inches into the hood. Use personal protective equipment.
- Be Organized: The fume hood is NOT a storage area. This can obstruct air flow, and exacerbate an emergency.
