How to Choose the Right Fume Hood and Its Applications

Fume hoods protect laboratory personnel from hazardous vapors and dusts. Understanding their applications helps in making the right choice.

Fume Hood Applications:

• Chemistry Labs: Standard fume hoods for general chemical handling.
• Perchloric Acid: Special perchloric acid fume hoods with wash-down systems.
• Radioisotope Work: Lead-lined fume hoods for radioactive materials.
• Clean Rooms: HEPA-filtered fume hoods for particulate-sensitive work.

Usage Guidelines:

• Keep sash closed when not in use.
• Do not block air intake slots at the bottom.
• Conduct annual face velocity and smoke pattern tests.
• Maintain minimum face velocity of 100 fpm at working height.
