What is a Chemical Fume Hood?

Chemical fume hoods are a type of local exhaust ventilation unit designed to protect lab users from harmful toxic fumes or vapors generated from a broad range of applications.

What is the Function of a Chemical Fume Hood?

These ventilation units, when adequately maintained, become one of the most reliable engineering controls present in research and development labs.

Chemical fume hoods protect workers, products, and experiments by:

  • Drawing vapors, fumes, dust, and gases generated within the lab and removing them from the laboratory. The unit vents the exhaust out into the atmosphere to protect the users and the facility
  • Hoods contribute to laboratory ventilation and improve air quality
  • The unit’s sash shields workers and helps prevent injuries from splashes and fires that may occur inside the hood

The Dangers of not Providing Proper Calibration Maintenance

Preventative maintenance services reduce deterioration of components and lower the risk of compromising worker safety from exposure to harmful chemicals or vapors.

Regularly scheduled maintenance of chemical fume hoods prolongs the life expectancy of the unit, thus protecting the company’s investment.

Additionally, properly calibrated and maintained hoods are critical for laboratories to remain compliant with local, state, and federal regulatory agencies.
