Lab Ventilation and Fume Hood Safety

Strong safety culture is necessary wherein the highest priority is given to best practices and employee safety. The air inside the laboratory is considered to be harmful to your employees’ health and equipment. The chemicals released in the form of hazardous fumes, vapors, and radioactive materials can deteriorate the health of the lab workers. Lab ventilation systems are essential in creating a safe working environment.

Controlling the ventilation and air quality can be a challenge when planning a positive lab environment. The best way to overcome this is by installing a fume hood ventilation system.

Purifying air inside labs:

  • Install a high-quality SEFA certified fume hood ventilation system.
  • Make sure the fume hood is clean of clutter.
  • Get into a habit of closing the sash when not in use and keep it low during experiments.
  • Ensure the vents and ducts have not been blocked.
  • Close the doors and windows when the fume hood is in use.

In a laboratory, the fume hood is a device that protects employees using flammable or toxic substances.

Things to remember BEFORE using a fume hood:

  • Make sure you have basic knowledge or training of using a fume hood beforehand.
  • I hope you are well-aware of the chemicals you are working with.
  • Ensure that the fume hood is switched on and its airflow is within the desired range.
  • Open the sash to a proper operating level as dictated by arrows on the frame.
  • Check whether the air gauge that determines the airflow is within a certain range.
  • Foster lab workers to wear required protective equipment.

Things to remember WHILE using the fume hood:

  • Prevent airflow blockages by removing all large equipment at least by 2 inches above the base of the hood interior.
  • Heat generating equipment like hot plates, Bunsen burners, and toxic chemicals should not be placed near the rear of the hood.
  • Hazardous chemicals like perchloric acid and radionuclides should be used in a specifically designed hood.
  • All the materials inside the hood should be kept 6 inches away from the sash opening.
  • Make it a habit of closing sash after working inside the hood.

Lab Ventilation and Fume Hood Safety

Responsibility of a Laboratory Supervisor

  • Regular housekeeping is very important to verify that the fume hood is working satisfactorily.
  • Keep a check on the reading of the Magnehelic gauge or electronic display, whichever available.
  • Make sure your sash is working accurately to reduce the possibility of a potential reaction, fire or explosion.
  • Fume hoods should not be used for storing equipment.
  • Make sure that the employees conduct their experiments within around 6 inches inside the hood.
  • Airfoil needs to be installed correctly so that there is a proper streamline of airflow into the hood.
  • Ensure there are fewer sources of air movements in the front.
  • Maintain a high level of housekeeping routine.
