Common Mistakes to Avoid When Using Laboratory Hoods

Laboratory hoods are vital tools for maintaining safety and controlling airborne contaminants in research environments. To ensure optimal usage and safety, it is important to be aware of and avoid these common mistakes when working with laboratory hoods.

Neglecting Proper Training: One of the most common mistakes is using laboratory hoods without sufficient training. Seek training from experienced personnel or consult your institution’s guidelines.

Failing to Check Hood Performance: Neglecting to regularly check the performance indicators and alarms of the laboratory hood is a significant oversight. 

Incorrect Sash Position: Improper positioning of the sash is a common mistake that affects the airflow and containment within the hood. Ensure the sash is at the recommended height to maintain proper airflow patterns and prevent the escape of contaminants.

Overcrowding the Hood: Overloading the laboratory hood with excessive equipment or samples can disrupt airflow and compromise safety. Maintain a clutter-free workspace inside the hood to allow for proper airflow and efficient containment.

Inadequate Personal Protective Equipment (PPE): Failing to wear appropriate PPE is a grave mistake when working with hazardous materials in laboratory hoods. Always use the necessary gloves, lab coats, goggles, and respiratory protection to protect against potential hazards.

Improper Storage: Using laboratory hoods as storage areas for chemicals, equipment, or personal items is a serious violation. Hoods should be kept clear of unnecessary items to maintain proper airflow and prevent cross-contamination.

Lack of Maintenance: Neglecting regular maintenance and cleaning of laboratory hoods can compromise their performance and safety. Follow the manufacturer’s guidelines for maintenance procedures and schedule routine inspections.

By being mindful of these common mistakes and taking the necessary precautions, you can ensure the effective and safe use of laboratory hoods. Remember to consult your institution’s guidelines and seek assistance from experienced personnel or hood manufacturers to address any concerns or questions. Prioritizing proper usage and safety measures will contribute to a productive and secure laboratory environment.

Strategies for Properly Setting Up and Adjusting Laboratory Hoods

Setting up and adjusting laboratory hoods is a crucial step in ensuring their optimal performance and the safety of researchers. Proper airflow management and containment are key considerations when working with these hoods. Here are some strategies to help you set up and adjust laboratory hoods effectively.

Plan the Placement: Carefully consider the placement of the laboratory hood within the lab space. Ensure it is located away from heavy foot traffic, direct sunlight, and sources of vibration to minimize disturbances and maintain a stable environment.

Assess Airflow Requirements: Understand the specific airflow requirements for your experiments and hazardous materials. Consult with experts or refer to guidelines provided by the hood manufacturer to determine the appropriate airflow volume and velocity necessary for effective containment.

Check and Adjust the Sash: The sash is a crucial component of the laboratory hood that helps maintain airflow control and containment. Adjust the sash height to the recommended level, usually around 18 inches, to strike a balance between safety and efficient airflow.

Optimize Airflow Patterns: Laboratory hoods are designed with baffles and airflow indicators to guide the proper direction and velocity of air within the hood. Ensure these components are correctly adjusted to create uniform airflow patterns that prevent the escape of contaminants and maintain containment.

Conduct Smoke Testing: Periodically perform smoke testing to visualize the airflow patterns within the hood.

Regular Maintenance and Calibration: Implement a routine maintenance schedule for laboratory hoods, including cleaning, filter replacement, and inspection of alarms and airflow indicators. 

Document and Communicate: Maintain proper documentation of setup procedures, adjustments, and maintenance activities.

By following these strategies, you can optimize the performance of laboratory hoods, minimize risks of exposure, and create a safe working environment. 


In the world of scientific research, ensuring the safety of both researchers and valuable experiments is paramount. Laboratory hoods play a crucial role in achieving this goal by providing a controlled environment for handling hazardous substances and controlling airborne contaminants. By mastering the art of laboratory hood usage and following best practices, you can safeguard yourself and your research.
