Mastering Laboratory Safety: Essential Tips on Working with Fume Hoods

In the dynamic realm of laboratory environments, ensuring the safety of researchers and maintaining optimal working conditions is of paramount importance. Among the various safety measures, one crucial component is the effective use of laboratory fume hoods. These essential pieces of equipment are designed to protect researchers from hazardous fumes, vapours, and particles. In this comprehensive guide, we will delve into essential tips on working with fume hoods to ensure a secure and productive laboratory setting.

Why Opt for a Fume Hood?

When working with volatile chemicals, countless molecules are released into the air. Inhaling toxic fumes is undesirable, considering the potential health risks associated with such exposure.

It's crucial to bear in mind that our interaction with chemicals often occurs chronically, involving prolonged exposure to low levels. Take beta-mercaptoethanol, for instance—a pungent, toxic reducing agent that not only fills the lab with an unpleasant odour but is also deemed hazardous when inhaled, as indicated in the safety data sheet.

Determining when to use a fume hood can be simplified by adhering to a practical guideline. While not every chemical emits a strong odour as a reminder of the need for careful handling (note: not on the bench), a sensible approach is to utilize a chemical fume hood whenever possible. Only deviate from this practice if there is a well-founded reason for not working within one.

Understanding the Importance of Laboratory Fume Hoods:

Laboratory fume hoods play a vital role in maintaining a safe working environment by containing and controlling potentially harmful substances. These devices are designed to prevent exposure to toxic chemicals, minimize the risk of chemical reactions, and protect both personnel and experiments. As laboratories evolve, so do the advancements in lab furniture. Many lab furniture manufacturers now offer modular lab furniture that seamlessly integrates with fume hoods, enhancing the overall efficiency and functionality of the workspace.

Choosing the Right Laboratory Fume Hood:

  1. Evaluate the Lab's Specific Needs:
    Before selecting a laboratory fume hood, it is crucial to assess the specific requirements of the lab. Different experiments and chemicals may necessitate varying types of hoods, such as ducted or ductless fume hoods. Engage with reputable laboratory fume hood manufacturers to discuss your lab's needs and receive expert guidance on the most suitable options.

     2. Consider Ventilation Systems:
Adequate ventilation is key to the effectiveness of fume hoods. Collaborate with lab furniture manufacturers that specialize             in designing modular lab furniture compatible with advanced ventilation systems. Proper airflow ensures the efficient m.                 removal of contaminants, maintaining a safe and comfortable working environment.

Proper Installation and Maintenance:

  1. Professional Installation:
    Once the laboratory fume hood is selected, it is essential to have it professionally installed. Proper installation ensures that the hood functions optimally and adheres to safety standards. Choose experienced technicians or collaborate with laboratory furniture manufacturers that offer installation services for their products.

     2. Regular Maintenance Checks:
         To guarantee the longevity and effectiveness of laboratory fume hoods, establish a routine maintenance schedule. Regular            inspections, filter replacements, and performance checks should be conducted to identify and address any issues p                        promptly. This proactive approach reduces the risk of malfunctions and enhances the overall safety of the laboratory.

Safe Operating Practices:

  • Understanding Airflow and Face Velocity:
    Familiarize yourself with the concept of face velocity – the rate at which air is drawn into the fume hood. Maintaining the recommended face velocity ensures that the hood effectively captures and contains hazardous substances. Work closely with laboratory fume hood manufacturers to understand the specific airflow requirements for your equipment.
  • Proper Placement of Equipment:
    Strategically place equipment within the fume hood to optimize its performance. Ensure that the sash opening is adjusted according to the experiment's needs, and keep the workspace clutter-free to allow for proper airflow. This practice not only enhances safety but also contributes to the efficiency of experiments.

Training and Education:

  • Training for Lab Personnel:
    Prioritize the training of laboratory personnel on the correct usage and safety protocols associated with laboratory fume hoods. Engage with laboratory furniture manufacturers that offer comprehensive training programs to ensure that researchers are well-versed in the proper handling of equipment.
  • Stay Informed on Industry Standards:
    As laboratory safety standards evolve, it is crucial to stay informed about the latest developments. Regularly review and update safety protocols to align with industry best practices. Collaborate with laboratory fume hood manufacturers that prioritize adherence to global safety standards.

Collaboration with Lab Furniture Manufacturers:

  • Seek Expert Advice:
    When planning or upgrading a laboratory, leverage the expertise of lab furniture manufacturers. Reputable manufacturers can provide valuable insights into the integration of modular lab furniture and fume hoods, creating a cohesive and efficient workspace.
  • Customization Options:
    Explore customization options offered by lab furniture manufacturers to tailor the laboratory setup according to specific requirements. Modular lab furniture can be designed to accommodate various configurations, ensuring flexibility and adaptability as research needs evolve.

Fume Hood Tips

Fume hoods boast substantial capabilities for evacuating gases and removing hazardous chemicals from the user's breathing area. Most fume hoods are equipped to supply cold water, vacuum, and nitrogen necessary for conducting experiments. Here are some important considerations to keep in mind when working with a fume hood:

  1. Avoid keeping the sash too high, as this diminishes the hood's ability to evacuate air. Always close the sash when not actively using the fume hood.
  2. Verify the airflow meter to ensure there is sufficient airflow. Check that no obstructions are impeding the airflow through the baffles or exhaust slots.
  3. Maintain the proper sash working height at 46 cm.
  4. Work at least 25 cm inside the hood to ensure effective containment.
  5. Do not obstruct the air slot at the rear of the hood.
  6. Limit the number of objects inside the hood to prevent disruption of airflow.
  7. Minimize foot traffic around the fume hood area.
  8. Wear appropriate safety gear, including safety glasses and gloves.
  9. Always wear safety clothing such as lab coats.
  10. Adhere to safe practices and facility protocols. Check the safety certifications of the fume hood, ensuring it is certified under ASRAE 110.


In conclusion, the proper utilization of laboratory fume hoods is a critical aspect of ensuring a safe and efficient working environment in laboratories. By collaborating with experienced lab furniture manufacturers, selecting the right equipment, and adhering to best practices, researchers can minimize risks and conduct experiments with confidence. As the field of laboratory safety continues to advance, staying informed and embracing innovative solutions from laboratory fume hood manufacturers will contribute to the overall success of scientific endeavours while prioritizing the well-being of laboratory personnel.
