Laboratories are dynamic environments where safety must always come first. The fume cupboard stands out as a vital tool in protecting lab personnel and maintaining a safe work area. In this, we’ll explore how fume cupboards contribute to safety by containing harmful fumes, preventing exposure, and ensuring the smooth operation of laboratory processes.
What Is a Fume Cupboard?
A fume cupboard, also known as a fume hood, is a ventilated enclosure used to control the exposure of laboratory personnel to hazardous fumes, vapours, and dust. These units are designed to contain and exhaust toxic or harmful substances, preventing them from entering the laboratory environment and exposing researchers and staff to potential risks.
Fume cupboards serve as an essential line of defence against the dangers associated with handling chemicals. They are not only found in academic and research institutions but are also commonly used in hospitals, pharmaceutical labs, industrial laboratories, and chemical manufacturing facilities. Their primary role is to ensure that workers can safely perform experiments or processes without risking their health or the overall laboratory environment.
Why Fume Cupboards Are Essential in Laboratory Safety
Fume cupboards play a significant role in protecting laboratory personnel from harmful exposure to chemicals, especially in labs where toxic, flammable, or corrosive substances are frequently used. Here are some key reasons why fume cupboards are crucial in ensuring laboratory safety:
Containment of Hazardous Fumes
Fume cupboards are specifically designed to contain and remove hazardous fumes from the laboratory environment. Whether dealing with volatile chemicals or conducting processes that release harmful vapours, fume cupboards help prevent these substances from spreading within the lab. Without adequate ventilation, fumes can cause respiratory problems, irritation, or even long-term health risks.
Protection From Chemical Splashes and Spills
While fume cupboards are primarily designed to manage airborne hazards, they also provide a barrier against accidental splashes or spills of chemicals. The enclosed workspace allows laboratory personnel to handle dangerous materials with an added layer of protection, reducing the likelihood of direct contact with hazardous substances.
Ventilation and Air Quality Control
Fume cupboards maintain a controlled airflow, drawing air away from the user and through the system’s ventilation. This not only prevents the inhalation of harmful substances but also helps maintain overall air quality within the laboratory. By removing dangerous fumes and replacing them with clean air, fume cupboards create a safer working environment.
Fire Hazard Reduction
Laboratories that handle flammable substances are at higher risk of fire-related accidents. Fume cupboards are designed to minimise this risk by safely containing volatile chemicals and their vapours. In the event of a fire within the fume cupboard, the containment and ventilation features help to control and prevent the spread of flames.
Minimising Environmental Contamination
Laboratories often work with substances that, if improperly handled, could harm the environment. Fume cupboards help minimise the risk of releasing harmful chemicals into the air or surrounding areas. By containing and exhausting fumes through proper filtration systems, these units reduce the environmental impact of hazardous laboratory processes.

Whether you need a standard unit or a custom solution, we are committed to delivering fume cupboards that ensure the safety and productivity of your laboratory environment.
Proper Usage of Fume Cupboards
To maximise the effectiveness of fume cupboards, it’s vital that laboratory personnel use them correctly. Improper usage can greatly reduce their protective benefits. Here are some key tips:
Keep the sash at the recommended height: The sash helps contain fumes and maintain airflow. Keeping it at the correct height ensures the cupboard works effectively.
Avoid overcrowding the work area: Too many items inside the cupboard block airflow and reduce ventilation efficiency. Keep the space clear for optimal performance.
Position equipment and materials properly: Place items at least 15 cm from the front edge and avoid blocking the back airflow to maximise containment.
Ensure regular maintenance and inspection: Regularly check airflow and filters to maintain performance and safety. Neglecting maintenance can lead to safety risks.
