A fume cupboard is one of the most essential pieces of safety equipment in any laboratory. Its primary function is to protect users from hazardous fumes, vapors, and dust by capturing and exhausting them through proper ventilation. To ensure both safety and efficiency, modern laboratories must follow international standards and implement best practices in the selection, installation, and use of fume cupboards.
1. Compliance with Safety Standards
Fume cupboards must meet internationally recognized standards such as EN 14175 (Europe) or ANSI/ASHRAE 110 (United States). These standards define performance requirements for airflow, containment, and filtration. Compliance ensures that the cupboard provides consistent protection under real working conditions.
2. Proper Airflow and Face Velocity
The performance of a fume cupboard depends largely on airflow. A common benchmark is maintaining a face velocity between 0.4–0.6 m/s to contain hazardous substances without creating turbulence. Airflow should be continuously monitored, and alarms should alert users if levels fall below the required range.
3. Chemical Resistance and Durability
Materials used in fume cupboards must withstand aggressive chemicals, solvents, and heat. Powder-coated steel frames, laminated or compact laminate panels, and polypropylene or ceramic components are commonly chosen for their durability and resistance. Using the right materials extends the lifespan of the equipment and ensures long-term safety.
4. Best Practices for Users
Safe operation also depends on user behavior. Laboratory staff should always:
- Keep the sash at the recommended working height.
- Avoid placing equipment too close to the front opening.
- Minimize rapid movements that may disrupt airflow.
- Perform regular cleaning and maintenance.
5. Maintenance and Testing
Routine inspections and annual performance tests are vital. Airflow calibration, filter replacement, and structural checks should be part of a scheduled maintenance program. A well-maintained fume cupboard not only protects staff but also reduces energy consumption.
Conclusion
Fume cupboards are central to laboratory safety. By adhering to international standards, choosing durable materials, and following best practices in operation and maintenance, laboratories can create a secure and efficient environment for research and experimentation.
