Fume Cupboard Best Practices: How to Use Your Laboratory Fume Cupboard Safely

When it comes to laboratory safety, following fume cupboard best practices is essential. Whether you’re in research, education, or pharmaceuticals, correct usage ensures compliance with UK regulations, protects staff, and keeps your workspace efficient. At The Fume Cupboard Company Ltd, we support laboratories across the UK in achieving safer working conditions.

Best Practice Guidelines for Fume Cupboards

1. Position Equipment Properly

Always keep chemicals and glassware at least 150mm (6 inches) inside the sash opening. This simple step improves containment and ensures effective fume capture.

2. Confirm Airflow Before Starting Work

Before use, confirm that airflow is within safe operating levels. Use airflow monitors, alarms, or a simple smoke test. For further guidance, visit the HSE’s COSHH regulations.

3. Minimise Clutter in Your Workspace

Avoid storing unnecessary items inside. Excess equipment blocks airflow and compromises containment. For chemical storage solutions, see our laboratory furniture options.

4. Lower the Sash for Maximum Protection

The lower the sash, the greater the protection. Keep it at the recommended working height (usually 400–500mm). This acts as a barrier while maintaining good user access.

5. Always Wear PPE

Even when working inside a fume cupboard, PPE remains vital. Gloves, lab coats, and eye protection reduce exposure risks and should always be worn.

FAQs on Fume Cupboard Use

Q: What is the correct working height for a sash?
Most fume cupboards include a safe working height marker, usually 400–500mm.

Q: Can a fume cupboard be used for chemical storage?
No. They are not designed for long-term storage. For advice on safe alternatives, see COSHH chemical storage guidance.

Q: How often should fume cupboards be tested?
In the UK, COSHH regulations require testing every 14 months. High-use labs may need more frequent inspections. Learn more about our LEV testing services.

Q: Do fume cupboards protect against all hazards?
No. They provide protection against chemical vapours, gases, and particulates but not physical hazards, explosions, or certain biological risks.

Q: What should I do if the airflow alarm is triggered?
Stop work immediately, close the sash, and notify your supervisor. Do not resume until the system has been inspected.
