What accessories improve safety in a fume cupboard laboratory?

Fume cupboards, also known as fume hoods, are vital components in laboratory settings, designed to protect personnel from hazardous fumes, vapors, and airborne particles. Ensuring their safety and efficiency involves understanding their design standards, selecting appropriate accessories, and adhering to best practices.

Key Safety Standards for Fume Cupboards

Fume cupboards must comply with specific safety standards to ensure effective containment and protection. The European standard EN 14175 outlines three primary safety objectives:

1. Containment: Prevent hazardous substances from entering the laboratory environment.
2. Purging: Avoid the formation of explosive atmospheres within the cupboard.
3. Splash and Shatter Protection: Protect laboratory personnel from potential injuries due to splashes or flying debris.

Adhering to these standards is crucial for maintaining a safe laboratory environment.

Essential Accessories to Enhance Fume Cupboard Safety

Incorporating specific accessories can significantly improve the safety and functionality of fume cupboards:

• Variable Air Volume (VAV) Systems: These systems adjust airflow based on the sash position, enhancing safety and energy efficiency.

• Continuous Monitoring Devices: Incorporating devices such as magnehelic gauges allows for real-time monitoring of airflow, ensuring optimal performance.

• Splash Guards and Debris Screens: Installing these accessories protects users from potential splashes and flying debris during laboratory operations.

• Flammable Liquid Storage Cabinets: These cabinets are designed to safely store flammable materials, reducing the risk of fire hazards.

Best Practices for Safe Use of Fume Cupboards

To maximize the safety and effectiveness of fume cupboards, consider the following best practices:

• Regular Maintenance and Testing: Conduct annual checks to ensure the fume cupboard operates correctly and complies with safety standards.

• Proper Storage of Chemicals: Store only active-use chemicals inside the fume cupboard, keeping large stock bottles in dedicated storage cabinets.

• Segregation of Incompatible Chemicals: Use compatibility charts to prevent dangerous reactions by storing incompatible chemicals separately.

• Ensure Adequate Ventilation: Laboratory ventilation rates should ensure 8-10 air changes per hour minimum for occupied spaces and 6 air changes per hour minimum when unoccupied.

Conclusion

Selecting the right fume cupboard and associated accessories is essential for maintaining a safe laboratory environment. By adhering to established safety standards, incorporating appropriate accessories, and following best practices, laboratories can effectively mitigate risks associated with hazardous substances.
