Australia, 2026: Laboratory safety continues to be an important consideration for universities, schools, research organisations, mining operations and industrial facilities working with hazardous chemicals and airborne substances. As laboratories become increasingly specialised, maintaining effective containment and ventilation systems is an essential part of responsible laboratory management. Regular fume cupboard testing can help laboratory operators verify that their equipment is performing as intended and identify potential issues before they affect day-to-day operations.

Fume cupboards are designed to capture and remove airborne hazardous substances generated during laboratory procedures. These substances can include toxic or harmful fumes, vapours, gases, dust and chemical aerosols. Dynaflow explains that fume cupboards are widely used across laboratories, schools and universities to reduce the risk of exposure to hazardous substances during laboratory experiments.

While installing an appropriate fume cupboard is an important first step, ongoing performance needs to remain part of a laboratory's safety programme. Ventilation performance can be affected over time by changes to exhaust systems, airflow conditions, equipment, building arrangements, mechanical components and general wear. This makes routine inspection and testing an important consideration for facilities responsible for laboratory safety.

Testing Goes Beyond a Visual Inspection
A fume cupboard may appear to be operating normally while its actual airflow performance requires attention. This is why fume cupboard testing involves more than simply checking whether the fan is running or whether the sash moves correctly.

Dynaflow states that fume cupboard performance should be tested regularly, with face-velocity testing and smoke testing forming part of the assessment. Its information on Australian laboratory requirements refers to AS/NZS 2243.8 and the need for regular performance testing.

Face-velocity testing provides information about airflow entering the working area of the cupboard. Smoke testing can also provide useful information about airflow behaviour and containment. Together, these tests can help identify conditions that may not be obvious during a routine visual inspection.

For laboratory managers, this information can provide a more practical understanding of how a fume cupboard is performing rather than relying solely on its age or appearance.

Supporting Universities and Research Facilities
Universities and research facilities can have particularly demanding laboratory environments. Different departments may use fume cupboards for different applications, with some facilities handling chemicals requiring specialised containment and exhaust arrangements.

Dynaflow supplies several types of fume cupboards for laboratory environments, including its GRP range, which is designed for chemistry research and teaching laboratories. The company also supplies specialised models for applications involving perchloric and hydrofluoric acids, low-level radiation and other specific laboratory requirements.

Regular testing becomes particularly relevant when laboratories operate continuously or when multiple users share the same equipment. Dynaflow's published guidance states that frequently used fume cupboards should be tested every six months, while its general guidance identifies annual testing as a standard interval.

Laboratory managers should consider the nature and frequency of use, the equipment's condition and applicable requirements when establishing a testing schedule.

Identifying Problems Before They Become Disruptive
One of the practical benefits of routine testing is the ability to identify potential performance issues earlier. A change in airflow can have several possible causes, including problems with exhaust fans, ductwork, controls or other components of a ventilation system.

Testing results can help maintenance teams determine whether further investigation or corrective work is necessary. Dynaflow also provides repair and preventative maintenance services for fume cupboards, exhaust fans, duct systems and fume scrubbers.

This approach can help laboratories move away from relying exclusively on reactive repairs. Instead, testing can become part of a planned maintenance programme that supports equipment reliability and laboratory continuity.

The Importance of Correct Fume Cupboard Use
Testing is only one part of laboratory safety. Correct user behaviour also contributes to effective fume cupboard operation. Dynaflow recommends keeping unnecessary items out of the cupboard, maintaining the sash at the recommended height and avoiding the placement of large equipment that could interfere with airflow. It also advises users to minimise unnecessary movement in front of the cupboard, as traffic can create turbulence.

These operational practices are important because even a properly maintained ventilation system can be affected by poor use. Laboratory managers can therefore combine regular testing with user training and clear operating procedures.

A More Structured Approach to Laboratory Safety
For Australian laboratories, fume cupboard testing can form part of a broader approach to managing hazardous substances and laboratory ventilation. Regular performance checks can provide documented information about equipment condition and help facilities identify where maintenance, repair or upgrades may be appropriate.

Dynaflow states that it provides testing and maintenance services using custom testing software designed to produce consistent, calibrated and auditable results. Test reports can also be made available to clients through its online system.

As laboratory environments continue to evolve, maintaining existing ventilation infrastructure can be just as important as selecting new equipment. A structured testing programme gives laboratory operators a practical way to monitor performance and plan maintenance based on measured results.

For organisations responsible for laboratory safety, regular testing, appropriate maintenance and correct user practices can work together to support safer and more reliable working environments.
