Laboratory Safety Standards Put Fume Cupboard Testing and Maintenance in Focus

Australia, 2026: Maintaining laboratory safety equipment is an ongoing responsibility for organisations operating scientific, educational, research and industrial facilities. Fume cupboards are an important part of laboratory ventilation, but their effectiveness depends on appropriate design, installation, operation and continued performance. Regular fume cupboard testing can help Australian laboratories monitor their equipment and plan maintenance based on measured performance.

Dynaflow's published guidance states that fume cupboards should be constructed and maintained in accordance with the applicable Australian Standard and that their performance should be tested regularly. The company identifies face-velocity and smoke testing as important parts of the testing process.

Understanding the Importance of Performance Testing
A laboratory fume cupboard is designed to capture and remove airborne contaminants generated during laboratory activities. However, simply having a fume cupboard installed does not guarantee that it will continue to perform as intended indefinitely.

Airflow can be influenced by the condition of fans, ductwork, controls, building ventilation and other surrounding factors. Changes to laboratory layouts or the introduction of large equipment can also influence airflow patterns.

This is why fume cupboard testing provides useful information that cannot always be obtained through a visual inspection.

Face-velocity testing measures airflow entering the cupboard, while smoke testing can provide information about airflow behaviour and containment. Dynaflow's published information recommends regular testing of these characteristics.

Testing Frequency Depends on Use
Laboratory managers need to establish testing schedules that reflect how their equipment is used. Dynaflow states that fume cupboards should generally be tested annually and that frequently used cupboards should be tested every six months.

The appropriate schedule can depend on factors such as frequency of use, application, operating conditions and the requirements of the relevant standards and facility procedures.

A planned testing schedule can help prevent performance checks from being overlooked and provides maintenance teams with regular opportunities to review equipment condition.

The Link Between Testing and Maintenance
Testing and maintenance are closely connected. If testing identifies a performance issue, the next step may involve investigating the exhaust fan, ductwork, airflow controls, sash, baffles or other components. Depending on the issue, corrective work may be required before the equipment can return to normal operation.

Dynaflow provides preventative maintenance and repair services covering fume cupboards, exhaust fans, duct systems and fume scrubbers.

A planned maintenance programme can help laboratories address issues systematically rather than waiting for equipment failure to interrupt operations.

Existing Fume Cupboards May Require Upgrades
Older laboratory equipment can present additional considerations. Laboratory technology, ventilation requirements and operational needs can change over time, meaning an older fume cupboard may not necessarily meet the needs of a modern laboratory.

Dynaflow notes that existing fume cupboards that do not comply with applicable requirements may need to be replaced or upgraded as soon as practicable, with the appropriate course of action determined for the equipment and application.

Upgrades may involve controls, airflow systems or other components rather than automatically requiring complete replacement.

Testing can provide useful information when determining whether existing equipment remains suitable or requires further attention.

Accurate Records Support Better Maintenance Planning
Documentation is an important component of laboratory asset management. When testing results are recorded consistently, facility managers can maintain a history of equipment performance.

Dynaflow states that it uses custom testing software to provide consistent, calibrated and auditable testing results. Clients can also access test reports through an online secure database.

For organisations with numerous laboratories, this type of documentation can make it easier to monitor testing schedules and identify equipment requiring maintenance or further assessment.

User Behaviour Also Affects Performance
Even properly maintained equipment requires correct operation. Dynaflow's laboratory guidance recommends keeping the sash at the recommended height, avoiding unnecessary storage inside the cupboard and preventing large equipment from blocking airflow paths. It also advises users to minimise traffic immediately in front of a fume cupboard because movement can create turbulence.

These practical measures can complement formal testing and maintenance programmes.

Laboratory staff should receive appropriate training so they understand how the equipment is intended to be used and what actions to take if an alarm or other fault occurs.

Testing Across Different Laboratory Environments
Australian laboratories operate across a broad range of sectors. Dynaflow provides fume cupboard solutions for universities, schools and colleges, research facilities and mining environments.

Different facilities can require different designs. Dynaflow's product range includes standard laboratory cupboards as well as specialised options for perchloric and hydrofluoric acid applications, low-level radiation work, walk-in applications and accessibility requirements.

Regardless of the application, ongoing performance monitoring remains relevant.

Building a Preventative Approach
A preventative approach to laboratory ventilation can combine several activities: selecting suitable equipment, commissioning it correctly, training users, carrying out routine inspections, completing scheduled fume cupboard testing and responding to identified issues.

This approach gives facility managers a clearer picture of equipment condition and allows maintenance decisions to be based on measured information.

For laboratories operating valuable research equipment or conducting teaching and industrial processes, maintaining dependable ventilation systems can also support operational continuity.

Supporting Laboratory Safety Through Regular Testing
Fume cupboards are an important engineering control in laboratories where hazardous airborne substances may be generated. Their performance should therefore remain an active part of laboratory management rather than being considered only when equipment appears to have failed.

Regular fume cupboard testing, combined with appropriate maintenance and correct user practices, provides laboratory operators with a structured way to monitor equipment performance.

For Australian facilities, understanding applicable standards, maintaining accurate records and arranging appropriate testing can help organisations manage their laboratory ventilation systems over the long term.

As laboratories continue to evolve, regular performance assessment can help ensure that existing equipment remains appropriately maintained and that potential issues are identified before they become larger operational concerns.
