Record observations without adjusting the system
If the cupboard alarms or you suspect extraction is not working correctly, stop work safely under your site procedure and notify the responsible laboratory person. Follow the unit’s operating instructions and local emergency arrangements. Do not bypass an alarm, change fan settings or repeatedly reset the controller to continue work.
Our service includes preventative maintenance and repairs to cupboards, fans and ducting. Send observations from a safe position so the team can identify the equipment and plan the appropriate attendance. Avoid opening electrical enclosures, climbing to the fan or attempting internal repairs.
Keep a simple fault record
| Record | Useful detail |
|---|---|
| Equipment | Asset ID, room, model and serial label photograph. |
| Symptom | Exact alarm indication, unusual sound, sash issue or visible damage. |
| Timing | When first seen; constant or intermittent; what happened beforehand. |
| Recent changes | Repairs, room layout, ventilation work or a change in use. |
| Current status | Person notified, restrictions applied and existing service reference. |
Make routine maintenance easier to organise
Keep the manufacturer’s instructions and the building’s compliance schedule with the asset records. Identify the owner of each required task and retain dates, findings and repair documentation. The schedule may require procedures at more than one interval; an annual service reminder is not a complete maintenance plan.
Ask the laboratory contact to coordinate safe access and work-area preparation before attendance. Tell the service provider about contamination concerns and access restrictions in advance. A repair visit and the IQP evidence required for a BWoF are related but separate matters; agree both scopes if both are needed.
Turn a vague request into an actionable enquiry
Instead of “the cupboard is not working”, use a brief such as: “Room B, asset FC-02, airflow indication changed during start-up; work has stopped under our procedure; the room ventilation was serviced this week.” Add a clear photograph of the display if it can be taken safely. This is an illustrative record, not a diagnosis.
After the visit, keep the technician’s findings, work completed, any restrictions and the agreed criteria for returning the unit to service. If further testing or parts are required, nominate a person to follow the matter through. Do not treat disappearance of an alarm as a substitute for the required checks.
