Why is UCV testing and servicing required?
Post-operative infection is proportional to the level of airborne contaminates within an operating room. To minimise infection risk, many procedures, e.g. in orthopedic theatres, are carried out under an ultra-clean ventilated canopy (UCV). Regular verification, testing and servicing carried out by our experienced UCV specialists ensures the safe and efficient operation of your UCV system. Our system inspection assesses and verifies compliance to existing guidance (HTM 03-01). Should any part of the ventilation system, AHU, filters, ductwork, dampers, fans, speed controllers etc. show non-conformity, actions can be implemented in order to maintain the UCV’s ability to provide clean air and reduce infection risk.
How often does it need to be done?
HTM 03-01 guidance requires verification every 12 months. However, experience, good operational practices and OEM recommendations indicate that verification every 6 months is essential for maintaining optimal safe UCV theatre air quality.
How can AirisQ help with UCV compliance?
Our team of trained and qualified surveyors and engineers who are experienced with UCV systems will service, verify performance and take corrective actions via remedial works, to aid compliance with original design for all makes of UCV canopy systems.
An example of remediation would be:
- Removing any failing HEPA canopy filters in-situ, supplying and installing new.
- Carrying out full integrity testing (by DOP method and in accordance with ISO 14644-3:2005).
- Rebalancing where required to achieve the desired balance and pressure for each quadrant.
- Completing a theatre suite re-verification including grid tests measurements.
- Issuing completion verification report and certification.
Benefits of relying on AirisQ for your UCV servicing
No loss of operating time
By optimising the performance of the canopy and prolonging HEPA filter life.
Minimising infection risk
By optimising the performance and efficiency of the canopy and maintaining adequate wound site velocities.
Compliance documentation
To satisfy infection control team and external auditors
What does UCV Servicing involve?
PRELIMINARY CHECKS
- Magnehelic gauge readings (Pascals, mm wg or inches)
- Fan run voltages (volts) and currents (amps)
- Sound levels (dba)
- Light levels (lux).
SERVICE TASKS
- Cleaning intake grilles
- Removing pre-filters and cleaning behind as required
- Inspection of fan unit(s) for excess noise or vibration
- Failing each fan unit and checking the fail system operates
- Supplying and replacing UCV pre-filters
- Lowering diffuser door to check the following:
- physical condition of the terminal HEPA filters
- tension of any fixings
- any obvious signs of damage or filter bypass
- inspecting the function of UCV theatre and remote panel’s switches and lamps
- checking function of UCV lighting
- reporting on the general condition of the equipment.
PERFORMANCE CHECKS
- Recording of theatre temperatures under UCV and external to UCV.
- Recording velocities under UCV in accordance with HTM guidance: i.e. 100 points at 2.0m ffl and 36 points at 1.0m ffl
- Recording supply and extract volumes to ucv canopy and/or whole theatre suite normally via the room diffusers and/or duct if easily accessible
- Carrying out laser particle counting checks under the UCV (optional)
- Carrying out microbiological air sampling (optional)
- Recording differential pressures between theatre(s) and ancillary areas
- Advising and reporting on any necessary rebalancing of supply or extract air.
