17 Do the air velocities achieve the standardappropriate for the type of canopy? (UCV theatres only)

18 Measure and record the room differentialpressures (all areas served by ventilation system)

19 Do the room differential pressures ensure a flow of air from the clean to the less clean areas? (all areas served by ventilation system provided with pressure/air flow cascade)

20 Measure and record the noise levels in theprincipal rooms of the suite (all areas servedby ventilation system)

21 Do the noise levels fall below the limits set out in Table 2 of health Technical Memorandum 03-01, Part B? (all areas served by ventilation system)

22 Check the operation of all ventilation controlfunctions represented on the surgeon’spanel. (also applies to other highdependency medical locations)

23 Do the indicators accurately represent theoperational state of ventilation system(s)? (also applies to other high dependency medical locations)

24 For UCV systems: is the UCV and AHUinterlocked to ensure that the AHU runs at full speed when the UCV is at operating speed or at set-back? (see Table 6 in Health Technical Memorandum 03-01, part A) (UCV theatres only)

25 With the UCV running at set-back, does thesystem maintain the standard of a conventional operating room? (UCV Theatres only)

26 For all theatres: with the system running atset-back, does it maintain a flow of air fromthe clean to the less clean areas? (allventilation systems with two speed/multispeed or set back ventilation)

1. Clarity of test:a. Particle challenge has been taken at the supply grille in the Anaesthetic room for this

theatre suite.b. Sampler at 1 meter above floor level.c. The centre measurement should be taken with the detector head mounted vertically

upwards, 1 meter above floor level.d. The number of intermediate test positions should be as equally spaced as possible around

the periphery, with no fewer than three and no more than five complete test squares between test positions.

where necessary.7 Confirm the safety closure operation of the fire damper

according to the manufacturer’s instructions.8 Confirm operation of damper to OPEN and CLOSE by use

of the control system and physical observation of the damper, rectify and report where necessary.

21– Test Equipment Used

Clarity of calibration – The measuring instrument should be a hotwire anemometer with a digital read-out. The instrument resolution should be at least 0.01 m/s, have a tolerance of ±0.015 m/s or 3% of the reading and be calibrated down to 0.15 m/s or lower. An alternative instrument may be used, providing it is of no lesser specification.
