there is no digital display, check by measuring the temperature of the air outlet under the cooling unit
with a probe thermometer.
1.4 Gas cylinders
Gas cylinders are heavy, even when empty. They should be chained or clamped to a wall or other stable
structure when upright and chocked when horizontal on the floor, with the bottom of the cylinder placed
against a wall.
Ensure that suitable securing points are provided at temporary bars.
CO
2
is heavier than air and if there is a leak the CO
2
will gradually displace the air at the bottom of a
cellar. CO
2
is odourless and a leak may not be detected straight away. Frost on the outside of the
cylinders or valves may be an indicator of a leak. All cellars should have a CO
2
monitor.
In underground cellars where large amounts of CO
2
are stored, an undetected CO
2
leak could be very
dangerous, and there should be means of audible and visible warnings fitted outside the cellar. Consult
your brewery supplier for more advice.
1.5 Pest control
Cellars and stores can provide access points and harbourage for rats and mice. Ensure that all bars
and cellars are included on the unit’s pest control contract.
The pest control contractor should check all areas at reasonable intervals, usually every 4 to 6 weeks.
They should check and monitor all bar areas, even if these are not in regular use, to ensure there are
no access points and no potential of harbourage.
Remove redundant equipment and waste material as this can provide a good area for rats and mice to
nest.
Rats and mice may not be interested in beers as a food source, but they will be interested in other
beverages such as cider, and food snacks such as sweet confectionery, chocolate, nuts, crisps and
biscuits. Regularly check all food stocks for signs of damage such as gnawing. Ideally store these
products in suitable durable containers with lids. If there is any evidence of pest activity potentially
contaminated foods must be discarded.
Make sure that the room structures are sound, that there are no gaps under doors, that broken windows
are repaired or boarded and that walls and ceiling are made good to surrounds where service and
delivery pipes pass through. Mice can enter through the tiniest gaps or holes.
Be particularly vigilant when alterations are being carried out such as installation or diversion of a new
python. The surrounding walls or ceiling should be made good immediately.
Expanding foam is satisfactory as a temporary filler to holes but rats and mice will eventually gnaw
through this, so a permanent finish is required as soon as possible.
Report any activity to your pest control company immediately – do not wait for the next routine visit and
follow the escalation process in relevant Good Hygiene Practice (GHP 2: Pest Control). Pest activity
must also be reported on AIR.
Flying insects attracted to unattended spillages and waste residues left in drip trays and in sinks can
become a nuisance. Ensure good cleaning standards are maintained at all times.
