1,200 linear metres of
laboratory benches
were provided and
planned with differing
under-counter options
LABORATORY
CONTROL PANEL AT LABORATORY ENTRANCE
are held in dedicated stores and cabinets.
Gas stores are located at ground level and
are naturally ventilated. These stores are fitted
with gas sensors. Gas cylinders are placed
on earthed mentis grating to prevent the risk
of ignition.
Long term chemical storage is remote from
the building and storage for daily use is provided
in the laboratories.
External risks in the surroundings ie: nitrogen
storage tanks are managed by sensors linked
to air-intakes which are shut down in event
of leaks. A hydrogen storage tank has been
relocated and oxygen relief valve on an adjacent
plant has been redirected. Air-flow modelling
on the building around the exhausts from
the fume hoods was undertaken to manage
risks of fumes and exhaust gases affecting
neighbouring buildings.
Within the laboratories, full emergency
stations with emergency showers and safety
equipment are provided in the corridors.
Eyewash stations were omitted in favour of
sterilised eyewash bottles at localised areas.
Where required, class 16 light fittings are
provided. Chemicals are stored (on drip trays)
at low level to obviate the risk of dropping
containers and spillage.
