| MCMAHON Services
were called to this unique project due to their expertise in building
decontamination, however the contamination source was somewhat different
to usual.
Pigeons had began to nest in the ridge cap
of the 6,000m² building as a result the droppings, bird feathers
and faeces contaminated the building with lice and there was a risk
contamination could spread a disease called Fungus Cryptococcus
neoformans and could contain the fungus Histoplasma capsulatum,
which can be transmitted to humans by airborne spores. If transmitted
to a human it could become a fatal disease.
As a result of the contamination the work shops
and store were closed and McMahon Services crew worked around the
clock for a 6 day period to decontaminate the building.
Decontamination was carried out by personnel
with Tyvec coveralls and respiratory protection. We utilised our
trailer mounted Hepa filtration vacuum cleaner and small industrial
vacuums to vacuum every surface within the complex. All areas were
then wet wiped with a disinfectant.
2200 man hours were spent decontaminating the complex with no lost
time incidences.
The project also involved the redesigning of
the buildings vent ridge and installation of a new one to prevent
pigeons infiltrating the building in the future.
