Grit, Dust and Effluvia
Emissions of grit, dust and effluvia cause nuisance and where this is serious and persistent it is
generally due to several causes. One premises where trouble has been experienced is the National
Coal Board Depot, West Drayton. Here a number of improvements have been carried out for the
suppression of dust, and a vacuum type road sweeper for the collection of spillage and dust has
been ordered. The difficulty of suppressing dust in this type of depot is perhaps best realised by
noting that fuel storage premises were exempted from the cleanliness provisions of the Offices, Shops
and Railway Premises Act, 1963. Effectively to deal with the nuisance from this depot, a great effort
to improve the methods of handling the fuel, which cause excessive dust, rather than attempting to
suppress the dust is necessary.
Deposit gauges have been used to monitor the dust emitted in the vicinity of the Coal Depot,
West Drayton and the Gas Works, Uxbridge. A table showing the results is set out overleaf. Deposits
are higher than would normally be expected for a fringe London Borough. However, the period of
observation in 1965 was of too short a duration to show whether the position had altered, and
monitoring has been continued in 1966.
