DESCRIPTION OF HAZARDS

Dwelling: 5 storey Victorian mid-terraced house.

Background: The dwelling being assessed is a ground floor flat in a five storey (including basement

and attic) mid terraced house converted into five self contained flats. Entry to the flat, which

comprises a living room at the front of the house and bedroom and kitchen at the rear, plus an

internal bathroom, is from the common hall.

Location of house: The house is located next to a parade of shops on a main arterial road running

out of London. This road provides access to the motorway and is used by heavy goods vehicles as

well as for long distance and local car journeys.

Immediately behind the short rear yard and garden

is the main London to Scotland rail line. The line is used by high speed trains, local diesel trains and

goods trains. The main living room of the flat overlooks the main road and the bedroom and kitchen

the rail line. All windows are traditional single glazed double hung sashes, and many particularly at

the rear are ill-fitting and in disrepair.

There is no way the habitable rooms in the flat can be used without suffering from the

noise caused by the road and train traffic. It would interfere with all activities, including

sleeping patterns. While some people may be more tolerant of traffic noise than others,

the likelihood of it causing some adverse health effects to a typical resident at some

period during a year's exposure would be very high.

Secondary glazing should be fitted to all windows (or double glazing with a sufficient gap

between the panes to reduce noise penetration). However, because of its position, it will

not be practicable to reduce the problem to the average levels.

Despite the likelihood being high, the fact that the noise is largely confined to general

road and rail traffic noise and does not arise from specific disturbances caused by

neighbours, means that the health outcomes are unlikely to any higher than average for

this hazard. However, due to the very high incidence, the HHSRS result is still very high

with a score of 2445 and band B rating.
