DESCRIPTION OF HAZARDS

Dwelling: Pre 1920, ground floor flat

Background: The dwelling is a ground floor flat in a three storey building with a commercial premises also

on the ground floor, and a flat on each of the first and second floors. Access to all the flats is via a foyer on

the ground floor. There is separate access to the ground floor commercial premises. The ground floor flat

comprises a living room, kitchen, bathroom and two bedrooms (see plan above). The external walls are of

stone, and the internal walls are of plastered brick; the floors are suspended timber. All the windows to the

flat are timber-framed, west facing, and are of a large size. None of the windows have any openable area

and all have secondary glazing (there is no overshadowing). The kitchen and bathroom both have

mechanical extract ventilation. There is a gas fired central heating installation comprising of a combination

boiler in the kitchen with radiators in all rooms and the flat hallway. Each radiator has standard control

valves which are "stuck" on open. The thermostat is in the hallway.

The provision of openable windows to all living spaces (with security catches) or

alternatively the incorporation of a properly designed system of mechanical ventilation will

ensure that temperature build-up in the summer months can be avoided and should reduce

the likelihood of an occurrence to the average. Repairing the radiator valves would help

control tempartures in different parts of the dwelling during the heating season.

Justification

RATING

Lack of ventilation in the living and bedrooms together with large areas of glazing will mean

the flat will become uncomfortably warm during late afternoon and early evening in the

summer months (but not be as great as it would be for a south facing property). Avoiding

high temperatures during the heating season is possible by lowering the thermostat.

However, in summer, the likelihood of exposure to excessive high temperatures is higher

than average.
