DESCRIPTION OF HAZARDS
Dwelling: Basement letting in a 4 storey house
built in 1906
Background: The property is a large Edwardian detached family residence that has been converted into
student accommodation. The building itself comprises a basement area containing kitchen, common room
and 4 study bedrooms. There is a reception area and 10 study bedrooms on the ground floor plus bar and
dining area. The first and second floors contain 12 study bedrooms. A paved route at the basement area
gives access to rooms located there whilst at ground floor level there is a car park specifically for use by
students residing in the building. Access to the to the basement path from the car park is via stone steps
leading down, the steps are bounded on one side by a wall approximately 325mm in height above ground
level. The car park itself is separated from a path surrounding the house by a low brick wall 400mm in height
and capped by stone flags. The car park is approximately 100mm below the level of this path so that on the
path side the wall is 300mm in height. There is one light to the far side of the car park from the property and a
movement sensitive security light on the house wall overlooking the path around the house.

Justification
There is an increased likelihood of a member of the vulnerable agre group falling over the
low car park wall and the low wall at the top of the steps. The inadequate lighting means
that the likelihood is greater during hours of darkness. This justifies a significant increase in
likelihood as the hazard is unusual and unexpected.

Justification
The fall although not a great distance will be on to unforgiving surfaces and hard edges
such as the step, thereby increasing the chance of worse than average Class I, II and III
harm outcomes.
