DESCRIPTION OF HAZARDS
Reception room window and kitchen

Floor Plan of utility area, reception
room and kitchen (left)
Dwelling: Two storey, mid terraced, pre-1920 house
Background: This is a traditional two storey house built around 1905, comprising two rooms, a kitchen and a utility
area on the ground floor and two rooms and a combined WC/bathroom on the first floor. The dwelling originally had an
L-shaped footprint but the rear yard area has been enclosed to form a utility area, used mainly for storage. This is to the
rear of the rear room and to the side of the kitchen and encloses both rooms. There is a back door within the rear wall
of the utility area providing access to the rear garden. The rear room is south-facing and has a pvc-u double glazed
window, the opening transom casement of which opens out into the utility area. There is no other means of ventilation to
this room. The kitchen window is in the rear wall but there is a fully glazed, internal door in the side wall which opens
out into the utility area and across the opening arc of the window to the rear room. The glazing to this door is obscured,
non-safety glass.

Providing a limiter to the opening transom (and providing additional and alternative means of ventilation if necessary)
and replacing the glazing to the door from the kitchen with safety glass would reduce the likelihood and spread of harms

Justification
There is increased likelihood of a harmful occurrence because of the low level casement and the proximity to the
thoroughfare through the utility room. Opening the kitchen door would hit the comer of the window, which is likely to be
left opened as it is the only means of ventilation to the room. A child pushing the door open would not see the potential
collision, and this could lead to the glazing in the door breaking or the child walking into the glazing when the door stops
suddenly against the open window .

Justification
The possibility that a small child pushing the door open might collide with and break the non safety glass, and the
potential injuries to the limbs or head, justifies increasing the Class III harm.
