DESCRIPTION OF HAZARD/S
Dwelling:
Early 1960's, semi-detached non-trad house
A) Kitchen floor: The main photograph shows the kitchen floor looking through an internal door.
Throughout the kitchen, the original thermoplastic plastic tiles have become unstuck due to rising
damp through the concrete sub-floor and have also become brittle and broken with age. The
remaining floors in the dwelling, although similarly damp on the ground floor, do not present any
additional risk. In addition (although not shown in the photgraphs) there are unsealed joints around
the service entry points, and, because of the form of construction, potential harbourage within the
wall structure, although no current infestation.

RATING
The extent of the hazard fault and its location increases the likelihood of a major
occurrence significantly above that for the average for this hazard. The possibility of the
spillage of food and the dampness, together with the difficulties of cleaning, increase the
likelihood of the harborage of insects, cockroaches etc, and the risk of infection,
particularly to young children. The joints around service entry points will allow access for
pests, and the wall structure will also provide harbourage.

The original thermoplastic tiles should be removed and the floor sealed to prevent further
rising damp. An appropriate impervious finish should be provided. In addition, the joints
around the service entry points should be effectively sealed. However, because of the
type of construction, it would not be practicable to seal all the entry points or remove the
harbourage in the wall structure.

Although, for the reasons stated above, the likelihood of a major infection occurring is
much higher than the average for this category of hazard, there is unlikely to be any
significant change in the spread of health outcomes.
