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.
