DESCRIPTION OF HAZARDS
Dwelling:
1920s semi-detached house
A) Lead paint: There have been a few improvements and alterations to the house. However,
repainting of internal woodwork has not included removal of the original paint and the main lead
water supply pipe has not been changed. Much of the internal decoration is worn and peeling, the
paint to internal woodwork is chipped in parts and repainting is needed.
B) Lead pipes: The water supply pipe serves the cold water tap over the sink and the electric water
heater. The dwelling is in a rural area, and water supplies are known to be plumbo-solvent.

RATING
The internal woodwork is in need of repainting, which, in view of its condition, would
involve removal of the old paint down to the bare wood. Without appropriate precautions
being taken, this could release old lead-based paint dust and fumes into the dwelling.
This combined with the contamination of the water supply would dramatically increase
the likelihood of an occurrence. (Without the old paint, the likelihood would be around 1
in 56.)

Due to the substantial amount of lead-based paint remaining present and exposed in all
rooms, the chance of a serious outcome is increased.

The old paint should be stripped by a competent person using proper protection. The
occupants should be temporarily rehousing during the stripping and re-painting. The
lead pipework should be removed and new plastic or copper pipes installed.
