DESCRIPTION OF HAZARD
3 bedroomed 1850 mid terrace house
Background - This 3-bedroomed early Victorian house was modernised in the 1970s. In this
modernisation, the original external door to the south facing back addition was made into a window
and a new back porch/lobby was constructed to give a new back door and internal access to the
original outside w.c. compartment. At the same time, a new bathroom with a bath and wash hand
basin, but no w.c, was installed at first floor level in the small back addition above the kitchen.
Subsequently, central heating was also installed, including the installation of a radiator in the
otherwise cold ground floor w.c. compartment.
Ground floor w.c: Despite the modernisation, the narrow downstairs w.c. compartment was left
without a wash-hand basin. Although the compartment's single leaf brick wall was rendered
externally, the floor was also never adequately damp-proofed, the consequent rising damp leading to
the lifting and subsequent break up of the thermo plastic floor tiles. The lid to the wc is also now
missing.

Ideally, a w.c. needs to be installed in the first floor bathroom, if necessary by replacing
the bath with a shower. Alternatively, the existing w.c. compartment could be rebuilt to
modern building regulation standards. The new compartment would need to be wide
enough to accomodate a new wash hand basin as well as any re-positioned radiator.
This would reduce the HHSRS score to average.

RATING
With no wash-hand basin on the ground floor and the upstairs bathroom being the
furthest possible walking distance in the house away, anyone using the ground floor w.c.,
particularly children, are likely to forego washing their hands. The inconvienent location
of the w.c. and its extreme separation from the w.h.b. is also likely to have some
physcological effects. The related risk of washing hands in the nearby sink is scored
under food safety, while the unhygienic floor to the w.c. compartment is scored under
domestic hygiene.

While the likelihood of infection is increased, there is nothing to suggest that the
outcomes should be changed from the average. However, with the high likelihood this
still gives an HHSRS score of 522 and a band rating of D-.
