DESCRIPTION OF HAZARDS
Raised inspection chamber in lawn to rear
garden (above and left)
Slope of rear garden shown top left and
left
Dwelling: Two storey house, built 1987
Background: This is a mid-terraced, two storey house comprising a lounge and kitchen/diner at ground floor level
with two bedrooms and a bathroom/WC at first floor level. The front and rear external doors both have low level
thresholds and there are no other matters in relation to trips and slips in the house itself that are any different from that
expected in a house of this age in a typical condition. However, the rear garden which is laid mainly to lawn is steeply
sloped over the rear quarter of the overall garden depth, dropping some 920mm vertically over a horizontal distance of
around 1850mm. In addition, there is a raised inspection chamber cover in the flat section of lawn some 600mm beyond
the rear edge of the patio at the rear of the dwelling. This projects around 70mm above the ground level.

Justification
Changes to the design of this garden are not warranted although the inspection chamber should be reduced in height to
remove the trip hazard at the top of the slope. Other changes would be difficult, e.g. fencing off would make
maintenance difficult and terracing it and adding steps handrails and guarding would be disproportionate to the hazard
reduction that would be achieved.

Justification
Other than the slope to the rear garden, there are nothing to suggest that this house is significantly worse than average
in respect of Falling on stairs etc. However, this Hazard includes falling on ramps and slopes, and the slope is steep (in
the order of 1:2 or 22.5 degrees) with a change in level of more than 300mm. The use of this part of the garden by a
member of the vulnerable age group is more likely to result in a harmful fall, the steepness increasing the risk of a loss
of balance. The raised inspection chamber cover also increases the likelihood of a trip and fall down the slope.

Justification
There is nothing to suggest that the spread of harms should be changed from the average, although the hazard is
external it is not an essential route that would be used at night so that an elderly person falling might remain
undiscovered. The surface on to which a person would fall is also somewhat forgiving
