LAYOUT DESIGN Figure 1 Option 1

5.1 The range of fitting out components contained in

this HTM has been developed to cater for most layouts
and all the configurations described in BS EN
14056:2003.

5.2 Workstation layouts can be wall-related, peninsular,

island or a combination of the three.

5.3 The use of machine benches for cumbersome

analytical and processing equipment is strongly
recommended. Access to the backs of some machines
may be required for maintenance, in which case braking
castors should be fitted.

5.4 Mobile workstations and mobile sink units may be

used in conjunction with all options.

5.5 Guidance regarding layout and ergonomic data for

benches and storage is contained in BS EN 14056:2003
and HBN 15 – ‘Facilities for pathology services’.

5.6 Consultation should take place with fire officers,

radiation protection advisers, statutory bodies and other
relevant specialists regarding layouts. Subsequent
rearrangement or change in use may require approval.

DESIGN OPTIONS 5.13 Drainage is either through flexible pipes to floor

points or hard-piped to the perimeter wall.
5.7 A variety of design options can be arrived at using
the component and service arrangements described. 5.14 Adaptation is by laboratory staff in conjunction with
local plumbers, with little disruption to the work of the

ranges

8.1 Where a manufacturer offers a complete range of

the components described in this HTM made to its own
design, the architect should require that test certificates
be produced showing compliance with the requirements
of this HTM together with a detailed product
specification.

8.2 The use of this method of procurement could result

in incompatibility of units if more than one manufacturer
is used.
