3.3 Regulations for the prevention of accidents
When carrying out works such as solar installation work
it is necessary to do so in a safe and workman like man-
ner, taking due care of any aspects of the works that
could result in injuries to person in or about the building
as well as workers, passers by and the general public at
large. To that end these works must conform, but not be
limited to, the current regulations in force such as the
following
— Health and Safety at Work act 1974
— Work at Height Regulations 2005.
— Electricity at Work Regulations 1989
— All necessary Building Regulations.
Work should be preceded by a risk assessment covering
all aspects of health and safety risks, or training re-
quirements that can reasonably be foreseen to be asso-
ciated with the work. All scaffolding in the UK, other
than prefabricated (zip-up) scaffold towers, must be de-
signed and constructed by a vetted contractor, and
have suitable kick boards, hand rails and where appro-
priate netting. Areas around the scaffolding should be
zoned off and marked with suitable warning signs to a
suitable distance to protect persons from falling objects.
Workers should have available and use personal protec-
tive equipment as necessary. This would include equip-
ment such as fall protection systems, safety gloves,
goggles, dust masks as well as any specialised equip-
ment that may be in use such as lifting and handling
equipment.
The completed works shall comply with all necessary
BS EN Standards and Codes of practice as well as Build-
ing control or planning requirements and be confirmed
where necessary by notification to building control or
the appropriate competence based notification body.

If there is a sarking membrane, proceed as follows:
• Cut the sarking membrane vee-shaped.
• Fold the upper, larger tab on the roof batten above,
and the lower, smaller tab on the roof batten below.
• Fix the sarking membrane tight to the roof batten.
This ensure that the dampness flows away to the side.
• With the roofs activated, cut out a hole with the com-
pass saw.
• Work the roofing felt as described for the sarking
membrane.
