15.16.3 Prevention and control of exposure – regulation 7 The employer is required to ensure that exposure of their
employees to hazardous substances is either prevented
or, where this is not reasonably practicable, adequately
controlled.
In determining adequate control, the employer
should give preference to avoiding the use of hazardous
substances by substituting them with a safer alternative
which either eliminates or reduces the risk to health and
safety, so far as is reasonably practicable.
Where prevention of exposure is not reasonably
practicable, the employer is required to apply the follow-
ing protection measures in order of priority:
➤
The design and use of appropriate work processes,
systems and engineering controls and the provision
and use of suitable work equipment and materials
➤
The control of exposure at source, including ven-
tilation systems and appropriate organisational
measures
➤
The provision of suitable personal protective equip-
ment (PPE), where adequate control cannot be
achieved. PPE should be provided in addition to the
above measures.
The protection measures should include:
➤
Arrangements for safe handling, storage and trans
-
port
➤
The adoption of suitable maintenance procedures
➤
Reducing to the minimum required for the work:
➤
The number of employees subject to exposure
➤
The level and duration of exposure
➤
The quantity of substances present at the
workplace
➤
The control of the working environment including
general ventilation
➤
Appropriate hygiene measures including adequate
washing facilities.
