Introduction to Health and Safety at Work

17.26.15 Stability – Regulation 20
Work equipment must be stabilized by clamping or other-
wise as necessary to ensure health and safety.
Most machines used in a fi xed position should be 
bolted or fastened so that they do not move or rock 
in use.
17.26.16 Lighting – Regulation 21
Suitable and suffi cient lighting, taking account of the 
operations being carried out, must be provided where 
people use work equipment.
This will involve general lighting and in many cases 
local lighting, such as on a sewing machine. If access 
for maintenance is required regularly, permanent lighting 
should be provided.
17.26.17
Maintenance operations – 
Regulation 22
So far as is reasonably practicable work equipment 
should be constructed or adapted to allow maintenance 
operations to be:
➤
conducted while they are shut down
➤
undertaken without exposing people to risk
➤
carried out after appropriate protection measures 
have been taken.
17.26.18
Markings and warnings – Regulations 
23 and 24
Work equipment should have all appropriate 
markings
for reasons of health and safety made in a clearly visible 
manner. For example, the maximum safe working load, 
stop and start controls, or the maximum rotation speed 
of an abrasive wheel.
Work equipment must incorporate 
warnings
or 
warning devices
as appropriate, which are unambigu-
ous, easily perceived and easily understood.
They may be incorporated in systems of work, a 
notice, a fl ashing light or an audible warning. They are 
an active instruction or warning to take specifi c precau-
tions or actions when a hazard exists.
