3. The Provision And Use Of Work Equipment
Regulations 1998.
• WORK EQUIPMENT means any machinery,
appliance, apparatus, tool and assembly of
components arranged to function as a
whole. It embraces everything from a hand
tool to a complete factory.
• USE means starting, stopping,
programming, setting, using transporting,
repairing, modifying, maintaining, servicing
and any related expressions.

concentrate on
Regulation 11, Dangerous
parts of machinery
9. Regulation 11, Dangerous Parts Of Machinery
Measures shall be taken to:
• Prevent access to any dangerous part of
machinery or rotating stock bar.
“stock-bar” means any part of a stock-bar
which projects beyond the head-stock of a
lathe.
• Stop movement of dangerous parts or stock
bars before any part of a person enters a
danger zone.
• NOTE reference to a person means any part
(e.g. hand, foot or immediate clothing) and
could be either intentional or unintentional
(e.g. a fall) or deliberate (e.g. clearing a
11. Hierarchy of measures:
• Fixed guards, enclosing dangerous parts
• Protective devices or other guards (e.g.
interlocked guards)
• Protective appliances (e.g. jigs, holders and
push sticks
• Information, instruction, training and
supervision (in that order) to the extent
that each is practicable
12. Principles of machine safety:
• Identify the hazards
• Eliminate/reduce the hazards by design
• Use safeguards
• Use SWP’s
13. Machine Guarding is a matter of life and
death:
• In 2016/17 there were 15 fatal injuries in the
manufacturing industries.
• 5 of these were due to contact
with machinery.
• 1 was due to a worker being struck by
an object.
• In the manufacturing industries during the
same period there were also 782 non-fatal
specified (major) injuries due to contact with
moving machinery or being struck by an
object and 2461 over-seven-day injuries
attributable to the same causes.
15. Perimeter guarding with electrical interlocks
• Category 1 can also lead to a loss of the
safety function.
• Category 2 circuits detect faults by
periodic testing at suitable intervals (the
safety function can be lost between the
periodic tests).
16. Perimeter guarding with electrical interlocks
• Category 3 circuits ensure the safety
function, in the presence of a single fault,
for example by employing two (redundant)
channels, but a loss of the safety function
can occur in the case of an accumulation
of faults.
17. Perimeter guarding with electrical interlocks
• Category 4 circuits ensure that the safety
function is always available even in the
case of one or more faults, usually by
employing both input and output
redundancy, together with a feedback
loop for continuous monitoring of the
outputs
18. Emergency stops
• Stop category 0: stopping by immediate
removal of power to the machine
actuators (uncontrolled stop);
• Stop category 1: a controlled stop with
power available to the machine actuators
to achieve the stop and then removal of
power when the stop is achieved;
• Stop category 2: a controlled stop with
power left available to the machine
actuators.
