Control systems
18.—(1) Every employer shall—
(a)ensure, so far as is reasonably practicable, that all control systems of work equipment are safe; and
(b)are chosen making due allowance for the failures, faults and constraints to be expected in the planned circumstances of use.
(2) Without prejudice to the generality of paragraph (1), a control system shall not be safe unless—
(a)its operation does not create any increased risk to health or safety;
(b)it ensures, so far as is reasonably practicable, that any fault in or damage to any part of the control system or the loss of supply of any source of energy used by the work equipment cannot result in additional or increased risk to health or safety;
(c)it does not impede the operation of any control required by regulation 15 or 16.
