Essential health and safety requirements
1.1 - General considerations / 1.1.2 - Principles of security integration
(c) When designing and constructing machinery and when drafting the instructions, the manufacturer or his authorised representative must take into account not only the intended use of the machinery but also reasonably foreseeable misuse.
1.2 - Control systems / 1.2.1 - Safety and reliability of control systems Control systems must be designed and constructed in such a way as to prevent the occurrence of hazardous situations. In any case, they must be designed and constructed in such a way that: a failure in the hardware or software of the control system does not create dangerous situations, errors in the control system logic do not create dangerous situations.
Particular attention requires the following:
the machinery must not start unexpectedly, the parameters of the machinery must not change uncontrollably, where such a change may lead to dangerous situations, the machinery must not be prevented from stopping, if the stop order has already been given
