KEY TO THE MECHANICAL RISKS CAUSED BY MOVEMENT
Pursuant to the Machinery Directive:
“Danger zones” refer to any zone within and/or
around machinery in which an exposed person is
subject to a risk to his or her health and safety.
“Exposed person” refers to any person wholly or
partially in a danger zone.

ANALYSIS OF THE RISKS AND CHOICE OF SOLUTIONS
IN ACCORDANCE WITH THE MACHINERY DIRECTIVE 98/37/EEC AND THE STANDARDS EN 13241-1, EN
12453, EN 12445
The risks listed below follow the sequence of the installation process. These risks are those which are commonly
present in motorised doors/gates systems. According to the various situations, consideration therefore has to be
made of any possible additional risks and exclude those which are not applicable. The solutions to be adopted are
those indicated by the standards mentioned above; in the case of risks not dealt with, the safety integration
principles indicated by the Machinery Directive (Annex 1 – 1.1.2) have to be applied.

Mechanical, structural and
wear risks.
[1] Loss of stability and
break-up.
[2] Tripping.
F
Check the solidity of the structure installed (jambs, hinges and leaves) in
relation to the forces generated by the motor.
Attach the motor stably using adequate materials.
If available, check the content of the EC declaration of conformity of the
manual gate.
F
If necessary, carry out the structural calculation and attach it to the
Technical File.
F
Check that the travel of the leaves is limited (during opening and closure)
by mechanical stops of adequate strength.
Check that the leaves cannot, under any circumstance, exit their slide guides
and fall.
F
Check that any thresholds higher than 5 mm are visible, indicated or
shaped.
