Abschnitt 3 - Risks

In principle, there is a danger that people can be run over by a transfer car. In addition there is a crushing and shearing risk for persons standing between the conveyor and the transfer car. These risks arise in particular upon sudden entry into the danger zone at the side of the conveyor.

Using laser scanners does not always guarantee the detection of persons due to blurring within the outer scanning area. Risks may also occur due to incorrect adjustment and programming of the scanner.

The area between the conveyor and the transfer car is extremely dangerous.

After major modifications or extensions of existing plants a risk assessment has to be carried out in accordance with the → § 3 Ordinance on Industrial Safety and Health. Should this risk assignment result in new or additional risks this is a case of an essential modification as defined in → § 4 Equipment and product safety act. Consequently, the EC conformity procedure has to be carried out for the complete installation.

After modification of an existing plant this has to be considered as a new installation with regard to safety precautions if the following conditions have been met:

  1. 1.

    The modifications lead to new risks that cannot be avoided by means of the already existing protection devices respectively by additional simple separating guards.

  2. 2.

    A risk analysis has shown that due to the modification of the plant irreversible personal injuries will occur with high probability.

New or additional risks might for example be the result of a significant increase of the moving speed of the transfer car whereas just an exchange of the conveyors on the transfer car will not lead to a danger increase.
