State of the art
Appendix I, Chapter 1.1.2 of the Machinery Directive 2006/42/EC prescribes a
clear procedure and sequence for the selection of protective measures. The
procedure is as follows:
Eliminating or minimising the hazards
This takes place at the design stage of the machine. These measures include,
for example:
● A reduction in the use of energy (power, revolutions, voltages etc.) as far
as this is possible
– The avoidance of unnecessary sharp points or sharp edges
– The avoidance of human errors by means of the ergonomic and log‐
ical design of operating devices
– The avoidance of hazardous materials and commodities
Taking protective measures against hazards that cannot be eliminated
These measures include, for example:
● Guards (railings, housings, guards)
● Protective devices (light barrier for hazard elimination)
● Protective control equipment (enabling devices and eanbling buttons, two-
hand controls, speed monitoring etc.)
User information about residual hazards
This last of the three options is used if residual hazards remain after the first
two options have been applied. These measures include, for example:
● Warning notices
● Training and organisational measures
● The use of personal protective equipment
The technical construction file contains all the documents that are required to
prove the safety of the machinery / safety component. These are, for example:
● A complete drawing of the machinery or safety component including con‐
trol circuit diagrams
● Hazard and risk analysis
● Calculations
● Research and test results
● A list of the basic safety requirements of the Machinery Directive applica‐
ble to the machine and a description of the solutions
● Used standards
● Operating instructions,operating manuals
The technical construction file must be retained for a minimum of 10 years after
the supply of the last product, and must be presented within a period of a few
days in the event of a claim for damages.
This means technical possibilities at a certain point of time that are based on
certain scientific and technical knowledge. The state of the art also means
something that is commercially viable, that is it can be realised by the majority
in the industrial sector concerned.
The state of the art is defined as the state of development of advanced proce‐
dures, equipment or operating methods, that makes the practical applicability
of the measure appear assured overall in respect of the targeted goals (e.g. the
goals of protection of work, protection of the environment, safety of third parties
