Safety of Machinery
Overview
Risk assessment
safety of people or the environment are excluded. Such products can be dis‐
allowed by member states in their sovereign territory.
In order that free movement of goods may also be guaranteed for these prod‐
ucts, the national safety regulations of the member states are harmonized by
means of European Union Directives.
These Directives exist for different product classes, e.g. machines, medical
products or also toys. However, Directives have also been compiled for fur‐
ther common product safety aspects, such as protection from electricity and
explosion, and electromagnetic compatibility (EMC).
The Directives are aimed at the member states, whose task is to convert
them into national law. Therefore the Directives have legal character.
"CE" marking certifies that the manufacturer fulfils all obligations in relation to
the product on the basis of the EU Directives. The CE mark is the "passport"
within the EU and is defined on behalf of the supervisory authorities.
Additionally independent, accredited notified bodies can be commissioned to
carry out an EC type-examination and draw up a certificate.
Both the Electromagnetic Directive (EMC Directive 89/336/EEC) and the Ma‐
chinery Directive (MD 2006/42/EC) are applicable to the Hand-Held Termi‐
nals.
Additional measures must be taken wherever faults arising in the machinery
may cause personal injury or significant material damage. These measures
must also guarantee a safe operating condition for the whole system in the
event of a fault.
Although the Hand-Held Terminal is not, in the narrower sense, a machine, it
does, however, perform important tasks to guarantee the safety functions of a
machinery to which it is attached.
The Hand-Held Terminal features, for example, the "Emergency Stop" safety
function and an enabling device for use in special operation modes. It is, as a
result, a "Safety Component" in terms of the Machinery Directive (MD).
Safety components, i.e. parts whose failure or faulty operation put the safety
of people within the danger zone of the machine in danger, fall expressly
within the range of application of the Machinery Directive (MD). The funda‐
mental requirements that the Machinery Directive places on the manufacturer
are as follows:
●
To perform a hazard and risk analysis
●
To comply with the integration of safety principles
●
To compile and keep a technical construction file
●
To provide solutions according to the latest state of the art
●
Presumption of conformity with harmonized Standards
●
To apply CE marking (on the type plate)
Basically, the same requirements apply to safety components. In their partic‐
ular case, it must be proven that failure or malfunction are not possible, or
that malfunction does not lead to a hazardous situation.
The manufacturer of a machine is obliged to perform a risk assessment of the
machine. Risk assessment comprises risk analysis and risk evaluation. The
machine must be analyzed throughout its whole operating life and in all oper‐
ation modes, and all hazards that may possibly arise must be documented.
This has to be done without taking into account possible safeguards.
