2.12 Residual risks
Residual risks are special hazards involved in the use of the machine which cannot be
fully eliminated despite a safety-conscious design. These residual risks are not readily
recognizable and may result in injury or damage to health.
In the event such unforeseen residual risks become apparent, the machine must be
shut down immediately and the responsible supervisor informed accordingly (if applic-
able). The supervisor then makes any further decisions and initiates the necessary
measures for elimination of the hazard. If required, the machine manufacturer must be
informed.
2.13 Hazards caused by mechanical influences
DANGER
During operation of the machine, there is mortal danger from uncovered rotating
machine parts (drive shafts, shafts, rollers, and conveyor belts...) and attached
parts jutting out.
Rotating machine parts and breaking attached parts may cause the serious injuries
such as contusions, loss of body parts, broken bones. These injuries may be deadly in
especially severe cases. During lifting, within range in front of the machine there is the
greatest danger to life from stones or other objects possibly flung away (for instance,
detaching metal parts).
– You can protect yourself against these hazards by maintaining a sufficient safety
distance, by constant attention and by wearing suitable protective clothing.
2.14 Hazards caused by electricity
DANGER
Danger of death due to electric voltage.
Cables and components are live, there is a danger of injury with deadly conse-
quences. Clamping points are under voltage also after shut-off.
– All work on the electrical equipment of the machine must always be carried out by
qualified electricians.
– Check electrical equipment on a regular basis: refasten loose connections and
replace damaged lines and cables immediately.
There is an electrical hazard during work on the machine:
During direct contact with live parts or parts that have become energized due to
fault conditions.
By electrostatically charged parts.
During all work on live parts, lines or cables, a second person must be present,
who turns off the main switch in an emergency case.
Never clean electrical equipment with water or similar liquids.
Do not touch live parts inside and outside the machine.
Before beginning work on the machine, switch it off at the main switch, make sure
that no voltage is present and secure it from unintentional restart.
Before opening cabinets and devices, discharge all parts that collect electrical
charge, and make sure that all components are de-energized.
