3.5.1 Safely Dealing with Sources of Danger
Information concerning the various forms of danger that can arise during machine operation are found
here.
Electricity
➤ Allow only qualified and authorized electricians or trained personnel under the supervision of a
qualified and authorized electrician to carry out work on electrical equipment according to elec‐
trical engineering regulations .
➤ Before every start-up, the user must make sure there is adequate protection against electric shock
from direct or indirect contact.
➤ Before starting any work on electrical equipment:
Switch off and lock out the power supply disconnecting device and check that no voltage is
present.
➤ Switch off any external power sources.
These could be connections to floating contacts or electrical machine heating, for example.
➤ Use fuses corresponding to machine power.
➤ Check regularly that all electrical connections are tight and in order.
Forces of compression
Compressed air is contained energy. Uncontrolled release of this energy can cause serious injury or
death. The following information concerns work on components that could be under pressure.
➤ Close shut-off valves or otherwise isolate the machine from the compressed air system to ensure
that no compressed air can flow back into the machine.
➤ Vent all pressurized components and chambers completely.
➤ Do not carry out welding, heat treatment or mechanical modifications to pressurized components
(e.g. pipes and vessels) as this influences the component's resistance to pressure.
The safety of the machine is then no longer ensured.
Compressed air quality
➤ Never directly inhale compressed air.
➤ Use appropriate systems for air treatment before using the compressed air from this machine as
breathing air and/or for the processing of food products.
➤ Use food-grade cooling oil whenever compressed air is to come into contact with food products.
Spring tension
Springs under tension or compression represent contained energy. Uncontrolled release of this en‐
ergy can cause serious injury or death.
Minimum pressure/check valves, safety relief valves and inlet valves are powerfully spring-loaded.
➤ Do not open or dismantle any valves.
Rotating components
Touching the fan wheel, the coupling or the belt drive while the machine is switched on can result in
serious injury.
➤ Do not open the enclosure while the machine is switched on.
