3.5.1 Safely dealing with sources of danger
The following describes the various forms of danger that can occur during machine operation.
Electricity
➤ Allow only qualified and authorised electricians or trained personnel under the supervision of a
qualified and authorised electrician to carry out work on electrical equipment according to elec‐
trical engineering regulations.
➤ Before commissioning or re-commissioning the machine, the user must ensure adequate pro‐
tection against electric shock from direct or indirect contact.
➤ Before starting any work on electrical equipment:
Switch off and lock out the power supply isolator and verify the absence of any voltage.
➤ 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 proper condition.
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 distribution network to ensure
that no compressed air can flow back into the machine.
➤ De-pressurise all pressurised components and enclosures.
➤ Do not carry out welding, heat treatment or mechanical modifications to pressurised compo‐
nents (e.g. pipes and vessels) as this affects the component's resistance to pressure.
The safety of the machine is 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 foodstuffs.
➤ Use compressor oil compatible with foodstuffs if compressed air can come into contact with
them.
Spring forces
Springs under tension or compression store energy. Uncontrolled release of this energy can cause
serious injury or death.
Solenoid valves and check valves are spring-loaded.
➤ Do not open or dismantle any valves.
Rotating components
Touching the fan while the machine is activated can result in serious injury.
➤ Do not open the enclosure while the machine is activated.
➤ Switch off and lock out the power supply disconnecting device and verify the absence of any
voltage.
➤ Wear close-fitting clothes and a hair net if necessary.
