3.7.12 Dry-running vacuum pump: hazards caused by contaminated exhaust air
WARNING
Danger of poisoning/infection due to contaminated exhaust air
The exhaust air may contain harmful substances originating from the
product.
Contact with particles in the exhaust air (especially by inhalation) may
result in severe damage to health.
• Use a silencer with integrated filter elements or – depending on the
product
– guide the exhaust gases from the outlet of the vacuum pump
to a suitable treatment system in order to prevent the discharge of
harmful substances into the surrounding atmosphere! Compliance with
the national rules and regulations for the protection of the environment
must be ensured!
• When working on the vacuum system (and especially on the vacuum
pump), it may be necessary to wear suitable protective clothes,
gloves, and respiratory protection depending on the product!
3.7.13 Hazards caused by noise
WARNING
Risk of noise-induced hearing loss
Depending on the local conditions, a harmful sound pressure level may
occur.
High sound pressure levels can cause noise-induced hearing loss.
• Wear suitable personal hearing protection if necessary!
3.7.14 Hazards caused by the loading door
WARNING
Risk of crushing caused by the movement of the loading door
Due to its relative high mass, the movement of the loading door can
hardly be slowed down or stopped.
There is a risk of crushing of body parts between the door and the front of
the chamber.
• Move the loading door slowly holding the door handle when opening or
closing it. Do not hold the door leaf by its edge!
• Lock the door by turning the door handle!
3.7.15 Hazards caused by shelves
DANGER
Risk of crushing caused by the movement of the shelves
The shelves can be moved upwards/downwards by hydraulic force. In
addition, the shelves may sag down in an uncontrolled manner in the
event of a malfunction of the hydraulic system.
There is a risk of crushing of body parts under and between the shelves.
• Do not reach into the chamber while the shelves are in movement!
• Do not manipulate, remove, or disable the two-hand-control of the
shelf movement system or the door contact switch (if available) in any
way!
