3.7.10 Oil-sealed vacuum pump: hazards caused by hot and contaminated vacuum
pump oil
WARNING
Risk of scalding caused by the vacuum pump oil
When working on the vacuum pump and exhaust gas filter (especially
when changing the oil or filter), the maintenance personnel are exposed to
the hot vacuum pump oil.
There is a risk of scalding in the event of skin contact.
• Wear suitable protective clothes and gloves!
• Use a suitable collecting vessel!
WARNING
Risk of poisoning/infection caused by the vacuum pump oil
When working on the vacuum pump and exhaust gas filter (especially
when changing the oil or filter), the maintenance personnel are exposed to
the vacuum pump oil, which may contain harmful substances originating
from the product. In addition, synthetic oils can release toxic fumes when
they are ignited or heated above 300°C.
The inhalation of the fums that are released by the oil, or contact with the
skin, can cause severe damage to health.
• Wear suitable protective clothes, gloves, and respiratory protection!
• Ensure the environmentally sound disposal of the oil in compliance
with the local rules and regulations!
• Do not let the oil come into contact with tobacco products!

3.7.11 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!
