DANGER: LIGHTNING STRIKE
Risk of fire and injury from lightning strike. The operator is responsible for assessing the
hazard potential when used outside of buildings.
2.3 Thermal hazards
CAUTION: HOT SURFACES
Burning of fingers, hands or arms on hot surfaces. Handle the pump only when ventilated
and cooled down. Wear suitable protective equipment.
Scalding by contact with hot equipment or lubricants. Danger of scalding when opening
the hot pump with hot operating fluid or cooling-water. Only open the outlet or inlet port
for operating media if the operating medium has adapted to the room temperature.
Wear suitable protective equipment.
A barrier must be placed around the pump to prevent accidental contact with hot
surfaces. The barrier must not only consist of barricade tapes or warning signs. The
barrier must be reliable and require tools (such as screwdriver or allen key) for removal.
2.4 Danger through materials and substances
DANGER: HAZARDOUS GASES
Danger due to a rapid increase in pressure due to the decomposition of pumped gases.
Uncontrolled emission of process gases by reaction products within the pump. The
pumping of reactive gases, vapours or gas mixtures is generally prohibited. The operator
is responsible for assessing the hazard potential of the process media or mixtures.
Danger of escaping or emitting pumped hazardous gases, vapours or substances. Pumped
process gases may escape from the exhaust and leaks in the vacuum system. The
pumping of pyrophoric / radioactive / oxidizing gases or gas mixtures, as well as the
pumping of oxygen of more than atmospheric concentration (21 %) is generally
prohibited. The operator is responsible for assessing the hazard potential of the process
media or mixtures.
2.5 Explosion hazard
DANGER: INTERNAL EXPLOSION
The pump is suitable for use with internal and external flammable atmospheres as
defined by the pump marking. There is a risk of internal explosions within the pump, or
ignition sources externally, if the pump is operated outside of the limits of operation.
