Edwards EDS 300

DANGER: LIGHTNING STRIKE
Risk of re and injury from lightning strike. The operator is responsible for assessing the
hazard potenal when used outside of buildings.
2.3 Thermal hazards
CAUTION: HOT SURFACES
Burning of ngers, hands or arms on hot surfaces. Handle the pump only when venlated
and cooled down. Wear suitable protecve equipment.
Scalding by contact with hot equipment or lubricants. Danger of scalding when opening
the hot pump with hot operang uid or cooling-water. Only open the outlet or inlet port
for operang media if the operang medium has adapted to the room temperature.
Wear suitable protecve 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 decomposion of pumped gases.
Uncontrolled emission of process gases by reacon products within the pump. The
pumping of reacve gases, vapours or gas mixtures is generally prohibited. The operator
is responsible for assessing the hazard potenal of the process media or mixtures.
Danger of escaping or eming pumped hazardous gases, vapours or substances. Pumped
process gases may escape from the exhaust and leaks in the vacuum system. The
pumping of pyrophoric / radioacve / oxidizing gases or gas mixtures, as well as the
pumping of oxygen of more than atmospheric concentraon (21 %) is generally
prohibited. The operator is responsible for assessing the hazard potenal of the process
media or mixtures.
2.5 Explosion hazard
DANGER: INTERNAL EXPLOSION
The pump is suitable for use with internal and external ammable atmospheres as
dened by the pump marking. There is a risk of internal explosions within the pump, or
ignion sources externally, if the pump is operated outside of the limits of operaon.
