5.3 Changing the suction lance
Personnel:
Protective equipment:
DANGER!
It is essential that the personal protective equipment (PPE) described on the
product data sheet (safety data sheet) for the metering medium is used.
CAUTION!
Hazard from the use of incorrect chemicals
When changing suction lances, there is a risk of mixing up suction hoses and
thus using the incorrect chemicals.
– If several suction lances need to be changed at one station at the same
time, we recommend that the chemical canisters and associated suction
hoses are marked accordingly before disconnecting the connections.
– When changing several suction lances at one station, always finish working
on one suction lance before moving on to another to avoid confusion.
CAUTION!
Risk of accidents with dosing chemicals!
If the connections of the suction tube and the return line are reversed, an
accident with dosing chemicals can occur due to overpressure in the metering
system:
– For suction lances with a return connection, do not mix up the suction line
and return line.
CAUTION!
Danger of slipping on wet floors
Liquids leaking in the working and preparation area can cause slipping and
injuries.
– Wear non-slip, chemical-resistant shoes when working
– Shut off the area of the escaping liquid
– Duly absorb any liquids escaping during work
– Keep a suitable container ready to collect the liquids during maintenance
work
1.
If necessary, insert the pressure tube of the delivery pump into a sufficiently large
collecting basin.
2.
Provide a suitable container of lukewarm water.
3.
If necessary, unscrew the suction lance adapter from the container connection.
4.
Carefully pull the suction lance out of the container.
