Take special precautions with storage and metering. The specific
potential danger and resulting hazards should be taken from the
current material safety data sheet for the substance used.
Danger of explosion
n
Risk of explosion due to trapped ammonia-air mixtures.
A potentially explosive ammonia-air mixture (lower explosion limit
15.4 vol.%, upper explosion limit 33.6 vol.%) can form in the inte‐
rior of the metering vessel and also in the interior of the supply
drum via the liquid phase depending on the temperature and con‐
centration of the commercial ammonia water product.
The built-in level switch in the metering vessel is therefore
designed to be intrinsically safe “i” with an explosion-proof design.
Pay attention to any static charge when connecting or replacing a
supply drum!
Turn the Emergency Stop switch to “0” in the event of an emer‐
gency or if liquid escapes from the system during pumping.
Refer to the material safety data sheet for ammonia water supplied
by the chemical supplier in the event of any accidents with
ammonia water.
If ammonia water escapes, evacuate the room, put on protective
equipment, seal the leak and, if necessary, collect the escaped sol‐
ution and dispose of!

The “GESTIS Substance Database” published by the IFA Institute
for Occupational Health and Safety of the German Social Accident
Insurance provides valuable information.
Direct contact with ammonia water may occur when changing over
the supply drum and during maintenance work. Observe the
instructions.
Emissions of ammonia gas are not expected due to the gas-tight
design of the storage tanks and the downstream exhaust air
adsorber. This is the case providing the adsorber is regularly
changed.
