WARNING!
Hazardous ammonia water solution may escape
If ammonia water solution is batched without
supervision, ammonia water solution can be
pressed out of the system.
– As batching is done in manual mode, the entire
process must be monitored from start to finish.
WARNING!
Hazardous ammonia vapours may escape.
Ammonia vapours will escape if the lid of the
dosing tank is open.
– The lid of the dosing tank must not and may
not be opened.
– The system must be shut down immediately
should the seal be missing on the lid and the
seal must be replaced by an authorised techni‐
cian.
CAUTION!
Only particle-free commercial ammonia water may
be used for batching.
Note for the operator
An explosive atmosphere can form in the supply
drum with concentrations of over 15% w/w and/or
high ambient and media temperatures. If a spark
jumps as the suction lance is approaching the
open opening of the supply drum, it could cause
this atmosphere to explode.
Therefore take appropriate measures, such as the
following:
–
Use an earthing cable to ensure that the suc‐
tion lance and storage tank have the same
potential just before inserting the suction lance
into the storage tank.
–
Use suction lances with a level switch with
explosion protection for Zone 0.
–
Only connect the ammonia water to the system
in its original drum or in an electrically con‐
ducting vessel.
- always refer to the chemical supplier’s latest hazardous sub‐
stance data sheet and the latest regulations and materials safety
data sheets issued by the statutory accident prevention authorities.
