WARNING!
Danger from hazardous substances!
Possible consequence: Fatal or very serious injuries.
Please ensure when handling hazardous substances
that you have read the latest safety data sheets provided
by the manufacture of the hazardous substance. The
actions required are described in the safety data sheet.
Check the safety data sheet regularly and replace, if
necessary, as the hazard potential of a substance can
be re-evaluated at any time based on new findings.
The system operator is responsible for ensuring that
these safety data sheets are available and that they are
kept up to date, as well as for producing an associated
hazard assessment for the workstations affected.
The hydrazine solution is batched semi-automatically. The operating per‐
sonnel use the manual stirrer to create a homogeneous solution.
The metering pump meters the hydrazine solution via the injection valve
into the desired pipework. Metering can be precisely controlled via the
external control of the metering pump.
The vapour recovery line permits transfer within a closed system. The dis‐
charge air filter breaks down escaping hydrazine into ammonia. A bleed
line transports the ammonia out of the building.
The operator of the system must use a collecting pan or other suitable
measure to prevent hydrazine from discharging into the environment in the
event of a leak. The operator of the system may wish to attach a leak
probe etc. to the collecting pan to trigger an alarm.
