11. Opening this bleed valve WILL release the
substantial amount of liquid NH
3
presently trapped in
the hose, most likely as a spray. Open the valve very
slowly, just until some fluid appears. Leave the valve
just slightly open.
12. Walk away, up-wind. Stay away until the release
concludes. Carefully open bleed valve completely to
confirm hose is discharged. For dual-cooler, repeat
step 9 through step 12 for the other hose.
13. Close all breakaway bleed valves ( x and ),
and any nurse tank hose valves . Disconnect the
nurse tank half of the breakaway coupler at the
Acme coupler .
14. Correct the cause of breakaway, only if trivial to do in
the field.
15. Consult the breakaway manual for re-coupling
instructions.
Before Re-connection: Elevated Exposure Hazard:
Exercise extreme care. Even if the nurse tank is undamaged,
sound and upright, a breakaway event is not a normal re-hitch
situation. A substantial NH
3
bleed is required that WILL
release a flow of liquid anhydrous ammonia under pressure.
If the wind is calm or light, do not attempt to bleed the nurse
tank hose(s). Your field PPE
a
is not sufficient.
