Ammonia Emergency Action
▲ Have a plan. Execute the plan.
Expect the possibility of exposure or uncontrolled release in
any phase of setup, transport or operations. Have contact
information at hand. Know the wind direction at all times.
▲ Act Quickly:
Training matters.
You must know what to do, and act without hesitation.
▲ Move or Turn Up-Wind:
The first priority is to avoid exposure, or stop further
exposure. On splash or spill, get out of the vapor cloud.
Move up-wind.
If a leak is detected while operating in the field, turn the
tractor into the wind, lower the implement into the ground
and perform an emergency flow shut-off. Pull the rope.
If a breakaway occurred, move the tractor some distance
upwind from the disconnected nurse tank.
▲ Apply First Aid:
Treat exposures with water flushing (and only water or
saline solution, unless instructed otherwise by a physician).
Irrigate continuously. Get professional medical help as
soon as possible.
Do not stop with one flush. Apply water until a physician
takes over or instructs otherwise. In particular, do not use
lotions, ointments, salves or creams. They can trap the
harmful agents under the skin.
▲ Close Valves Only if Not in Vapor Cloud
Once clear of the cloud, evaluate if it is safe to close any
shut-off valves not already closed.
DO NOT re-enter vapor cloud.
DO NOT attempt leak/spill control other than valve closure.
If Raven SCS 450 console is on, set MASTER switch off.
Do not turn POWER switch off.
▲ Escape:
Continue moving upwind of any uncontrolled release. The
wind may shift. On a calm day the ammonia cloud expands
in all directions.
▲ Notify:
Summon any aid required. Notify local authorities of any
uncontrolled release. Protect the public. Protect livestock if
that can be done without further exposure.
▲ Stay in Contact:
Be available to responders with whatever information they
require. Do not attempt to correct the accident problem
yourself. Standard field PPE
a
safety equipment is suitable
only for normal operations and escape. Field PPE
is not
safe for emergency response.
