arnings. Read and understand all instruction manuals before operating equipment.
FLUID
INJECTION HAZARD
General
Safety
This
equipment generates very high fluid pressure. Spray from
the
gun, leaks or ruptured components can inject fluid through
your
skin and into
your body
, and cause extremely injury
, includ
-
ing
the need for amputation. Also, fluid injected or splashed into
the
eyes or on the skin can cause damage.
Never
point the spray gun at any one or at any part of the body
.
Never put your hand or fingers over the spray tip. Never try to
“blow back” paint; this is not an air spray system.
Always
have the tip guard in place on the spray gun when spray
-
ing.
Always follow the Pressure Relief Procedure, below, before
cleaning or removing the spray tip or servicing any system
equipment.
NEVER
try to stop or deflect leaks with your hand or body
.
Be
sure equipment safety devices are operating properly before
each
use.
Medical
Alert––Airless Spray W
ounds
If any fluid appears to penetrate your skin, get emergency
medical care at once. Do not treat as
a simple cut
. T
ell the
doctor exactly what fluid was injected.
Note
to Physician
:
Injection in the skin is a traumatic injury
.
It
is important to treat the injury surgically as soon as possible.
Do not delay treatment to research toxicity. Toxicity is a
concern with some exotic coatings injected directly into the
blood stream. Consultation with a plastic surgeon or re-
constructive
hand surgeon may be advisable
.
Spray
