Personal Safety
Obtain and read Safety Data Sheets (SDS) for
S
all materials used. Follow the manufacturer's
instructions for safe handling and use of
materials, and use recommended personal
protection devices.
Make sure the spray area is adequately
S
ventilated.
To prevent injury, be aware of less-obvious
S
dangers in the workplace that often cannot be
completely eliminated, such as hot surfaces,
sharp edges, energized electrical circuits, and
moving parts that cannot be enclosed or
otherwise guarded for practical reasons.

High-Pressure Fluids

High-pressure fluids, unless they are safely
contained, are extremely hazardous. Always
relieve fluid pressure before adjusting or servicing
high pressure equipment. A jet of high-pressure
fluid can cut like a knife and cause serious bodily
injury, amputation, or death. Fluids penetrating the
skin can also cause toxic poisoning.
If you suffer a fluid injection injury, seek medical
care immediately. If possible, provide a copy of the
SDS for the injected fluid to the health care
provider.
The National Spray Equipment Manufacturers
Association has created a wallet card that you
should carry when you are operating high-pressure
spray equipment. These cards are supplied with
your equipment. The following is the text of this
card:
WARNING: Any injury caused by high
pressure liquid can be serious. If you are
injured or even suspect an injury:
Go to an emergency room immediately.

MEDICAL ALERT—AIRLESS SPRAY WOUNDS:
NOTE TO PHYSICIAN
Injection in the skin is a serious 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 bloodstream.
Consultation with a plastic surgeon or a
reconstructive hand surgeon may be advisable.
The seriousness of the wound depends on where
the injury is on the body, whether the substance hit
something on its way in and deflected causing
more damage, and many other variables including
skin microflora residing in the paint or gun which
are blasted into the wound. If the injected paint
contains acrylic latex and titanium dioxide that
damage the tissue's resistance to infection,
bacterial growth will flourish. The treatment that
doctors recommend for an injection injury to the
hand includes immediate decompression of the
closed vascular compartments of the hand to
release the underlying tissue distended by the
injected paint, judicious wound debridement, and
immediate antibiotic treatment.

Fire Safety

To avoid a fire or explosion, follow these
instructions.
Ground all conductive equipment. Use only
S
grounded air and fluid hoses. Check equipment
and workpiece grounding devices regularly.
Resistance to ground must not exceed one
megohm.
Shut down all equipment immediately if you
S
notice static sparking or arcing. Do not restart
the equipment until the cause has been
identified and corrected.
Do not smoke, weld, grind, or use open flames
S
where flammable materials are being used or
stored.
Do not heat materials to temperatures above
S
those recommended by the manufacturer.
Make sure heat monitoring and limiting devices
are working properly.
