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.
• Tell the doctor that you suspect an injection injury.
• Show them this card
• Tell them what kind of material you were spraying
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.
