Emergency medical information and treatment
High-pressure equipment puts the operator and other personnel in the area at risk of contact with high-pressure
water. Possible injuries could include eye damage, lacerations, infections, and amputations. Do not put ice or heat
on a waterjet injury. Use a support to keep injured limbs and extremities above heart level, if possible.
Waterjet operators should have a waterproof emergency medical tag or card that describes high-pressure
waterjet injuries and the recommended treatment. Show the tag or card to emergency responders and medical
professionals.
This card can be copied, cut out, laminated, and folded.
A high-pressure injection injury is a
surgical emergency.
Get medical treatment immediately for
all high-pressure waterjet injuries.
The person with this card has been
exposed to a waterjet of up
to 4,140 bar (60,000 psi) and a velocity
of 609 m/s (2,000 feet/second). The
waterjet can contain abrasive
materials.
Skin can appear to be not damaged or
show a small pinhole-sized puncture
wound. The injured area can become
swollen, painful, and pale over the next 4
to 6 hours. Tissue becomes ischemic and
necrotic within 12 hours.
Consult a surgical specialist immediately
for decompression, removal of foreign
materials, and debridement.
Give broad-spectrum, intravenous
antibiotics for Gram-negative and
Gram-positive organisms.
X-ray is the preferred imaging method.
Acute compartment syndrome is possible.
Leave the wound open.
Do not use solvents other than isotonic
sodium chloride solution for irrigating the
wound.
Do not use digital or local nerve blocks.
Give analgesics by mouth or injection.
