Emergency medical information and treatment
The use of high-pressure equipment exposes the operator and other people in the area to high-pressure water. 
Potential harms include eye injuries, lacerations, infections, and amputations. Do not put ice or heat on a waterjet 
injury. Support injured limbs and extremities above heart level if possible.
A high-pressure injection injury is a surgical emergency. Seek immediate medical treatment for all high-pressure 
waterjet injuries. Delayed treatment can cause serious injuries or death.
Waterjet operators should carry a waterproof emergency medical tag or card that describes the nature of 
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.
Seek immediate medical treatment for 
all high-pressure waterjet injuries.
Delayed treatment can cause serious 
injuries or death.
The person carrying this card has been 
exposed to a waterjet of up 
to 4,137 bar (60,000 psi) and a velocity 
of 609 m/s (2,000 feet/second). The 
waterjet can contain abrasive 
materials.
Skin can appear intact or show a minor 
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.
Administer broad-spectrum, intravenous 
antibiotics for Gram-negative and 
Gram-positive organisms.
X-ray is the imaging of choice.
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.
