INFORMATION FOR FIRST AID AND CASUALTY ON TREATMENT FOR ADHESION OF
HUMAN SKIN TO ITSELF IF CAUSED BY CYANOACRYLATE ADHESIVES

Cyanoacrylate adhesive is a very fast setting and strong adhesive. It
bonds human tissue including skin in seconds. Experience has shown
that accidents due to cyanoacrylates are handled best by passive,
nonsurgical first aid. Treatment of specific types of accidents are
given below.

SKIN CONTACT
Remove excess adhesive. Soak in warm, soapy water. The adhesive will
come loose from the skin in several hours. Cured adhesive does not
present a health hazard even when bonded to the skin.

Avoid contact with clothes, fabrics, rags, or tissue. Contact with
these materials may cause polymerization. The polymerization of large
amounts of adhesive will generate heat causing smoke, skin burns,
and strong, irritating vapors. Wear nitrile or polyethylene gloves and
apron when handling large amounts of adhesive.

SKIN ADHESION
First immerse the bonded surfaces in warm, soapy water. Peel or roll
the surfaces apart with the aid of a blunt edge, e.g. a spatula or a
teaspoon handle; then remove adhesive from the skin with soap and
water. Do not try to pull surfaces apart with a direct opposing
action.

EYELID TO EYELID OR EYEBALL ADHESION
In the event that eyelids are stuck together or bonded to the eyeball,
wash thoroughly with warm water and apply a gauze patch. The eye will
open without further action, typically in 1-4 days. There will be no
residual damage. Do not try to open the eyes by manipulation.

ADHESIVE ON THE EYEBALL
Cyanoacrylate introduced into the eyes will attach itself to the
eye protein and will disassociate from it over intermittent periods,
generally covering several hours. This will cause periods of weeping
until clearance is achieved. During the period of contamination,
double vision may be experienced together with a lachrymatory effect,
and it is important to understand the cause and realize that
disassociation will normally occur within a matter of hours, even with
gross contamination.

MOUTH
If lips are accidentally stuck together, apply lots of warm water to
the lips and encourage maximum wetting and pressure from saliva inside
the mouth. Peel or roll lips apart. Do not try to pull the lips

with direct opposing action.

It is almost impossible to swallow cyanoacrylate. The adhesive
solidifies and adheres in the mouth. Saliva will lift the adhesive in
one half to two days. In case a lump forms in the mouth, position the
patient to prevent ingestion of the lump when it detaches.

BURNS
Cyanoacrylates give off heat on solidification. In rare cases a large
drop will increase in temperature enough to cause a burn.
Burns should be treated normally after the lump of cyanoacrylate is
released from the tissue as described above.

SURGERY
It should never be necessary to use such a drastic method to separate
accidentally bonded skin.
