AC 43.13-1B
1-18. GENERAL. The possibility of an in-
jury is an important consideration when
working with wooden aircraft structures. The
tools and machines used to shape wooden
members can be very dangerous. In addition,
there are potential health hazards in working
with adhesives and finishes. The mechanic
should follow manufacturer’s instructions
wherever applicable to prevent injury. Federal
law mandates that individual chemical manu-
facturers are to provide Material Safety Data
Sheets (MSDS) with health hazard data to all
consumers. First aid information and handling
precautions must also be identified. Most of
the products used in wooden aircraft construc-
tion are flammable. Some, such as dope and
paint, may be highly flammable.
1-19. SANDING IN AREAS OF EXIST-
ING BOND JOINTS AND FINISHES.
Some adhesives used in wooden aircraft con-
struction contain biocides. A commonsense
precaution when machining or sanding exist-
ing structure is to wear a respirator to avoid
inhaling dust products. To lower potential fire
hazards avoid using electric sanders around
dope, paints, and adhesives.
1-20. HANDLING OF ADHESIVES AND
FINISHES. Most adhesives and finish prod-
ucts present at least some toxic potential to us-
ers. Injury may occur from skin or eye contact,
inhalation, or accidental ingestion. Users
should be aware of the manufacturer’s instruc-
tions and MSDS.
a. Appropriate skin, eye, ear, and respi-
ratory protection should be worn whenever in-
dicated.
b. Shop cleanliness is essential for health
and fire safety.
c. Shop personnel should maintain
awareness of others in the work area to assure
that bystanders are not injured.
d. Proper shop ventilation is essential to
disperse fumes emitted from adhesives such as
resorcinol and epoxy.
