Section 4 - First Aid
Measures
INHALATION:
Remove from exposure. If there is
difficulty in breathing. Seek medical attention
if symptoms persist.
SKIN
CONTACT:
Wash skin with soap and water
for at least 15 minutes while removing
contaminated clothing and shoes. Get
medical attention, if needed. Thoroughly clean and
dry
contaminated clothing and shoes
before reuse.

Section 5 - Fire Fighting Measures
SUITABLE EXTINGUISHING MEDLA:
Use water spray, foam, dry chemical or
carbon dioxide .
Keep containers and
surroundings cool with spray.
SPECIFIC
HAZARDS DURING FIRE FLGHTING:
This
product may give rise to hazardous
vapors in a fire. Vapors can travel a
considerable distance to a source of ignition and
result in
flashback.
SPECIAL
PROTECTIVE EQUIPMENT FOR FIRE-FIGHTERS:
Wear full protective clothing
and self-contained breathing apparatus.
FURTHER INFORMATION:
Pressure may build up in closed
containers with possible liberation
of
combustible vapors.
Section
6 - Accidental Release Measures
PERSONAL
PRECAUTIONS:
Wear suitable
protective clothing.
Wear respiratory
protection.
Eliminate all ignition
sources.
ENVIRONMENTAL PRECAUTIONS:
Prevent the material from entering
drains or water courses.
Do not
discharge directly to a water source.
Advise Authorities if spillage has
entered watercourse or sewer or has contaminated
soil or
vegetation .
METHODS
FOR CLEARING UP:
Cover with absorbent
or contain. Collect and dispose.
Section 7 - Handling and Storage
HANDLING
Use local exhaust
ventilation. Avoid contact with eyes, skin and
clothing. Keep container tightly
Closed. Further information on storage
conditions; Proprietary photo resist film contains
approximately 2-4% of
2.3.4-trihydroxybenzophenone (THBP).Which may
sublime during
soft-bake or hard-bake
processing. THBP has low acute toxicity
(LD50>5g/kg). Contact with
eyes. Skin
or mucous membranes cause irritation. To prevent
accumulation of THBP on
equipment
surfaces and ventilation ducts, preventative
maintenance program including regular
cleaning should be implemented. Wipe
surfaces using an appropriate cleaning solvent
when
possible. Provide adequate general
or local exhaust ventilation during the cleaning
process. In
situations where this is
not possible or where solvent or dust
concentrations become excessive.
Use an air purifying respirator with an
organic vapor/toxic particulate cartridge. When
cleaning
residual THBP, wear protective
gloves and adequate protective clothing to prevent
skin
contact. Practice good personal
hygiene to prevent accidental exposure. Clean all
protective
clothing and equipment
thoroughly after each use.
STORAGE
Storage conditions; Store in original
container. Keep away from heat and sources of
ignition,
