SECTION 4: First aid measures
Description of first aid measures
First-aid measures after inhalation : If inhaled: Remove person to fresh air and keep comfortable for breathing. Immediately call a
POISON CENTER/doctor.
First-aid measures after skin contact : If on skin (or hair): Take off immediately all contaminated clothing. Rinse skin with
water/shower. Wash contaminated clothing before reuse. Immediately call a POISON
CENTER/doctor.
First-aid measures after eye contact : IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present
and easy to do. Continue rinsing. Immediately call a POISON CENTER/doctor.
First-aid measures after ingestion : IF SWALLOWED: rinse mouth. Do NOT induce vomiting. Never give anything by mouth to an
unconscious person. Immediately call a POISON CENTER/doctor.
Most important symptoms and effects, both acute and delayed
Symptoms/effects after inhalation : Causes burns to the respiratory system.
Symptoms/effects after skin contact : Causes severe skin burns. Symptoms may include redness, pain, blisters. May cause an
allergic skin reaction.
Symptoms/effects after eye contact : Causes serious eye damage. Symptoms may include discomfort or pain, excess blinking and
tear production, with marked redness and swelling of the conjunctiva. May cause burns.
Symptoms/effects after ingestion : Harmful if swallowed. May cause gastrointestinal irritation, nausea, vomiting and diarrhea. May
cause burns or irritation of the linings of the mouth, throat, and gastrointestinal tract.
Indication of any immediate medical attention and special treatment needed
Symptoms may be delayed. In case of accident or if you feel unwell, seek medical advice immediately (show the label where possible).
SECTION 5: Firefighting measures
Extinguishing media
Suitable extinguishing media : Foam. Carbon dioxide. Dry chemical.
Unsuitable extinguishing media : Do not use a heavy water stream.
Special hazards arising from the substance or mixture
Fire hazard : Products of combustion may include, and are not limited to: oxides of carbon. Oxides of
nitrogen. Amines. Ammonia. Nitric acid. Irritating fumes. When mixed with sawdust, wood
chips, or other cellulosic material, spontaneous combustion can occur under certain conditions.
Heat is generated as the air oxidizes the amine. If the heat is not dissipated quickly enough, it
can ignite the sawdust.
Reactivity : No dangerous reactions known under normal conditions of use.
Advice for firefighters
Protection during firefighting : Keep upwind of fire. Wear full fire fighting turn-out gear (full Bunker gear) and respiratory
protection (SCBA).

SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
General measures : Use personal protection recommended in Section 8. Isolate the hazard area and deny entry to
unnecessary and unprotected personnel.
For non-emergency personnel
No additional information available
For emergency responders
No additional information available
Environmental precautions
Prevent entry to sewers and public waters. Notify authorities if product enters sewers or public waters.
Methods and material for containment and cleaning up
For containment : Absorb and/or contain spill with inert material (sand, vermiculite or other appropriate material),
then place in suitable container. Do not flush into surface water or sewer system. Wear
recommended personal protective equipment. Do not use sawdust or other combustible
material to absorb spilled material.
Methods for cleaning up : Sweep or shovel spills into appropriate container for disposal. Provide ventilation.
Reference to other sections
For further information refer to section 8: “Exposure controls/personal protection”.
SECTION 7: Handling and storage
Precautions for safe handling
Precautions for safe handling : DO NOT spray apply or heat this product. Obtain special instructions before use. Do not handle
until all safety precautions have been read and understood. Do not get in eyes, on skin, or on
clothing. Do not breathe dust/fume/gas/mist/vapours/spray. Do not swallow. Handle and open
container with care. Do not eat, drink or smoke when using this product. Ensure adequate
ventilation. When mixed with epoxy resin this product causes an exothermic reaction, which in
large masses, can produce enough heat to damage or ignite surrounding materials and emit
fumes and vapors that vary widely in composition and toxicity.
Hygiene measures : Wash contaminated clothing before reuse. Always wash hands after handling the product.
Conditions for safe storage, including any incompatibilities
Storage conditions : Keep out of the reach of children. Keep container tightly closed. Store in dry, cool, well-
ventilated area. Store locked up.
Storage temperature : 40 – 90 F / 4 – 32 C
