SECTION 4: First aid measures
Description of first aid measures
First-aid measures after inhalation : If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult,
give oxygen. Immediately call a POISON CENTER or doctor/physician.
First-aid measures after skin contact : IF ON SKIN (or hair): Remove/Take off immediately all contaminated clothing. Rinse skin with
water/shower. Wash contaminated clothing before reuse. Immediately call a POISON CENTER
or doctor/physician.
First-aid measures after eye contact : In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. If easy to
do, remove contact lenses, if worn. Get medical attention immediately.
First-aid measures after ingestion : If swallowed, do NOT induce vomiting unless directed to do so by medical personnel. Never
give anything by mouth to an unconscious person. Immediately call a POISON CENTER or
doctor/physician.
Most important symptoms and effects, both acute and delayed
Symptoms/injuries after inhalation : Harmful if inhaled. May cause respiratory tract irritation.
Symptoms/injuries after skin contact : Harmful in contact with skin. Causes severe burns. Symptoms may include redness, pain,
blisters. Repeated exposure to this material can result in absorption through skin causing
significant health hazard. May cause an allergic skin reaction.
Symptoms/injuries 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/injuries after ingestion : Harmful if swallowed. This product may be aspirated into the lungs and cause chemical pneumonitis.
May be fatal if swallowed and enters airways. May cause burns or irritation of the linings of the
mouth, throat, and gastrointestinal tract. May cause stomach distress, nausea or vomiting.
Indication of any immediate medical attention and special treatment needed
Symptoms may not appear immediately. In case of accident or if you feel unwell, seek medical advice immediately (show the label or SDS 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, nitrogen oxides,
amines, ammonia, nitric acid, cyanides, aldehydes, nitrosamines. 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 reaction known under conditions of normal 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 from entering into soil, ditches, sewers, waterways and/or groundwater. See Section 12, Ecological Information.
Methods and material for containment and cleaning up
For containment : Stop leak if safe to do so. Contain and/or absorb spill with inert material (e.g. sand, vermiculite),
then place in a suitable container. Do not flush to sewer or allow to enter waterways. Use
appropriate Personal Protective Equipment (PPE). Do not absorb in sawdust, paper, cloth or
other combustible absorbents.
Methods for cleaning up : Scoop up material and place in a disposal container. Provide ventilation.
Reference to other sections
See section 8 for further information on protective clothing and equipment and section 13 for advice on waste disposal.
SECTION 7: Handling and storage
Precautions for safe handling
Precautions for safe handling : 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. Use only outdoors or in a well-
ventilated area. Do not eat, drink or smoke when using this product. 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 : Launder contaminated clothing before reuse. Wash hands before eating, drinking, or smoking.
Contaminated work clothing should not be allowed out of the workplace.
Conditions for safe storage, including any incompatibilities
Storage conditions : Keep out of the reach of children. Keep container tightly closed. Store in a dry, cool and well-
ventilated place. Protect from moisture. Storage temperature : 40 F (4 C) – 90 F (32 C).
