Inhalation:Remove victim to fresh air and keep at rest in a position comfortable for breathing.
Call a POISON CENTER or doctor/physician if you feel unwell.
Skin contact:Remove/Take off immediately all contaminated clothing. Gently wash with plenty of
soap and water. Call a POISON CENTER or doctor/physician.
Eye contact:Rinse cautiously with water for several minutes. Remove contact lenses, if present
and easy to do. Continue rinsing. If eye irritation persists: Get medical
advice/attention.
Call a POISON CENTER or doctor/physician if you feel unwell. Rinse mouth.
Ingestion:
Protection of first-aiders:A rescuer should wear personal protective equipment, such as rubber gloves and air-
tight goggles.
Section5. FIRE-FIGHTING MEASURES
Dry chemical, foam, carbon dioxide.
Suitable extinguishing
media:
Unsuitable extinguishing Water (It may scatter and spread fire.)
media:
Precautions for firefighters: Fire-extinguishing work is done from the windward and the suitable fire-extinguishing
method according to the surrounding situation is used. Uninvolved persons should
evacuate to a safe place. In case of fire in the surroundings: Keep containers cool by
spraying with water. Eliminate all ignition sources if safe to do so.
When extinguishing fire, be sure to wear personal protective equipment.
Special protective
equipment for firefighters:
Section6. ACCIDENTAL RELEASE MEASURES
Personal precautions,Use extra personal protective equipment (self-contained breathing apparatus). Keep
protective equipment and people away from and upwind of spill/leak. Ensure adequate ventilation. Entry to non-
emergency procedures: involved personnel should be controlled around the leakage area by roping off, etc.
Environmental precautions: Prevent product from entering drains.
Methods and materials for Absorb spilled material in dry sand or inert absorbent before recovering it into an
containment and cleaning airtight container. In case of large amount of spillage, contain a spill by bunding.
up: Adhered or collected material should be promptly disposed of, in accordance with
appropriate laws and regulations.
Prevention of secondary Remove all sources of ignition. Fire-extinguishing devices should be prepared in
case of a fire. Use spark-proof tools and explosion-proof equipment.
hazards:
Section7. HANDLING AND STORAGE
Precautions for safe handling
Handling is performed in a well ventilated place. Wear suitable protective equipment.
Technical measures:
Prevent generation of vapour or mist. Keep away from heat/sparks/open flame/hot
surfaces. -No smoking. Take measures to prevent the build up of electrostatic
charge. Use explosion-proof equipment. Wash hands and face thoroughly after
handling.
2-Ethylcrotonaldehyde
Section7. HANDLING AND STORAGE
