Section4. FIRST AID MEASURES
Inhalation:Remove victim to fresh air and keep at rest in a position comfortable for breathing.
Get medical advice/attention if you feel unwell.
Skin contact:Remove/Take off immediately all contaminated clothing. Rinse skin with
water/shower. If skin irritation or rash occurs: Get medical advice/attention.
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.
Ingestion:Get medical advice/attention if you feel unwell. Rinse mouth.
A rescuer should wear personal protective equipment, such as rubber gloves and air-
Protection of first-aiders:
tight goggles.

from the chemical:Container may explode when heated. Combat fire from a sheltered position.
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.
Special protectiveWhen extinguishing fire, be sure to wear personal protective equipment.

Section6. ACCIDENTAL RELEASE MEASURES
Personal precautions,Use personal protective equipment. Keep people away from and upwind of spill/leak.
protective equipment and Ensure adequate ventilation. Entry to non-involved personnel should be controlled
emergency procedures: 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 a
containment and cleaning covered 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
hazards:case of a fire. Use spark-proof tools and explosion-proof equipment.

Section7. HANDLING AND STORAGE
Precautions for safe handling
Technical measures:Handling is performed in a well ventilated place. Wear suitable protective equipment.
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.
Use a closed system if possible. Use a ventilation, local exhaust if vapour or aerosol
will be generated.
Advice on safe handling: Avoid contact with skin, eyes and clothing.
Conditions for safe storage, including any
incompatibilities
Storage conditions:Keep container tightly closed. Store in a cool, dark and well-ventilated place.
Store away from incompatible materials such as oxidizing agents.
Packaging material:Comply with laws.
