Teratogenicity/Reproductive toxicity: No known significant effects or critical hazards.
Medical conditions aggravated by overexposure: Repeated skin exposure can produce local skin
destruction or dermatitis. Repeated or prolonged exposure to the substance can produce lung damage.
Repeated or prolonged contact with spray or mist may produce chronic eye irritation and severe skin
irritation. Repeated or prolonged exposure to the substance can produce target organs damage.

4. FIRST AID MEASURES
Eye contact: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the
upper and lower eyelids. Check for and remove any contact lenses. Get medical attention.
Skin contact: Get medical attention immediately. Flush contaminated skin with plenty of water. Continue to
rinse for at least 10 minutes. Remove contaminated clothing and shoes.
Wash contaminated clothing thoroughly with water before removing or wear gloves.
Wash clothing before reuse. Clean shoes thoroughly before reuse.
Inhalation: Get medical attention immediately. Move exposed person to fresh air. If it is suspected that
fumes are still present, the rescuer should wear an appropriate mask or selfcontained breathing apparatus.
Keep person warm and at rest. If not breathing, if breathing is irregular or if respiratory arrest occurs, provide
artificial respiration or oxygen by trained personnel. It may be dangerous to the person providing aid to give
mouthto- mouth resuscitation. If unconscious, place in recovery position and get medical attention
immediately. Maintain an open airway. Loosen tight clothing such as a collar, tie, belt or waistband.
Ingestion: Get medical attention immediately. Wash out mouth with water. Remove dentures if any. Move
exposed person to fresh air. Keep person warm and at rest. If material has been swallowed and the
exposed person is conscious, give small quantities of water to drink. Stop if the exposed person feels sick
as vomiting may be dangerous. Do not induce vomiting unless directed to do so by medical personnel. If
vomiting occurs, the head should be kept low so that vomit does not enter the lungs. Never give anything by
mouth to an unconscious person. If unconscious, place in recovery position and get medical attention
immediately. Maintain an open airway. Loosen tight clothing such as a collar, tie, belt or waistband.
Protection of first-aiders: No action shall be taken involving any personal risk or without suitable training. If
it is suspected that fumes are still present, the rescuer should wear an appropriate mask or self-contained
breathing apparatus. It may be dangerous to the person providing aid to give mouth-to-mouth resuscitation.

5. FIRE FIGHTING MEASURES
Flammability of the product: Extremely flammable liquid and vapor. Vapor may cause flash fire. Vapors may
accumulate in low or confined areas or travel a considerable distance to a source of ignition and flash back.
Runoff to sewer may create fire or explosion hazard.
Products of combustion: These products are carbon oxides (CO, CO 2).
Extinguishing media:

	Suitable: Use dry chemical, CO2, water spray (fog) or foam.
	Not suitable: Do not use water jet.

Special exposure hazards: Not available.
Special remarks on firehazards: Vapor may travel a considerable distance to source of ignition and flash
back.
Special protective equipment for fire-fighters: Fire-fighters should wear appropriate protective equipment
and self-contained breathing apparatus (SCBA) with a full face-piece operated in positive pressure mode.

7. HANDLING AND STORAGE
Information for safe handling: Do not ingest. Avoid contact with eyes, skin and clothing. Keep container
closed. Use only with adequate ventilation. Avoid breathing vapor or mist. Keep away from heat, sparks and
flame. To avoid fire or explosion, dissipate static electricity during transfer by grounding and bonding
containers and equipment before transferring material. Use explosion-proof electrical (ventilating, lighting
and material handling) equipment. Wash thoroughly after handling.
Information about safe storage: Store in a segregated and approved area. Keep container in a cool, well-
ventilated area. Keep container tightly closed and sealed until ready for use. Avoid all possible sources of
ignition (spark or flame).

8. EXPOSURE CONTROLS AND PERSONAL PROTECTION
Additional information about design of technical systems: Properly operating chemical fume hood
designed for hazardous chemicals and having an average face velocity of at least 100 feet per minute.
General protective and hygienic measures: Wash hands, forearms and face thoroughly after handling
chemical products, before eating, smoking and using the lavatory and at the end of the working period.
Appropriate techniques should be used to remove potentially contaminated clothing. Wash contaminated
clothing before reusing. Ensure that eyewash stations and safety showers are close to the workstation
location.
Breathing equipment: Use suitable respirator when high concentrations are present.
Protection of hands: Impervious gloves
Eye protection: splash goggles
Body protection: Protective work clothing (i.e. lab coat).
