CAS #: 137-05-3

EC Number: 205-275-2

	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Above 79°C explosive vapour/air mixtures may be formed.	NO open flames. Above 79°C use a closed system and ventilation.	Use foam, powder, carbon dioxide. NO water. In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water.

AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Headache. Sore throat.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	Dry skin. Redness. Pain.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention .
Eyes	Redness. Pain.	Wear face shield or eye protection in combination with breathing protection.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion		Do not eat, drink, or smoke during work.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: face shield and filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Ventilation. Remove all ignition sources. Do NOT wash away into sewer. Absorb liquid in sand or inert absorbent. Let solidify.	According to UN GHS Criteria Transportation UN Classification
STORAGE
Separated from incompatible materials. See Chemical Dangers. Well closed. Store only if stabilized.

METHYL 2-CYANOACRYLATE

ICSC: 1272

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS LIQUID. Physical dangers Chemical dangers The substance rapidly polymerizes , especially under the influence of moisture. Decomposes on heating and on burning. This produces toxic and irritating fumes and gases including nitrogen oxides.

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its vapour. Effects of short-term exposure The vapour is irritating to the eyes and respiratory tract. Inhalation of the vapour may cause asthmatic reactions. See Notes. Immediately glues (sticks to) biological tissues.	Inhalation risk A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C. Effects of long-term or repeated exposure Repeated or prolonged contact with skin may cause dermatitis.

OCCUPATIONAL EXPOSURE LIMITS
TLV: 0.2 ppm as TWA; 1 ppm as STEL; (DSEN); (RSEN). MAK: 9.2 mg/m³, 2 ppm; peak limitation category: I(1); pregnancy risk group: D

ENVIRONMENT

NOTES
Depending on the degree of exposure, periodic medical examination is suggested. The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Anyone who has shown symptoms of asthma due to this substance should avoid all further contact. An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
