	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Combustible. Above 97°C explosive vapour/air mixtures may be formed.	NO open flames. Above 97°C use a closed system and ventilation.	Use water spray, dry powder, alcohol-resistant foam. In case of fire: keep drums, etc., cool by spraying with water.

PREVENT GENERATION OF MISTS!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Sore throat.	Use ventilation (not if powder), local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	Redness.	Protective gloves. Protective clothing.	First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer for medical attention .
Eyes	Redness.	Wear safety spectacles 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	Sore throat. Aspiration hazard!	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer immediately for medical attention.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: chemical protection suit and filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Collect leaking liquid in covered containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.	According to UN GHS Criteria May be harmful if swallowed Causes skin and eye irritation May cause allergic skin reaction May be harmful if swallowed and enters airways Transportation UN Classification
STORAGE
Store only if stabilized. Keep in the dark. Cool. Ventilation along the floor.

2-HYDROXYETHYL METHACRYLATE

ICSC: 1724

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS LIQUID. Physical dangers Chemical dangers The substance will polymerize due to heating, on contact with peroxides, and under the influence of light. Heating may cause violent combustion or explosion. This produces acrid smoke. The substance may spontaneously polymerize if it is not stabilized.	Formula: C₆H₁₀O₃ Molecular mass: 130.1 Boiling point: 250°C (calculated) See Notes. Melting point: <-60°C Density: 1.07 g/cm³ Solubility in water: miscible Vapour pressure, Pa at 25°C: 17 Relative vapour density (air = 1): 4.5 Flash point: 97°C c.c. Octanol/water partition coefficient as log Pow: 0.42 Viscosity: 8.4 mm²/s at 20°C

EXPOSURE & HEALTH EFFECTS
Routes of exposure Effects of short-term exposure The substance is irritating to the eyes, skin and respiratory tract. If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis.	Inhalation risk No indication can be given about the rate at which a harmful concentration of this substance in the air is reached. Effects of long-term or repeated exposure Repeated or prolonged contact may cause skin sensitization. See Notes.

EXPOSURE & HEALTH EFFECTS

Routes of exposure

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis.

Inhalation risk
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached.

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. See Notes.

OCCUPATIONAL EXPOSURE LIMITS
MAK sensitization of skin (SH)

ENVIRONMENT

NOTES
Boiling Point cannot be experimentally determined: at 1013 hPa polymerization occurs at elevated temperatures, other boiling point: 67 C at 4.6 hPa. Methacrylates are normally stabilized by addition of phenolic inhibitors during transport and storage. An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert. May cause cross sensitization towards other acrylates.
