TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Highly flammable.
NO open flames, NO sparks, and NO smoking.
Foam, powder, carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive.
Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
AVOID ALL CONTACT!

Inhalation Cough. Shortness of breath. Sore throat.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
Skin Redness.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes Redness. Pain.
Safety goggles, or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion Nausea. Vomiting. Abdominal pain.
Do not eat, drink, or smoke during work.
Rinse mouth. Give plenty of water to drink. Refer for medical attention.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer. Remove all ignition sources. (Extra personal protection: filter respirator for organic gases and vapours.) Chemical protection suit.

METHYL METHACRYLATE ICSC: 0300
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
The vapour mixes well with air, explosive mixtures are easily formed. Vapours are not inhibited, they may polymerize and block the vents.

CHEMICAL DANGERS:
The substance may polymerize due to warming or due to heating, under the influence of light, polymerization catalysts and strong oxidants with fire or explosion hazard. Reacts with strong acids strong bases.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 50 ppm as TWA; 100 ppm as STEL; SEN; A4; (ACGIH 2003).
MAK: 50 ppm, 210 mg/m; Sh; Peak limitation category: I(2); Pregnancy risk group: C; (DFG 2003).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

INHALATION RISK:
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes, the skin and the respiratory tract.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the peripheral nervous system.
PHYSICAL PROPERTIES
Boiling point: 100.5C
Melting point: -48C
Relative density (water = 1): 0.94
Solubility in water, g/100 ml at 20C: 1.6
Vapour pressure, kPa at 20C: 3.9
Relative vapour density (air = 1): 3.5
Relative density of the vapour/air-mixture at 20C (air = 1): 1.09
Flash point: 10C o.c.
Auto-ignition temperature: 421C
Explosive limits, vol% in air: 1.7-12.5
Octanol/water partition coefficient as log Pow: 1.38
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms.
NOTES
Usually contains hydroquinone, hydroquinone methyl ether and dimethyl t-butylphenol as inhibitors of polymerization. An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert. Do NOT take working clothes home.
