TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Highly flammable.
NO open flames, NO sparks, and NO smoking.
Powder, AFFF, foam, 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. Pain
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
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 Abdominal pain Diarrhoea. Nausea. Vomiting.
Do not eat, drink, or smoke during work.
Rinse mouth. Give plenty of water to drink. Do NOT induce vomiting. Refer for medical attention.
SPILLAGE DISPOSAL PACKAGING & LABELLING

METHYL ACRYLATE ICSC: 0625
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID, WITH PUNGENT ODOUR.

PHYSICAL DANGERS:
The vapour is heavier than air and may travel along the ground; distant ignition possible. The vapours are uninhibited and may polymerize, blocking vents.

CHEMICAL DANGERS:
The substance may polymerize spontaneously due to warming, under the influence of light and on contact with peroxides. Reacts violently with strong acids, strong bases, strong oxidants causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 2 ppm as TWA; (skin); A4; (ACGIH 2003).
MAK: 5 ppm, 18 mg/m; Sh; Peak limitation category: I(1); Pregnancy risk group: IIc; (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 very quickly on evaporation of this substance at 20C.

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

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization.
PHYSICAL PROPERTIES
Boiling point: 80.5C
Melting point: -76.5C
Relative density (water = 1): 0.95
Solubility in water, g/100 ml at 20C: 6
Vapour pressure, kPa at 20C: 9.1
Relative vapour density (air = 1): 3.0
Relative density of the vapour/air-mixture at 20C (air = 1): 1.18
Flash point: -2.8C c.c.
Auto-ignition temperature: 468C
Explosive limits, vol% in air: 2.8-25
Octanol/water partition coefficient as log Pow: 0.8
ENVIRONMENTAL DATA
The substance is toxic to aquatic organisms.
NOTES
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert. The odour warning when the exposure limit value is exceeded is insufficient. Do NOT take working clothes home.
