EXPOSURE
PREVENT GENERATION OF MISTS! AVOID ALL CONTACT!

Inhalation Burning sensation. 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. Nausea. Vomiting. Diarrhoea.
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Give plenty of water to drink. Refer for medical attention.

BUTYL ACRYLATE ICSC: 0400
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
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 oxidants causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 2 ppm as TWA; A4 (not classifiable as a human carcinogen); SEN; (ACGIH 2002).
MAK: 2 ppm, 11 mg/m; Peak limitation category: I(2); sensitization of skin (Sh); Pregnancy risk group: D; (DFG 2003).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and through the skin.

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. If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization.
PHYSICAL PROPERTIES
Boiling point: 145-149C
Melting point: -64C
Relative density (water = 1): 0.90
Solubility in water, g/100 ml: 0.14
Vapour pressure, kPa at 20C: 0.43
Relative vapour density (air = 1): 4.42
Relative density of the vapour/air-mixture at 20C (air = 1): 1.01
Flash point: 36C c.c.
Auto-ignition temperature: 267C
Explosive limits, vol% in air: 1.3-9.9
Octanol/water partition coefficient as log Pow: 2.38
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. Hydroquinone and hydroquinone ethyl ether are the commonly used stabilizers. Do NOT take working clothes home.
