PHYSICAL STATE; APPEARANCE:
LIQUID

PHYSICAL DANGERS:
Vapours are uninhibited and may polymerize in vents and flame arresters causing blockage.

CHEMICAL DANGERS:
The substance may polymerize.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour.

INHALATION RISK:
No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C.

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

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization. See Notes.

ENVIRONMENTAL
DATA

See Notes.

N O T E S

Explosive limits are unknown in literature, although the substance is combustible and has a flash point < 55°C. Health effects of exposure to the substance have not been investigated adequately. Environmental effects from the substance have not been investigated but the n-hexyl acrylate ICSC1288 was found toxic to aquatic organisms. An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
NFPA Code: H2; F2; R0;
