PHYSICAL STATE; APPEARANCE:
COLOURLESS CRYSTALS OR CRYSTALLINE POWDER

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating above 45°C.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK not established.


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by ingestion.

INHALATION RISK:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especialy if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the liver and kidney , resulting in liver impairment and kidney impairment only in case of large amount ingested. The effects may be delayed. Medical observation is indicated. See Notes.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the kidneys and liver , resulting in impaired functions. May cause genetic damage in humans.
PHYSICAL
PROPERTIES
Boiling point: >500°C
Melting point: 169-170°C
Solubility in water, g/100 ml at 20°C: 1.4
Octanol/water partition coefficient as log Pow: 0.49
ENVIRONMENTAL
DATA
The substance is toxic to aquatic organisms.
N O T E S
Temperature of decomposition unknown in literature. Health effects of exposure by inhalation to the substance have not been investigated. Use of alcoholic beverages enhances the harmful effect. The symptoms of acute intoxications do not become manifest until some 24-48 h to 3-4 days after ingestion of toxic doses. APAP, Panadol, Tempra, Tylenol are trade names.
