m-NITROTOLUENE ICSC: 1411
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
YELLOW LIQUID OR YELLOW CRYSTALS, WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic gases, including carbon monoxide and nitrogen oxides. Reacts with strong oxidants and sulfuric acid, causing fire and explosion hazard. Attacks plastic, rubber and coatings.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 2 ppm as TWA; (skin); BEI issued; (ACGIH 2004).
MAK: 5 ppm 28 mg/m; Peak limitation category: II(2); skin absorption (H); (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion.

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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is mildly irritating to the eyes and the skin. The substance may cause effects on the blood, resulting in the formation of methaemoglobin. Medical observation is indicated. The effects may be delayed.

PHYSICAL PROPERTIES
Boiling point: 231.9C
Melting point: 16.1C
Density: 1.16 g/cm
Solubility in water, g/100 ml at 20C: 0.05
Relative vapour density (air = 1): 4.73
Flash point: 106C c.c.
Explosive limits, vol% in air: 1.6-?
Octanol/water partition coefficient as log Pow: 2.45
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms.
NOTES
Depending on the degree of exposure, periodic medical examination is suggested. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Environmental effects from the substance have not been investigated adequately.
Card has been partly updated in April 2005. See section Occupational Exposure Limits.
