PHYSICAL STATE; APPEARANCE:
COLOURLESS CRYSTALS , WITH CHARACTERISTIC ODOUR. TURNS DARK ON EXPOSURE TO AIR AND LIGHT .

PHYSICAL DANGERS:


CHEMICAL DANGERS:
Reacts violently with strong oxidants . The solution in water is a weak acid.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 5 ppm as TWA (skin) (ACGIH 2008).
MAK: skin absorption (H);
Carcinogen category: 3A; BAT issued;
(DFG 2008).
tions for the allocation into the category 4 or 5 would be fulfilled but there is not enough information to derive a MAK-value.
OSHA PEL: TWA 5 ppm (22 mg/m3) skin
NIOSH REL: TWA 2.3 ppm (10 mg/m3)
NIOSH IDLH: 250 ppm See: cresol


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion. Serious local effects by all routes of exposure.

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 corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. Inhalation may cause lung oedema, but only after initial corrosive effects on eyes and/or airways have become manifest. The substance may cause effects on the central nervous system , resulting in lowering of consciousness. The substance may cause effects on the blood , resulting in destruction of blood cells. Exposure far above the OEL may result in death . Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the nervous system , resulting in impaired functions. The substance may have effects on the blood , resulting in anaemia.
