Toluene
Properties
of toluene is described
below
PHYSICAL
STATE; APPEARANCE:
COLOURLESS LIQUID ,
WITH CHARACTERISTIC ODOUR.
PHYSICAL DANGERS:
The vapour mixes well with air, explosive mixtures are formed
easily. As a result of flow, agitation, etc., electrostatic charges can
be generated.
CHEMICAL DANGERS:
Reacts violently with strong oxidants causing fire and explosion
hazard.
OCCUPATIONAL EXPOSURE LIMITS:
TLV: 50 ppm as TWA; (skin); A4; BEI issued; (ACGIH 2004).
MAC: 50 ppm, 190 mg/m³; H;
Peak limitation category: II(4); Pregnancy risk group: C;
(DFG 2004).
OSHA PEL: TWA 200 ppm C 300 ppm 500 ppm (10-minute maximum peak)
NIOSH REL: TWA 100 ppm (375 mg/m3) ST 150 ppm (560 mg/m3)
NIOSH IDLH: 500 ppm
ROUTES
OF EXPOSURE:
The substance can be
absorbed into the body by inhalation, through the skin and by ingestion.
INHALATION RISK:
A harmful contamination of the air can be reached rather quickly on
evaporation of this substance at 20°C.
EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes and the respiratory tract .
The substance may cause effects on the central nervous system . If this
liquid is swallowed, aspiration into the lungs may result in chemical
pneumonitis. Exposure at high levels may result in cardiac
dysrhythmiaandunconsciousness.
EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin. The substance may have effects on the
central nervous system . Exposure to the substance may enhance hearing
damage caused by exposure to noise. Animal tests show that this
substance possibly causes toxicity to human reproduction or development.
