Properties of 1,1,1-trichloroehtane is described below
PHYSICAL STATE:
COLOURLESS LIQUID,
WITH CHARACTERISTIC ODOUR.
PHYSICAL DANGERS:
The vapor is heavier then air.
CHEMICAL DANGERS:
The substance decomposes on
heating or on burning producing toxic and corrosive fumes including
phosgene and hydrogen chloride. Reacts violently with aluminium,
manganese and their alloys, alkalis, strong oxidants, acetone and zinc.
Attacks natural rubber. Mixtures of 1,1,1-trichloroethane with potassium
or its alloys are shock sensitive. Reacts slowly with water releasing
corrosive hydrochloric acid.
OCCUPATION EXPOSURE LIMITS:
TLV: 350 ppm; 1910 mg/m3
(as TWA); 450 ppm; 2460 mg/m3 (as STEL) (ACGIH 1994-1995).
OSHA PEL: TWA 350 ppm (1900 mg/m3)
NIOSH REL: C 350 ppm (1900 mg/m3) 15-minute
NIOSH IDLH: 700 ppm
ROUTES OF EXPOSURE:
The
substance can be absorbed into the body by inhalation of its vapour and
by ingestion.
INHALATION RISK:
The substance can be
absorbed into the body by inhalation of its vapour and by ingestion. 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 irritates the
eyes, the skin and the respiratory tract. The substance may cause
effects on the heart and central nervous system, kidneys and liver ,
resulting in cardiac disorders and respiratory failure. Exposure at high
level may result in death. Medical observation is indicated.
