TYPES OF HAZARD / EXPOSURE | ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
FIRE | Explosive.
Gives off irritating or toxic fumes (or gases) in a fire. |
NO open
flames, NO sparks, and NO smoking. NO contact with acid(s) or oxidants. NO
contact with hot surfaces. |
Water spray,
foam, carbon dioxide, NO dry chemical. |
EXPLOSION | Vapour/air
mixtures are explosive. |
Closed
system, ventilation, explosion-proof electrical equipment and lighting. Do
NOT expose to friction or shock. |
Combat fire
from a sheltered position. In case of fire: keep cylinder cool by spraying
with water. |
EXPOSURE | STRICT
HYGIENE! |
||
Inhalation | Headache.
Nausea. Vomiting. Sore throat. Dizziness. Facial paralysis, numbness and
tremor. |
Closed
system and ventilation. |
Fresh air,
rest. Refer for medical attention. |
Skin | Protective
gloves. |
Rinse and
then wash skin with water and soap. | |
Eyes | Redness.
|
Safety
spectacles, or eye protection in combination with breathing protection.
|
First rinse
with plenty of water for several minutes (remove contact lenses if easily
possible), then take to a doctor. |
Ingestion | Abdominal
pain. (Further see Inhalation). |
Do not eat,
drink, or smoke during work. |
Refer for
medical attention. Rinse mouth. |
SPILLAGE DISPOSAL | PACKAGING & LABELLING | |||||||

IMPORTANT DATA | |||
PHYSICAL
STATE; APPEARANCE: OILY LIQUID, WITH CHARACTERISTIC ODOUR. CHEMICAL DANGERS: May decompose explosively on shock, friction, or concussion. May explode on heating. The substance decomposes on heating producing toxic fumes including chlorine. Reacts violently with oxidants and with acids. OCCUPATIONAL EXPOSURE LIMITS: TLV: (Ceiling value) 0.1 ppm A3 (ACGIH 2001). MAK: Carcinogen category: 2 (DFG 2000). |
ROUTES OF
EXPOSURE: The substance can be absorbed into the body by inhalation of its vapour. INHALATION RISK: A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance may cause effects on the nervous system and kidneys, resulting in tissue lesions, impaired functions and kidney impairment. | ||
PHYSICAL PROPERTIES | |||
Boiling
point: 32°C (explodes) Melting point: -66°C Relative density (water = 1): 1.2 Solubility in water: none Relative vapour density (air = 1): 3.3 |
Flash point:
see Notes | ||
ENVIRONMENTAL DATA | |||
NOTES | |||
The substance is combustible but no flash point is available in
literature. Combustion in a confined space may turn into detonation. The
occupational exposure limit value should not be exceeded during any part
of the working exposure. The substance is not commercially available, but
it is a decomposition product of trichlorethylene, trichloroethane and it
is also a by-product of vinylidene chloride. | |||
