TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames, NO sparks, and NO smoking.
Water spray, foam, powder, carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive.
Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT GENERATION OF MISTS!

Inhalation Dizziness. Drowsiness. Dullness. Nausea. Unconsciousness.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
Skin Dry skin. Roughness.
Protective gloves
Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes Redness. Pain.
Safety spectacles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion Burning sensation. (Further see Inhalation).
Do not eat, drink, or smoke during work.
Rinse mouth. Refer for medical attention.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer. Personal protection: self-contained breathing apparatus.
Marine pollutant.

1,1-DICHLOROETHANE ICSC: 0249
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
The vapour is heavier than air and may travel along the ground; distant ignition possible.

CHEMICAL DANGERS:
The substance decomposes on heating and on burning producing toxic and corrosive fumes including phosgene (see ICSC 0007) and hydrogen chloride (see ICSC 0163). Reacts violently with strong oxidants, alkali metals and earth-alkali metals, powdered metals, causing fire and explosion hazard. Attacks aluminium, iron and polyethylene. Contact with strong caustic will cause formation of flammable and toxic acetaldehyde gas.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 100 ppm as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004).
MAK: 100 ppm, 410 mg/m; Peak limitation category: II(2); Pregnancy risk group: D; (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and by ingestion.

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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the central nervous system. Exposure at high levels may result in unconsciousness.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin. The substance may have effects on the kidneys and liver.
PHYSICAL PROPERTIES
Boiling point: 57C
Melting point: -98C
Relative density (water = 1): 1.2
Solubility in water, g/100 ml at 20C: 0.6
Vapour pressure, kPa at 20C: 24
Relative vapour density (air = 1): 3.4
Flash point: -6C c.c.
Auto-ignition temperature: 458C
Explosive limits, vol% in air: 5.6-11.4
Octanol/water partition coefficient as log Pow: 1.8

NOTES
Do NOT use in the vicinity of a fire or a hot surface, or during welding. Card has been partly updated in October 2005. See sections Occupational Exposure Limits, EU classification, Emergency Response.
