EXPOSURE
STRICT HYGIENE!

INHALATION Cough. Laboured breathing. Nausea. Sore throat.
Ventilation.
Fresh air, rest. Refer for medical attention.
SKIN Redness. Pain.
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
EYES Redness. Pain.
Face shield.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
INGESTION Burning sensation. Vomiting (further see Inhalation).
Do not eat, drink, or smoke during work.
Rinse mouth.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place (extra personal protection: complete protective clothing including self-contained breathing apparatus).

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID , WITH PUNGENT ODOUR.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
On contact with hot surfaces or flames this substance decomposes forming toxic fumes of chlorinated compounds. Reacts violently with strong oxidants or metals. On contact with air it emits corrosive fumes (hydrogen chloride).

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV not established.
PDK: 0.5 mg/m3 (USSR 1993).


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

INHALATION RISK:
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes, the skin and the respiratory tract.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
This substance is possibly carcinogenic to humans.
