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. NO contact with strong oxidants.
Alcohol-resistant foam, powder, carbon dioxide. NO water.
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: cool cylinder by spraying with water but avoid contact of the substance with water.
EXPOSURE
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
 •INHALATION Burning sensation. Cough. Laboured breathing. Shortness of breath. Sore throat. Symptoms may be delayed (see Notes).
Closed system and ventilation.
Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention. See Notes.
 •SKIN Skin burns. Blisters. Pain. Redness.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
 •EYES Redness. Pain. Severe deep burns.
Face shield, 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. Burning sensation. Shock or collapse.
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Do NOT induce vomiting. Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Evacuate danger area! Consult an expert! Ventilation. Remove all ignition sources. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in dry sand or inert absorbent and remove to safe place. Do NOT wash away into sewer. (Extra personal protection: gas-tight chemical protection suit including self-contained breathing apparatus).
Fireproof. Separated from strong oxidants, food and feedstuffs and incompatible materials . See Chemical Dangers. Cool. Dry. Well closed.
Airtight. Unbreakable packaging; put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs.

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID , WITH PUNGENT 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 producing toxic and irritating fumes including hydrogen chloride and phosgene . Reacts on contact with water or steam producing toxic and corrosive hydrogen chloride. Reacts violently with strong oxidants causing fire and explosion hazard. Reacts with amines , bases . Attacks many metals especially in the presence of moisture.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK:
Carcinogen category: 3B
(DFG 2008).


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 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
Tear drawing. The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. Inhalation of the vapour may cause lung oedema (see Notes).

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
PHYSICAL

Auto-ignition temperature: 500°C
Explosive limits, vol% in air: 3.2-27.5
thermal decomposition: > 250 °C
ENVIRONMENTAL
DATA

N O T E S
Health effects of exposure to the substance have not been investigated adequately. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered. Environmental effects from the substance have not been investigated adequately.
