TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.

In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION


EXPOSURE
STRICT HYGIENE!
IN ALL CASES CONSULT A DOCTOR!
 •INHALATION Abdominal pain. Cough. Sore throat. Headache. Nausea. Vomiting. Dizziness. Drowsiness. Confusion. Tremor. Convulsions.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
 •SKIN MAY BE ABSORBED! Redness. Dry skin. (Further see Inhalation).
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
 •EYES Redness. Pain.
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. Nausea. Vomiting. (Further see Inhalation).
Do not eat, drink, or smoke during work.
Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Rest. Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING

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

PHYSICAL DANGERS:
The vapour is heavier than air.

CHEMICAL DANGERS:
The substance decomposes on heating and under influence of air , UV light and moisture producing toxic and corrosive gases including hydrogen chloride , phosgene . Reacts violently with alkali metals , strong bases and powdered metals producing toxic and corrosive gases . Attacks plastic and rubber.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 1 ppm as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2005).
MAK: 1 ppm, 7.0 mg/m³
Peak limitation category: II(2);
skin absorption (H);
Carcinogen category: 3B; Pregnancy risk group: D;
(DFG 2006).
OSHA PEL: TWA 5 ppm (35 mg/m3) skin
NIOSH REL: Ca TWA 1 ppm (7 mg/m3) skin See Appendix A See Appendix C (Chloroethanes)
NIOSH IDLH: Ca 100 ppm See: 79345


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour, through the skin 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:
The substance is irritating to the eyes , the skin and the respiratory tract . The substance may cause effects on the central nervous system , liver and kidneys , resulting in central nervous system depression and impaired functions . Exposure may result in unconsciousness. Exposure may result in death.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin. The substance may have effects on the central nervous system and liver , resulting in impaired functions .

ENVIRONMENTAL
DATA
Environmental Hazard placard The substance is toxic to aquatic organisms.
N O T E S
Use of alcoholic beverages enhances the harmful effect. The odour warning when the exposure limit value is exceeded is insufficient. 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 section Storage.
Transport Emergency Card: TEC (R)-61S1702 or 61GT1-II
Card has been partially updated in July 2007: see Occupational Exposure Limits.
