TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Powder, water spray, foam, carbon dioxide.
EXPLOSION

In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
AVOID ALL CONTACT!

 •INHALATION Burning sensation. Cough. Sore throat. Symptoms may be delayed (see Notes). Coma.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
 •SKIN MAY BE ABSORBED! Pain. Redness. Blisters. Skin burns.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
 •EYES Pain. Redness. Severe deep burns. Loss of vision.
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 Burning sensation. Abdominal pain. Shock or collapse.
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention.
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. Do NOT let this chemical enter the environment. (Extra personal protection: complete protective clothing including self-contained breathing apparatus).
Separated from food and feedstuffs. Well closed. Ventilation along the floor. Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing.
Do not transport with food and feedstuffs.
Severe marine pollutant.
UN Hazard Class: 6.1

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

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on burning producing toxic and corrosive fumes including hydrogen chloride and phosgene. Attacks rubber and some forms of plastic.

OCCUPATIONAL EXPOSURE LIMITS:
TLV (as TWA): 0.02 ppm; 0.21 mg/m A3 (skin) (ACGIH 1997).
MAK: skin absorption (H);
Carcinogen category: 3B
(DFG 2008).
OSHA PEL: none
NIOSH REL: Ca TWA 0.02 ppm (0.24 mg/m3) skin See Appendix A
NIOSH IDLH: Ca N.D. See: IDLH INDEX


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 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The vapour irritates the eyes, the skin and the respiratory tract. The liquid is corrosive. The substance may cause effects on the kidneys.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization. May cause genetic damage in humans.
