NO open flames, NO sparks, and NO smoking. Powder, AFFF, foam, carbon dioxide. EXPLOSION Vapour/air mixtures are explosive. Closed system, ventilation, explosion-proof electrical equipment and lighting. In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE PREVENT GENERATION OF MISTS!  •INHALATION Cough. Drowsiness. Headache. Sore throat. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.  •SKIN Dry skin. Redness. Pain. Protective gloves. First rinse with plenty of water, then remove contaminated clothes and rinse again. Refer for medical attention.  •EYES Redness. Pain. Safety goggles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Abdominal pain. Diarrhoea. Drowsiness. Headache. Nausea. Vomiting. Do not eat, drink, or smoke during work. Rinse mouth. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Ventilation. 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 wash away into sewer. (Extra personal protection: self-contained breathing apparatus). Fireproof. Provision to contain effluent from fire extinguishing.

International Chemical Safety Cards 1,2-DICHLOROPROPANE ICSC: 0441 I M P O R T A N T D A T A 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: On combustion, forms toxic and corrosive fumes. Attacks aluminum alloys and some types of plastics. OCCUPATIONAL EXPOSURE LIMITS: TLV: 75 ppm (as TWA); 110 ppm (as STEL) A4 (ACGIH 1998). OSHA PEL: TWA 75 ppm (350 mg/m3) NIOSH REL: Ca See Appendix A NIOSH IDLH: Potential occupational carcinogen 400 ppm 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: The substance irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the central nervous system. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The liquid defats the skin. The substance may have effects on the liver and kidneys.
