Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Powder, water spray, foam, carbon dioxide. EXPLOSION Finely dispersed particles form explosive mixtures in air. Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting. EXPOSURE PREVENT DISPERSION OF DUST!  •INHALATION Cough. Avoid inhalation of dust. Fresh air, rest.  •SKIN  •EYES Safety goggles . First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Do not eat, drink, or smoke during work. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Personal protection: P1 filter respirator for inert particles. Sweep spilled substance into containers. R: S: SEE IMPORTANT INFORMATION ON BACK ICSC: 1487 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994.

International Chemical Safety Cards POLYVINYL CHLORIDE ICSC: 1487 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: WHITE POWDER , PELLETS PHYSICAL DANGERS: Dust explosion possible if in powder or granular form, mixed with air. CHEMICAL DANGERS: The substance decomposes on heating producing toxic fumes including hydrogen chloride and phosgene . Reacts violently with fluorine. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK: (as dust) 1.5 mg/m³ (Respirable fraction); (DFG 2004). ROUTES OF EXPOSURE: INHALATION RISK: A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. EFFECTS OF SHORT-TERM EXPOSURE: EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Lungs may be affected by repeated or prolonged exposure to dust particles , resulting in fibrosis (pneumoconiosis). PHYSICAL PROPERTIES Density: 1.41 g/cm3 Solubility in water: very poor ENVIRONMENTAL DATA N O T E S PVC products take many forms, due to additives used in manufacture. The additives can influence the physical and toxicological properties of this substance. The final product may contain traces of monomer see ICSC0082 Vinyl chloride.
