Gives off irritating or toxic fumes (or gases) in a fire. NO contact with water. NO water. In case of fire in the surroundings: powder, carbon dioxide . EXPLOSION In case of fire: cool drums, etc., by spraying with water but avoid contact of the substance with water. EXPOSURE AVOID ALL CONTACT!  •INHALATION Sore throat. Cough. Burning sensation. Shortness of breath. Laboured breathing. Symptoms may be delayed (see Notes). Local exhaust or breathing protection. Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.  •SKIN 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. Shock or collapse. Abdominal pain. Do not eat, drink, or smoke during work. Rinse mouth. Do NOT induce vomiting. Give plenty of water to drink. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Evacuate danger area! Do NOT wash away into sewer. Sweep spilled substance into sealable containers. Carefully collect remainder, then remove to safe place. Personal protection: complete protective clothing including self-contained breathing apparatus.

International Chemical Safety Cards PHOSPHORUS PENTACHLORIDE ICSC: 0544 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: FUMING WHITE TO YELLOW CRYSTALS , WITH PUNGENT ODOUR. PHYSICAL DANGERS: The vapour is heavier than air. CHEMICAL DANGERS: The substance decomposes on heating producing toxic and corrosive fumes including hydrogen chloride and phosphorus oxides . Reacts violently with water or moisture to form phosphoric acid and hydrogen chloride. Reacts with many compounds, causing fire and explosion hazard. Attacks many metals forming flammable/explosive gas (hydrogen - see ICSC 0001). Attacks plastic and rubber. OCCUPATIONAL EXPOSURE LIMITS: TLV: 0.1 ppm as TWA; (ACGIH 2004). MAK: (Inhalable fracion) 1 mg/m³ Peak limitation category: I(1); Pregnancy risk group: IIc; (DFG 2004). OSHA PEL: TWA 1 mg/m3 NIOSH REL: TWA 1 mg/m3 NIOSH IDLH: 70 mg/m3 ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its vapour 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 corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. Inhalation of this substance may cause lung oedema (see Notes). The effects may be delayed. Medical observation is indicated. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. PHYSICAL PROPERTIES Sublimation point: 100°C Relative density (water = 1): 1.6 Solubility in water: reaction Vapour pressure, Pa at 55.5°C: 133 Relative vapour density (air = 1): 7.2 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.2 ENVIRONMENTAL DATA N O T E S Reacts violently with fire extinguishing agents such as water. 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 inhalation therapy by a doctor or a person authorized by him/her, should be considered. Card has been partly updated in October 2004.
