Phosphorus pentachloride

The substance is corrosive to the eyes, skin and respiratory tract. Inhalation of vapor may cause pulmonary edema (see Notes). Exposure far above OEL(Occupational Exposure Limit) could cause pulmonary edema. The effects may be delayed.

On burning toxic gases are formed. The solution in water is a strong acid, it reacts violently with bases and is corrosive. Reacts with water producing hydrogen chloride fumes and mist of phosphoric acid. In contact with air it emits corrosive fumes. Attacks plastic and rubber.

Lungs may be affected by inhalation of high concentrations of aerosol. The substance may have effects on the kidneys.
