  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible but forms flammable gas on contact with water or damp air.  Risk of fire and explosion on contact with water or moisture.  NO open flames, NO sparks and NO smoking. NO contact with water or moisture.    Use powder, carbon dioxide. NO water.  In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water. Combat fire from a sheltered position. 

 AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS PREVENTION FIRST AID
Inhalation Burning sensation. Cough. Headache. Laboured breathing. Shortness of breath. Sore throat. Unconsciousness. Vomiting. Wheezing. Symptoms may be delayed. See Notes.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention. 
Skin Redness. Skin burns. Pain. Blisters.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Pain. Loss of vision. Severe deep burns.  Wear safety goggles, 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 refer for medical attention. 
Ingestion Abdominal pain. Burning sensation. Nausea. Shock or collapse. Further see Inhalation.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Refer for medical attention . See Notes. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Evacuate danger area! Consult an expert! Personal protection: chemical protection suit including self-contained breathing apparatus. Ventilation. Do NOT let this chemical enter the environment. Do NOT wash away into sewer. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. NEVER direct water jet on liquid.

THIOPHOSPHORYL CHLORIDE ICSC: 0581
PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
FUMING COLOURLESS LIQUID WITH PUNGENT ODOUR. 

Physical dangers
The vapour is heavier than air. 

Chemical dangers
Decomposes on heating and on contact with water and humidity. This produces toxic and corrosive fumes including phosphoric acid, hydrogen chloride and hydrogen sulfide. This generates fire and explosion hazard. Attacks many metals in the presence of water. 

Formula: Cl3PS
Molecular mass: 169.4
Boiling point: 125°C
Melting point: -35°C
Relative density (water = 1): 1.6
Solubility in water: reaction
Vapour pressure, kPa at 25°C: 2.9
Relative vapour density (air = 1): 5.8
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.1 


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation. 

Effects of short-term exposure
The substance is corrosive to the eyes, skin and respiratory tract. The vapour is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation of the vapour may cause lung oedema. See Notes. If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis. Exposure could cause death. The effects may be delayed. Medical observation is indicated. 

Inhalation risk
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C. 

Effects of long-term or repeated exposure
 


OCCUPATIONAL EXPOSURE LIMITS
 

ENVIRONMENT
This substance may be hazardous to the environment. Special attention should be given to water quality. 

NOTES
Reacts violently with fire extinguishing agents such as water, foam.
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 is therefore essential.
Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered.
