  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.        In case of fire in the surroundings, use appropriate extinguishing media.   

   
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Sore throat.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness. Pain.  Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness. Pain. Blurred vision.  Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal pain. Vomiting. Diarrhoea. Shock or collapse.  Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. Do NOT induce vomiting. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered plastic containers. If appropriate, moisten first to prevent dusting. 

According to UN GHS Criteria

 

Transportation
UN Classification
UN Hazard Class: 8; UN Pack Group: III 

STORAGE

PACKAGING
 
FERRIC CHLORIDE (ANHYDROUS) ICSC: 1499
PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
BLACK-TO-BROWN HYGROSCOPIC CRYSTALS. 

Physical dangers
 

Chemical dangers
Decomposes above 200°C . This produces toxic and corrosive gases including chlorine and hydrogen chloride. Decomposes on contact with water. This produces hydrogen chloride. The solution in water is a medium strong acid. Reacts violently with alkali metals, allyl chloride, ethylene oxide, styrene and bases. This generates explosion hazard. Attacks metal. This produces flammable/explosive gas (hydrogen - see ICSC 0001). 

Formula: FeCl3
Molecular mass: 162.2
Melting point: 37°C
See Notes.
Density: 2.9 g/cm³
Solubility in water, g/100ml at 20°C: 92 (reaction)
Vapour pressure at 20°C: negligible 


EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. Corrosive on ingestion. 

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. 

Effects of long-term or repeated exposure
 


OCCUPATIONAL EXPOSURE LIMITS
 

ENVIRONMENT
The substance is harmful to aquatic organisms. 

NOTES
UN number 1773 corresponds to the anhydrous form; UN number 2582 corresponds to the solution.
The apparent melting point caused by loss of crystal water is given.
