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

 PREVENT DISPERSION OF DUST!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough.  Avoid inhalation of dust and mist. Use local exhaust or breathing protection.  Fresh air. Seek medical attention if you feel unwell. 
Skin   Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
RED DELIQUESCENT POWDER. 

Physical dangers
No data. 

Chemical dangers
Decomposes on heating. This produces toxic and corrosive fumes including hydrogen chloride (see ICSC 0163). This generates toxic hazard. Reacts violently with iron pentacarbonyl and zinc. This generates explosion hazard. 

Formula: RhCl3 * 3 H2O / Cl3Rh * 3 H2O
Molecular mass: 263.3
Decomposes at 100°C
Relative density (water = 1): >1
Solubility in water: soluble 


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. 

Effects of short-term exposure
The substance is severely irritating to the eyes and possibly the respiratory tract. See Notes. 

Inhalation risk
A harmful concentration of airborne particles can be reached quickly , especially if powdered. 

Effects of long-term or repeated exposure
See Notes. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: (as Rh): 0.01 mg/m3, as TWA; A4 (not classifiable as a human carcinogen).
MAK: (as Rh): carcinogen category: 3 

ENVIRONMENT
 

NOTES
The name of rhodium chloride is often used both the hydrated and the anhydrous form.
Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
