  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.   

 PREVENT DISPERSION OF DUST!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Cough.  Avoid inhalation of dust and mist. Use local exhaust or breathing protection.   
Skin Redness.  Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness.  Wear safety spectacles.   
Ingestion   Do not eat, drink, or smoke during work.   

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. 

According to UN GHS Criteria

 

Transportation

RHODIUM TRICHLORIDE, TRIHYDRATE ICSC: 0746
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). Reacts violently with iron pentacarbonyl and zinc. This generates explosion hazard. 

Formula: Cl3Rh. 3H2O
Molecular mass: 263.3
Decomposes at 100°C
Relative density (water = 1): >1
Solubility in water: very good 


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
 

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

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.
