Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.
In case of fire in the surroundings: use appropriate extinguishing media.

Unbreakable packaging; put breakable packaging into closed unbreakable container.
EMERGENCY RESPONSE
SAFE STORAGE
Separated from incompatible materials. See Chemical Dangers.
IMPORTANT DATA
Physical State; Appearance RED DELIQUESCENT POWDER.
Chemical dangers The substance decomposes on heating producing toxic and corrosive fumes including hydrogen chloride (see ICSC 0163). Reacts violently with iron pentacarbonyl and zinc causing explosion hazard.
Occupational exposure limits TLV: 0.01 mg/m³ as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004). MAK: Carcinogen category: 3B; (DFG 2004).
Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.
Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.
PHYSICAL PROPERTIES
ENVIRONMENTAL DATA
Melting point (decomposes): 100°C Relative density (water = 1): >1 Solubility in water: very good
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. Card has been partly updated in October 2005. See sections Occupational Exposure Limits, Emergency Response.
