Important Data
|
Physical State; Appearance:
RED
DELIQUESCENT POWDER.
Physical Dangers:
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.
Effects of Short-Term Exposure:
Effects of Long-Term or Repeated Exposure:
|
|
Physical
Properties
|
Melting point (decomposes): 100°C
Relative density (water = 1): >1
|
Solubility in water:
very good

N O T E S
|
|
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.
