TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE See Chemical dangers.   In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST!  
Inhalation Cough. Local exhaust or breathing protection. Fresh air, rest.
Skin   Protective gloves. Rinse and then wash skin with water and soap.
Eyes Redness. Safety goggles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion   Do not eat, drink, or smoke during work. Rinse mouth.

SPILLAGE DISPOSAL PACKAGING & LABELLING
Sweep spilled substance into covered containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Personal protection: P2 filter respirator for harmful particles.  

EMERGENCY RESPONSE SAFE STORAGE
  See Chemical Dangers.

IMPORTANT DATA

GREY TO BLACK POWDER.

Chemical dangers
Reacts violently with halogens causing fire hazard. Rhodium is a catalytic substance and may cause reaction in contact with many organic and inorganic substances, causing fire and explosion hazard.

Occupational exposure limits
TLV: 1.0 mg/m³ as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004).
MAK: Carcinogen category: 3B; (DFG 2004).

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed.

Effects of short-term exposure
May cause mechanical irritation.


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 3695°C
Melting point: 1965°C
Density: 12.4 g/cm³
Solubility in water: none
 

NOTES
Health effects of exposure to the substance have not been investigated adequately.
Recommendations in this card do not apply to water-soluble rhodium compounds.
