TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.

In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION


EXPOSURE
PREVENT DISPERSION OF DUST!

 •INHALATION Cough.
Avoid inhalation of fine dust and mist. Local exhaust or breathing protection.

 •SKIN Redness.
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
 •EYES Redness.
Safety spectacles.

 •INGESTION
Do not eat, drink, or smoke during work.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Personal protection: P3 filter respirator for toxic particles.
Separated from incompatible materials . See Chemical Dangers.
Unbreakable packaging; put breakable packaging into closed unbreakable container.
ICSC: 0746 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

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

ENVIRONMENTAL
DATA


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.
