CADMIUM OXIDE ICSC: 0117
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
ODOURLESS BROWN CRYSTALS OR AMORPHOUS POWDER.

CHEMICAL DANGERS:
Reacts violently with magnesium when heated causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: as Cd (total dust) 0.01 mg/m as TWA; (respirable fraction) 0.002 mg/m as TWA; A2 (suspected human carcinogen); BEI issued; (ACGIH 2005).
MAK: (Inhalable fraction); skin absorption (H); Carcinogen category: 1; Germ cell mutagen group: 3A; (DFG 2005).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion

INHALATION RISK:
A harmful concentration of airborne particles can be reached quickly when dispersed.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the respiratory tract. May cause mechanical irritation to the eyes. Inhalation of the aerosol may cause lung oedema (see Notes). Exposure far above the OEL may result in death. The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the kidneys and lungs, resulting in kidney impairment and tissue lesions. This substance is carcinogenic to humans.
PHYSICAL PROPERTIES
Sublimation point: (crystals) 1559C
Melting point (decomposes): (amorphous) 900-1000C
Density: 6.95 (amorphous); 8.15 (crystals) g/cm
Solubility in water: none
ENVIRONMENTAL DATA
Bioaccumulation of this chemical may occur in plants, in seafood. It is strongly advised that this substance does not enter the environment.
NOTES
Depending on the degree of exposure, periodic medical examination is suggested. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation is therefore essential. Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered. Do NOT take working clothes home.
