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: all extinguishing agents allowed.
EXPLOSION

EXPOSURE		PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!	IN ALL CASES CONSULT A DOCTOR!
Inhalation	Cough. Laboured breathing. Shortness of breath. Symptoms may be delayed (see Notes).	Closed system and ventilation.	Fresh air, rest. Half-upright position. Refer for medical attention.
Skin	Redness.	Protective gloves.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes	Redness. Pain.	Safety goggles, or eye protection in combination with breathing protection if powder.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion	Abdominal cramps. Diarrhoea. Nausea. Vomiting.	Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Refer for medical attention.

CADMIUM OXIDE

ICSC: 0117

IMPORTANT DATA

PHYSICAL STATE; APPEARANCE:
ODOURLESS, BROWN CRYSTALS OR AMORPHOUS POWDER.

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic fumes of cadmium. Reacts violently with magnesium when heated causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: ppm; 0.01 mg/m^3 (as TWA) (as Cd); total dust A2 (ACGIH 1993-1994). TLV (as TWA): ppm; 0.002 mg/m^3 (as Cd); respirable dust A2 (ACGIH 1993-1994).

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, especially if powdered.

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

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Lungs may be affected by repeated or prolonged exposure. The substance may have effects on the kidneys and lungs , resulting in kidney impairment and tissue lesions. This substance is probably carcinogenic to humans. Animal tests show that this substance possibly causes toxic effects upon human reproduction.

PHYSICAL PROPERTIES

Sublimation point: (crystals) 1559°C
Melting point (decomposes): 900-1000°C (amorphous)°C
Relative density (water = 1): 6.95 (amorphous); 8.15 (crystals)
Solubility in water: none

ENVIRONMENTAL DATA

In the food chain important to humans, bioaccumulation takes place, specifically in plants and seafood. It is strongly advised not to let the chemical enter into the environment because it persists in the environment.

NOTES

Depending on the degree of exposure, periodic medical examination is indicated. 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 are therefore essential. Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered. Do NOT take working clothes home.
