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! AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
•INHALATION Cough. Laboured breathing. Shortness of breath. Symptoms may be delayed (see Notes).
Local exhaust or breathing protection.
Fresh air, rest. Half-upright position. Refer for medical attention.
•SKIN

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.

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

PHYSICAL DANGERS:


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

OCCUPATIONAL EXPOSURE LIMITS:
TLV: as Cd (total dust) 0.01 mg/m3 as TWA;
(respirable fraction)
0.002 mg/m3 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).
OSHA PEL*: 1910.1027 TWA 0.005 mg/m3 *Note: The PEL applies to all Cadmium compounds (as Cd).
NIOSH REL*: Ca See Appendix A *Note: The REL applies to all Cadmium compounds (as Cd).
NIOSH IDLH: Ca 9 mg/m3 (as Cd) See: IDLH INDEX


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) 1559°C
Melting point (decomposes): (amorphous) 900-1000°C
Density: 6.95 (amorphous); 8.15 (crystals)
g/cm3
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.

N O T E S

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.
