Physical State; Appearance:
LIGHT YELLOW OR ORANGE CRYSTALS
OR YELLOW TO BROWN POWDER.
Physical Dangers:
Chemical Dangers:
The substance decomposes on burning producing toxic fumes including sulfur oxides.
Reacts with strong oxidants.
Reacts with acids forming toxic gas (hydrogen sulfide).
Occupational Exposure Limits:
TLV: as Cd
(Respirable fraction)
as TWA; 0.002 mg/m3 A2 (suspected human carcinogen); BEI issued (ACGIH 2007).

(DFG 2006).
|
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, especially if powdered.
Effects of Short-Term Exposure:
May cause mechanical irritation to the eyes.
Effects of Long-Term or Repeated Exposure:
The substance may have effects on the kidneys, bones, and respiratory tract
, resulting in kidney impairment, osteoporosis (bone weakness), and chronic inflammation of the respiratory tract.

N O T E S
|
|
There is little information on the effects of this compound. Health effects are here mainly based on the studies of other cadmium compounds.
Depending on the degree of exposure, periodic medical examination is suggested.
Welding and soldering of surfaces treated with cadmium sulfide release highly toxic cadmium oxide which may cause acute lung injury (see ICSC 0117 - cadmium monoxide).
Do NOT take working clothes home.
Cadmium golden 366, Cadmium lemon yellow, Cadmium orange, Cadmium primrose 819, Cadmium yellow 10G conc., Cadmium yellow conc. primrose, Cadmopur golden yellow N, Cadmopur yellow, Capsebon, Ferro lemon yellow are trade names.
