TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames.  Use water spray, powder. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!   
Inhalation Cough.  Use local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness. Pain.  Wear safety goggles or eye protection in combination with breathing protection if powder.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). 
Ingestion Diarrhoea. Nausea.  Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.  Do not transport with food and feedstuffs.
Unbreakable packaging.
Put breakable packaging into closed unbreakable container.

EMERGENCY RESPONSE SAFE STORAGE
  Provision to contain effluent from fire extinguishing. Separated from strong oxidants, strong acids and food and feedstuffs. Store in an area without drain or sewer access. 

IMPORTANT DATA
Physical State; Appearance
LIGHT YELLOW OR ORANGE CRYSTALS OR YELLOW-TO-BROWN POWDER. 

Physical dangers
 

Chemical dangers
Decomposes on burning. This produces toxic fumes including sulfur oxides. Reacts with strong oxidants. Reacts with acids. This produces toxic gas (hydrogen sulfide). 

Occupational exposure limits
TLV (as Cd respirable fraction): 0.002mg/m³ as TWA; A2 (suspected human carcinogen); BEI issued; (ACGIH 2007).
MAK (inhalable fraction): Carcinogen category: 1; Germ cell mutagen group: 3A; Skin absorption (H); (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 to the eyes. 

Effects of long-term or repeated exposure
The substance may have effects on the kidneys, bones and respiratory tract. This may result in kidney impairment, osteoporosis (bone weakness) and chronic inflammation of the respiratory tract. This substance is carcinogenic to humans. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Sublimation point: 980°C
Density: 4.8 g/cm³
Solubility in water: none 
Bioaccumulation of this chemical may occur in crustacea and plants. It is strongly advised not to let the chemical enter into the environment because it is persistent. 

NOTES
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.
