V.   HEALTH HAZARD INFORMATION

Effects of Over Exposure:

Acute overexposure to cadmium compounds may result in lung injury with persistent cough, dyspnea and pulmonary edema (chemical pneumonia).  However, these acute effects have occurred primarily following exposure to cadmium oxide fume.  Dust of insoluble compounds, such as this material, are considered to be less toxic than cadmium fume.  Chronic exposure may lead to pulmonary emphysema and/or kidney damage.  The renal dysfunction is characterized by the urinary excretion of low molecular weight proteins.  Ingestion may cause nausea, vomiting, diarrhea, and abdominal pain.

Route(s) of Entry:  Material can be inhaled, swallowed or come in contact with the skin or eyes.

Carcinogenic assessment (NTP annual report, IARC monographs, Other):  Cadmium sulfide has been identified as being carcinogenic in laboratory animals by the NTP and IARC.  This conclusion was based on the production of local sarcomas following subcutaneous and intramuscular injection.


EMERGENCY AND FIRST AID PROCEDURES:

INHALATION:  Remove from exposure.  Seek medical attention.

INGESTION:  If substantial quantities are swallowed, give person (if conscious) a large quantity of water to drink, induce vomiting and seek medical attention.

SKIN:  Thoroughly wash affected area with mild soap and a large volume of water.  If irritation persists, seek medical attention.

EYE:  If irritation occurs, flush with copious amounts of water.  If irritation persists, seek medical attention.

 

 

VI.   REACTIVITY DATA

Stability:  Stable

Conditions to Avoid:  N/A

Incompatibility (Material to Avoid):  Contact with acids generates hydrogen sulfide gas.

Hazardous Decomposition Products:  Oxide of sulfur, zinc oxide and cadmium oxide.

Hazardous Polymerization:  Will not occur.

 

 

VII.   SPILL OR LEAK PROCEDURES

Steps to Be Taken in Case Material Is Released or Spilled:  Ventilate area of spill.  Clean-up using methods which avoid dust generation such as vacuuming (with appropriate filter to prevent airborne dust levels which exceed the PEL or TLV), wet dust mop or wet clean-up.  If airborne dust is generated, use an appropriate NIOSH approved respirator.

Waste Disposal Method:  Dispose of in accordance with Local, State and Federal regulations.

 

 

VIII.   SPECIAL PROTECTION INFORMATION

Respiratory Protection (Specify Type):  Use a appropriate NIOSH approved respirator if airborne dust concentrations exceed the TLV or PEL.  All appropriate requirements set forth in 29 CFR 1910.134 should be met.

Ventilation:  Use local exhaust ventilation which is adequate to limit personal exposure to levels which do not exceed the TLV or PEL.  If such equipment is not available, use respirators as specified above.

Protective Gloves:  Gloves are recommended when contact is likely.

Eye Protection:  Safety glasses or goggles are recommended.

 

 

IX.   SPECIAL PRECAUTIONS

Precautions to Be Taken in Handling and Storage:  Maintain good housekeeping procedures to prevent accumulation of dust.  Use clean-up methods which minimize dust generation such as vacuuming or wet clean-up.  If airborne dust is generated, use an appropriate NIOSH approved respirator.

Other Precautions:  Wash thoroughly after handling and before eating or smoking and at the end of the work shift.  Do not shake clothing or other items to remove dust.  Use a vacuum.  Avoid dust inhalation and direct skin contact.  Do not ingest.  Periodic medical examinations are recommended for individuals regularly exposed to dust.
