Hazards and Protection.
Storage
Keep cadmium nitrate tetrahydrate well closed in a cool place. Store at ambient temperature with open venting.
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Protection
Wear skin protection and industrial filter mask. Intense heat will necessitate self-contained breathing apparatus.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Keep away from combustible materials. Avoid contact unless wearing appropriate protective clothing. Stop leak if you can do it without risk. With clean shovel place material into clean, dry container and cover loosely; move containers from spill area.
Stability
Stable.
Incompatibilities
May react explosively.
Decomposition
When heated to decomposition, emits very toxic fumes of cadmium and nitrogen oxides.

Fire.
Fire fighting
Small Fires: Use water. Do not use dry chemicals or foams. carbon dioxide or Halon may provide limited control. Large Fires: Flood fire area with water from a distance.
Fire potential
Nonflammable.
Hazards
Cadmium nitrate will increase the intensity of fire when in contact with combustible material. Tetrahydrate mixtures with wood or other combustibles may catch fire. Tetrahydrate
Combustion products
Toxic oxides of nitrogen and cadmium oxide fume may form in fires.

Poison_Class
1
Exposure effects
Throbbing headache is common. Seizures have been reported following severe intoxication. Behavioral deficits were observed in the adult offspring of rats who received sodium nitrite prenatally.
   Ingestion
Initial effects of ingestion are gastric irritation with nausea, vomiting and abdominal pain.
   Inhalation
Respiratory depression and cyanosis may be noted, due to methemoglobinemia.
   Skin
Cyanosis that minimally responds to oxygen therapy may be noted, and is indicative of probable methemoglobinemia.
   Eyes
See Skin.

First aid
 
   Ingestion
Give large amounts of water and induce vomiting; give milk or egg whites; seek medical attention.
   Inhalation
Remove patient to fresh air; seek medical attention.
   Skin
Wash with soap and water.
   Eyes
Flush with copious amounts of water for 15 min.; consult a physician.
