First Aid Measures

Ingestion
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Get medical aid. Wash mouth out with water.
Inhalation
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid if cough or other symptoms appear.
Skin
Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists. Wash clothing before reuse.
Eyes
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.

Handling and Storage

Storage
Store in a cool, dry, well-ventilated area away from incompatible substances.
Handling
Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Do not ingest or inhale.

Hazards Identification

Inhalation
May cause respiratory tract irritation.
Skin
May cause skin irritation.
Eyes
May cause eye irritation.
Ingestion
Ingestion of large amounts may cause gastrointestinal irritation. Ingestion of large amounts may cause nausea and vomiting, rigidity or convulsions. Continued exposure can produce coma, dehydration, and internal organ
EC Risk Phrase

EC Safety Phrase
S 24/25

Exposure Controls/Personal Protection

Personal Protection
Eyes: Wear safety glasses with side shields. Skin: Wear appropriate gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to minimize contact with skin.
Respirators
A NIOSH/MSHA approved air purifying dust or mist respirator or European Standard EN 149.
Exposure Effects
Hypernatremia may produce restlessness, irritability, dizziness, progressive obtundation, reduced salivation, tearing, seizures and coma. Hyperosmolarity of cerebral fluids may lead to cellular crenation and irreversible neurologic damage.
Poison Class
-

Fire Fighting Measures

Fire Fighting
Fires involving this chemical can be controlled with a dry chemical, carbon dioxide, foam or Halon extinguisher.

Accidental Release Measures

Small spills/leaks
Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions.

Stability and Reactivity

Disposal Code
14
Incompatibilities
Reacts with most nonnoble metals such as iron or steel, building materials (such as cement), bromine, or trifluoride. Potentially explosive reaction with dichloromaleic anhydride + urea. Electrolysis of mixtures with nitrogen compounds may form explosive nitrogen trichloride.
Stability
Stable under normal shipping and handling conditions.
Decomposition
Toxic fumes of sodium oxide.
