2. Hazards Identification

Main Hazard Characteristics: This compound is thermally stable but may release toxic or irritating gases (such as ammonia and nitrogen) under high-temperature conditions.
Health Hazards: Direct contact may cause irritation to the skin, eyes, and respiratory tract.

3. First Aid Measures

Skin Contact: Immediately remove contaminated clothing and wash the skin thoroughly with soap and plenty of water.
Eye Contact: Immediately lift the upper and lower eyelids and flush thoroughly with flowing water or physiological saline for at least 15 minutes. Seek medical attention promptly.
Inhalation: Quickly move the patient to an area with fresh air and keep the airway open. If breathing is difficult, administer oxygen and seek medical attention immediately.
Ingestion: Do NOT induce vomiting. Rinse the mouth immediately, drink an appropriate amount of warm water, and seek medical attention immediately.

4. Fire Fighting Measures

Hazard Characteristics: Decomposes upon heating to release ammonia and nitrogen gases.
Extinguishing Agents: Firefighters must wear gas masks and full protective firefighting gear, and extinguish fires from upwind. Water mist, dry powder, foam, or carbon dioxide extinguishers can be used.

5. Accidental Release Measures

Personal Protection: Emergency responders must wear dust masks and appropriate protective equipment to avoid direct contact.
Environmental Handling: Cordon off the contaminated area and restrict access. Use clean shovels to collect the spilled material, place it in dry, clean, and covered containers, and dispose of it centrally.

6. Handling and Storage

Handling Precautions: Conduct operations in a closed system with local exhaust ventilation. Operators must be specially trained and strictly follow operating procedures. Keep away from open flames, heat sources, and strictly prohibit smoking in the workplace.
Storage Conditions: Store in a cool, dry, and well-ventilated warehouse at 2-8°C. Keep the container tightly sealed. Store separately from oxidizers; never store them together.

7. Exposure Controls and Personal Protection

Respiratory Protection: When dust concentration in the air exceeds the standard, a dust mask must be worn.
Eye Protection: Wear chemical safety goggles.
Body and Hand Protection: Wear general work protective clothing and rubber gloves.
