4. FIRST AID MEASURES

General advice: Consult a physician, show this safety data sheet to the doctor in attendance, and move out of dangerous area.

Eye exposure:

• Immediately flush the eyes with copious amounts of water for at least 10-15 minutes.
• A patient may need assistance in keeping their eye lids open.

Skin exposure:

• Wash the affected area with water.
• Remove contaminated clothes if necessary.
• Seek medical assistance if irritation persists.

Inhalation:

• Remove the patient to fresh air.
• Closely monitor the patient for signs of respiratory problems, such as difficulty in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance.

Ingestion:

• Keep the patient calm.
• Give the patient water (only if conscious).
• Induce vomiting only if directed by medical personnel.

5. FIREFIGHTING MEASURES

Extinguishing medium: Carbon dioxide or dry powder.

Special firefighting procedures:

• Spray closed containers with water until fire is out.
• Avoid contact with combustible material.
• Firefighters should be equipped with a NIOSH approved self-contained breathing apparatus.

Hazardous combustion and decomposition products: If involved in a fire, this material may emit corrosive hydrogen chloride fumes.

Unusual fire or explosion hazards:

• Releases oxygen on heating.
• May decompose explosively under fire fighting conditions.
• Do not mix with combustibles.

6. ACCIDENTAL RELEASE MEASURES

Personal precautions, protective equipment, and emergency procedures:

• Use personal protective equipment.
• Avoid dust formation.
• Avoid breathing vapors, mist, or gas.
• Ensure adequate ventilation.
