4. FIRST AID MEASURES

General advice: Consult a physician, show this safety data sheet to the doctor in attendance, and move out of a 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 eyelids 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 the 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 firefighting 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.
• Evacuate personnel to safe areas.
• Avoid breathing dust.
• For personal protection see section 8.

Environmental precautions:

• Prevent further leakage or spillage if safe.
• Do not let the product enter drains.
• Discharge into the environment must be avoided.

Methods and materials for containment and cleaning up:

• Sweep up and shovel.
• Contain spillage, and then collect with an electrically protected vacuum cleaner or by wet brushing and place in a container for disposal according to local regulations (see section 12).
• Keep in suitable, closed containers for disposal.

7. HANDLING AND STORAGE

Conditions for safe storage, including any incompatibilities: Store in a tightly sealed container in a cool dry place away from combustible and flammable materials. If the container is left open, salt may adsorb water from the atmosphere.

Precautions for safe handling:

• Avoid contact with skin and eyes and the formation of dust and aerosols.
• Provide appropriate exhaust ventilation at places where dust is formed.
• Keep away from sources of ignition.
• Keep away from heat and sources of ignition.

8. EXPOSURE CONTROLS AND PERSONAL PROTECTION

Eye protection: Always wear approved safety glasses when handling a chemical substance in the laboratory.

Skin protection: Wear protective clothing and gloves.

Ventilation: If possible, handle the material in an efficient fume hood.

Respirator: If ventilation is not available a respirator should be worn. The use of respirators requires a Respirator Protection Program must follow 29 CFR 1910.134.

At any detectable concentration: Any self-contained breathing apparatus with a full facepiece operated in a pressure-demand or other positive-pressure mode.

Any supplied-air respirator with a full facepiece operated in a pressure-demand or other positive-pressure mode or other positive-pressure mode with an auxiliary self-contained breathing apparatus operated in pressure-demand or other positive-pressure mode.

Escape – any air-purifying, full-facepiece respirator with a high-efficiency particulate filler.

Any appropriate escape-type, self-contained breathing apparatus.

Clothing: Employees handling radioactive substances should wear disposable overgarments, including head and foot coverings. These garments are also recommended even if the employee uses a “glove box” containment system. Certain clothing fibers may be useful in dosimetry so clothing should be kept.

Gloves: The selection of appropriate gloves depends on the material, while the quality standards may vary among manufacturers.

Firefighting and Other Immediately Dangerous to Life or Health Conditions

Use any self-contained breathing apparatus with a full facepiece respirator and a high-efficiency particulate filter.

Use any supplied-air respirator with a full facepiece operated in a pressure-demand or other positive-pressure mode or other positive-pressure modes with an auxiliary self-contained breathing apparatus operated in pressure-demand or other positive-pressure modes.
