4. FIRST AID MEASURES

Description of necessary measures according to routes of exposure

Swallowed

Do NOT induce vomiting. Wash mouth with water. If symptoms develop, seek medical attention.

Eye

Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the eyelids. If irritation persists, seek medical attention.

Skin

Wash affected area with soap and water. If symptoms develop, seek medical attention.

Inhaled

Remove from exposure to fresh air immediately. Apply artificial respiration if not breathing. Seek medical attention.

Advice to Doctor

Treat symptomatically based on individual reactions of patient and judgement of doctor.

Additional Information

Aggravated medical conditions caused by exposure

No information available on chronic health effects from this product.

5. FIRE FIGHTING MEASURES

Extinguishing Media

In case of fire, appropriate extinguishing media include water spray, dry extinguishing media, foam and carbon dioxide.

Hazards from Combustion Products

Stable under normal conditions of use and storage. Contact with acids liberates very toxic gas. Under fire conditions, this product will emit toxic and irritating fumes including hydrogen fluoride. Avoid contact with moisture, acids, bases and sources of ignition.

Fire fighters should wear a self contained breathing apparatus and full protective clothing along with protective equipment.

Special protective precautions and equipment for fire fighters

No Data Available

Flammability Conditions

Product is non-flammable.

Additional Information

Hazchem Code : 2Z

6. ACCIDENTAL RELEASE MEASURES

Emergency procedures

Personnel involved in the clean up should wear full protective clothing. Eliminate all sources of ignition. Do not allow product to enter drains, sewers or waterways. Increase ventilation. Avoid raising dust.

Methods and materials for containment and clean up

Sweep up spilled product – avoid raising dust and place in a suitable, labelled container. Add slowly, calcium hydroxide or calcium carbonate to the remaining NaF in order to render it calcium fluoride.

7. HANDLING AND STORAGE

Precautions for safe handling

Ensure an eye bath and safety shower are available and ready for use.

Conditions for safe storage, including any incompatibles

Store in a cool, dry, well-ventilated area out of direct sunlight and moisture. Store in labelled, corrosion-resistant containers. Keep containers tightly closed when not in use. Store away from water, base, acids and sources of ignition. Inspect periodically for defeciencies such as damage or leaks. This product is classified as a Class 6.1 – Toxic and Infectious Substances Dangerous Good according to the Australian Code for the Transport of Dangerous Goods by Road and Rail. This product can not be transported in a placard load with explosives, flammables, corrosive materials and is incompatible with food and food packaging in any quantity.
