Sodium Fluoride

This chemical standard operating procedure (SOP) is for your safety. Read, understand, and follow this document. If this is a paper copy, you should check for the most recent version on the IsoLab website. This document was created from a template modeled after the University of Washington Environmental Health and Safety Laboratory Safety Manual Standard Operating Procedures Components.

Is Sodium fluoride a particularly hazardous substance? YES

What is a particularly hazardous substance? The University of Washington Environmental Health and Safety defines it here.

The SDS for Sodium fluoride can be found here.

1. Process Sodium fluoride (NaF) is used as part of bacterial growth experiments and has been used for water fluorination.
2. Hazards Sodium fluoride (NaF) is toxic if swallowed, causes skin irritation, and causes serious eye irritation. Refer to the SDS for more information.
3. Personal Protective Equipment While working with NaF in a fume hood, you should be wearing nitrile gloves, a laboratory coat, and protective eyewear. Do not work with NaF outside of the fume hood.
4. Environmental / Ventilation Controls NaF is to be used in the fume hoods in 302 or 303. Ensure the fume hood has appropriate flow prior to working with NaF. Do not work with NaF unless the fume hood is functioning properly.
5. Special Handling Procedures & Storage Requirements NaF is stored on the South Wall shelf in 302B. Make sure you have gloves on before grabbing the reagent bottle.
6. Spill and Accident Procedures

Avoid contact with skin, eyes and clothing. Use personal protective equipment. Ensure adequate ventilation. Avoid dust formation. Keep in suitable, closed containers for disposal. Do not flush into surface water or sanitary sewer system.

If you need further assistance, during business hours, call EH&S at 206.543.0467 or if after hours, call 911 and ask for EH&S assistance. When necessary EH&S will obtain a chemical spill cleanup contractor at the lab’s expense.

Spill materials are a hazardous waste. Report the spill via the EH&S Online Accident Reporting System (OARS).

If the spill occurred in and is completely contained in the fume hood, clean up all material using wipes and paper towels. Discard all materials that have come into contact with NaF into the designated waste container.

7. Waste Disposal All NaF waste is contained in an appropriate labeled tightly sealable plastic, wide-mouth, container. Do not open the waste container unless it is contained in a fume hood. Excessively soiled wipes used for cleanup, must go into the waste container. Contact EH&S for waste removal when the container is sufficiently full or aged.
8. Special Precautions for Animal Use (if applicable) N/A
Particularly hazardous substance involved? YES, see 9-11
9. Approval Required You should have taken Managing Laboratory Chemicals or similar UW EH&S condoned course before using NaF. You must have read and understood the SDS for NaF as well as this SOP.
10. Decontamination Make sure all NaF has been cleaned up and contained in appropriate containers before moving away from the fume hood. Ensure all utensils and trays have been wiped clean before removing them from the fume hood.
11. Designated Area NaF may be handled in the fume hoods in 303B or the fume hood in 302A.
