Cobalt III 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 Cobalt(III) fluoride a particularly hazardous substance? YES
What is a particularly hazardous substance? The University of Washington Environmental Health and Safety defines it here.
|1. Process||Cobalt(III) fluoride (CoF3) is used as a fluorinating agent to convert water to O2 and HF. The O2 is analyzed for isotope composition and the HF is vented to the hood.|
|2. Hazards||Cobalt(III) fluoride (CoF3) is an acute toxin, an oxidizer, and carcinogenic. It will create hydrofluoric acid (HF) on contact with water. Refer to the SDS for more information.|
|3. Personal Protective Equipment||While working with CoF3 in a fume hood, you should be wearing nitrile gloves and a lab coat and have all of your utensils, supplies, and the CoF3 in a secondary container. Ideally, you would use an glove box filled with Argon. However, sometimes this can create more of a mess than without. Do not work with CoF3 outside of the fume hood.|
|4. Environmental / Ventilation Controls||CoF3 is to be used in one of the fume hoods in 303B or the fume hood in 302A. Ensure the fume hood has appropriate flow prior to working with CoF3. Do not work with CoF3 unless the fume hood is functioning properly.|
|5. Special Handling Procedures & Storage Requirements||CoF3 is stored in a desiccator on the North Wall in 303B. Make sure you have gloves on before grabbing the reagent bottle.|
|6. Spill and Accident Procedures||
CoF3 is a buoyant powder.
Use personal protective equipment. If a large spill is outside of fume hood, don a respiratory mask located in 303B near the balances in addition to a laboratory coat, nitrile gloves, and goggles. Avoid dust formation. Avoid breathing dust. Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided. Pick up and arrange disposal without creating dust. Sweep up and shovel. Keep in suitable, closed containers for disposal.
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 CoF3 into the designated waste container.
|7. Waste Disposal||All CoF3 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 CoF3. You must have read and understood the SDS for CoF3 as well as this SOP.|
|10. Decontamination||Make sure all CoF3 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||CoF3 may be handled in the fume hoods in 303B or the fume hood in 302A.|
