Ferric Chloride

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 Ferric chloride 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 ferric chloride can be found here.

1. Process Ferric chloride is used as part of selenium adsorption experiments.
2. Hazards Ferric chloride may be corrosive to metals, harmful if swallowed, may be fatal if swallowed and enters airways, causes severe skin burns and eye damage, causes serious eye damage, toxic if inhaled, may cause allergy or asthma symptoms or breathing difficulties if inhaled, suspected of causing genetic defects, may cause damage to organs, toxic to aquatic life, and is harmful to aquatic life. Refer to the SDS for more information.
3. Personal Protective Equipment While working with ferric chloride in a fume hood you should be wearing nitrile gloves, a lab coats, and eye protection. Do not work with ferric chloride outside of the fume hood.
4. Environmental / Ventilation Controls Ferric chloride is to be used in one of the fume hoods in the 302 / 303 suite. Ensure the fume hood has appropriate flow prior to working with ferric chloride. Do not work with ferric chloride unless the fume hood is functioning properly.
5. Special Handling Procedures & Storage Requirements Ferric chloride is stored in the west fume hood corrosives cabinet 303B. Make sure you have your laboratory coat, eye protection, and gloves on before handling the bottle.
6. Spill and Accident Procedures

Wear protective gloves and eye protection. In case of inadequate ventilation wear respiratory protection.

7. Waste Disposal All ferric chloride 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. 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 must have taken Managing Laboratory Chemicals or similar UW EH&S condoned course before using ferric chloride. You must have read and understood the SDS for Ferric chloride as well as this SOP. You also must review your process with previously trained laboratory personnel.

10. Decontamination Any glassware that has been used with ferric chloride should be rinsed such that the first rinse goes into the above mentioned waste container. Subsequent rinse or washing of glassware can be done outside the fume hood in the sink as per normal lab glassware cleaning procedures.
11. Designated Area Ferric chloride may only be used in a fume hood. Preferably the fume hood directly above its storage location.
