Standard Operating Procedures

Magnesium Perchlorate

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 Magnesium perchlorate 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 Magnesium perchlorate can be found here.

1. Process Magnesium perchlorate is used as a desiccant for CNS isotope analysis in the two elemental analyzers attached to Shrek, for nitrous oxide isotope analysis in the Precon attached to Irene and to create a dry air stream for all of the Picarro lasers.
2. Hazards Magnesium perchlorate (Mg(ClO4)2) is a powerful oxidizer and may intensify a fire. It will cause skin, eye, and respiratory irritation. Refer to the SDS for more information.
3. Personal Protective Equipment While working with Mg(ClO4)2 in a fume hood, you should be wearing nitrile gloves. Do not work with Mg(ClO4)2 outside of the fume hood, near reducing agents, near an open flame, or near very hot surfaces.
4. Environmental / Ventilation Controls Mg(ClO4)2 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 Mg(ClO4)2. Do not work with Mg(ClO4)2 unless the fume hood is functioning properly.
5. Special Handling Procedures & Storage Requirements Mg(ClO4)2 is stored on the North Wall of 303B. Make sure you have gloves on before grabbing the reagent container. Close the Mg(ClO4)2 container with the appropriate lid when not in use.
6. Spill and Accident Procedures

All personnel without PPE should leave the room if there is a large spill outside of the fume hood. Dust may present an irritation. 

Use personal protective equipment. If 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 should 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 Mg(ClO4)2 into the designated waste container.

7. Waste Disposal All Mg(ClO4)2 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 Mg(ClO4)2. You must have read and understood the SDS for Mg(ClO4)2 as well as this SOP.
10. Decontamination Make sure all Mg(ClO4)2 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 Mg(ClO4)2 may be handled in the fume hoods in 303B or the fume hood in 302A.
