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.

Are flammables particularly hazardous substances? NO (not those in IsoLab)

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

The SDS for all acids can be found here. You should have taken EH&S Managing Laboratory Chemicals or similarly UW EH&S condoned course.

1. Process Many processes in IsoLab use flammable solvents. They are prevalent and abundant and lab personnel need to be aware of how to be safe around them.
2. Hazard Flammables currently in IsoLab's inventory include: ethanol, methanol, acetone, isopropanol, hexanes, estisol, dimethylformamide, sodium hydrosulfite, butane, propane, chromium powder, iron powder, acetic anhydride. Apart from flammability, each of these chemicals will have their own hazards and you need to read through the respective SDS for more information.
3. Personal Protective Equipment Wear flame-resistant lab coat and chemical splash goggles, consult Laboratory Safety Manual Appendix G for proper glove selection. Call EH&S (3-7388) for further information. A flame-resistant apron is recommended for personal protection and is required when dispensing or cleaning up spill quantities greater than 1 liter.
4. Environmental / Ventilation Controls Solvents should be dispensed only in a fume hood or in a well-ventilated space which has been approved and permitted by the Seattle Fire Department.
5. Special Handling Procedures & Storage Requirements Mixing or dispensing should be done in a hood with all sources of ignition eliminated (hot plates, burners, etc.). Solvents should be stored in appropriate flammable cabinets, separate from acids, bases, and oxidizers. Flammable cabinets located under fume hoods in 302A, 303B, and 302B.
6. Spill and Accident Procedures Remove all sources of ignition from the spill area if it is safe to do it. Small fires may be extinguished if it is safe and the operator is trained to use the fire extinguisher. Wipe down spill area with solvent absorbent pads. Solvent absorption pads are stored in Spill Kit cabinets in 302A, 303B, 302B.
7. Waste Disposal Label with Hazardous Waste Label, accumulate according to requirements, and send in Chemical Collection Request or Routine Pickup request, both available online at http://www.ehs.washington.edu/epowaste/chemwaste.shtm. Do not evaporate flammable solvents in the fume hood.
8. Special Precautions for Animal Use (if applicable) N/A
Particularly hazardous substance involved? NO, ignore 9-11
9. Approval Required


10. Decontamination N/A
11. Designated Area N/A
