Imagine a hypothetical situation in which 250 mL of diethyl ether has spilled inside of a chemical fume hood onto a stir plate that is plugged in and stirring. Discuss the risks associated with this situation (location, size, compound spilled, and external hazards), and then explain how this spill should be managed.

 

Diethyl ether is an organic ether solvent which is highly reactive. It may only be handled, opened, and dispensed is under a fume hood. The spill of 250 mL of diethyl ether is considerably a small spill (less than 1L). It is highly flammable and explosive. The compound can instantly be ignited by heat sources or static electricity. The situation can cause flame because there is a plugged stir plate inside the fume hood. Additionally, it can explode when it exposed to light and air due to the formation of reactive peroxides. Possible external hazards include irritation to the skin and eyes, dizziness when inhaled, and acute toxicity when ingested.

A small and contained spill can be handled by an authorized laboratory personnel. Inside a fume hood, use non-flammable absorbent pills to absorb the spill. Also, the clean-up materials must not dry in air, so it is important to seal them immediately. In case of fire, use a suitable extinguisher, particularly one that uses dry chemical, chemical foam, carbon dioxide, or alcohol-resistant foam. Water is not recommended as an extinguisher. Properly label the chemical waste bags. If the situation cannot be managed, call for assistance.
