Wear protective gloves, laboratory coat, goggles, and breathing apparatus if necessary. Cover spill with a 1 1 1 mixture by weight of soda ash, clay cat litter (bentonite), and sand. Scoop the mixture into a plastic container and either label and send for disposal by burning,4 6 or, in the fume hood, add the mixture to a solution of potassium hydroxide in ethanol allowing 0.12 mol (7.9 g) of 85% potassium hydroxide pellets and 32 mL of ethanol for each 0.1 mol (12.4 g) of ethyl methanesulfonate to be destroyed. Heat the mixture under reflux for 8 hours. Decant the cooled solution into the drain with water. Treat the solid as normal refuse.6...
