Safe handling
Fire: NO open flames, NO sparks and NO smoking. Above 35 °C use a closed system, ventilation and explosion-proof electrical equipment.
General: PREVENT GENERATION OF MISTS! AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!
Inhalation: Use ventilation, local exhaust or breathing protection.
Skin: Protective gloves. Protective clothing.
Eyes: Wear face shield or eye protection in combination with breathing protection.
Ingestion: Do not eat, drink, or smoke during work.
Storage
Fireproof. Separated from strong oxidants and acids. Dry.
Disposal
Package lots. Distill for reuse or package and label for disposal by burning. Small quantities. Wear eye protection, laboratory coat, and rubber gloves. Dissolve the morpholine (1 mL) in 50 mL of 3 M sulfuric acid (prepared by slowly adding 8 mL of concentrated sulfuric acid to 21 mL or water). Weigh 10 g of potassium permanganate and stir small portions of the solid into the morpholine solution over a period of about 1 hr. Stir the mixture at room temperature for 48 hr, and then neutralize the solution by adding solid sodium carbonate or a 10% solution of sodium hydroxide. Add solid sodium bisulfite until solution is colorless. Decant the clear liquid into the drain and discard any brown solid with regular refuse.
