SAFETY
Care should be used when handling NMP. Skin contact should be avoided. Contact can result in irritation; prolonged contact can result in redness and dermatitis. Butylrubber or FEP Teflon gloves are recommended when handling NMP. A good skincream should be used after washing the affected area. As with all solvents, the workplace should be well ventilated and safety goggles must be worn.
 

STORAGE & HANDLING
 
NMP has an almost unlimited shelf life in sealed containers when properly stored in a protected storage area in original unopened containers or protected from moisture. It is neither explosive nor spontaneously flammable in air. However, it is combustible. When ignited, NMP will sustain a fire. All types of fire extinguishers are effective against NMP fires.
