| 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. Butyl rubber or FEP Teflon gloves are recommended when handling NMP. A good skin cream should be used after washing the affected area. As with all solvents, the workplace should be well ventilated and safety goggles must be worn. Always refer to the Material Safety Data Sheet (MSDS) for detailed information on safety. |

|
| 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.
