Título M-Pyrol (NMP) use in the microelectronics industry
Información bibliográfica Oct. 1991, Vol.6, No.10, p.874-880. Illus. 18 ref.
Resumen The cyclic amide, N-methyl-2-pyrrolidone, or M-Pyrol, is commonly encountered in the microelectronics industry as a solvent used primarily for dissolving plastic materials. Preliminary toxicological information is emerging documenting properties of M-Pyrol as a severe eye irritant. Prolonged skin contact can lead to severe irritation. No threshold limit value (TLV) has been established for M-Pyrol; however, the GAF Corporation currently recommends a time-weighted average (TWA) value of 100ppm. Initial evaluations during this study of worker exposure to the chemical indicate that severe eye irritation and headaches are experienced at levels as low as 0.7ppm in air for even short periods of time (30 minutes). In order to prevent eye irritation and headaches, it is recommended that worker exposures to M-Pyrol vapour do not exceed 0.1ppm (skin).
