In response to a request from the owner, an evaluation was made of potential hazardous conditions associated with the use of an experimental paint stripper to renovate wood floors by the Rosebud Company (SIC-1752), Atlanta, Georgia. The work was being performed at an antique residence undergoing renovation. The paint stripper, Experimental Solvent System Formulat MPB, was a viscous liquid used for passive refinishing. Personal exposures to n-methyl- pyrrolidinone (872504) (NMP) were documented at 3.3 and 4.0 parts per million (ppm) on two occasions at the work site. Area samples averaged 3.6 and 7.7ppm. No detectable lead (7439921) was found in the personal or area air samples taken. Wipe samples prior to renovation found a surface lead level of 158 micrograms per square foot from a section of baseboard. Four paint chip samples from the floor or a room being renovated contained 0.19% to 0.28% lead. Levels of formic-acid (64186) were below the 5ppm OSHA permissible exposure limit. The author concludes that the health hazard associated with NMP exposure is not clear. The author recommends that additional precautions be taken to reduce potential exposures for workers and others in the building.
