There is no consensus definition for lead-containing paint in industrial maintenance applications.
The following definitions have been developed for related applications: (1) CONSUMER

(calculated as lead metal) exceeds 0.06 percent by weight of the total nonvolatile content of the
paint or the weight of the dried paint film. The 0.06 percent level is equivalent to 600 ppm
[ILPR]; (2) RESIDENTIAL USE — A paint that contains at least 0.5 percent lead by weight of
the dried paint film. The 0.5 percent level is equivalent to 5000 ppm. Sometimes called lead paint
or leaded paint.
