Is it possible to work with pao ferro (Machaerium scleroxylum, Tul.)?

ABSTRACT

Pao ferro (Machaerium scleroxylum), used as a rosewood substitute, is a strong sensitizer capable of causing acute outbreaks of allergic and irritant dermatitis in workers not previously exposed to it. This, however, has not prevented furniture factories from using the product. Apparently, most workers develop tolerance to the wood.
