Wood preservation was stablished in Brazil by 1902 in order to provide treated sleepers for railways, since there was a shortage of durable hardwoods in area served by railways. The growing need of sleepers and poles together with the availability of Eucalyptus spp. contributed for the development of wood preservation. Many wood preservation plants started to be stablished in 1957, and in 1977 their total number was 34, most of them for treatment of sleepers and poles with pentachlorophenol, creosote, CCA and CCB, all made in Brazil. Wood preservation research has been carried out since 1931, but there are few specialists in Brazil. Federal Governmental laws, Brazilian standards, the stablishment of ABPM (Brazilian Wood Preservers' Association), and the IBDF-IPT-ABPM Contract are the main causes for recent development of wood preservation in Brazil.
