History

RTECS was an activity mandated by the US Congress, established by Section 20(a)(6) of the Occupational Safety and Health Act of 1970 (PL 91-596). The original edition, known as the ''Toxic Substances List'' was published on June 28, 1971, and included toxicological data for approximately 5,000 chemicals. The name changed later to its current name ''Registry of Toxic Effects of Chemical Substances''. In January 2001 the database contained 152,970 chemicals. In December 2001 RTECS was transferred from NIOSH to the private company Elsevier MDL and is now only accessible for charge on an annual subscription base.
RTECS® is available in English, French and Spanish language versions, offered by the Canadian Centre for Occupational Health and Safety. The database subscription is offered on the Web, on CD-ROM and as an Intranet format. The database is also available online from NISC (National Information Services Corporation).
