The OECD QSAR Toolbox is software designed to support hazard assessment of chemicals as well as to increase mechanistic and other knowledge on chemical substances in a cost-efficient way. As a freely available computational tool, it promotes the use of assessment methods alternative to animals and minimizes unnecessary animal testing without reducing the safety of human health and environment. It is intended to be used by governments, chemical industry and other stakeholders..............

It's free and may be a useful addition to your own hazard assessment "toolbox".

There is a website that describes the "tool" and where you can download a copy for free LINK HERE 

HPAPI does not warrant the quality of any output that the OECD QSAR Toolbox delivers.  It is up to the user to assess the level of reliance that may be placed on the tool.
