Searching, assessment, and screening system for safter alternative chemicals, SAS
Petroleum; Crude oil (A complex combination of hydro carbons. It consists predominantly of aliphatic, alicyclic and aromatic hydrocarbons. It may also contain small amounts of nitrogen, oxygen and sulfur compounds. This category encompasses light, medium, and heavy petroleums, as well as the oils extended from tar sands. Hydrocarbonaceous materials requiring major chemical changes for their recovery or conversion to petroleum refinery feedstocks such as crude shale oils; upgraded shale oils and liquid coal fuels are not included in this definition.)

危害診斷模組是由以下四種計算化學方法構成,所預測之毒性警示提供參考,仍須與其他資料綜合評估:
安全替代物參考目前安全替代資料庫與軟體運作邏輯,分為以下三類:
系統依照子結構,列出風險等級為三級(可用、但可尋求更安全替代物)、四級(安全化學物質)、與資料不足(U、無足夠資料可供判別風險等級) 說明
