Sight Specific Risk Assessment – Used in more private-sector redevelopment efforts, this approach is employed to establish cleanup levels because it typically yields the lowest cleanup cost estimates. Under this approach, cleanup levels for contaminants in the soil are not based on generic criteria set by governmental regulations for different land uses, but on criteria established for a specific site or for a level of exposure protection based on risk.

System Safety Risk Assessment

Site Specific Risk Assessment. A method of deriving site-specific criteria and engineering solutions for clean-up of a contaminated site. In Ontario an SSRA must be approved by the MOE pursuant to the Guideline for use at Contaminated Sites in Ontario. Now known as RA (see RA above).

Software Safety Requirements Analysis. Analysis performed to examine system and software requirements and the conceptual design in order to identify unsafe modes for resolution, such as out-of-sequence, wrong event, deadlocking, and failure-to-command modes.
