Here's the abstract:

  This SRFI provides two libraries for use with R7RS that provide
  a way to sandbox the eval procedure to make it safer to use in
  evaluating Scheme expressions of doubtful provenance.  The
  intention is to call eval, passing it an S-expression
  representing a Scheme procedure and the environment defined by
  one of these libraries.  Since code evaluated by eval runs in a
  null lexical environment, the resulting procedure can then be
  invoked with less concern about possible side effects.

Regards,

SRFI Editor
