The DuPont™ Bradley Curve™, a proven, proprietary system, helps
clients comprehend and benchmark their journey to world-class safety
performance. Since 1995, it’s enabled an effective safety culture for
both DuPont and our worldwide clients.
With the DuPont™ Bradley Curve™, DSS consultants help organizations
in a wide range of industries around the world to better understand
the effectiveness of a successful safety culture — from early stages
through maturity (sustainable with injury rates near zero).
In 2009, a DSS study using the Bradley Curve showed a direct
correlation between an organization’s cultural strength and an
organization’s safety culture, including injury frequency rate and
sustainable safety performance. Using data collected in the
Safety Perception Survey™ since 1999, the DuPont™ Bradley Curve™
shows that a successful safety culture empowers people, while
improving quality, productivity and profits.
In a mature safety culture (interdependent stage), safety is truly
sustainable, with injury rates approaching zero. People feel empowered
to act as needed to work safely. They support and challenge each
other. Decisions are made at the appropriate level and people live by
those decisions. The organization realizes significant business
benefits through higher quality, greater productivity and increased profits.

believe accidents will happen.
Dependent Stage - People view safety as following rules.
Accident rates decrease.
Independent Stage - People take responsibility and
believe they can make a difference with actions. Accidents reduce further.
Interdependent Stage - Teams feel ownership and
responsibility for safety culture. They believe zero injuries is an
