The DuPont Bradley Curve
Designed to help clients understand and benchmark the journey toward world-class safety performance, this proven, proprietary system has helped enable safety success within DuPont, and for our clients around the world, since 1995.
Using the DuPont Bradley Curve, DuPont Sustainable Solutions consultants help our clients in diverse industries and countries to understand the development of an effective safety culture, from its earliest stages to a mature state.
In a mature safety culture, safety is truly sustainable, with injury rates approaching zero. People feel empowered to take action 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, as a whole, realizes significant business benefits in higher quality, greater productivity, and increased profits.
