As far as we know, Inez Tenenbaum's first day on the job as chairman of the Consumer Product Safety Commission was quiet. Tomorrow will be a different story. In fact, it will be explosive.

In her first public appearance in her new role, Tenenbaum will oversee the agency's 10 A.M. event on fireworks safety. Part of the program includes demonstrating fireworks hazards on the National Mall.

As Tenenbaum starts to tackle the tough issues facing her agency—clarifying the Consumer Product Safety Inprovement Act and seeking relief for homeowners with toxic Chinese drywall—there may be more colorful displays to come.
