U.S. Sen. Amy Klobuchar is joining other lawmakers in pushing for quicker action to prevent kids from getting strangled in window cords.

According to Klobuchar’s office, the Consumer Product Safety Commission estimates one child in the United States dies from window cord strangulation each month. In June, the Window Covering Manufactures Association announced it would develop revised safety standards to combat those statistics.

“Several recent tragic events underscore the need for swift action to complete the voluntary standard. In the last six weeks alone, four children have died from window blind cord injuries. These are preventable deaths and we cannot afford to wait any longer to have an effective voluntary standard in place,” the lawmakers wrote.

Sen. Bill Nelson (D-FL), Rep. Jan Schakowsky (D-IL) and Sen. Frank Oakkibe (D-NJ) are also involved in the effort.
