The Consumer Product Safety Commission said five deaths and 16 near-strangulations from Roman shades have been reported since 2006, while three deaths connected to roll-up blinds have been reported since 2001.
Roman shades can become dangerous, the CPSC said, if a child's neck gets stuck between the exposed inner cord and the fabric on the backside of the blind, or if the cord gets wrapped around a child's neck.
Roll-up blinds pose a strangulation threat if the lifting loop slides off the side of the blind and a child's neck becomes entangled on it, or if a child neck's gets between the lifting loop and the roll-up blind material.
The commission and the industry urged parents to examine all shades and blinds in the home and make sure they have no accessible cords. They also advised parents not to place cribs, beds or other furniture close to windows because children can climb on the furniture and reach the cords.
Cordless window coverings are recommended for all homes where children live or visit.
Several major retailers, including Wal-Mart, JCPenney and Pottery Barn, are also participating in the recall.
