The state of Maryland is considering a similar proposal to ban the sale of bumper pads, and the federal agency responsible for regulating consumer products — the Consumer Product Safety Commission — has said since December that it is investigating the issue.

The trade group that represents the makers and sellers of bumper pads says the products are safe and insists there is no evidence of a causal connection between crib bumpers and suffocation.

Rick Locker, general counsel for that group, the Juvenile Products Manufacturers Association, has said banning bumpers could bring about unintended consequences, such as parents putting pillows and adult blankets in babies’ cribs if bumper pads aren’t available.On Wednesday, the ordinance passed a joint health and consumer protection committee meeting despite opposition from industry representatives.

"This is our attempt to sound the alarm that something has to be done," said Cardenas, chairman of the Committee on Health and Environmental Protection.

Cardenas and other aldermen acknowledged that the task of overseeing product safety should fall to federal regulators but said nothing has been done.

"If they don't get their act together, municipalities like Chicago will have to do it on their own," Cardenas said.

In December the Tribune reported that federal regulators have failed to warn parents that bumpers pose a suffocation risk even though they know about the potential hazard.

It's unclear exactly how many babies have died from suffocating against the products, but the Tribune found that the federally funded National Center for Child Death Review has since 2008 received 14 reports of infant suffocation in which a bumper was relevant in the death.

Babies often lack the motor skills and strength to turn their heads if they roll against something that blocks their breathing.

Federal regulators have said they are trying to determine if there is a scientific link between bumper pads and suffocations, or if factors such as blankets, pillows or medical issues played the primary role in the deaths. However, the Tribune found that regulators did not investigate at least 17 reports of children's deaths even though the agency had reports on file suggesting bumper pads played roles in the fatalities.
