Every line below is in CPSC’s own words, with its source beside it.
What’s wrong with it?
The antifreeze products contain the substance ethylene glycol which must be in child resistant packaging as required by the Poison Prevention Packaging Act. The products’ caps were not rotated enough during manufacturing to engage the child resistant mechanism, posing a risk of poisoning if the contents are swallowed by young children.

What should you do?
Consumers should immediately inspect the product and twist the cap to ensure the child resistant mechanism is engaged.
