Protect Children Protect Children, Pets from Radiator Antifreeze Fall and winter are peak times for automobile owners to change their radiator antifreeze, which is good for vehicle maintenance, but can lead to tragedy for children and pets, according to the Rocky Mountain Poison Center.
Ethylene glycol is the most common component of automobile radiator antifreeze.
While this compound may prevent the engine from overheating during the hot months and freezing during the cold, it can cause kidney failure and death if ingested by children or pets. Because antifreeze is commonly stored in home garages, it is a concern. Pets and children can have easy access to the colorful liquid when playing or exploring. Antifreeze has a pleasant, sweet taste that may be quite palatable when ingested. However, even a very small amount can cause significant injury.
