So the question is, what makes them so hazardous?
Antifreeze: Antifreeze or de-icing liquids prevent water from freezing on the windshield and make the scraping easier. Antifreeze is comprised of compounds that have lower freezing points like the toxic alcohol ethylene glycol. When ethylene glycol is ingested, it is converted to a toxic metabolite which causes damage to the kidneys and the brain. Antifreeze products are usually brightly colored which can be intriguing to a child and enhance the desire to drink.
Similar to ethylene glycol, methanol is a toxic alcohol which can be found in many antifreeze and de-icing products. Methanol can affect the central nervous system and cause seizures, coma, blindness and in severe cases methanol can be fatal. Even ingesting a small amount can be dangerous to children.
Rock Salt: There are various form of salts that are sprinkled on the road for melting ice. The most common salt is sodium chloride, and others include potassium chloride, calcium chloride, or magnesium chloride. One or two pebbles of these salts are unlikely to cause harm, but large amounts can cause significant tissue irritation. If children or pets come into contact with these salts, wash the exposed skin (or paws) immediately with a plenty of water and monitor for skin irritation.
Waterproof Spray: Fluorocarbon polymers or fluoropolymer are often found in waterproof sprays. When accidentally inhaled, this toxic substance can affect the lung and cause respiratory illness. Symptoms such as difficulty breathing, coughing, and/or chest pain can develop within minutes to hours of exposure. Children who are exposed to fluorocarbon polymer should seek medical help immediately.
Tips for safety:
Keep ice melting products out of sight and out of reach for children
Always keep them in the original containers
Be aware of the ingredients! Take a look the ingredient list on the back of the de-icing products
Clean shoes/boots before entering the house
