The Health Department also strongly encourages New Yorkers with children in one and two-family houses, which are not included in the Window Guards Law, to install window guards. Landlords or managers whose tenants have refused the installation of window guards where required should also call the Window Falls Prevention Unit at the same phone number. If your window guards are not installed yet, keep your bottom windows closed. Open only your top windows for fresh air. Furniture that children can climb on should not be near windows.
Some babies can climb up on furniture and crawl through open windows before they can even walk.
