Model answer: Get out of the house right away and go to your family's meeting spot outside. Do not stop to grab toys or belongings. Stay low to the ground if there is smoke. Once you are outside, stay there and wait for a grown-up.
A smoke alarm means there could be a fire, and the most important thing is to get out quickly. Smoke rises, so staying low keeps you below the worst of it. Every family should have a plan for where to meet outside so that everyone can be accounted for. Never go back inside a building that might be on fire.
