Mini Lesson

Staying safe means making choices that protect you and others from injury. Safety rules apply everywhere — at home, at the library, on the road, and outdoors. Knowing the difference between safe and unsafe behavior helps you prevent accidents before they happen.

Indoor Safety

  • Hold the handrail when going up or down stairs — rushing or jumping can cause falls.
  • Keep floors clear of toys, bags, and cables that could cause someone to trip.
  • Never play with sharp kitchen tools, electrical appliances, or cleaning chemicals.
  • Turn off electrical appliances when not in use and never use them near water.
  • In case of a fire, leave immediately, stay low under smoke, and call for help.

Outdoor Safety

  • Wear a helmet every time you ride a bicycle, scooter, or skateboard.
  • Look both ways before crossing the road — always use a marked crossing if one is available.
  • Apply sunscreen and wear a hat on sunny days to protect skin from harmful UV rays.
  • Only swim in supervised areas and never swim alone.
  • Do not climb trees or structures that are unstable or very high.

Road Safety

  • Stop, look, and listen before crossing any road.
  • Always walk on the sidewalk, not the road.
  • Wear bright or reflective clothing when out at dusk or night.
  • Never use headphones or a phone while crossing a road.

💡

Ask yourself: "Could this hurt me or someone else?" If the answer is yes, it is probably an unsafe behavior. When in doubt, ask a trusted adult.
