Stay safe

Great inventors are safe inventors. Follow these rules every time you build.

Electricity and tools

  • Only use batteries or USB power. Never touch, open or connect anything to a wall socket.
  • Unplug the power before you change any wires.
  • Check that + goes to + and − goes to − before connecting a battery.
  • If something gets hot, smells like burning or makes smoke, unplug it at once and get help.
  • Learn safe soldering from someone experienced before using a soldering iron. It is hot enough to burn skin instantly.
  • Never use a swollen, damaged or leaking battery.
  • Keep water and drinks away from your project table.

Internet safety

  • Never share personal details, such as your home address or phone number, in a public project.
  • Use a strong, unique password for every online account.
  • Keep your WiFi password secret, even in code you share online.
  • Do not point a camera project at people without their permission.
