Staying Safe: Electronics Safety Rules

Part of the Electronics All-in-One For Dummies Cheat Sheet (UK Edition)

Safety first! Electronics is a potentially dangerous hobby. Any circuit that works with 230 VAC power from an electrical outlet is especially dangerous and can kill you. Here are some basic safety guidelines to keep you safe while you work:

  • Never work on a circuit while power is applied.

  • Don’t connect power to a circuit until the circuit is finished and you’ve checked your work carefully.

  • If you smell anything burning, immediately disconnect the power and examine your circuit to find out what went wrong.

  • Keep your work area dry.

  • Always wear safety goggles.

  • Be careful around large capacitors; they can continue to hold voltage long after they’re disconnected from power.

  • Be especially careful when you solder; a hot soldering iron can easily burn you.

  • Always work in a well-ventilated space.

  • Keep safety equipment nearby, such as a fire extinguisher, a first-aid kit and a phone.
