Can a circuit board shock you?

Circuit boards are also susceptible to electrical shock. As PCBs are usually not openly exposed to the environment, direct lighting strikes are not a great threat; although, high current on input power supply lines are possible and can create board damage through shorts.

Is it safe to touch a PCB?

Can you get lead poisoning from circuit boards?

And circuit boards often contain poisonous metals that are used in the manufacturing process, including mercury and lead. Both of these can have profound health effects in humans. Lead toxicity can cause anemia, irreversible neurological damage, cardiovascular effects, gastrointestinal symptoms, and renal disease.

Is it safe to touch ground wire?

Grounding wires, especially on the exterior of your home through grounding rods are exposed. The grounding wires are safe to touch unless there is an electrical surge that causes electricity to flow through the grounding wire.
