**Title:** Investigating the Tragic Electrocution of a 14-Year-Old Girl in a Bathtub
**Summary:**
* A 14-year-old girl (Madison) was tragically electrocuted in a bathtub, allegedly while using her mobile phone.
* The narrator investigates the incident, explaining how electrocution can occur in a bathtub (via live wire contact) but concludes that a standard phone charger's isolated, low-voltage output poses no lethal risk if dropped in water.
* Initially, the narrator speculates about possible scenarios, but an update reveals the actual cause:
+ Madison used an extension cord with exposed, frayed power lines to charge her phone in the bathtub.
+ Unaware of the hazard, she touched the exposed area, leading to the tragedy.
* Key takeaways:
1. Avoid using electronics in bathtubs, especially with extension cords.
2. Never use damaged extension cords.
3. Proposed safety improvement: modifying North American plugs to prevent exposed contacts when live.
Here are the key facts extracted from the text, numbered and in short sentences:
**Incident Facts**
1. A 14-year-old girl, Madison, was electrocuted in her bathtub.
2. She had been using her mobile phone in the bathtub while it was charging.
3. According to her grandmother, Madison dropped the phone in the tub and tried to pick it up when the incident occurred.
4. Madison had burn marks on her hand.
**Electrical Safety Facts**
5. Bathwater, especially soapy water, is highly conductive.
6. The human body has a resistance of over 100 kilo-ohms, but this can be significantly lowered in water.
7. Standard wall adapters have isolated outputs from input live and neutral lines.
8. Mobile phone chargers output around 5 volts, which is non-lethal.
9. Dropping a phone in water does not typically lead to electrocution if the charger and phone are designed to safety standards.
**Investigation and Cause**
10. Initial speculation about the cause was later proven incorrect by new information.
11. Madison's family shared that the charger cord was too short, leading her to use a frayed extension cord.
12. The extension cord had exposed power lines, which Madison unknowingly touched, causing the electrocution.
13. Neither the phone nor the charger was dropped in the water, contrary to initial reports.
**Safety Recommendations**
14. Using electronics in the bathroom is safest when done on battery power.
15. Damaged extension cords should never be used as they can cause fires or electrocution.
16. A proposed safety measure includes redesigning North American plugs to prevent exposure to live contacts when plugged in.
