Here is a concise summary of the content:
**Title:** Safety of Using Electronics in the Bathtub
**Key Points:**
1. **GFCI Outlets Save Lives**: Ground Fault Circuit Interrupter (GFCI) outlets in bathrooms can prevent electrocution if an electrical device falls into water.
2. **Isolated Chargers are Safe**: Phone chargers with isolated outputs are safe to use in bathtubs, even if the phone falls in water.
3. **Danger Lurks with Non-Isolated Devices**: Hair dryers and other non-isolated devices can be deadly if used in bathtubs, emphasizing the need for GFCI outlets.
4. **Regulatory Gaps**: Countries with lax regulations may have higher electrocution risks due to non-compliant, cheap electronics (e.g., non-isolated chargers).
5. **Safety Tips**:
* Always use GFCI outlets in bathrooms.
* Avoid using electronics in bathtubs.
* Don't buy questionable, non-compliant electronics.
**Additional Context:**
* The content is presented in a video format, with the creator conducting experiments to demonstrate electrical safety principles.
* The video is sponsored by Keysight, which is running an IoT Innovation Challenge for students, with prizes including cash and equipment for their universities.
Here are the key facts extracted from the text, keeping each fact a short sentence and numbered for reference:
**Electrical Safety Facts**
1. Ground Fault Circuit Interrupter (GFCI) outlets are designed to prevent electrical shock in bathrooms.
2. GFCI outlets detect current flowing between live and earth and shut down to prevent shock.
3. In North American bathrooms, GFCI outlets are mandatory.
4. The output of a phone charger is typically isolated from live wires, making it relatively safe.
5. Isolation in chargers prevents current from flowing through the body if the charger is in contact with water.
**Incident Reports and Statistics**
6. According to reports, five people died in Russia within a year from electrical shock while using their plugged-in mobile phone in the bath.
7. Multiple cases of electrical shock in bathtubs have been reported, mostly in countries with less stringent product regulations.
**Product Safety Concerns**
8. Non-isolated phone chargers may exist in markets with minimal government regulations.
9. A "suicide showerhead" with exposed wires has been sold on Amazon, posing a significant electrical shock risk.
10. Such products often require bypassing ground fault protection to function, increasing danger.
**General Safety Advice**
11. Always plug electronics in bathrooms into GFCI-protected outlets.
12. It's more dangerous to remove an electrical appliance from water than to leave it in, as current may flow through the body.
13. Never bring live wires into a bathtub or shower.
14. Avoid using questionable knockoff electronics, especially in bathrooms.
