Oxygen-rich places like ICUs and operating rooms are tricky when it comes to electrical safety. There’s just more danger—fires and explosions become a real threat if something goes wrong with the wiring. Higher oxygen levels make it way easier for sparks to start a fire, especially if you’ve got things like leakage currents, worn-out insulation, or equipment acting up. Most of the time, you protect against electrical faults with things like fuses and circuit breakers. They do their job by cuttin
