Lumkani is a fire alarm designed especially for informal settlements.
The alarm is networked using radio frequency, so when a fire is detected nearby, it will sound to warn neighbors to help.
Fire spreads quickly in townships like Khayelitsha because the densely-packed houses are often made of cardboard, wood, and corrugated tin. Narrow alleyways also mean homes are difficult for fire services to access.
The Red Cross has worked with Lumkani in Khayelitsha to distribute hundreds of the devices.
The system was engineered by a Cape Town university student, who teamed up with five co-founders to form the start up.
