American Red Cross is installing 100,000 free smoke detectors nationwide in 100 different cities for their campaign called Sound the Alarm.
The campaign's goal is to reduce deaths due to fires.
Since 2014, the organization has installed nearly 1,000,000 smoke alarms and saved about 270 lives.
Pat Eger with the American Red Cross says they work with local fire departments to find out which neighborhoods are at high risk.
"Unfortunately, mobile homes catch fire and they go up so fast that people have less time," she said. "We look at mobile homes first, we look at populations that maybe can't afford smoke alarms, maybe they are elderly and can't move as fast so again we want to give them as much warning."
The Southern Arizona chapter is tasked with installing 1,000 alarms between September 23- October 15 and they are looking for help.
They need about 150 volunteers to give out safety information, create escape plans and install smoke alarms.
