From the American Red Cross, April 11, 2017: Cambridge homeowners who would like a free photoelectric smoke alarm installed should call the local Red Cross registration service at (800) 746-3511.

The American Red Cross will install free smoke alarms where needed on the Saturdays of May 20 and June 3 starting at 9 a.m. as part of its Home Fire Campaign.

Seven times a day someone in this country dies in a home fire, according to the Red Cross. Countless others suffer injuries. The Red Cross’ nationwide campaign aims to reduce the number of deaths and injuries due to home fires by 25 percent, with its workers joining with fire departments and community groups to visit neighborhoods at high risk. Those visits include educating people about fire safety through door-to-door visits and installing smoke alarms. To date the Massachusetts program has been to more than 2,500 homes in 200 cities and towns; nationwide, more than 500,000 alarms have been installed in 50 states.

As part of these events, local Red Cross volunteers will also teach residents how to prevent a home fire and how to prepare to respond in the event a fire starts in their home.
