The Fire Dept. of New York — and other fire safety organizations — promote the time changes in fall and spring as a reminder to change your smoke detector batteries — doing so saves lives and property. As someone who lost a lot of her childhood comics in a fire that was undetected by a fire alarm, I can testify that this is a really great cause and a good reminder.

Last week, even Spider-Man got into the act, along with firemen and FDNY Fire Safety mascot Hot Dog. The FDNY provided some pictures and says you can follow along on twitter at @fdnynews. Here’s some more info from the press release:

*Smoke alarms and carbon monoxide detectors are very powerful tools that can help save your life and the lives of your family,* said Commissioner Cassano.  *But with that great power, comes great responsibility.  I urge everyone to take a few minutes to change the batteries in their smoke alarms and carbon monoxide detectors when they change their clocks this weekend.  Those few minutes can help keep you and your family safe and alive.*

The FDNY Fire Safety Education Unit has held over 4,700 fire safety presentations educating approximately 430,000 New Yorkers in 2010. At these events, they have distributed nearly 15,000 smoke alarms and 56,000 batteries, with an additional 30,000 batteries to be distributed by the end of the year.

Last month, the FDNY and FDNY Foundation launched a new fire safety website, www.fdnyfiresmart.org.  This website offers videos, interactive games and tips for children, parents and seniors, as well as detailed lesson plans for teachers.
