Why Do Fire Stations Still Use Sirens?

Growing up in southwestern Pennsylvania, I lived next to railroad tracks and a fire station. Coal-carrying trains, which rumbled through town at all hours of the day and night, could be tolerated. But occasionally I’d be startled awake by the deafening wail of a fire siren.

With the advent of modern technology and advanced emergency notification systems, are sirens still necessary? It isn't just me who wondered this, either; communities across the country have been raising the same question at their local meetings, with some addressing the issue as early as the 1990s. As it turns out, sirens technically aren’t necessary, and whether or not they’re used at all is a local decision, according to the National Volunteer Fire Council.

Although no law mandates their use, many departments have fought to keep them in place, despite complaints from annoyed residents. Chris Hash, of the Easton Volunteer Fire Department in Maryland, wrote in a blog post that sirens are needed because other communication devices, like pagers and cell phones, are not infallible.

“Batteries die, pagers and cell phones are not on the person, and text messaging and smartphone apps like Active 911 are often delayed, with some calls not coming through at all,” Hash wrote. “The National Fire Protection Association recommends that there are at least two reliable means to alert firefighters [of an emergency].”

Plus, there’s no missing or mistaking a fire siren. "When you're out working in the yard on a lawn mower, you can't hear your pager, but you can hear that siren,” George McBride, a member of the Hillcrest Volunteer Fire Department in Mechanicville, New York—where a debate arose over whether to replace a siren that had been disconnected—told the Times Union in 2014.

In addition to notifying firefighters of an emergency, the siren is also used to let local residents know they should remain alert. Some advocates of the fire siren argue that it lets drivers and pedestrians know they should stay off the roads, and residents with sprinklers are reminded to turn them off to conserve water.

One fire department in Mitchell, Ontario, hadn’t used its fire siren in nearly a decade, but after a firefighter nearly struck a pedestrian while driving to the fire hall, the town decided to start using it again earlier this year. Another department in Calistoga, California, considered purchasing a siren in the aftermath of a deadly wildfire, even though they had gotten rid of it years before in response to noise complaints.

More have joined suit. Duncan Scott, a sales manager at Federal Signal, told the Napa Valley Register in April that departments from all over California have placed orders for sirens after a number of wildfires swept through the state.

Other communities have struck a balance by keeping their sirens, but limiting their usage during hours when most people are sleeping. Of course, in some small towns, sirens still sound daily at noon or sundown—a holdover from a time when sirens were used to let residents know when it was time for lunch or for their children to come inside. Some communities keep this going for the sake of tradition.

What's the Difference Between Memorial Day and Veterans Day?

It may not be easy for some people to admit, but certain national holidays often get a little muddled—namely, Memorial Day and Veterans Day. In fact, the U.S. Department of Veterans Affairs sees the confusion often enough that they spelled out the distinction on their website. The two days are held six months apart: Veterans Day is celebrated every November 11, and Memorial Day takes place on the last Monday of May as part of a three-day weekend with parades and plenty of retail sales promotions. You probably realize both are intended to acknowledge the contributions of those who have served in the United States military, but you may not recall the important distinction between the two. So what's the difference?

Veterans Day was originally known as Armistice Day. It was first observed on November 11, 1919, the one-year anniversary of the end of World War I. Congress passed a resolution making it an annual observance in 1926. It became a national holiday in 1938. In 1954, President Dwight D. Eisenhower changed the name from Armistice Day to Veterans Day to recognize veterans of the two world wars. The intention is to celebrate all military veterans, living or dead, who have served the country, with an emphasis on thanking those in our lives who have spent time in uniform.

We also celebrate military veterans on Memorial Day, but the mood is more somber. The occasion is reserved for those who died while serving their country. The day was first observed in the wake of the Civil War, where local communities organized tributes around the gravesites of fallen soldiers. The observation was originally called Decoration Day because the graves were adorned with flowers. It was held May 30 because that date wasn't the anniversary for any battle in particular and all soldiers could be honored. (The date was recognized by northern states, with southern states choosing different days.) After World War I, the day shifted from remembering the fallen in the Civil War to those who had perished in all of America's conflicts. It gradually became known as Memorial Day and was declared a federal holiday and moved to the last Monday in May to organize a three-day weekend beginning in 1971.

The easiest way to think of the two holidays is to consider Veterans Day a time to shake the hand of a veteran who stood up for our freedoms. Memorial Day is a time to remember and honor those who are no longer around to receive your gratitude personally.

What Is the Kitchen Like on the International Space Station?

Clayton C. Anderson:

The International Space Station (ISS) does not really have a "kitchen" as many of us here on Earth might relate to. But, there is an area called the "galley" which serves the purpose of allowing for food preparation and consumption. I believe the term "galley" comes from the military, and it was used specifically in the space shuttle program. I guess it carried over to the ISS.

The Russian segment had the ONLY galley when I flew in 2007. There was a table for three, and the galley consisted of a water system—allowing us to hydrate our food packages (as needed) with warm (tepid) or hot (extremely) water—and a food warmer. The food warmer designed by the Russians was strictly used for their cans of food (about the size of a can of cat food in America). The U.S. developed a second food warmer (shaped like a briefcase) that we could use to heat the more "flexibly packaged" foodstuffs (packets) sent from America.

Later in the ISS lifetime, a second galley area was provided in the U.S. segment. It is positioned in Node 1 (Unity) and a table is also available there for the astronauts' dining pleasures. Apparently, it was added because of the increasing crew size experienced these days (6), to have more options. During my brief visit to ISS in 2010 (12 days or so) as a Discovery crewmember, I found the mealtimes to be much more segregated than when I spent five months on board. The Russians ate in the Russian segment. The shuttle astronauts ate in the shuttle. The U.S. ISS astronauts ate in Node 1, but often at totally different times. While we did have a combined dinner in Node 1 during STS-131 (with the Expedition 23 crew), this is one of the perceived negatives of the "multiple-galley" scenario. My long duration stint on ISS was highlighted by the fact that Fyodor Yurchikhin, Oleg Kotov, and I had every single meal together. The fellowship we—or at least I—experienced during those meals is something I will never, ever forget. We laughed, we argued, we celebrated, we mourned …, all around our zero-gravity "dinner table." Awesome stuff!
