|9 Volt Battery Safety|
|July 29, 2022|
Smoke alarms save lives. There’s no doubt about it, and this is why it’s recommended that you replace the batteries once or twice a year.
If batteries are used, stored, and disposed of correctly, they pose little risk, but while they help save lives they can also be dangerous. When they’re not given the respect they deserve, problems can arise.
Most of us have a kitchen ‘junk’ drawer. It’s the place where spare light bulbs, business cards, receipts, birthday candles, batteries, paper clips, keys, and other paraphernalia are dumped. Don’t know what to do with something? Into the junk drawer; out of sight and out of mind.
Kitchen junk drawers have been linked to serious house fires. While there could be a number of causes, one of the major dangers is from 9V batteries. You can see a 9V battery in the image: it’s the one with its terminals side-by-side. If those terminals come into contact with material that creates a circuit, the electricity generates heat with can start a fire.
Metal objects are common items in a junk drawer. Touching the battery terminals to the metal sends a current through the metal, which heats up and causes heat that may start a fire in the drawer.
Imagine you needed something from the junk drawer. You’d open the drawer, get out what you needed, and push the drawer shut. What if something came into contact with the battery terminals and created a current? There are other flammable materials in the drawer and the drawer itself is timber. You’d happily go about whatever you were doing, perhaps even go to work or to bed, completely unaware of the trouble brewing in the junk drawer.
You’d be thankful you changed the smoke alarm battery, of course, but it’s a potential risk that can be avoided. Don’t store batteries in the junk drawer.
So once you remove the old battery, how do you dispose of it?
Tossing batteries in the general rubbish bin sends them to landfill, where they become a significant fire hazard. Instead, you could:
* Place them back in the original packaging or into the packaging the new battery came from.
