This may be old news to some but Kidde is recalling nearly 40 million fire extinguishers . They may not discharge when needed and may even explode !
The extinguishers affected were manufactured with plastic handles or push buttons , and are primarily used in autos , boats , and RV's . Go to the Kidde website to see if you have an affected extinguisher . If you do it will be replaced free , you don't have to return the old one .
It's worth checking . I had two that will be replaced , one of them is nearly 15 years old !
