I am just going to copy/paste directly from The Silicon Graybeard:

I’m not sure everyone has heard about the massive Kidde fire extinguisher recall, but Kidde is the giant in the field and more than 40 million fire extinguishers are affected.  There are two lines of fire extinguishers affected: plastic-handled, and push button.

The US Consumer Product Safety Commission announced the recall of more than 40 million Kidde disposable fire extinguishers Thursday, saying they may malfunction during an emergency.

The faulty extinguishers are equipped with plastic handles and push-buttons and can become clogged. Their nozzles also may detach with enough force “to pose an impact hazard,” the CPSC said.

The recall covers 134 models of Kidde plastic-handle fire extinguishers manufactured between 1973 and August 15, 2017, including models that were recalled in 2009 and 2015. It also includes eight push-button models manufactured between 1995 and September 22, 2017.

The company has set up a web page with a couple of pages to help you determine if your fire extinguishers are included – Kidde labels their products for dozens of companies.  We just spent the evening inspecting the four we have in various places around the house, and all but one are affected.

Replacements can be applied for online.

If Kidde determines that you have an affected model, the company says it will send you a replacement within 10 to 15 business days. The new extinguishers contain metal parts instead of plastic.

I just checked the two we have and both are on the list. The push-button type is already reported, but the plastic handle page is not processing, so I’ll keep at it till it croaks or somebody fixes it.

This is not something to disregard, check your extinguishers ASAP.
