I get my system inspected and approve by a certified inspector once a year.
All I want/need is a fire blanket for the galley area. Yes, I do have an over sized fire extinguisher in each of the compartments and 2 at the helm.

Element appears to be an Italian version of STAT-X. This enclosed space aerosol type fire extinguishing using radicals to interrupt burning has been around for at least 5 years that I am aware of and longer considering other fire extinguishing agents have the same claims.. It is on the periphery of fire protection and does not have enough merit to take off. Kind of like nitrogen in you tires. It has enough science but not enough advantage to become mainstream. Experiment if you want but do not rely on product that are not U.L. Listed or USCG approved.

Halon is toxic but not so much in the 5 to 10% range used in fire extinguishing.

Cleaning up after a fire extinguisher goes off is a chore. A fire blanket over a pot is a “my bad” and a chuckle.
NFPA 1 removed the "rap shake and turn over" fire extinguishers requirement many years ago...

Thats what I thought too because of the anti-caking additives....almost posted it an hour ago but......

......a quick search still showed the vast majority of organizations out there still suggesting it...unless I kept mining old info.

Thanks guys. Good to know. Now that I have the habit don’t see any harm to it. Is there good evidence the anti caking works?

Hard to tell how little motion is needed to keep the powder loose.

Most (older) extinguishers used in training sessions seem to work fine, but no telling what they have undergone before use.

An annual beat down or shake is so easy, hard to break the habit, and as I posted...lots of web advice to keep doing it.

In a crisis it would be easy to confuse with flares
