Any idea why?

[Hudds Lad]

Was checking the fire extinguishers yesterday, and this one in the engine room has magnets stuck on it, any good reason why?

 

Also, how old is too old? All three are in pressure according to the gauge, but two are 2007 vintage and the one with magnets 2006. BSS blurb doesn’t seem to mention any age limit that I can see.

Give 'em a shake now and again and they are fine.

Just a handy place to store magnets which "like" to be stuck on something known as a keep to stop them loosing their power.

?

A long as they are in good condition, appropriately marked, and don’t have a marked expiry date, they’re fine. Looks the same as one of mine (sans magnets).

The magnets would be better employed stuck on your oil filter can.  They are doing nothing on a fire extinguisher.

Needle in the green?  Just give them a good shaking every month or so.

The magnets could be used to stick the extinguisher to an engine room bulkhead perhaps instead of using the holder. Can't think of any other reason.

Good place to keep magnets, you obviously remember where they are.  I keep a couple of magnets on the end of my too box, but I shall move them to a fire extinguisher as it’s a good idea.

The puzzling thing is the magnets appear to be curved to fit the shape of the fire extinguisher cylinder. Being probably less than 4" in diameter I'd say a flat magnet simply would not stick on all over like those in the photo.

 

Therefore, they must be either specially made curved to mate cosily with the fire extinguisher body and so present for specific reason, or they are made from that magnetised rubber that vehicle signs are made from.

Magnets lose their magnetism and die when they exceed their Curie temperature. These magnets have obviously decided that their best chance of surviving a boat fire is to be attached to an extinguisher! 😀

Out of a dead starter or some other motor I would guess.

As they’re not doing any harm or getting in the way i guess i’ll just leave them there. Just wanted to check they didn’t serve some arcane purpose as a quick internet search yielded no useful results.

Picking up dropped pins and screws but not much good in a steel bilge. Also, for taping to a length of wood to retrieve tools from tight spaces.

 

I used one to secure spare keys in a well hidden and difficult to get at location, having gone to the boat once and found I had left the keys at home.

Shurflo pump motor magnets.

Can't you put a bit more information in your thread title?  I hate it when people do this. I've a busy enough life as it is without wasting my precious time having to open a thread to see what it's about, only to then find out I'm not interested in its subject. 😉😀

Seeing as it’s you and you’ve asked so nicely, no 😛 

 

It can’t be edited now i’m afraid, i’ll claim in my defence that i’ve been reading too many online news headlines recently and have become subconsciously infected with clickbaititis. I’d tell you more but you’d not believe what happened next!

Has anyone ever managed to re-fit these magnets to a Shurflo and get it running? They seem to have been glued in  with the glue having a finite life. The magnets being magnetic(!)  don't want to go where they need to.

[bizzard]

Yes I've stuck em back in with Araldite after a pump was submerged for a long time, they'd come adrift and were clinging to the armature. It worked for a few years after.

Lol, as the most interesting bits of the forum are often to be found after the first few responses, I don't think it matters, but I suppose the OP could have titled it, " why has someone stuck magnets on my fire extinguisher?"

However we have now discovered they should be shaken frequently and something about Shureflo pumps, so I think we are better off than we were before.
