The video below says it all, and from someone who is an experienced veteran in this hobby...

I second the "connected" warning. I had similar incident where my charger was in standby with the battery still connected from the night before. I was outside and heard something beeping inside the house. I came in to discover that the beeping was the smoke detector. The house was filling with smoke. I discovered the shelving unit that had the charger on it was in flames. The LiPo had rocket-propelled itself and the charger onto the floor where it burned a hole in the floor and also set the base of the shelving unit on fire. If I had not been home to extinguish the flames, or had not heard the smoke alarm as soon as I did, the house would have burned to the ground.

I've always charged in a metal drawer, but sometimes I wonder if I should just clean up the old wood stove in my place and charge them in there.

I think this is the point that drives it home. If this happened to any noob like myself people would most probably just think "just another noob that didn't know what he was doing".

Also note.. it’s not just larger lipos.. small 1s batteries can light off and may not seem like Much “energy”.. if it’s near a source of “fuel”..
If u charge in doors (unattended) I do it in my fireplace in a ammo can..the can keeps my dogs from being “curious”.. yes, I did have a incident.. a single 1s melted through a dog bed.. better the bed then my dog..

JB made a good suggestion on yesterday's live stream. If you charge indoors, have a pair of thick leather gloves nearby so if something does go wrong you can pick up the LiPo and lob it out the window without burning yourself, unlike Pawel who unfortunately sustained some minor skin burns trying to do the same without gloves. I own some MIG welding gear so I think I will go and look out the welding gloves and keep them stored in the work area where I charge my LiPos.

i never had anything scary on a lipo until last month. i had a shocking experience on a lipo while charging.
i came out of my toilett, walked next to my charging station, looked short and was close to walk away. the lipo looked a little bit fat, i looked again and checked its temperature. it wasnt hot hot, but there was some heat and the increased size.
i believe there was a risk for a fire if i didnt came across to the charhingstation.

i beleive one of my isdt chargeres would ring and stop their work more early, i sorted out my old horizon dynamite charger: the word dynamit didnt gave me a save feeling seems i have it xD

sort out dangerous stuff, dont mention loosing money on chargers, they are important about battery health / savety and also about power, lipo performance :-)

Short of that, or a Bat-Safe, you can always use a 12” clay pot filled about halfway with sand and covered with a ceramic tile as a lid. It will, in most cases, control the fire while allowing gasses and smoke to exhaust without creating a bomb.

When i started with FPV i was lucky/unlucky enough to see all the scary lipo fires, so now i have 3 expensive but worth it Bat Cases for my lipos. Also looooong before my FPV hobby i once tried to build a big lipo pack for my professional underwater 25kg video housing / lights kit. After i build it it caught fire and almost burned my house down. I managed to throw the burning thing on the balcony where it kept burning for at least 30 minutes. Then it stopped, flared up a few hours later again with a small bang . I left it there for a few days before i dared to touch it.
Since then i am a pussy with lipos.
