After a little more reading, I've learned that many budget Li-Ion chargers (including apparently the TR001) actually go into a trickle-charging mode after the battery is charged and the green light comes on. This is unfortunate, as trickle-charging Li-Ions is not exactly safe. They will continue to accept charge as long as current is applied, and this can lead to overcharging. Overcharging Li-Ion batts is quite likely to eventually cause them to explode. Thus, it is extremely important that batteries themselves include overcharge protection. Problem is, even if they do have such protection, the circuit can fail. With a better-quality charger (charging overcharge-protected batts) that switches itself off after the batt is finished charging, the benefits are obvious...there is double protection...one picks up the slack if the other fails. The question does arise: why do cheap Li-Ion chargers trickle charge, then? I don't have an answer, but wouldn't rule out the possibility that it's just a crappy or flat-out faulty design which continues to be produced simply because it's cheap to do so. In any case, before I buy any other vaping gear I'll be snagging a better charger. In the meantime, will definitely watching for the TR001 green light like a hawk.
I'm not suggesting that this is what caused the OP's boss' incident, though of course it could be...just passing along what I've learned in the course of trying to find out what might have happened.

Batteries can explode when you charge them. It's pretty rare but you should always charge them in a fireproof battery charging bag like this one: HobbyKing R/C Hobby Store : Lithium Polymer Charge Pack 18x22cm Sack
It's just a few bucks. I mean what's the risk here? Getting killed? Losing everything? People pay more money for fire insurance and smoke detector batteries. I also recommend you get yourself a metal box to put this bag in and charge them like that. That way even if they go off like a bottle rocket you're good to go. You only lose the battery.
As more people vape you will have more explosions, AW's are not safe they are safer.

Exactly. AW batteries go up too. (reference candelpowerforums). The more we keep pushing the envelope on these things the greater the odds.

I think some of the problem here is people are using things they don't know safely how to use. (the batteries) I feel sorry for the OP and I'd hate to be in that situation. Veterans on this forum continue to recommend "huge" PVs to newbies and people take that to heart. Some don't ever read the battery threads, some are clueless to the proper handling technique of the batteries. I fully endorse whatever works for someone but I guess some people use these things are just lucky that they've not had things go wrong and get injured.
Please keep us posted as to what if anything you are able to find out. I'm glad your boss is ok.
I concur with your post but do take exception to veterans recommending "huge" PVs. I will not deny that some do, but that is not the norm. A lot of the misinformation on this forum stems from newbies educating newbies. How long have I been preaching not to use LRs on eGo batts, yet now folks are using DCs
I went with the PILA charger. it was more expensive but from the reading i did i figured it was better than the cheapest out there.
and was not as expensive as some of the hobby chargers i was pointed too at the time. so far so good.
I use AW IMR 16340's
I never leave bats in charger once they are charged.
I never leave them unattended while charging.
I transport my bats in a Plastic case made for that purpose.
I do aggree that we need to keep up with these incidents so we can learn from them.
Oh and Deach love that tower pic, you a Ham Radio Operator too?
