Putting a screw into a lithium battery is one of the best ways to make it ignite.Agreed - the tabs struck me as not the best idea. Too bad they didn't, as an example, a cloth tab.
If a battery does get stuck from swelling, all I can think of is to run a small screw into slot of the tab and pull on the screw. Since a swollen battery is automatically no longer safe to use (*), I'm not too worried about the screw making a mess of things.
The advice for lithium battery fires is normally to use water since it is the most effective way of removing the heat and preventing the fire from spreading, CO2 doesn't help much since the battery doesn't need external oxygen to burn and non of the gas extinguishers absorb much heat. The only exception would be for high voltage lithium batteries due to the risk of electrocution, not a problem for cameras.
DO NOT POUR WATER ON A LITHIUM BATTERY FIRE!
While the battery is exploding, the fire is hot enough to disassociate the oxygen and hydrogen in water (water = H2O) which will make things exponentially worse. If the explosions are over, Halon or CO2, powder, or water can be used to put out the associated fire. If you think a battery might go, unless you have a Halon or CO2 extinguisher, let it go. BTW, Halon, being a fluorocarbon, can release fluorine gas when used in a very hot fire - fluorine gas is bad for all living things, including you.
Have a nice day.
Note that there is not much lithium in the battery that can be burned so it is not the same as a BMW engine fire where the best approach is to run since it is impossible to extinguish!
I've been carrying the Gitup F1 today in the cold winter weather, makes a lovely warm hand warmer when turned on! Never gets anywhere near hot despite using the same processor and not having a metal case to keep it cool.
