Same way a .50 cal rifle like the Barret M122 loaded with EX-Explosive rounds doesn't blow up your head when it misfires; damage abstraction.
If y'all play with location specific wound rules like those in earlier editions that's fine, but don't assume everyone who comes to these boards do...
A misfire in a weapon means the round didn't go off. Generally clearing the breech the solves the issue and you are good to go. The gun doesn't blow up because the stress of the round doesn't exceed the strength of the breech.
ELECTRICITY DOES NOT EXPLODE!!!!!!
Electricity is the flow of electrons. Pure and simple. It flows from a More positively charged environment to a less charged environment at the molecular level. This Flowing of electrons is impeded by the material that they flow through, and this resistance has the noticeable effect of generating heat. The larger the flow of electrons (volts) and with larger force (amps) results in larger amounts of heat.
WHAT DOES EXPLODE WHEN ELECTRICY IS APPLIED?
With enough flow and enough force, EVERY thing explodes. Meaning, everything is pushed away from the flow of electrons thanks to both the magnetic forces involved and simple physics. What you are "seeing" in an electrical explosion is the matter of the object being pushed away from the electricity... in other words, that was the glove, and your hand, and the coat of the person your touched, and parts of their flesh and bone that exploded away from the flow of electrons. Not the electrons themselves exploding.
