The extinguisher will eventually run out of pressure, preventing an explosion. Safety valves, or ruptured discs, are included with nearly all tanks that hold pressure. If a fire extinguisher gets under extreme heat, it may only melt …
A shop-vacuum can be used to clean up fire extinguisher residue outdoors, but it is better to use a special HEPA vacuum for indoor clean up that will not disperse the chemicals and the dust into the air. Do not add water to chemical water extinguisher discharge. Water can make the powder pasty, more corrosive, and harder to clean.

What happens if you recharge a fire extinguisher?
Re-charging a fire extinguisher could result in overcharging. This could make it more susceptible to bursting or failing when dropped. Extreme events could put abnormal pressure on the extinguisher beyond factory limits. Always follow the guidelines on the extinguisher as to what amount of recharging is necessary.
