I live in a 600 sqft studio apartment it is already equipped with sprinklers.<br><br>I have nothing unusual in the apt other than ammunition and cleaning chemicals. I have a Kidde ABC rated fire extingusher (whatever that means) but it's 6 years old, the safety ring is broken and I haven't used it but the meter says it's still fully charged.<br><br>I want to get another one just in case. What should I look for in a good home-use fire extinguisher?<br><br>And is one necessary for the car if I am not a race car driver?
