Fire extinguishers are systems that are able to put out small fires. The most popular types of such systems are AB, BC, and _____
AC
CA
ABC
All of these
The types of fires these extinguishers can put out can be AB, BC, or ABC where A is wood or paper, B is flammable liquids, and C electrically energized fires. (Isn't C flammable gases? Class E: Fires involving ELECTRICAL APPARATUS. Please correct.) ::EDIT:: These standards are NOT internationl. US Standards have C listed as electrical. Europe/Asia has class E listed as electrical. Also; I feel like I see far more AD systems than ABC systems. http://www.brkelectronics.com/faqs/oem/what-do-the-abc-ratings-mean-on-fire-extinguishers
