🔍 Key Concepts
• Fire classes (A, B, C, D, K) and what type of fuel each class involves
• Difference between ordinary combustibles, flammable liquids, electrical fires, and metal fires
• How energized electrical equipment is treated in fire classification
đź’ Think About
• First, recall what each fire class (A, B, C, D) represents in general terms, then match the options to those definitions.
• Ask yourself: which of the choices would be specifically associated with an electrical source versus a material that simply burns on its own?
• Consider which class is used when the primary hazard is shock/electrocution rather than just the burning material.
âś… Before You Answer
• Be sure you know that Class A is for ordinary combustibles like wood, paper, cloth.
• Confirm what Class B and Class C each represent before matching to the answer choices.
• Check which option would be present only when equipment is energized (powered) rather than just a material sitting by itself.
