70% to passWhen combating a class C fire, which of the following dangers may be present?
AFlooding of the vessel
BWater damage to machinery not involved in the fire
CToxic fumes from burning insulation or electric shock
DIncreased surface area of the burning fluid
AI Explanation
The correct answer is C) Toxic fumes from burning insulation or electric shock. When combating a Class C fire, which involves energized electrical equipment, the main danger is the presence of toxic fumes from burning insulation or the risk of electric shock. The burning of electrical components and insulation can release hazardous fumes, while the energized equipment poses an electrocution hazard. The other options, such as flooding the vessel (A) or water damage to unrelated machinery (B), are not the primary dangers in a Class C fire. Additionally, increased surface area of the burning fluid (D) is a concern for Class B fires, not Class C fires involving electrical equipment.
