Question

select the choice that best completes the following statement. class c fires cannot be extinguished with: a) dry chemical b) water c) carbon - dioxide d) foam

Explanation:

Class C fires involve energized electrical equipment. Water is a conductor of electricity. Using water on Class C fires can cause electric shock and spread the fire due to its conductivity. Dry chemical, carbon - dioxide, and foam (specific types like CO₂ - based foam for some electrical applications in non - conductive forms) can be used as they do not conduct electricity.

Answer:

B. Water
