Answer

Brief Explanations:

  • In a fire, elevators can malfunction, trap people, and spread fire and smoke, so they are not to be used, making the first statement true.
  • The two main types of smoke detectors are ionization and photoelectric, so the option "None of the above" for the second question is incorrect.
  • The fire - triangle consists of fuel, oxygen, and ignition source, which are the three things that cause fires.

Answer:

  1. True
  2. Ionization and Photoelectric
  3. Fuel, Oxygen, Ignition
