What type of fire extinguisher should a tram be equipped with?
Show the correct answer
Correct answer
C. CO2 fire extinguisher
Explanation
The question is about the type of fire extinguisher that a tram should be equipped with. A tram should have a carbon dioxide or powder fire extinguisher - answer C.
The rules on tram equipment require a carbon dioxide fire extinguisher with 5 kg of carbon dioxide or a powder fire extinguisher with 6 kg of powder for class ABC fires. A tram is powered by electricity from the overhead contact line, and a fire most often starts in the electrical equipment. Both of these types of fire extinguisher are suitable for putting out fires in live electrical equipment. A water fire extinguisher (answer B) and an ordinary foam one (answer A) conduct electricity, so using them on live equipment creates a risk of electric shock. The tram driver should know where the fire extinguisher is in the tram and should check before leaving that it is in place and has a valid inspection.
