When a motor on operation catches fire, ( ) should be used to extinguish the fire. A. Foam B. Dry sand C. Water D. Sprinkler gun. Some beachgoers have already noticed that there is an issue with this question, but only some of them. Why didn’t everyone notice this problem? There are four options, and none of them is completely correct. (Comparatively, I gave B, but this isn’t the best answer; it’s just better than the other three options.) I suggest everyone think about what to do if a motor in operation catches fire
B, D, right? Why is there no carbon dioxide? It’s a dry powder fire extinguisher

When a motor on operation catches fire, a (carbon dioxide) fire extinguisher should be used. ——I didn’t know that dry sand could be used to extinguish fires in electrical appliances. 20. A thermocouple is a component used to measure the (temperature) parameter.

Here, for 19, one can only choose (dry sand); there are better options such as carbon dioxide, dry powder, and (1211, which is no longer in production). For 20, there’s no doubt – choose (temperature)

19. When a motor on operation catches fire, (D) should be used to extinguish it. A. Foam B. Dry sand C. Water D. Spray gun. A spray gun can be used to extinguish fires involving solids, liquids, and electrically charged materials. 20. A thermocouple is a component used to measure (D) parameters. A. Level B. Flow rate C. Pressure D. Temperature
