Why should we avoid running the vehicle’s engine in a closed placed?
- Correct answer: Because the emitted burnt gases (exhaust)are toxic.
- To avoid engine over-heating due to poor ventilation.
- There is no need to avoid it, because it is not important whether or not the engine is running in a closed or open place.
- Because the engine cannot be operated in a closed place.
Why this is the answer
The correct answer in the official bank: Because the emitted burnt gases (exhaust)are toxic.
Exhaust gases contain carbon monoxide, a toxic gas with no colour or smell. In a closed space such as a garage, it builds up quickly and can cause fainting or even death. So never leave an engine running in an enclosed area, and if you must, ensure good ventilation. The engine can run there and won't overheat for that reason; the danger is to people.
