Which of the following is true of an emergency generator installation?
The generator should be operated in a well-ventilated area✓پاسخ درست
The generator must be insulated from ground
Fuel should be stored near the generator for rapid refueling in case of an emergency
All these choices are correct
توضیح
An internal combustion generator produces carbon monoxide, which is colourless and odourless and accumulates rapidly in an enclosed space, so ventilation is the controlling requirement. Insulating the generator from ground removes protection rather than adding it, and storing fuel next to a hot running engine adds a fire hazard.
