When the floor area is sprinkled, which of the following is not an acceptable way of venting smoke?

1. Mechanical ventilation system

2. Natural ventilation via open windows

3. Louvre systems

4. Fixed glass windows

The correct answer is: Fixed glass windows

Fixed glass windows are not an acceptable way of venting smoke when the floor area is sprinkled because they are not adjustable and can potentially trap smoke inside the building. Mechanical ventilation systems, natural ventilation via open windows, and louvre systems are all acceptable methods of venting smoke because they allow for the controlled release of smoke from the building. Therefore, D is the incorrect option which is not an acceptable way of venting smoke.
