Where is the emergency wall switch for the ventilation system located?

The emergency wall switch for the ventilation system is strategically located on the outside of the entry to Room 007 to ensure accessibility in case of an emergency. This placement allows individuals to quickly shut down the ventilation system without needing to enter the room, which may be necessary if there is a hazardous situation present inside, such as smoke or a gas leak.

By placing the switch outside, it enhances safety and facilitates a prompt response, ensuring that personnel can act quickly without putting themselves at risk. This location is typical in building design to prioritize safety protocols and ensure that emergency equipment is readily reachable when time is of the essence.

The other available options may not provide the same level of accessibility during emergencies. For instance, having the switch inside Room 007 could delay response time, while a roof-level switch would be impractical during emergencies. Similarly, placing it in the hallway near Room 007 might not ensure that personnel have immediate access from an external position where they could assess the situation more safely.
