What must the last OT departing the room ensure is turned off?

The correct answer highlights the importance of ensuring that all lights and equipment are turned off when the last officer leaves a room. This practice aligns with safety protocols and environmental considerations. Turning off lights not only conserves energy, which is essential for sustainability, but also reduces the risk of electrical malfunctions or fire hazards that can occur with unattended equipment. Ensuring that all equipment, such as projectors or other electronic devices, are deactivated prevents unnecessary power consumption and extends the lifespan of the devices.

In contrast, while computers and pens or markers and chairs may be important to manage, they do not encompass the broader safety and energy-saving objectives as effectively as ensuring lights and equipment are off. Leaving essential electronic devices on can lead to both safety issues and increased energy costs, underscoring the necessity of this protocol in a shared environment.
