Identify three typical fire protection measures in interior spaces.

• A. Acoustic panels, decorative lighting, area rugs
• B. Elevators, escalators, stairs
• C. Smoke detectors, fire alarms, portable extinguishers
• D. Security cameras, motion sensors, bollards

Answer: (C)

The concept being tested is identifying practical fire protection measures inside a space that address detection, warning, and initial suppression of a fire. The trio of smoke detectors, fire alarms, and portable extinguishers fits this role best. Smoke detectors continuously monitor for smoke and will trigger a warning if a fire is starting, giving occupants time to react. Fire alarms then cascade that warning throughout the space, coordinating a safe evacuation and prompting building systems to respond. Portable extinguishers provide a means for occupants to attempt to control small fires early, potentially preventing spread while everyone evacuates or waits for responders. Together, these elements cover the essential stages of interior fire safety: detect, alert, and respond.

Options that include interior finishes or aesthetics don’t serve fire protection functions. Elevators, escalators, and stairs are about egress routes, not active protection. Security cameras and bollards relate to security rather than fire safety.
