In the outdoor design plan, which concept addresses unauthorized access risk?

• A. Ventilation
• B. Fire protection
• C. Intrusion (security)
• D. Egress

Answer: (C)

Unauthorized access risk is addressed by intrusion (security) measures. This concept focuses on preventing or detecting people who should not be on the site, using barriers, gates, lighting, cameras, and monitoring to secure the perimeter and control entry. In an outdoor design plan, prioritizing intrusion security helps protect people, equipment, and any flame effects from vandalism or harm, guiding decisions about fences, locks, alarms, and surveillance.

Ventilation concerns air movement and hazardous buildup, fire protection focuses on reducing fire risk and enabling suppression, and egress deals with safe exit routes during emergencies. None of those specifically targets preventing unauthorized entry like intrusion (security) does.
