OSH Security Practice Test

What is a common physical access control method employed in a building?

1. Doors and mechanical locks.

2. A gate, barricade or a fence.

3. A guard dog.

4. An alarm system.

The correct answer is: Doors and mechanical locks.

Doors and mechanical locks are a fundamental physical access control method used in buildings. They serve as the first line of defense, regulating who can enter or exit a facility. By using locks, organizations can manage access to sensitive areas, ensuring that only authorized personnel can gain entry. This method is easily implemented, cost-effective, and provides a visible deterrent to unauthorized individuals. While options like gates, barricades, or fences also provide a physical barrier, they are more oriented toward preventing access from the outside rather than controlling entry into specific areas within a building. Guard dogs may add an extra layer of security, but they are not as universally employed or reliable for day-to-day access control. Alarm systems are essential for security monitoring and alerting to breaches but do not physically prevent access. Consequently, doors and mechanical locks are the most direct and common method for controlling physical access in a building context.
