OSH Security Practice Test

What is a common form of physical access control?

1. Lock and key

2. Parameter control

3. Field alarm

4. Slide card

The correct answer is: Lock and key

A lock and key is a fundamental and widely recognized form of physical access control. It serves as a barrier to entry for unauthorized individuals while allowing access to those who possess the appropriate key. This method has been utilized for centuries and is a straightforward solution to restrict entry to secure areas, such as offices, safes, or storage facilities. The other options do not represent common forms of physical access control in the same way. Parameter control generally refers to managing and regulating the parameters of a system rather than physical access. A field alarm may be used for alerting about security breaches but does not actually prevent physical access itself. Slide cards, while they can be used for access control, are less traditional than the simplicity and reliability of a lock and key, making the latter a more universally accepted method of physical security.
