Explain how a mantrap works.

A common enhancement for locks in high security areas is the mantrap. A mantrap is a small enclosure that has separate entry and exit points. To gain access to the facility, area, or room, a person enters the mantrap, requests access via some form of electronic or biometric lock and key, and if confirmed, exits the mantrap into the facility. Otherwise the cannot leave the mantrap until a security official overrides the enclosure's automatic locks.

Identify the "Seven Major Sources of Physical Loss"?

ANS: 1. Extreme temperature: heat, cold 2. Gases: war gases, commercial vapors, humid or dry air, suspended particles 3. Liquids: water, chemicals 4.

Describe different types of sensors to detect intrusions.

There are a number of different types of sensors: motion detectors, thermal detectors, glass breakage detectors, weight sensors, and contact sensors. Motion detectors detect movement within a confined space and are either active or passive. Thermal detectors work by detecting rates of change in the ambient temperature in the room. Contact and weight sensors work when two contacts are connected as, for example, when a foot steps on a pressure-sensitive pad under a rug, or a window being opened triggers a pin and spring sensor. Vibration sensors also fall into this category, except that they detect movement of the sensor rather than movement in the environment.
