Alberta Basic Security Training (ABST) Practice Exam 2025

Question: 1 / 400

What can be used to determine changes in temperature, such as fire behind a door?

Pressure sensors

Infrared cameras

The correct response is the use of infrared cameras to determine changes in temperature, such as detecting a fire behind a door. Infrared cameras are specialized devices that detect heat emitted from objects. They convert thermal energy into visible images, allowing individuals to see temperature variations even in complete darkness or obscured environments. This technology is particularly valuable in situations like assessing fire hazards, as it can highlight areas of high temperature without direct contact.

Infrared cameras enable security personnel, firefighters, and first responders to identify potential fire sources, locate trapped individuals, or monitor hazardous conditions, enhancing safety and effectiveness during operations. Other methods, while they may provide some information, do not offer the same level of accuracy or safety in assessing temperature changes.
