What is a primary use for thermal imaging cameras in facility management?

Thermal imaging cameras are primarily used in facility management to identify hot spots and inefficiencies in electrical and mechanical systems. This technology works by detecting infrared radiation emitted from objects, allowing facility managers to visualize temperature differences. By pinpointing areas that are excessively hot, managers can uncover potential issues such as overloaded circuits, failing components, or insulation problems. Addressing these inefficiencies helps prevent equipment failure, reduces energy consumption, and enhances overall system reliability.

The other choices, while relevant to facility management, do not align as directly with the primary functionality of thermal imaging. Documenting employee safety procedures does not involve thermal imaging technology; monitoring energy usage typically requires different tools and meters; and assessing air quality in HVAC systems usually relies on different technologies like air quality monitors rather than thermal imaging.
