What is the purpose of a fire tetrahedron in fire science?
A. To represent the four stages of fire development
B. To illustrate the four elements required for combustion
C. To classify different types of fires
D. To identify the sources of ignition
Which type of fire detector is most effective for detecting smoldering fires?
A. Heat detector
Answer (2)
Creating firebreaks is the most effective strategy for controlling wildfires, while the incident commander's role is to coordinate operations. Thermal barriers delay heat transfer in fire-resistant construction, and Halon is commonly used in clean agent fire suppression systems. The fire tetrahedron illustrates the essential elements needed for combustion.
