Fire safety

Fire safety is a new domain emerged in the early 90s to enable the design of buildings, structures, and infrastructure against destruction through fire. It also includes the provisions of building codes. This field is mostly associated with the design and efficient planning of a building, to reduce the destruction caused by fire. The branch of engineering that deals with it for the safety of the buildings from destruction of fire, is known as fire safety engineering.

Partial Question 9 Which choices are correct explanations about the scanning electron microscope (SEM)? (Select all that apply.) Visible light is the main light source. The microscope can investigate non conductive samples as good as the conductive ones. Samples need to be polished. The condensed beam does not pass through the specimen, but is reflected from a surface of the specimen and was collected to obtain the picture. Useful resolution range is much wider than the optical microscopes.
