Buildings under construction or demolition can present which of the following in comparison to a completed building?

Buildings under construction or demolition typically present extra hazards beyond those found in completed structures. This scenario often involves numerous risks, such as unstable structures, the presence of heavy machinery, incomplete wiring, and exposed building materials. During construction, the environment can change rapidly, which increases the likelihood of accidents or injuries due to falls, equipment failure, or collapsing materials.

In addition, both construction and demolition activities can introduce airborne contaminants, such as dust, and increase the risk of fire due to the presence of flammable materials. The lack of completed safety features, such as fire protection systems or hardened structural elements, enhances the dangers associated with these sites.

Understanding that these buildings have more hazards is crucial for firefighters and safety personnel, as it directly influences safety protocols, emergency response strategies, and risk assessments during operations in such environments.
