Safety protection means making preparations and protection to deal with attacks or avoid being victimized, so that the protected object is in a safe state without danger, being invaded, or having accidents. In construction engineering, due to the large amount of labor, large-scale projects, a large number of miscellaneous laborers, and the weak safety awareness of laborers, safety accidents occur frequently. Therefore, safety is particularly emphasized in construction engineering.
