Fire engineering is the application of science and engineering principles to protect people, property, and the environment from the harmful effects of fires. Fire engineers use their expertise in areas such as building design, fire dynamics, and human behavior to develop strategies for fire prevention, detection, and suppression. They work to ensure that buildings and other structures are designed and constructed in a way that minimizes the risk of fire, and that occupants have the knowledge and resources to safely evacuate in the event of a fire. In addition to designing and testing fire protection systems, fire engineers may also be involved in the investigation of fires to determine their causes and identify ways to prevent similar fires in the future.
