Which of the following procedures is NOT included in the four life safety procedures?

The four life safety procedures typically focus on immediate responses to threats that may endanger lives, such as evacuation, sheltering, and lockdown. Each of these procedures is crucial for ensuring safety during emergencies. Evacuation involves a planned and controlled process whereby individuals exit a building or area to avoid danger. Sheltering refers to taking refuge in a specific area to protect individuals from an external threat, such as severe weather or a hostile intruder. Lockdown procedures are designed to secure individuals within a facility, preventing entry from external threats.

Training, while essential for preparing individuals for emergencies and ensuring they know how to respond correctly in situations involving the other life safety procedures, is not classified as a direct life safety procedure. Instead, training serves as a supportive measure to empower individuals to execute life safety procedures effectively when the need arises. Hence, it does not fit within the operational categories of evacuation, sheltering, or lockdown.
