Schools must conduct at least one safety-related drill per month.  The drills must teach students basic responses for shelter-in-place, lockdown, and evacuation, terms defined as follows:

• "shelter-in-place" is used to limit the exposure of students and staff to hazardous materials, such as chemical, biological, or radiological contaminants, released into the environment by isolating the inside environment from the outside.
• "lockdown" is used to isolate students and staff from threats of violence, such as suspicious trespassers or armed intruders, that may occur in a school or in the vicinity of a school.
• "evacuation" is used to move students and staff away from threats, such as fires, oil train spills, lahars, or tsunamis.

The drills must also incorporate an earthquake drill.  Schools in mapped lahars or tsunami hazard zones must include a pedestrian evacuation drill.

School lockdown drills may not include live simulations or reenactments of active shooter scenarios that are not trauma-informed and age and developmentally appropriate.
