Hazardous Material / Chemical / Siren Shelter
Immediate safety precautions
☐ Go indoors immediately and move to interior rooms.
☐ Close exterior doors/windows and shut down outside-air intake if trained/authorized.
☐ Keep people away from affected air, spill, vapor, or suspicious substance.
☐ Monitor City of Tulsa, Tulsa County EM, NWS, and official instructions.
☐ Prepare for evacuation if officials change direction.
Avoid these common mistakes
☐ Do not go outside to look.
☐ Do not touch, smell, or clean unknown substances without direction.
☐ Do not self-deploy into a contaminated area.
School / child-release decision checkpoints
☐ Account for all students, staff, visitors, and groups before release or relocation.
☐ Confirm official all-clear or emergency-management direction; do not rely on sirens alone.
☐ Inspect route, shelter, assembly, and pickup areas for fire, flood, utility, debris, traffic, or security hazards.
☐ Use controlled reunification for parent pickup: ID verification, release log, traffic control, and one official communication channel.
