When a shelter-in-place instruction is active, start by asking, “What does the current instruction say?” Staying in an appropriate indoor space may be safer than traveling, but the order for the current hazard controls the decision. Leave only for a genuinely time-critical need or when an authority directs or requires travel. Check the instruction, test whether the need can wait, tell someone your plan, and follow the hazard-specific exposure guidance. A shelter-in-place order and an evacuation order are different. One may direct you to remain inside; the other may direct you to leave. If officials issue an evacuation, fire, road-closure, public-health, or other direct instruction, follow it even when a general household plan points another way.
Start with the current instruction
An emergency can produce several messages at once. Police, fire, emergency management, public health, a utility, or another authority may issue the direction that applies to your location and hazard. Read the complete current message, including the affected area, action, destination or route, and update time. If the message says to shelter in place, do not treat a familiar errand as permission to travel. If it says to evacuate or relocate, staying home may no longer be the supported choice.
In a chemical emergency, the CDC directs people to listen to police, fire, and other local officials for whether to shelter in place or evacuate. Its shelter-in-place guidance may include moving indoors and following instructions for the specific event. Read CDC guidance for sheltering in place during a chemical emergency alongside the message from the authority responsible for your area.
The same principle applies to a storm, wildfire smoke, flood, biological hazard, utility failure, or civil emergency. General preparation can help you act, but it does not replace an active order. Keep the message available in the format your household can use, and continue listening for an update.
Use a short necessity test
Before reaching for keys, ask what will happen if the trip waits. A trip may need immediate action when it involves a threat to life, emergency medical care, a time-critical medication or medical-device need, an official evacuation or relocation, or a destination specifically identified by authorities. The exact answer depends on the hazard, the instruction, and the people involved.
Routine shopping, a normal school or work pickup, sightseeing, and going out to inspect damage can usually wait when the current instruction says to remain inside. “Usually” matters here. A person who needs urgent care, a household member whose medical equipment requires attention, or an animal in immediate danger may need a different response. Ask the responsible authority or emergency service for help when the situation is unclear rather than turning a convenience trip into an exposure risk.
Keep this small decision card near the household contact information:
Pause or go
>
1. What does the current official instruction require? 2. Is the need time-critical, or can it wait while you monitor updates? 3. If travel is authorized or required, what destination, route, timing, and exposure controls apply? 4. Who knows the plan, and what tells you to wait, call for help, or return?
This card does not replace local emergency instructions. It gives the household a calm order for considering them.
When waiting is the safer choice
If the need is not time-critical and no authority has directed travel, pause the trip. Keep doors and windows closed when the current hazard guidance calls for that action, stay in the appropriate indoor space, and monitor the official channel named in the instruction. Do not leave because a message has gone quiet. Wait for an update or an all-clear from the responsible authority.
A pause also protects the people who might otherwise be sent out to investigate. Looking at a damaged roof, checking a closed road, meeting someone at a familiar landmark, or buying an item that can wait may expose the household to smoke, contaminated air, floodwater, debris, traffic hazards, or an unsafe building. If someone outside needs information, use the household communication plan while officials direct people to stay put.
If the building itself becomes unsafe, the situation changes. Fire, rising water, suspected gas, dangerous heat or cold, severe symptoms, a person who cannot remain safe indoors, or another immediate life threat calls for emergency assistance and the current direction from the appropriate authority. A shelter-in-place label does not require you to ignore an immediate danger inside the home.
If travel is authorized or required
Confirm four details before leaving: destination, route, timing, and the authority that permits or requires the trip. A familiar clinic, store, school, road, or shelter may be closed, full, damaged, or inside the affected area. Use the responsible authority's current route and destination information. If transportation is a barrier, ask about an accessible ride, a designated pickup location, or other assistance before sending someone out alone.
The CDC evacuation guidance also directs separated household members to use their communication plan until police, fire, or other local officials say travel is safe. Keep that boundary in place even when someone outside the home is asking for an immediate visit.
Tell a household contact where you are going, who is traveling, what route or transportation you expect to use, and when you will communicate again. A paper card helps when a phone is lost, uncharged, or being used for alerts. The household contact sheet can hold the people and numbers your household actually uses. Keep private medical, access, and identification details protected rather than posting them in a public message.
Carry what the exact trip requires. That may include identification, medications, a required medical or mobility device, a charged communication device, a charger, water, and supplies for a service animal or pet. Do not assume a general kit covers every person or destination. Check the instructions for the device, medication, animal, or official facility involved.
For paper directions, a route card, a light, and a backup way to communicate, see the household offline route kit. Those items support an authorized trip; they do not make a closed road or restricted area acceptable.
Keep exposure controls beside the route
The hazard changes what a safe response can involve. Follow the specific instructions issued for the current event, including whether to close openings, use a designated protective measure, avoid an area, or wait for assistance. Do not improvise a chemical, smoke, flood, or biological exposure procedure from a general household checklist.
For a chemical exposure, the CDC's chemical emergency response guidance says to get away, get the chemical off, and get help. That broad sequence still requires the event's specific instructions and medical or emergency support when needed. If you have symptoms, suspected poisoning, trouble breathing, a serious injury, or another urgent condition, call 911 or your local emergency number. A website contact form is not an emergency service.
Never enter floodwater to reach a destination or shorten a route. Do not drive or walk through smoke, fire, a damaged building, an area with a downed electrical line, or a place officials have restricted. Turn around and ask the responsible emergency authority for a safer route or assistance. A paper map can help you understand options, but it cannot confirm that a road is open or that exposure conditions have changed.
Include pets and dependent household members
An essential trip is a household decision. Consider the person who needs medication, an oxygen or respiratory device, mobility equipment, communication support, a caregiver, or transportation that cannot be arranged at the last minute. Follow the person's established instructions and contact the clinician, equipment supplier, or emergency authority for the exact need when the plan is uncertain. Do not disclose private health information to a broad group simply to coordinate a ride.
Pets and service animals also affect the decision. Identify who can handle the animal, what food, water, medicines, records, leash, carrier, and sanitation supplies are needed, and whether the destination accepts animals. A local shelter or transportation provider may have its own accessibility, registration, and pet rules. Confirm those details before leaving when time allows. Do not send a child, an older adult, a person with a disability, or an animal into a hazardous area to retrieve another household member. Use the communication plan and request help when officials say travel is unsafe.
Choose a meeting place only under the conditions that make travel permitted. A familiar location may be inside the affected area or along a closed route. The meeting-place plan can help you record a primary place, an alternative, and the hazard conditions that change the choice. Do not send people toward either location until the responsible authority permits that movement.
Official destinations, communication, and return
If officials direct you to a shelter, clinic, reception center, or relocation site, follow its current registration, transportation, accessibility, and pet instructions. Capacity, eligibility, and services can vary by event and location. Ask the authority or facility what to bring and where to go rather than assuming a familiar public building is operating as usual.
Keep communication simple. A charged phone is useful for alerts, but text messages may work when voice calls are congested. Agree on who receives updates, which official channel is being followed, and what information a traveler will send at departure and arrival. If the household separates, use the out-of-town contact and meeting-place choices in the Ready.gov family emergency communication plan. Keep a paper copy as well.
Return only when the responsible officials issue an all-clear or another direct instruction that it is safe to leave or return. CDC guidance for chemical emergencies tells people to follow police, fire, or other local officials about when it is safe to leave or return. A quiet phone, a familiar view from a distance, or a forwarded message is not an all-clear. If the destination is closed, the route has changed, or the household cannot safely return, follow the current direction and ask for assistance.
Travel plans also need seasonal maintenance. School schedules, pet care, weather, transportation, and the official channels used in your area can change. Use a seasonal household plan check to revisit those assumptions in the English version of your household plan, and make the same updates in any Spanish-language records your household uses.
Questions households ask
Is sheltering in place the same as evacuating?
No. Sheltering in place generally means staying in an appropriate indoor location under the current hazard instruction. Evacuation means leaving an area or moving to a designated destination when authorities direct it. Follow the order that applies to the current event and location.
What makes a trip essential?
A threat to life, emergency medical care, a time-critical medication or device need, an official evacuation, or a required official destination can make travel essential. A routine errand or damage check can often wait, but the hazard and the authority's instruction control the decision.
What should a traveler carry?
Carry the identification, medication, required equipment, communication device, charger, water, and animal supplies that the exact trip requires. Follow the instructions for the specific destination and hazard, and do not treat a general kit as a promise that every household need is covered.
When can someone return home?
Return after the responsible authority issues an all-clear or direct instruction that it is safe to leave or return. If conditions change before then, stay in the current safe location and request emergency help for an immediate life threat.
Make the next check now
Write the decision card on paper and place it with your household contacts. Add the official channels your area uses, a person who can receive updates, the people or animals whose needs can make time matter, and the information needed to reach them without exposing anyone to private details. Review the route kit and seasonal plan when routes, school, pets, weather, or transportation change.
When an instruction arrives, pause the nonessential trip, identify the actual need, verify the controlling direction, communicate the plan, and follow the exposure limits for that hazard. Call emergency services for immediate danger. Otherwise, wait for the next official update or all-clear before traveling or returning.
