Shelter in Place Kit and Guide – How Duct Tape and Plastic can Save Your Life
This is an updated guide on Shelter in Place Kits. Our first guide was published in 2017, and we will continue to update this guide as new information emerges and to reach a larger audience about the importance of being prepared with a shelter-in-place kit.
A Shelter in Place kit is a kit that allows you to seal off a building, room, or vehicle to make it as airtight as possible. This kit can greatly increase your survivability against chemical, biological, and radiological exposure. The kit itself doesn’t have to be anything fancy and is very simple to put together.

Roll of Duct Tape – Duct tape is great, and you probably already have some laying around. Chances are, you might not have enough. To seal one room, you will need at least one 30 yard roll. When used properly, these kits use a lot of tape and plastic sheeting.
Plastic Sheeting – You can get 4-6 mil sheeting of any color, but I prefer 4 mil since you can contour it to odd-sized doors, windows, and vents. I also prefer black sheeting since it can double as a resource to cover windows for light discipline. The 10-foot wide sheeting we suggest may seem like overkill, but it is always better to cut plastic down to cover an opening than to seam it together with duct tape- there is almost always a hole!
How to Shelter in Place
The shelter-in-place kit is used for three types of scenarios: chemical, biological, or radiological events. These events usually come with a warning, and possibly even a message to shelter in place. Even with a warning, being able to shelter in place quickly is the most important part of the entire plan. While a radiological event could take hours to contaminate, a chemical release would usually only give you minutes to become airtight. Follow the following steps, in order:
- Close and lock all windows and doors. Leaving any of these open would just be unwise.
- Shut off your HVAC system. Do not pull any air in from the outside.
- Shut off any fans. Quit circulating air within your home.
- Go to your designated Shelter in Place room. It should be on the top story of your home and towards the center. The higher the room, the better since chemicals and other contaminants are heavier than air and tend to settle in clouds at ground level.
- Cut plastic to cover your doors and windows in this room. Some people choose to pre-cut plastic to the size of their doors and windows to save time at this step. I don’t suggest this, however, since that may affect your plans if you have to switch Shelter in Place rooms for any reason.
- Tape the plastic to the frames to create airtight barriers. Use plenty of duct tape on areas where you are not sure it has sealed- better safe than sorry.
- Cut plastic and tape over any air intakes or exhaust inside the room.
- Turn on a radio and stay informed on when conditions are safe for you to evacuate.

Why You Should Have a Shelter in Place Kit
Evaluate the threats that apply to your area. Do you live close to military bases (attacks), industrial areas (chemical accidents), or a nuclear power plant? (radiological contamination) If you perceive any threat that would include a chemical, biological, or radiological hazard, you need to put together a Shelter in Place Kit.
The kit is very easy to put together- the plan is much harder to execute quickly. In a life or death situation, you may be surprised at how hard it is to cut and apply plastic to windows and doors. Practice can make perfect, so a dry run is never a bad idea.
Keep your kit in your designated shelter-in-place room to save a little more time and to know where it is. Let your family in on the plan, so they know what to do as well. Some believe the kit is not worth it because you will “suffocate to death”.
The Math on Why You Won’t Suffocate
A 12’ x 12’ x 12’ (pretty small) room is almost 50,000 liters of air. A person breaths about 10,000 liters of air per day- but doesn’t use all the oxygen they breathe– they exhale a good portion. This allows five people to survive at least a day, or one person to survive for at least five.
The Shelter in Place kit is designed to be used only for a few hours. Chemicals you can typically wait out, and radiological exposure forces you to evacuate eventually anyways- you are just sheltering for the duration Alpha and Beta particles are being emitted. Once those have settled, you will need to evacuate to avoid long-term gamma radiation exposure.
Vehicle Shelter in Place
Shelter in Place in a vehicle is a different story. The steps to do this are simpler than a room- you turn off the AC/heater fan and close all the vents with duct tape. It is advised that you turn your car off, but in this situation, you really don’t have that much air.
Staying mobile and continuing to evacuate may be a priority since you only have about 4 hours of air in your average car. You may have to make that judgment call.
The Final Word
As far as specialized kits come, the Shelter in Place kit is pretty cheap and easy to put together. It can save your life in the rare scenario where you find yourself needing it, but it can also double for other purposes.
Duct tape and plastic sheeting have countless uses just by themselves, so there is no reason not to put this kit together. If you are looking to learn more about the components or survival in-place (bug-in) kits, check out:
