In moments of crisis—whether due to a natural disaster, widespread civil unrest, or other emergencies—urban environments can suddenly transform into challenging survival scenarios. When conventional resources run out or become inaccessible, improvisation often becomes the key to staying safe, healthy, and resilient. This principle of thinking on your feet is sometimes referred to as “MacGyver” skills, a nod to the television character known for creating solutions out of everyday items. In the realm of Urban SERE (Survival, Evasion, Resistance, and Escape), these improvised tools and repair methods can help sustain you and your loved ones when every second counts.
Below, we will explore how to think creatively about the items around you, how to repurpose common household or urban objects into valuable tools, and how to effect quick repairs that can make a critical difference. All claims are backed by reputable sources, quoted and cited at the end.
The Importance of Improvisation
Improvisation is more than a set of clever hacks; it is about adapting to the rapidly changing environment. According to the U.S. Army Field Manual 3-05.70 (Survival), “The ability to improvise is essential for a soldier in a survival situation” (U.S. Army Field Manual 3-05.70, p. 9-1). This same principle applies to urban civilians. When everyday infrastructure and resources fail, the capacity to adapt can mean the difference between safety and danger.
Why Urban Improvisation Is Unique
Unlike wilderness survival—where natural resources like wood, fresh streams, and wild edibles are part of the landscape—urban environments offer different resources. There might be metal, concrete, glass, and plenty of discarded materials. Recognizing their potential value is key. As the Federal Emergency Management Agency (FEMA) points out: “In a disaster, your environment becomes your toolkit. Familiarizing yourself with various materials now will help you adapt during an emergency” (FEMA, Ready.gov).
Assessing Resources Around You
In an urban crisis, some everyday items quickly become invaluable:
Plastic Bottles: Can be used for water storage, makeshift funnels, or even flotation devices if sealed airtight.
Aluminum Cans: Serve as cooking vessels, reflectors for signaling, or even as improvised stoves.
Duct Tape and Zip Ties: From sealing off doors against contaminants to creating makeshift bandages, these universally praised items can fix countless problems quickly.
Wire Hangers or Scrap Metal: Perfect for creating makeshift hooks, tripods, or structural supports for broken items.
Paracord or Rope Substitutes: In the absence of rope, strips of cloth, twisted plastic bags, or braided fabric can serve similar functions.
Before you begin repurposing, evaluate your immediate needs—water, shelter, first aid, security—and then look for materials around you to meet those needs.
Water Purification Hacks
Clean water is a priority in any survival situation. Unfortunately, in times of crisis, regular water supplies may become disrupted or contaminated. According to the Centers for Disease Control and Prevention (CDC), “Contaminated water can cause illnesses such as cholera, diarrhea, and dysentery” (CDC, Emergency Water Supply).
Boiling with Improvised Containers
If you have access to fire, boiling water is a reliable method of purification. You can do this in small aluminum cans or even steel containers found in a typical household. Ensure you remove any lining from aluminum cans before boiling, and always let them cool safely to avoid burns.
Homemade Water Filter
A quick multi-layer filter can be fashioned using a plastic bottle, gravel, sand, charcoal (from burnt wood), and cloth. The U.S. Army Field Manual 3-05.70 suggests that “A filtering system that passes water through various layers of gravel, sand, and charcoal can greatly reduce contaminants” (p. 10-3). After filtering, always boil or chemically treat the water to ensure it's safe.
DIY Lighting and Cooking Options
In a power outage, having a source of light or a way to cook can significantly improve morale and survival odds.
Improvised Lanterns
A simple lantern can be made using a glass jar or tin can and a piece of cloth or cotton string for a wick. If you have cooking oil or melted wax, place the wick inside and light carefully. Always monitor open flames to avoid accidental fires.
Can Stove (Hobo Stove)
A common DIY design involves taking a tin can (for instance, a large coffee can), punching ventilation holes near the top and bottom, and placing a small fuel source—like twigs, cardboard soaked in wax, or even solid alcohol fuel tabs—inside. The top can be used to hold a small cooking pot or another smaller tin can with water.
Basic Repairs in Times of Crisis
Structural damage to homes, broken doors or windows, and damaged clothing or gear can be serious liabilities during unrest or disasters. Quick fixes with basic items can go a long way toward protecting you from weather, contamination, or intruders.
Patching Windows and Doors
The American Red Cross advises that “When windows are broken or doors are damaged, you lose more than comfort. A compromised entry point can pose a security risk and allow weather or hazardous materials in” (Red Cross, Emergency Resource Guide). Using plastic sheeting (painter’s plastic, garbage bags, or even shower curtains) and duct tape can provide a temporary seal against the elements.
Clothing and Gear Repairs
A sewing kit is ideal, but if you lack one, try these methods:
Duct Tape Mending: Secure tears in jackets, shoes, and backpacks. It won't look pretty, but it often holds long enough to be practical.
Safety Pins or Paper Clips: These can hold together zippers or holes until you can find a more permanent solution.
Wire or Binder Clips: Secure heavier materials like canvas or tarp by folding and clamping them shut.
Multi-Purpose Tools from Simple Items
When you lack a proper toolbox, improvising functional equivalents can save the day.
Screwdriver Substitutes: Use a coin, the tip of a knife blade, or a flattened piece of metal to remove or tighten screws in a pinch.
Hammer Substitutes: If you don’t have a hammer, a heavy rock or pipe can often do the job. Just be mindful of potential hazards like flying debris or personal injury.
Saw or Cutting Edge: A serrated kitchen knife can cut wood (albeit slowly), and a broken piece of glass can work as a rough cutting tool for cordage.
Crowbar Alternative: Sturdy metal pipes or rebar can serve as pry bars for opening jammed doors or crates.
First-Aid Improvisations
Medical resources might be scarce during a crisis. While nothing replaces proper medical equipment and training, certain workarounds can buy valuable time until professional help arrives.
Tourniquets and Slings
The CDC notes: “In extreme situations, controlling bleeding quickly can save lives” (CDC, Stop the Bleed Initiative). A belt, scarf, or even strips of sturdy cloth can function as a tourniquet, though you must apply it correctly to avoid further harm. For slings, a shirt or bandana can immobilize an injured arm.
A piece of stiff cardboard, a ruler, or even sticks from broken furniture can stabilize a sprain or fracture. Secure them with duct tape, cloth strips, or whatever else is on hand.
Sanitation
If clean bandages are unavailable, use the cleanest materials you can find—boil cloth if possible, or use plastic coverings to keep wounds protected from contamination.
Defensive Measures
In times of civil unrest or extreme desperation, situational awareness is the best defense. Still, there are some improvised measures you might consider.
Barricading Doors: Use furniture or sturdy shelving to reinforce doors. Thread rope, paracord, or improvised “rope” made from twisted sheets through door handles and secure it to a heavy object to make forced entry more difficult.
Noise Traps: Stacking cans or bottles as an early warning system can give you a heads-up if someone is moving around your perimeter.
Always follow local laws and prioritize de-escalation and safety. Defensive steps are meant to keep you secure long enough to evacuate or await emergency services.
Mindset and Practice
Cultivating a survival mindset is crucial. Regularly examining your environment for potential resources and brainstorming how to use them can sharpen your improvisational skills. “Adaptation and ingenuity are not purely instinctive. They can be cultivated through practice,” states the U.S. Army Field Manual 3-05.70 (p. 2-5).
Consider taking part in workshops or community preparedness events hosted by organizations like the American Red Cross or your local Community Emergency Response Team (CERT). Even watching tutorials or reading manuals can prepare you to think more creatively about the world around you.
Final Thoughts
Urban SERE involves recognizing that the cityscape itself is full of tools and materials that can be repurposed. In times of crisis—when normal systems collapse—it’s often the resourceful individual who can turn the ordinary into the extraordinary. By honing these “MacGyver” skills, you’re not only better prepared to handle immediate threats but also more capable of helping others around you.
Remember:
Stay Safe: Always ensure your improvisations don’t endanger you or others.
Stay Legal: Respect the law and understand that some improvised methods might be restricted depending on your jurisdiction and the context of the crisis.
Stay Ethical: Use these skills to protect life and property, not to cause harm.
Whether it’s patching a hole in a window with duct tape and plastic or turning an empty soda can into a functional stove, each improvised solution can be a stepping stone to greater resilience and survival. Familiarize yourself with these methods now, practice them where safe and legal, and you’ll be far more confident and capable should an emergency occur.
