Emergency Preparedness Household

South Korea's Ministry of the Interior and Safety (MOIS) recommends every household maintain 30 days of emergency supplies — yet a 2023 government survey found fewer than 12% of Korean families actually have a kit ready. With the Strait of Hormuz effectively shut down since early March 2026 and oil prices spiking past $100/barrel, that gap between recommendation and reality just got dangerous.

This guide combines MOIS and FEMA standards into a single, actionable household emergency checklist you can start building today.

Why "Later" Is No Longer an Option

The U.S.–Iran military conflict that began on February 28, 2026 triggered an immediate closure of the Strait of Hormuz, choking off roughly 20% of the world's daily oil supply. Tanker traffic through the strait dropped to near zero within days. Brent crude surged past $100/barrel, and analysts warn it could climb higher if the blockade persists.

For households, this means potential disruptions to energy, transportation, and supply chains — not just in the Middle East, but globally. South Korea imports over 70% of its crude oil through the Persian Gulf route. The Korean government activated an emergency economic response team on March 1 and began releasing strategic petroleum reserves.

Here's the counterintuitive part: the best time to prepare isn't during a crisis — it's the 48 hours before panic buying empties shelves. If you're reading this, that window is still open.

The 30-Day Household Emergency Checklist

Below is a consolidated checklist drawing from South Korea's SafeKorea portal (MOIS) and FEMA's Ready.gov guidelines. The Korean standard is more aggressive — 30 days of supplies vs. FEMA's 3-day minimum — and given the current geopolitical situation, the 30-day target makes more sense.

Water: The Non-Negotiable Priority

Water is the single most critical supply. The human body survives roughly 3 days without it.

• Minimum: 1 gallon (3.8 liters) per person per day
• Realistic target: 2 gallons per person per day (includes cooking and basic hygiene)
• For a family of 4, 2-week supply: 112 gallons (424 liters)

Store in food-grade containers away from direct sunlight. Rotate every 6 months. Also keep water purification tablets or a portable filter as backup — stored water alone won't last 30 days without taking up enormous space.

Tip: Fill clean 2-liter soda bottles with tap water as a free, space-efficient starting point.

Food: 30-Day Stockpile Basics

South Korea's MOIS specifically recommends rice, instant noodles, flour, and canned goods as the foundation. FEMA emphasizes non-perishable items requiring no refrigeration or cooking.

The best approach combines both: a core of shelf-stable staples plus ready-to-eat options for the first 72 hours when you may not have cooking fuel.

Tip: Buy what you already eat. Exotic survival food you've never tasted leads to waste and low morale.

Cooking & Fuel

Korea's MOIS specifically recommends 15 or more butane gas canisters — a detail most English-language guides skip entirely. In a prolonged power outage, your electric stove is useless.

• Portable butane stove + 15–20 canisters
• Metal pots, cups, and utensils (not plastic)
• Manual can opener (critical — often forgotten)
• Waterproof matches and a lighter

Tip: One standard butane canister provides roughly 1–1.5 hours of cooking. At two meals per day, 15 canisters covers about 10 days of cooking.

Medical Supplies & Medications

A medical kit serves as your household's urgent care when pharmacies and hospitals may be overwhelmed or inaccessible.

First Aid Kit Essentials

Medications

Korea's MOIS checklist covers: disinfectants, fever/pain reducers, digestive aids, anti-diarrheal medication, burn ointment, hemostatic agents, and anti-inflammatory drugs.

Add to this:

• Prescription medications: 30-day supply minimum. Talk to your doctor about an emergency refill now — don't wait until pharmacies are rationing.
• Children/elderly-specific meds: MOIS explicitly notes age-appropriate medications for vulnerable family members.
• Prescription glasses or contacts: A spare pair could be invaluable.

Tip: Photograph all prescription labels and store images in your phone and a USB drive. In an emergency, this speeds up refills enormously.

Power, Communication & Documents

Electricity and internet are the first things to go in a crisis. Plan for it.

Power

• Flashlights with extra batteries (LED lasts longer)
• Battery-powered or hand-crank radio (MOIS and FEMA both list this as essential)
• Portable power bank (10,000+ mAh) — keep it charged
• Candles (10+) with stable holders

Communication

• Establish a family meeting point in case you're separated
• Designate an out-of-area contact person (local lines often jam; long-distance may work)
• Keep emergency numbers written on paper — not just in your phone
• Download offline maps of your area

South Korea's emergency alert system now broadcasts in 19 languages. Save the SafeKorea portal (safekorea.go.kr) and the emergency number 119 (fire/ambulance) and 112 (police).

Critical Documents

Store copies in a waterproof bag:

• ID cards / passports
• Insurance policies
• Bank account information
• Property deeds
• Medical records and prescription lists
• Emergency contact list

Tip: Scan everything to a USB drive and a secure cloud service. Physical and digital redundancy is the point.

Clothing, Shelter & Sanitation

These categories get overlooked until they become urgent.

Clothing

MOIS recommends at least one warm outfit and sturdy shoes per person. Beyond that:

• Rain gear
• Work gloves
• Warm layers (even in spring — nighttime temperatures drop)
• Sturdy closed-toe shoes or boots

Sanitation

When water supply is limited, hygiene prevents disease outbreaks:

• Garbage bags (heavy-duty, multiple uses)
• Hand sanitizer and disinfecting wipes
• Soap
• Toilet paper (more than you think)
• Plastic sheeting and duct tape (for improvised shelter-in-place sealing)
• Dust masks or N95 respirators

Tip: A 5-gallon bucket with heavy-duty trash bags functions as an emergency toilet. It's not glamorous, but it's a real solution when plumbing fails.

Your 48-Hour Action Plan

Don't try to buy everything at once. That's how you end up overwhelmed and $500 poorer with half the wrong items.

Key Takeaway

The current Hormuz crisis is a concrete reminder that supply chain disruptions can escalate faster than anyone expects. You don't need a bunker. You need 30 days of basics, a plan, and the discipline to act before — not during — a shortage.

Start with water and 72 hours of food today. That single step puts your household ahead of the vast majority.

Your next actions:

1. Visit Ready.gov/kit or SafeKorea for official government checklists
2. Audit your home using the 48-hour action plan above
3. Set a calendar reminder to rotate water and check expiration dates every 6 months

Information current as of March 2026. Emergency preparedness recommendations may change as the geopolitical situation evolves. Always follow guidance from your local government and emergency management authorities.
