Extended Bunker Living: Shelter Survival Guide

Create two openings if possible—one high for intake, one low for exhaust. Seal unused openings completely. Open doors or hatches for 5–10 minutes daily if safe. Use open containers of baking soda to absorb carbon dioxide. Count occupants and monitor for headaches, dizziness, or lethargy—signs of poor air. If using generators, keep outside and run fuel pipes in.

Never run gasoline generators, charcoal, or fuel heaters inside—they produce deadly carbon monoxide.

Store 1 gallon per person per day for drinking and basic hygiene. Use food-grade containers and rotate every 6 months. Add 2–3 drops unscented bleach per gallon if storing longer than 2 weeks. Mark containers with date and contents. Keep water elevated for gravity distribution. Boil contaminated water at a rolling boil for 1 full minute, or add 6 drops bleach per gallon and wait 30 minutes.

Stock non-perishable, high-calorie foods: canned meat, peanut butter, oats, beans, crackers, dried fruit, nuts. Aim for 2,000 calories per person daily. Eat high-fat and high-protein items first—they sustain longer. Prepare meals at set times to anchor routine. Keep a detailed log of consumption. Distribute portions evenly. Serve warm food when possible—it aids digestion and morale.

Designate one area as toilet and washroom. Use a bucket with seat and plastic bags—tie bags and store separately until safe to dispose. Dig a latrine outside only if shelter is not sealed. Use wet wipes or wash with minimal water. Set up hand-sanitizer stations at meal prep areas. Wash hands with rationed soap and water after toilet use and before food prep. Dispose of waste 50+ feet from water sources.

Do NOT open sealed shelter for waste disposal during active threats.

Keep daily routine: mealtimes, exercise, sleep schedule. Assign tasks (water manager, food monitor, air checker) to build purpose. Use light sources—candles or flashlights—to regulate sleep cycles. Maintain contact with other occupants through conversation. Limit news and communication device use. Ration recreational items (books, cards, games) to maintain morale. Acknowledge fear and grief—it is normal. Rotate responsibilities to prevent burnout.

Do NOT emerge based on time elapsed or silence alone. Establish decision criteria in advance: official all-clear from authorities, lack of sound or activity for 24+ hours, air quality visibly improving, surrounding areas showing signs of normalcy. Send one person outside briefly to observe and report. If threats resume, retreat immediately. Maintain communication with neighbors if possible. Emergence must be a collective decision, not individual.

Premature emergence is more dangerous than extended shelter—wait for clear evidence of safety.
