Body & Survival: Field Diagnostics for Staying Alive

Practical, actionable. No hedging. When you need to know, you need to know now.

PART ONE: DANGER ASSESSMENT

Is This Electrical Wire Dangerous?

Visual Inspection — Work outward to inward:

What You See	Urgency
Wire intact, insulation smooth, no discoloration	🟢 Monitor
Insulation cracked, brittle, or discolored	🟡 Address soon
Insulation melted, bubbled, or scorched	🔴 Act immediately
Exposed copper conductor visible	🔴 Act immediately
Arcing, sparking, or flickering	🔴 Act immediately
Wire near or in water	🔴 Act immediately

The smell test: Burning plastic smell near an outlet, panel, or appliance = 🔴 Act immediately. This is pre-fire, not post-fire. Turn off the circuit at the breaker.

Proximity rules: - Human body clearance from suspected live wire: minimum 10 feet if outdoors, more if wet - Never touch a wire to test voltage — use a non-contact voltage tester (under $20, keep one) - Water + electricity: assume any submerged wire is energized until proven otherwise

Downed power line protocol: 1. Stay back minimum 30 feet (the "step potential" danger zone extends further than the wire) 2. Do NOT approach to help someone in a car — call 911 3. If you are IN a car that hits a downed line: stay inside, call 911, wait for utility workers 4. If you MUST exit a car touching a live wire: jump clear with both feet together, shuffle-hop away — never walk normally (step potential kills) 5. Never use a rope, stick, or rubber glove to move a live line — consumer items are not rated for line voltage

Is This Water Safe to Drink?

Sensory hierarchy (run all three, not just one):

Visual: Clear ≠ safe, but these are red flags: - Cloudiness or turbidity → suspended bacteria/sediment - Blue-green tint → algae bloom (cyanotoxins, extremely dangerous) - Brown/orange → rust, iron, or tannins (may be harmless, may not) - Oily sheen that breaks into geometric patterns (not rainbow-swirls) → petroleum contamination 🔴

Smell: - Bleach/chlorine → municipal treatment, generally okay - Rotten eggs (sulfur) → hydrogen sulfide, possibly bacterial; test before drinking - Chemical/petroleum → 🔴 do not drink - No smell → necessary but not sufficient for safety

Taste (if smell passed): - Metallic → heavy metals or old pipes - Chemical/bitter → contamination - No taste → still may contain biologicals

Biological vs chemical threat distinction — critical: - Biological (bacteria, protozoa, viruses): can be treated with boiling (1 minute, 3 minutes at altitude), filtration (0.1 micron or better), chemical treatment (iodine, chlorine tablets), or UV - Chemical (pesticides, heavy metals, petroleum): boiling concentrates chemical contaminants. Filter only with activated carbon rated for the specific chemical, or don't drink it.

Field testing sequence: 1. Look → smell → small taste test (spit, don't swallow) 2. If in doubt: boil for biologicals, find an alternative source for suspected chemical contamination 3. Clear running water from upstream (above human habitation) is lowest-risk natural source 4. Stagnant water is always higher risk regardless of appearance

Is This Ice Safe to Walk On?

Thickness rules (clear, solid ice):

Ice Thickness	Safe For
Less than 2"	🔴 No one — stay off
2"	🟡 One person on foot (marginal)
4"	🟢 One person on foot
5-7"	🟢 Snowmobile
8-12"	🟢 Small group / ATV
12"+	🟢 Small vehicle

These numbers assume clear, solid, blue ice. Reduce safe thickness by 50% for: - White/opaque ice (air bubbles = 50% density) - Layered ice with water between layers - Ice near inflows/outflows, pressure cracks, or springs - Ice formed on moving water

Color reading: - Blue/black = dense, strong ice 🟢 - White/gray = air-saturated, weak 🟡 - Slush gray = near-melt condition 🔴 - Dark spot from below = thin zone, open water below 🔴

Sound assessment: - Hollow boom when you step = ice flexing, water space below 🔴 - Sharp crack = stress fracture propagating — back off immediately using same tracks - Creaking/groaning = normal thermal expansion in cold conditions 🟡

If you fall through: - Don't panic — your clothing traps air (30–90 seconds before hypothermia impairs you) - Turn toward direction you came (that ice held you) - Kick feet to horizontal, claw elbows onto ice edge, slide out like a seal — do NOT stand up - Roll away from the hole, don't walk

Is This Building Structurally Sound?

Crack assessment — cosmetic vs structural:

Crack Type	Indicator	Urgency
Hairline, paint only	Cosmetic settling	🟢 Monitor
Vertical crack, <1/4"	Minor settling, common	🟢 Monitor
Horizontal crack in basement wall	Lateral soil pressure — structural	🔴 Act immediately
Diagonal crack from door/window corner	Differential settlement	🟡 Address soon
Crack wider at top than bottom	Active settling	🟡 Address soon
Crack with displacement (one side higher)	Structural failure	🔴 Act immediately
Stair-step crack in brick/block	Foundation movement	🟡→🔴 Evaluate urgency

Foundation check: - Walk the perimeter — look for soil pulling away from foundation (shrinkage/settling) - Visible gaps between foundation and framing above = serious - Efflorescence (white mineral deposits) on concrete = chronic water infiltration

Doors and windows: - Doors/windows that suddenly won't close or have new gaps = building racking (structural shift) - Multiple doors affected simultaneously after no weather event = 🔴 evaluate immediately

Water damage indicators: - Soft floors (especially near bathrooms/kitchens) = subfloor rot - Ceiling stains: active = darker/wet ring; old = dry, chalky ring - Musty smell throughout = chronic moisture = mold likelihood

After earthquake, flood, or fire: - Do not re-enter until cleared by structural engineer or building inspector - Gas smell = leave immediately, do not use electrical switches

Is This Neighborhood Safe? Environmental Reading

Physical environment cues:

Observation	Interpretation
Broken windows, boarded buildings	Disinvestment, reduced guardianship
Working street lights	Maintained infrastructure 🟢
No working lights, bulbs broken	Low deterrence environment 🟡
Graffiti: tags only	Territory marking, moderate signal
Graffiti: crossed-out tags	Active territorial conflict 🔴
People on streets, mixed ages	Organic community presence 🟢
Isolated, no foot traffic at peak hours	No natural surveillance

Situational awareness: - Dead ends and poor sight lines = reduced escape routes = 🟡 - Who's watching you? People who look without purpose, track your movement = stay aware - Follow your threat detection instinct — discomfort without visible cause is data, not paranoia

Rip Current Identification and Escape

How to spot one from shore: - Discolored (murkier/foamy) channel cutting through breaking waves - Choppy, churning surface in a channel 20–100 feet wide - Noticeable gap where waves aren't breaking (the current is suppressing wave formation) - Debris or foam moving steadily seaward

Escape: 1. Don't fight it swimming directly toward shore — you'll exhaust yourself 2. Swim parallel to shore until out of the current (typically 20–100 ft) 3. Then swim diagonally toward shore 4. If you can't escape: float, wave for help — rip currents don't pull you under, they pull you out

Avalanche Terrain Assessment

Red flags:

Sign	Urgency
Recent avalanche debris visible on slope	🔴 Active avalanche path
"Whumpfing" sound underfoot (snow settling)	🔴 Unstable snowpack
Shooting cracks radiating from footsteps	🔴 Extremely unstable
Slopes 30–45° (prime avalanche angle)	🟡 Requires assessment
Convex roll (crest of slope)	🔴 Highest stress zone
Lee slopes with wind-deposited slabs	🟡 Slab risk
Recent heavy snow (24–48hrs)	🟡 Loading risk
Recent rapid warming or rain on snow	🔴 Wet avalanche risk

Survival: - Triggered: try to ski/run to side of slide path - Caught: discard poles, fight to stay on surface (swimming motion) - Buried: create air pocket before snow sets (hand over face, expand chest), spit to find down (gravity), dig toward light — or stay still to conserve oxygen

Lightning Risk (The 30/30 Rule)

30/30 Rule: - If time between lightning flash and thunder is 30 seconds or less → seek shelter immediately (storm within 6 miles) - Wait 30 minutes after the last thunder before resuming outdoor activity

Position hierarchy (safest to most dangerous): 1. 🟢 Substantial building with plumbing/electrical (Faraday cage effect) 2. 🟢 Hard-topped metal vehicle (not convertible) 3. 🟡 Low-lying open area, away from trees 4. 🔴 Open water, elevated terrain, lone trees, metal fences, open structures

Lightning position (if caught in open): - Crouch low, feet together, on balls of feet (minimize ground contact area) - Do NOT lie flat - Move away from trees, poles, metal objects - Separate from other people by 50+ feet (reduces group strike risk)

Wildfire Evacuation Decision Tree

Is there an official evacuation order?
    YES → Leave immediately. Do not wait.
    NO ↓

Can you see smoke or flames?
    YES, visible flames < 1 mile → Leave now.
    YES, distant smoke only ↓

Is your route out still clear?
    UNKNOWN → Leave now (fire moves faster than you think)
    YES ↓

Do you have >2 hours of prep time?
    NO → Leave now
    YES → Implement "go bag" protocol, prepare structure, leave early

Pre-evacuation actions (only if you have time AND route is clear): - Close all windows/doors (buys 30–60 min against embers) - Move combustibles away from house - Fill gutters with water if possible - Leave lights on (visibility in smoke for firefighters) - Leave doors unlocked

Flash Flood Indicators

Warning signs: - Rapid rise in stream/creek level - Water turning muddy without local rain = upstream event - Roaring sound from upstream canyon or drainage - Rain of any intensity in narrow canyons — you don't need to see it raining where you are - Official flash flood watch/warning in area

In a canyon or wash: 🔴 Move to high ground immediately if ANY of the above are present. Flash floods travel faster than a person can run.

In a vehicle: Do not drive through flooded roads — 2 feet of moving water can sweep away most vehicles. "Turn around, don't drown."

PART TWO: FOOD SAFETY DIAGNOSTICS

Meat Assessment

Raw meat — use all senses:

Sign	Decision
Off-pink/gray surface	🟡 Check smell — surface oxidation is normal
Slimy texture	🔴 Discard
Sour, ammonia, or sulfur smell	🔴 Discard
Gray throughout (not surface only)	🔴 Discard
Normal pink/red with faint meat smell	🟢 Safe to cook

Cooked meat: - Smell test: sour, off, or "wrong" = discard - Slimy surface on cooked meat = bacterial growth = 🔴 Discard - Left out >2 hours at room temp (>40°F) = 🔴 Discard (no exceptions — cooking won't neutralize toxins already produced)

Fish Assessment

Fresh fish indicators: - Smells like the ocean (clean, briny) = 🟢 - "Fishy" smell = beginning of spoilage 🟡 - Strong ammonia/sour smell = 🔴 Discard - Eyes should be clear and slightly bulging (sunken/cloudy = old) - Flesh should spring back when pressed (doesn't = spoiling) - Gills should be bright red (gray = old)

Dairy Assessment

Milk: Smell first. Sour smell = 🔴. Slightly off but not sour = drink today or cook with. Cheese: Hard cheeses — cut 1" around visible mold, eat remainder. Soft cheeses — mold = 🔴 discard entire container (mold penetrates throughout). Yogurt: Liquid on top = normal whey separation, stir it. Off smell or pink/orange mold = 🔴 Discard.

Egg Float Test

Fill a bowl with cold water: - Sinks, lies flat = 🟢 Fresh (air cell tiny) - Sinks, stands on end = 🟡 Use soon (larger air cell) - Floats = 🔴 Discard (large air cell = decomposition gas)

Crack and smell: Bad eggs have unmistakable sulfur smell. When in doubt, crack into a separate bowl before using.

Bread Mold Rules

Visible mold on bread: 🔴 Discard the entire loaf. Bread is porous — mold filaments penetrate invisibly throughout, even if only visible in one spot.
Exception: Some artisan breads develop surface bloom that is not mold (white flour dusting). Rub it — flour wipes off, mold doesn't.

Produce Assessment

Soft spots: On firm produce (apple, potato, melon) = cut away generously + 1 inch around; the rest is safe. On soft produce (tomato, berry) = discard if >30% affected.
Mold on produce: Firm items (cabbage, carrots, bell peppers): cut generous margin, safe to eat remainder. Soft items: discard.
Off smell in produce: Always discard (bacteria or decomposition)

Mushroom Safety — Absolute Rules

The only safe rule: 100% positive identification by an expert, or don't eat it.

Why folk tests fail: - The "silver spoon turns black" test: false. Has no basis in chemistry. - "Peeling cap = safe": false. Death Cap (Amanita phalloides) peels easily. - "Animals eat it, so safe": false. Squirrels can process toxins humans cannot. - "It doesn't taste bitter": false. Death Cap reportedly tastes pleasant. - Cooking does NOT neutralize Amanita toxins.

Species to categorically avoid without expert confirmation: - Any white gilled mushroom (Death Cap, Destroying Angel family) - Any small brown mushroom (LBM = "Little Brown Mushroom" — dozens of toxic species) - Any mushroom with a volva (cup at base) = suspect Amanita

Symptoms of Amanita poisoning: Delayed 6–24 hours. You feel fine, then organ failure begins. By the time symptoms appear, liver damage may be irreversible. If any mushroom consumption is suspected: emergency room, not wait-and-see.

Expiration Dates Decoded

Label	Meaning	What To Do
Sell By	Retailer's stock rotation guide	Product good days-weeks beyond this
Best By / Best Before	Peak quality date	Usually safe after; quality declines
Use By	Safety date (infant formula, some dairy)	Follow strictly for these categories
Freeze By	Optimal freeze date, not safety date	Freeze before this for best results

Real safety guide: Your senses beat any date stamp for most foods. Dates are quality estimates, not microbial timers. Exceptions: infant formula, raw meat, and oysters — treat use-by dates as hard limits.

PART THREE: BODY LITERACY

Referred Pain Map

Pain location ≠ problem location. Key patterns:

Where You Feel It	Could Be
Left arm/jaw/shoulder	Heart 🔴
Right shoulder (especially tip)	Gallbladder/liver
Between shoulder blades	Aortic dissection 🔴, esophageal, gallbladder
Lower back	Kidneys, ovaries, aortic aneurysm
Groin	Kidney stones, hernia, hip
Shoulder tip (either)	Diaphragm irritation (internal bleeding, ruptured spleen)
Ear/jaw	Tooth, TMJ, heart (left side)
Navel area radiating right	Appendicitis (pain migrates to right lower quad)

Rule: New, severe, or unusual pain with no obvious cause → medical evaluation. Don't self-diagnose based on location alone.

ABCDE Mole Rule

Letter	What to Check	Concern
A — Asymmetry	One half doesn't match the other	🟡
B — Border	Irregular, ragged, notched, or blurred edges	🟡
C — Color	Multiple colors, uneven distribution	🟡
D — Diameter	Larger than 6mm (pencil eraser)	🟡
E — Evolving	Any change in size, shape, color, or new symptoms (bleeding, itching)	🔴

Any single ABCDE flag = dermatologist appointment. Evolving (E) is the most important — a changing mole is more concerning than a stable atypical one.

Heart Attack Symptoms by Gender

Classic symptoms (more common in assigned-male-at-birth individuals): - Chest pressure, tightening, or crushing sensation - Pain radiating to left arm, jaw, or neck - Shortness of breath - Sweating, nausea

Atypical symptoms (more common in assigned-female-at-birth individuals, but anyone can have these): - Unusual fatigue (days before event) - Indigestion or jaw/back pain without chest symptoms - Nausea and vomiting - Shortness of breath without chest pain - Feeling of dread or "something is wrong"

The critical mistake: Dismissing symptoms because "it doesn't feel like a heart attack" or waiting to see if it passes. The atypical presentation is the one that gets people killed.

🔴 If suspected: call emergency services immediately, chew aspirin (325mg, if not allergic), sit or lie down, do not drive yourself.

FAST Stroke Assessment

Letter	Test	Positive Sign
F — Face	Ask them to smile	One side droops
A — Arms	Ask them to raise both arms	One drifts down
S — Speech	Ask them to repeat a phrase	Slurred, strange, or unable
T — Time	Note exact time of symptom onset	Call emergency services NOW

Why time matters: Stroke treatment (tPA, thrombectomy) has a 3–4.5 hour window from symptom onset. Minutes = brain tissue.

Additional signs: Sudden severe headache ("worst of my life"), sudden vision loss in one eye, sudden loss of balance.

Concussion Post-Impact Checklist

Immediate red flags requiring emergency care: - Loss of consciousness (any duration) 🔴 - Seizure 🔴 - Repeated vomiting 🔴 - Worsening headache over hours 🔴 - One pupil larger than the other 🔴 - Cannot recognize people or places 🔴 - Clear fluid from nose or ears 🔴

Monitor for (someone must watch them for 24 hours): - Confusion, difficulty concentrating - Sensitivity to light or noise - Sleep disturbance - Mood changes - Headache that doesn't improve

Return to activity: Never return to sports or high-risk activity same day as suspected concussion. "When in doubt, sit it out."

Dehydration Levels and Response

Level	Signs	Response
Mild	Thirst, dark yellow urine, slight fatigue	🟡 Drink water now
Moderate	Headache, dizziness, dry mouth, muscle cramps, urine dark orange	🟡 Oral rehydration, rest in shade/cool
Severe	Confusion, rapid heart rate, rapid breathing, sunken eyes, no urination >8hrs	🔴 IV fluids needed — emergency care

Urine color guide: Pale yellow = well hydrated. Dark yellow = drink more. Amber/orange = moderate dehydration. Brown = severe/possible kidney issue 🔴.

Heat Exhaustion vs Heat Stroke

Condition	Skin	Mental Status	Temperature	Action
Heat Exhaustion	Cool, pale, sweating	Alert, dizzy	Normal–100°F	🟡 Move to cool area, hydrate, cool skin
Heat Stroke	Hot, red, DRY	Confused, unresponsive	>103°F	🔴 Emergency — cool aggressively while waiting for services

Heat stroke cooling: Ice water immersion is fastest. If unavailable: cold wet towels to neck, armpits, groin (where blood vessels are close to surface). Fan the patient. Do not give fluids if they're confused (aspiration risk).

Hypothermia Staging

Stage	Core Temp	Signs	Action
Mild	90–95°F	Shivering, poor coordination, slurred speech	🟡 Remove wet clothing, insulate, warm beverages if conscious
Moderate	82–90°F	Shivering stops (bad sign), confusion, stiff muscles	🔴 Gentle handling, no rubbing, horizontal transport, warm core
Severe	<82°F	Unconscious, no palpable pulse	🔴 Emergency — CPR if no pulse, hospital ASAP ("not dead until warm and dead")

Warning: Shivering stopping is NOT improvement — it means the body has exhausted its ability to self-warm.

Allergic Reaction Severity Scale

Level	Signs	Action
Mild	Hives, itching, runny nose, watery eyes	🟡 Antihistamine, monitor
Moderate	Widespread hives, swelling (not throat), GI upset	🟡 Antihistamine + monitor closely
Severe (Anaphylaxis)	Throat tightening, difficulty breathing, voice change, drop in blood pressure, pale/blue skin, rapid pulse	🔴 Epinephrine (EpiPen) immediately, call emergency services, lie down with legs elevated

Anaphylaxis decision tree:

Exposure to known or suspected allergen
    + ANY of: throat swelling, difficulty breathing, voice change, 
      dizziness/fainting, rapid pulse, widespread hives + GI symptoms
    → Use epinephrine NOW (even if unsure)
    → Call emergency services
    → Second dose in 5-15 min if no improvement
    → Antihistamines are NOT a substitute for epinephrine in anaphylaxis

Body Odor as Health Indicator

Odor	Location	May Indicate
Fruity/sweet breath	Mouth	Diabetic ketoacidosis 🔴, ketogenic diet
Ammonia breath	Mouth	Kidney disease or failure
Fishy breath	Mouth	Liver disease, trimethylaminuria
Fecal breath	Mouth	Bowel obstruction 🔴, severe constipation
Sweet-musty breath	Mouth	Liver failure (fetor hepaticus)
Ammonia body odor	Skin	Kidney dysfunction
Fruity overall	Skin	Uncontrolled diabetes
Fishy body odor	Skin	Trimethylaminuria, liver issues
Foul-smelling urine	Urine	UTI, dehydration, certain foods
Sweet-smelling urine	Urine	Diabetes, PKU
Dark/black stool odor	Stool	Upper GI bleeding 🔴 (digested blood)

Note: Single instances of unusual odor after specific foods are usually dietary. Persistent, new, or unexplained odor warrants medical evaluation.
