Keep the body
working when it needs to.

Injury prevention for real chores. Basic body maintenance for extended disruptions. The small things that determine whether you stay functional across days, not just hours.

The compounding problem

An injury during an emergency is two problems at once.

A back strain during post-storm cleanup does not just hurt — it removes a capable person from the household's working capacity at exactly the moment that capacity is needed. A bad blister on day two of an evacuation changes the timeline and the decision options.

Most emergency injuries are not caused by the emergency itself. They are caused by people doing familiar physical tasks — shoveling, lifting, climbing ladders — without the technique or preparation those tasks require at higher intensity or longer duration.

This chapter covers the injuries that actually happen: back strains, foot problems, hand and wrist injuries, falls, and the slow-developing issues that come from days of sustained physical work without adequate body maintenance.

What actually injures people during emergencies1

Back strain — improper lifting and shoveling

Most common

Falls — ladders, rooftops, debris-covered ground

Most serious

Foot injuries — blisters, debris penetration, trench foot

Very common

Hand and wrist — tool use, gripping, falls

Common

Heat illness — sustained outdoor work without hydration

Preventable

Overexertion — cardiac events from unaccustomed work

Serious, rare

Prevention

The four highest-risk emergency tasks.

Each has a correct technique that reduces injury risk significantly. Most injuries happen when people apply ordinary-day effort to emergency-day duration and intensity.

01

Shoveling

Snow, debris, soil — the back injury that sends people to the ER every winter

Shoveling is a combination of hinge, carry, and twist — three patterns that each carry injury risk, combined at high repetition under load. Most injuries occur from loading too much per scoop, twisting at the waist to throw, or starting cold.

Correct technique

Use a bent-handle shovel to reduce forward lean

Bend at hips and knees — not the waist

Keep loads small: half-full scoop, more often

Pivot your feet to throw — never twist the spine

Walk to the disposal point rather than throwing far

Take a 2-minute break every 15–20 minutes

Who is at higher risk

Adults over 55, anyone with known heart disease or high blood pressure, and anyone who is sedentary year-round. Heart rate during shoveling can reach 75–85% of maximum in middle-aged adults.2

Stop if you experience chest tightness, unusual shortness of breath, dizziness, or pain radiating to the arm or jaw.

02

Ladder work

Falls from ladders are the leading cause of serious injury in post-storm cleanup

Every year, post-storm injuries spike from homeowners on ladders in conditions they would not normally attempt. Fatigue, urgency, wet surfaces, and unfamiliarity with ladder dynamics combine to produce serious falls.

Rules that prevent falls

Three points of contact at all times

Set base 1 foot out for every 4 feet of height

Never stand on the top two rungs

Face the ladder when climbing and descending

Never lean so belt buckle passes outside side rails

Do not work from a ladder when fatigued

When to stop

Wet conditions, wind above 15 mph, darkness, fatigue, and working alone at height are each sufficient reasons to stop and wait. No roof repair is worth a fall. Most tasks that take people onto ladders during emergencies can wait 24 hours for safer conditions.

03

Sustained lifting and carrying

The hinge pattern under fatigue — when form breaks down

A single heavy lift rarely injures. Repeated lifting under fatigue — the 30th sandbag, the 15th water container — injures because form degrades as muscles tire. The back rounds, the core stops bracing, and the load transfers to passive structures not designed for it.

How to sustain form under fatigue

Set a form check reminder every 10 reps or 10 minutes

Pause and reset before each lift — do not rush

Reduce load before form breaks, not after

Use a 2-person carry for loads over 50 lbs

Rotate tasks to give back muscles recovery time

Warning signs to respect

Localized lower back tightness after 20+ reps is normal muscle fatigue — take a break. Sharp pain during a lift, pain that radiates down a leg, or numbness in the legs after lifting are warning signs to stop entirely. Do not push through radiating pain — it indicates nerve involvement.

04

Moving over debris and unstable ground

Ankle sprains, puncture wounds, and falls from tripping

Post-storm environments involve debris, wet surfaces, and ground hazards invisible under water or snow. Moving quickly through these conditions produces ankle sprains and puncture wounds. Footwear is the primary protective factor — and it must be owned and broken in before the emergency.

Footwear requirements

Steel or composite toe caps for debris environments

Puncture-resistant midsoles where nails are possible

Ankle support for uneven or shifting terrain

Non-slip outsoles for wet surfaces

Must already be owned and broken in

Movement technique

Slow down. The time saved by moving quickly through a debris field is negligible compared to the time lost to an ankle sprain. Test footing before committing weight. Use a stick to probe ahead in flooded or snow-covered areas. Move in short steps with lower center of gravity.

Daily maintenance

Five body systems that need daily attention.

During multi-day disruptions, small maintenance failures compound. A blister ignored on day one is a serious mobility problem by day three.

Feet

The highest-consequence body maintenance item during any extended physical scenario. Foot problems shut down mobility faster than any other common injury.

Blisters: Drain with a sterile needle. Do not remove the skin — it is a protective barrier. Cover with moleskin cut to a donut shape around the blister, not over it.

Wet feet: Change socks when wet. Moisture causes trench foot within 12–24 hours of continuous wet exposure.

Daily inspection: Check both feet each evening for hot spots, redness, and skin breakdown. Address early.

Skin and hands

Hands are your primary tool. Cuts, abrasions, and cracks compromise grip and introduce infection risk when normal hygiene is disrupted.

Cuts and abrasions: Clean with water immediately. Apply antibiotic ointment and cover. Change dressings daily. Watch for infection: increasing redness, warmth, swelling, or pus.

Gloves: Wear them for tool work and anything in flood water. Flood water contains sewage and chemical contamination.

Cracking: Apply lotion before bed. Cracked skin is painful and an infection entry point.

Teeth and mouth

Dental pain during a multi-day emergency when dental care is unavailable is a significant comfort and function issue. Prevention is the only realistic option.

Basic maintenance: Brush twice daily even with limited water. A small amount is enough — spit rather than rinse if water is scarce.

Emergency dental kit: Temporary filling material (Dentemp), dental wax, over-the-counter dental pain relief. Under $15 at most pharmacies.

Eyes

Debris, dust, and particulate matter are common in post-storm environments. Eye injuries are among the most preventable emergency injuries.

Eye protection: Safety glasses or goggles for any cutting, sawing, or work in dusty/debris environments. Not sunglasses — rated impact protection.

Contact lens users: Switch to glasses during extended emergencies when water for lens hygiene is limited. Contaminated lenses cause serious infections.

Irrigation: Sterile saline or clean water for rinsing debris. Do not rub — flush.

Hearing

Chainsaw work, generator operation, and power tool use produce noise levels that cause permanent hearing damage in minutes without protection.

Noise levels: A chainsaw produces 90–110 dB. Permanent damage begins at 85 dB sustained. NIOSH recommends ear protection above 85 dB.3

Protection: Foam earplugs (NRR 30+) or earmuffs. Keep a pair with every chainsaw and generator. Hearing loss from cleanup work is permanent.

Daily maintenance checklist

Inspect both feet — hot spots, blisters, skin breakdown

Check and redress any open cuts or abrasions

Brush teeth — even with minimal water

Change socks if feet have been wet

Apply lotion to hands if cracking or dryness

Note any new pain before sleep — do not defer assessment
