Introduction

Dust storms and blowing dust are not just inconveniences - they are fast-moving hazards capable of reducing visibility to near zero, disrupting transportation, and creating serious health threats. Events such as haboobs in the Southwest can form and move rapidly, turning ordinary conditions into life-threatening emergencies within minutes.

The following guidance consolidates best practices from the National Weather Service, the American Lung Association, and federal emergency management agencies. Each recommendation is evidence-based and designed to reduce risk during and after dust events.

Hazard Types

Blowing Dust / Dust Storms / Haboobs
Powerful wind events that lift large amounts of dust and sand into the air. They can create sudden "whiteout" conditions on roadways, resulting in multi-vehicle collisions and stranded travelers.
Respiratory Health Threats
Dust particles irritate the eyes, throat, and lungs. They can trigger asthma attacks, worsen bronchitis, and cause allergic reactions. Even healthy individuals may experience coughing or shortness of breath.
Property and Vehicle Damage
Dust infiltration can clog vehicle air filters, damage HVAC systems, and coat electronics and mechanical equipment. Long-term exposure can increase maintenance costs and reduce lifespan of machinery.
Power Outages, Fires, and Secondary Hazards
Dust storms are often associated with strong winds. These can topple power lines, spark wildfires, and compound other ongoing disasters.

Preparation

Before the event

  • Monitor official forecasts and alerts for Dust Storm Watches and Warnings. A watch means prepare; a warning means take immediate protective action.

  • Prepare your home: seal windows and doors, turn off air conditioning to prevent infiltration, and secure outdoor items.

  • Stock protective gear: N95 or better masks, airtight goggles, and blankets for emergency shelter.

  • For those with asthma or heart/lung conditions: create an action plan and ensure inhalers or necessary medication are accessible.

  • Identify safe indoor shelter locations away from windows and doors.

Checklist essentials

Battery-powered radio for weather alerts
N95 or higher-rated masks, airtight goggles
Water supply to prevent dehydration
Blankets, flashlights, and first aid kit
Emergency contact list and medical information
Vehicle kit: mask, goggles, blanket, water, phone charger, and brush for clearing dust buildup

During the event

  • Indoors: Close all windows, doors, and vents. Turn off air conditioning and use an air purifier if available. Keep pets inside.

  • Outdoors: Use protective equipment—cover mouth and nose with an N95 mask or damp cloth, wear airtight goggles, and avoid exertion.

  • Driving: Do not attempt to drive through a dust storm. Pull completely off the road, turn off all vehicle lights, keep seatbelts fastened, and wait until visibility improves. “Pull Aside, Stay Alive.”

  • Health Conditions: Individuals with asthma should follow their action plans and use prescribed inhalers. Avoid activities that stir up additional dust indoors.

  • Continuously monitor weather and air quality alerts.

After the event

  • Remain cautious—dust can stay suspended in the air for hours.

  • Clean home surfaces with damp cloths or mops (not dry sweeping).

  • Inspect and replace filters in vehicles, HVAC systems, and air purifiers.

  • Wash down exterior property to remove settled dust.

  • Monitor for respiratory symptoms such as persistent cough or difficulty breathing; seek medical care if severe.

  • Document property damage and review insurance coverage.

Special Populations

Children

Keep children indoors during dust events. Provide masks and goggles for older children if going outside is unavoidable.

Older Adults

Older adults face higher risk of respiratory distress. Check in frequently and ensure access to water and medications.

People with Disabilities / Medical Needs

Maintain sufficient supplies of medication, oxygen, and air filters. Prioritize safe indoor environments.

Businesses

Secure outdoor materials and equipment. Suspend outdoor work if visibility drops or health hazards increase. Provide respiratory protection for employees.

Pets

Bring animals indoors. Cover food and water dishes. After exposure, rinse eyes and nose with clean water.

Quick Reference Tables

Dust Hazard Response by Alert Level
Alert Level Message Actions
Watch / Advisory Be prepared Close buildings, secure items, check emergency supplies
Warning (Active) Act immediately Move indoors, stop driving, use masks and goggles
Post-Storm Hazards linger Clean surfaces, replace filters, monitor health

Driving Protocol: “Pull Aside, Stay Alive.” Pull off safely, turn off lights, set brake, remain inside vehicle until conditions improve.

Additional notes/thoughts

Before the next dust event, ask:

  • Who in your household is most at risk—children, elders, or those with chronic conditions?

  • Are protective masks, goggles, and medications readily accessible?

  • Can your home and vehicle be sealed quickly against dust intrusion?

  • Do you have accurate, real-time access to weather alerts?

  • Have you practiced your response plan for home, work, and travel?

Dust storms develop fast and often without warning. Preparation and rapid action are essential for protecting lives, health, and property.
