Dust storm safety is an essential topic for anyone who lives, works, or travels in areas where these powerful storms occur. These storms can roll in quickly, reducing visibility to nearly zero, creating dangerous driving conditions, and posing serious health risks.
Dust storms and haboobs can happen anywhere in the United States, but they are most common in the Southwest. Haboobs form when powerful thunderstorm outflow winds lift large amounts of dust into the air. These strong winds can quickly develop into a dust storm, creating dangerous conditions with drastically reduced visibility.
Dust Storm Watch vs. Warning
A dust storm watch indicates the areas and times when dust storms are likely to occur. It means you should stay alert and be prepared, as conditions are favorable for a dust storm to develop. A dust storm warning is issued when blowing dust reduces visibility to half a mile or less and wind speeds reach 30 mph or higher. It signals that you should take immediate action and follow safety precautions.
Driving Safety
Dust storms can strike with little warning, creating hazardous driving conditions. There are some safety practices to follow if a dust storm hits while driving, such as:
- Pull the vehicle over as far and as soon as possible, stop, turn the lights off, set the emergency brake, and take your foot off the brake pedal to ensure taillights are not illuminated
- Do not drive into a dust storm area, if possible
- And, if you cannot pull off the road, proceed at a speed suitable for visibility, turn lights on, and sound the horn occasionally. Use the lines on the road to help guide you and pull off the road when safe to do so
If dust storms are common in your area, check the weather forecast or local media for possible dust storm warnings prior to driving.
Dust Storms During Work
If a dust storm strikes while you’re on the jobsite, immediately move to the nearest shelter and follow these recommended safety practices:
- Close all windows, doors, and vents
- Turn off fans or air conditioning; in a vehicle, switch the air intake to “recirculate”
- Cover the mouth and nose with a N95 dust mask
- And, if you’re inside a vehicle, stay inside until the dust storm passes
If you find yourself outdoors with no nearby shelter or vehicle, get as low to the ground as you can. Stay away from trees and low-lying areas, as dust storms can bring strong winds and may be accompanied by thunderstorms or flash floods. Protect your face and any exposed skin, and if possible, cover your nose and mouth with an N95 dust mask.
Conclusion
Dust storms can develop quickly and pose serious risks to anyone caught outdoors or on the road. By staying informed, seeking shelter, protecting yourself, and following recommended safety practices, you can greatly reduce your risk during these dangerous events.
