How To Assess Sandstorm Severity Before Making Decisions?

Monitoring Wind Speed and Visibility

When assessing the severity of a sandstorm, wind speed is a crucial factor. A wind speed of 30-40 km/h is considered moderate, while wind speeds above 60 km/h are extremely hazardous. Monitor wind speed using a reliable anemometer or a mobile app that provides real-time wind speed data. Visibility is also essential, with a range of less than 100 meters indicating a high-risk situation. Use a dust meter or a visibility meter to measure the level of particulate matter and visibility.

Sand Particulate Count and Danger Levels

Sandstorms can be categorized based on the particulate matter count (PM10) in the air. A PM10 level of 500-1000 μg/m³ is moderate, while levels above 2000 μg/m³ are extremely hazardous. Use a particulate matter sensor or a portable air quality monitor to measure PM10 levels. This data will help you determine the severity of the sandstorm and make informed decisions. For example, if PM10 levels are above 2000 μg/m³, it may be necessary to take shelter immediately.

Sheltering and Evacuation Strategies

When sandstorm severity reaches extreme levels, sheltering and evacuation are essential. Identify a safe shelter with a solid roof and walls, such as a building or a vehicle with a hard top. If no such shelter is available, create a makeshift shelter using a tarpaulin or a space blanket. When evacuating, follow the wind direction to avoid being blown back into the storm. Stay low to the ground and avoid travel during the worst of the storm.
