What Is Typically the Easiest and Most Effective Dust Control Measure?

Justin Rollin

Dust control is an important aspect of maintaining healthy environments and safe working conditions across a variety of industries. From construction sites and unpaved roads to mining operations and agricultural fields, dust emissions impact air quality, visibility, and public health. 

If you’re looking to effectively manage dust, you’ll first need to understand the different methods available and then choose the most suitable option based on your property’s specific needs and environmental conditions. 

In this guide, we’ll cover the dust control products that our team at Ninja De-Icer stands by and explain application methods, so you can choose the right approach to suit your needs.

Understanding Dust and Its Implications

Dust is comprised of fine particles of solid matter, often generated through various activities such as construction, mining, agriculture, and vehicle movement on unpaved roads. These dust particles, particularly fine particles less than 10 micrometers in diameter (PM10), can remain airborne for extended periods, posing inhalation risks and contributing to respiratory problems, allergies, and other health issues.

Several Factors Influence Dust Generation

  • Soil type: Untreated soils with a higher content of fine material, like silt and clay, tend to produce more dust.
  • Weather conditions: Dry and windy conditions exacerbate dust emissions.
  • Traffic volume and speed: Higher traffic volume and speed on unpaved roads lead to increased dust generation.
  • Construction activities: Activities like excavation, grading, and material handling generate significant dust.

Effective Dust Control Measures: Choosing the Right Method

Numerous dust control methods are available, each with its advantages and limitations. Selecting the most suitable approach depends on several factors which we are going to consider further.

Water Spreading

This is a simple and widely used method involving spreading water on unpaved roads and other surfaces to suppress dust. While effective, its practical duration is limited due to evaporation, requiring frequent reapplication.

Calcium Chloride

Calcium chloride is a hygroscopic salt that excels at attracting and retaining moisture from the air. This characteristic makes it an effective dust suppressant as it increases the surface moisture content, preventing dust particles from becoming airborne. Calcium chloride is available in both liquid and granular forms, offering flexibility in application methods.


Magnesium Chloride

Magnesium chloride is another hygroscopic salt renowned for its dust suppression capabilities. Similar to calcium chloride, it attracts moisture from the air, keeping surfaces damp and preventing dust from becoming airborne. Magnesium chloride is also available in liquid and granular forms, offering versatility in application.


Synthetic Polymer Products

These products act as dust palliatives, binding particles together and forming a thin layer on the road surface to prevent dust generation. They offer extended control compared to water and salts, especially on high-traffic unpaved roads.

Cutback Asphalt

Applying a thin layer of cutback asphalt provides a more durable dust control solution, especially for heavily trafficked areas. However, it's a more expensive option and may have environmental considerations.

Additional Dust Control Strategies

  • Vegetation and ground cover: Establishing vegetation along roadsides and in exposed areas can effectively reduce wind erosion and dust generation.
  • Speed reduction: Implementing speed limits on unpaved roads helps minimize dust creation by vehicles.
  • Traffic management: Controlling traffic flow and minimizing congestion can reduce dust emissions in construction zones and other high-traffic areas.
  • Dust collection systems: Equipment with HEPA filters can be used to collect dust at its source, particularly in industrial settings with significant dust generation.

Make the Right Choice for Your Needs

Several factors influence the choice of the most effective and easiest dust control measure:

  • Project scale and budget: Water spreading might be suitable for smaller projects with limited budgets, while larger projects or those requiring long-term control may benefit from calcium chloride, magnesium chloride, or dust suppressant products.
  • Environmental considerations: If minimizing environmental impact is a priority, magnesium chloride or other eco-friendly dust palliatives might be preferred.
  • Application method: Consider the available equipment and resources for applying the chosen dust control solution.
  • Desired duration of control: Water requires frequent reapplication, while salts and dust suppressants offer longer-lasting control.

Why Calcium Chloride & Magnesium Chloride Are Excellent Choices for Dust Control

While various dust control methods exist, calcium chloride and magnesium chloride stand out as the most effective options, particularly for unpaved roads, construction sites, and other areas with significant dust generation. They’re hygroscopic, meaning they attract and retain moisture from the air, making them ideal for dust suppression. This characteristic allows them to maintain a higher water content on the surface, preventing dust particles from becoming airborne and effectively controlling dust emissions.

Benefits of Calcium Chloride and Magnesium Chloride

  • Longer-lasting dust suppression: Compared to simply spreading water, which evaporates quickly, calcium chloride and magnesium chloride provide extended dust control due to their ability to retain moisture. This reduces the frequency of reapplication, saving time and resources.
  • Versatility: Both calcium chloride and magnesium chloride are available in various forms, including granular and liquid solutions, making them suitable for diverse application methods and project needs.
  • Effectiveness on various soil types: They work effectively on a wide range of soils, including those with higher clay and silt content, which generally produce more dust.
  • Reduced maintenance costs: These salts help minimize dust-related issues such as equipment wear and tear, reduced visibility, and the need for frequent cleaning.

Choosing Between Calcium Chloride and Magnesium Chloride

While both are effective dust suppressants, there are some key differences to consider:

  • Environmental impact: Magnesium chloride is often considered more environmentally friendly as it is less corrosive to metals and poses a lower risk to vegetation.
  • Cost: Calcium chloride is typically more readily available and may be slightly less expensive than magnesium chloride.

Best Practices for Effective Dust Control

To ensure optimal dust control, consider the following best practices:

  • Regular monitoring: Monitor dust levels regularly to assess the effectiveness of control measures and identify areas requiring improvement.
  • Proactive approach: Implement dust control measures before dust generation becomes a significant problem.
  • Tailored solutions: Choose dust control methods based on the specific dust source, soil conditions, and project requirements.
  • Proper application: Follow recommended application rates and techniques to ensure optimal performance of dust control products.
  • Environmental responsibility: Choose environmentally friendly dust control solutions whenever possible.
  • Weather factors: Rainfall eventually removes salts from the treated surface, necessitating reapplication. Consideration of weather conditions and rainfall patterns is essential for planning application schedules and ensuring ongoing dust control.
  • Community engagement: Communicate with nearby residents and businesses about dust control efforts to address concerns and build positive relationships.

The Impact of Uncontrolled Dust

Failing to implement effective dust control measures can lead to several adverse consequences:
