Chemical Dust Suppression

Chemical Dust Suppression

Chemical dust suppressants are commercially available for use on many types of emission sources. The performance of a product depends on many factors: ·

Application method and rate. ·

Surface moisture content during application. ·

Hydrological conditions, like site precipitation and drainage. ·

Mechanical stability of the surface aggregate. ·

 Percent of fines in the aggregate mix. ·

Structure of the base and subgrade.

Keep in mind that most of the products designed for trafficked areas are primarily intended for medium-traffic, low cost roads, that are typically surfaced with gravel. Dust suppression and periodic unpaved road maintenance are normally combined. For unpaved road applications, products applied and mixed into the road surface usually work better than if simply applied to the surface.

Evaluate available products against your own specific emission source, site, performance, and cost criteria. Review the manufacturer’s product literature, safety data sheet (SDS), and instructions before purchase and prior to use. Consider the risk to human health or the environment from hazardous characteristics of product ingredients, application practices, and the environmental characteristics of the site.

Be aware that during preparation or application, chemical dust suppressants may exhibit hazardous characteristics such as corrosivity or ignitability. Some products may produce excessive heat when mixed with water. Others may contain toxic or carcinogenic ingredients or contaminants. Observe all safety precautions and follow the manufacturer’s directions when handling, mixing, and applying chemical suppressants.

Any suppressant product or its ingredients may migrate from a treated site due to carelessness in application, runoff, leaching, volatility, dusting, or adhesion to vehicles. In areas where surface water or groundwater is nearby and where stream flow rates are low, adverse environmental impacts are possible. The burden of proof for product safety lies with the chemical manufacturers, distributors and users. Ask the vendor whether their product has characteristics or meets criteria that would cause it to designate as a Washington State dangerous waste as it is applied to the ground, after drying or curing, or as a result of biochemical decay. Washington’s Globally Harmonized System for Hazard Communication (Chapter 296-901, WAC) requires chemical manufacturers to obtain or develop an SDS for each hazardous chemical they produce. All employers must have an SDS at the workplace for each hazardous chemical they use.

Do not use undocumented material for dust control. All legitimate products have manufacturer product literature and an SDS that describe the product’s ingredients, characteristics, recommended use, safety practices, and limitations of use. If Ecological information (SDS Section 12) is not provided on the SDS, obtain and review this information from the manufacturer before making a purchasing decision.
