Follow these tips for dust suppression on the jobsite
Blowing dust at jobsites can be a health and safety hazard to workers. What makes it worse is that employers tend not to be proactive about implementing controls to suppress airborne dust until it’s already a nuisance to workers.
Forecasts and temperature
Many jobsites review weather forecasts to schedule work for the week and these forecasts can determine if dust suppression is necessary on the jobsite.
If the outdoor temperature is high, the moisture in the soil begins to evaporate, causing it to dry out. It doesn’t take much wind to create a dust cloud. Workers should use water to suppress the airborne dust on the jobsite.
Wet method
The size of the project will determine what resources to use. For instance, on larger jobs, use a pick-up truck to pull a water trailer to spread water evenly on the ground. On smaller jobs, a bug sprayer may be adequate to keep the soil wet.
Establish periodic intervals to wet down the ground before it dries out. Depending on the source of the dust, workers may need to wear face coverings or respiratory protection.
For instance, if workers are near a coal pile, the coal dust can become airborne and expose workers to lead, arsenic, and mercury. Some workers may have medical issues, like asthma, making them more sensitive to specific dust exposures. Soil can also have contaminants that are hazardous to workers’ health.
Many jobs rely on the wind’s direction to determine their work positioning and location. This practice isn’t efficient. The wind is constantly shifting. Even small, occasional exposures can be hazardous to workers’ health because of changing wind direction.
The benefits of proper dust suppression extend beyond the jobsite. The surrounding community will appreciate these efforts and will highlight the company’s environmental stewardship.
Key to remember: Employers must to plan for their dust suppression needs on the project. Use weather forecasts to help predict when dust suppression is required.
