4. Dust
▶ Dust is a collection of microscopic particles of material.
▶ Dust is heavy enough to see and light enough to be carried by the wind.
▶ Dust can be made up of pollen, bacteria, smoke, ash, salt crystals from
the ocean, and small bits of dirt or rock, including sand.

5. Dust Emission
▶ Construction activities can generate a large amount of dust that can
cause significant impacts on air quality of surrounding areas.
▶ Dust emission originate from onsite activities such as bulk material
transportation, loading and unloading, and the movement of
vehicles and equipment.
▶ Construction dust forms a nuisance to site workers, has adverse off-
site impacts on local communities and is harmful to health

6. Dust Generating Activities
▶ Vehicular movement over unsealed roads
▶ Mechanical interaction with site surfaces during grading and excavation
▶ Loading / unloading / haulage of granulated construction materials such
as soil, sand, rock, fill
▶ Stockpiling, handling and use of powered construction materials such
as cement

12. Dust impact on Human Health
Dust particles small enough to be inhaled may lead to:
▶ Irritation of the eyes
▶ Coughing
▶ Sneezing
▶ Hay fever
▶ Asthma attacks.

13. Control Measures
▶ Phase construction activities
▶ Consider applying materials and surfaces that aide dust suppression
▶ Minimize* on windy days
▶ Temporary access and haul roads shall be clearly demarcated,
graded a stabilized, and capped with suitable materials (crushed
asphalt, gravel, etc.)
▶ Vehicle speeds shall be regulated to 30km/h
▶ Water suppression
▶ Water cannons and/or misting systems
▶ Point-source dust –vacuum collection systems
