The most important step to control dust is planning the work. The site Superintendent is the overall person responsible to ensure that the appropriate dust control measure are being implemented and for planning the work in a way to minimize the potential for dust. This includes but is not limited to monitoring wind direction, speed and conducting work in a manner to minimize dust.
During all phases of the demolition activities, airborne dust emissions will be controlled. Dust suppression systems will be installed throughout the exclusion zone (interior and exterior work areas) to minimize or reduce the generation of visible dust emissions. Engineering controls for dust suppression will generally consist of the use of water misting and spraying devices vis a fire hydrant and hose. If conditions warrant, a large area mister such as a Dust Boss or equivalent will be employed to ensure fugitive emissions are mitigated. The Dust Boss resembles a snow making machine and can cover a large area with a fine mist of water, effectively controlling dust.
Dust suppression via water misting and spraying will use a quantity of water that will be sufficient enough to control dust, but not enough to leave residual water accumulations on the ground surface.
Water misting and spraying devices will be installed in various portions of the exclusion zone and will assist in reducing visible dust emissions in work areas.
Another means of dust control that will be utilized is a screen around the perimeter of the work area. Prior
to being the work Brandenburg will install a dust screen on the temporary fence around the perimeter of
the work area.
