Concord: Ash/Debris Cleanup Advisory


Last updated: April 24, 2018, 9:41 am

The large structure fire in Concord consisted primarily of construction materials (predominately wood). Residents should avoid direct contact and inhalation of ash/debris that was produced by the fire. Residents may use a mild soap and water to clean up ash/debris. To minimize dust generation, residents should consider lightly dampening ash/debris prior to commencing sweeping activities. Swept up ash/debris may be placed in a standard household trash receptacle. Any towels or cleaning materials should be rinsed in a sink that drains to a sanitation sewer. Residents should avoid washing or sweeping ash/debris into storm drains, as this will result in pollution accumulating in nearby creeks and rivers.
