Demolition generates large volumes of airborne dust including respirable crystalline silica, concrete dust, and potentially asbestos fibres. Uncontrolled dust exposure causes silicosis, chronic obstructive pulmonary disease, and lung cancer. Effective suppression during demolition protects both workers and the surrounding community. This talk covers the dust control methods required during demolition activities on UK sites.
Key Hazards
Silicosis and lung disease from inhaling respirable crystalline silica
Asbestos fibre release from unidentified materials during demolition
Reduced visibility creating struck-by risks near operating plant
Community complaints and enforcement from excessive dust emissions
Control Measures
Complete the pre-demolition asbestos survey and remove all identified ACMs before demolition starts.
Use continuous water suppression on the demolition face using mist cannons or hose sprays.
Fit dust suppression attachments to hydraulic breakers and crushing equipment.
Erect solid hoarding and dust screens around the demolition area perimeter.
Provide RPE with a minimum APF of 20 for all operatives in the dust zone.
Monitor dust levels at the site boundary using real-time particulate monitors.
Damp down access routes and debris stockpiles regularly throughout the working day.
Stop demolition work if wind conditions are causing uncontrollable dust dispersion off site.
Brief all operatives on the dust management plan and their personal protection requirements.
Remember
All asbestos must be removed before demolition work starts on any structure
Use continuous water suppression on every demolition face throughout the operation
Wear RPE with a minimum assigned protection factor of 20 in the dust zone
Monitor dust levels at the site boundary and stop work if limits are exceeded
Damp down all access routes and debris stockpiles regularly throughout the day
