When it comes to demolition projects, health and safety are kept as the top priority, at all times.
This is balanced against other key qualities, including efficiency and practicality.
Dust suppression brings all of these qualities to a project – increasing its health and safety standards, while allowing operatives to complete the demolition tasks more efficiently and practically.
Below, we’ve shared a comprehensive guide to dust suppression in demolition, including a definition and explanation of why it is used, and a full breakdown of the benefits that it brings to demolition projects.
What is dust suppression?
Dust suppression is a professional method of controlling and reducing the dust that is generated during a demolition.
In any demolition project – but particularly when concrete or brickwork are involved – high volumes of dust can be generated. If not contained or reduced, then these dust particles can cause a significant health and environmental hazard.
So, by implementing dust suppression methods, project managers can minimise this hazard, and ensure full compliance with all associated regulations.
Why is dust suppression used in demolition?
The dust created by a demolition project can contain a variety of substances (including silica and asbestos) that are hazardous or toxic to humans.
As a result, dust suppression is used in demolition to:
- Reduce project teams’ exposure to harmful substances
- Protect site visitors, residents and other people in the area from being exposed to these substances
- Ensure the project has minimal impact on the area’s air quality
- Maintain regulatory compliance
- Adhere to high health and safety standards
- Improve visibility for workers, allowing them to complete their jobs more safely and accurately
What types of demolition projects most commonly use dust suppression?
Not all demolition projects require dust suppression techniques. This is because not all projects generate a high enough volume of dust – or the dust that they do generate is not hazardous – for this approach to be necessary.
The project types that most commonly require dust suppression include:
- Concrete demolitions
- Brickwork demolitions
- Demolition of commercial properties (such as retail sites or offices, for example)
- Demolition of industrial properties (such as warehouses or manufacturing sites, for example)
The main dust suppression methods
The most common method of dust suppression is water suppression.
This involves spraying water onto the site as the demolition occurs, so that the dust is dampened (thereby preventing it from becoming airborne).
This can be achieved through water sprays, high-pressure misting systems, or even manual or automated hoses.
Alternatively, other common dust suppression techniques include:
- Foam suppression – For which a biodegradable foam solution is added to the site before the demolition takes place, to hold dust particles in place.
- Physical barriers – such as dust screens or windbreaks, positioned around a demolition site.
- High-powered extraction systems – These can be used in an indoor demolition, to remove dust from the area.
Whichever method you choose, you and your team must adhere to all relevant health and safety measures. Preparatory site planning and proper containment plans are imperative, and regular air quality monitoring must be conducted throughout the project. Furthermore, even with dust suppression techniques in place, your workers must wear suitable PPE at all times.
