Protecting People During Demolition Projects

Demolition is the planned process of safely tearing down buildings, structures or parts of structures using manual, mechanical, or controlled methods. It includes everything from soft‑strip and internal removal to full structural demolition. The goal is to remove built assets safely while managing risks such as dust, noise, vibration, and hazardous materials.

Demolition projects are necessary when structures are unsafe, outdated, structurally unsound, or no longer fit for purpose. They’re also required to:

• Prepare sites for new construction or redevelopment
• Remove fire‑damaged or contaminated buildings
• Upgrade infrastructure such as roads, rail, utilities, and water facilities
• Improve safety by eliminating unstable structures
• Support regeneration and urban improvement programmes

Common types of demolition include:

• Manual demolition - Hand tools used for small‑scale or interior work
• Mechanical demolition - Excavators, breakers, and high‑reach machines
• Controlled demolition - Explosives used to bring down large structures quickly
• Soft strip - Removal of non‑structural elements before main demolition
• Selective demolition - Targeted removal for refurbishment or partial rebuilds
• Industrial and specialist demolition - Factories, plants, towers, bridges, marine or defence structures

The main health hazards workers and the public are exposed to include:

• Dust (silica, wood dust, insulation fibres)
• Asbestos and other hazardous materials
• Fumes from cutting, burning, plant and equipment
• Noise and vibration affecting long‑term health
• Manual handling injuries
• Structural collapse or falling debris
• Contaminants such as lead paint, bird guano, fuels, and chemicals

Effective planning and engineering controls such as dust suppression, ventilation, extraction, and monitoring are critical - speak with a technical consultant today to see how RVT Group can help support your risk management strategy.

Demolition projects use a mix of heavy machinery and safety equipment. Typical tools include excavators, breakers, crushers, telehandlers, and dust‑suppression systems.

Sites rely on temporary specialist hazard control equipment supplied by RVT Group whilst demolition takes place, including:

• Dust suppression units
• Dust and fume extraction and LEV systems
• Ventilation and filtration for internal soft‑strip work
• Noise control barriers and acoustic screens
• Real‑time dust, noise and vibration monitoring
• Water treatment and silt control equipment

Yes. Weather conditions directly affect demolition safety and environmental control so seasonal planning ensures hazard management plans remain effective.

Summer considerations:

• Higher dust levels due to dry conditions
• Risk of overheating for workers
• Greater need for continuous misting and dust suppression
• More airborne hazards as materials dry out

Winter considerations:

• Slippery surfaces from rain, snow, and ice
• Reduced visibility and fewer daylight hours
• Poorer equipment performance in low temperatures
• Higher risk of structural instability from wind and storms

Key UK legislation and guidance for demolition includes:

• Construction (Design and Management) Regulations 2015 (CDM 2015)
• Control of Substances Hazardous to Health (COSHH) Regulations 2002
• Control of Asbestos Regulations 2012
• Work at Height Regulations 2005
• Management of Health and Safety at Work Regulations 1999
• HSE guidance (HSG168, HSG53, HSG247, etc.)
• BS 6187 - Code of practice for demolition

Every demolition project requires a pre‑construction plan, risk assessments, and method statements to meet these legal obligations. RVT Group can help recommend solutions to help minimise risk.

The best dust suppression depends on the size of the site, material type, and weather, but common effective methods include:

• Misting systems (fine atomised mist captures airborne particles quickly)
• Water cannons and fogging units
• Hose lines for smaller areas
• Demolition‑integrated suppression (e.g. excavator‑mounted spray bars)
• Encapsulation for soft‑strip or internal works
• Foam‑based suppression for stubborn dust like silica or plasterboard

Misting is generally the most efficient because the droplets match the size of dust particles and bind them effectively.

Measuring hazards is essential for compliance and worker safety. Common monitoring methods include:

• Dust monitoring (PM10, PM2.5, respirable crystalline silica)
• Noise monitoring to check exposure limits
• Vibration monitoring for HAVS and structural impact
• Gas and fume detection for confined spaces or hot works
• Air quality sensors placed around the boundary
• Personal exposure monitoring worn by workers

Live, real‑time monitoring paired with data logging gives the best insights and supports HSE compliance.

Engineering controls should be positioned as close to the dust or fume source as safely possible. General best practice:

• Ventilation, extraction, and local dust control: 0.5 - 2 metres from the source
• Misting units or fog cannons: 5 - 20 metres depending on wind, site layout, and throw range
• Boundary monitors: Placed at site perimeters, especially near receptors such as footpaths, homes, rail, watercourses, or other sensitive areas

RVT Group offer free site assessments to help advise you on what hazard controls would work best during your current and future stages of your demolition project.
