Effective Noise and Dust Control Measures in Demolition
The noise and dust generated by demolition sites can disturb nearby residents. There are numerous methods to manage these noises for both residents and workers, so that residents can work in a pleasant environment.
LEV stands for local exhaust. (LEV) Systems can help reduce the sound generated from demolition or masonry construction through the filtering of dust and other contaminants that can be inhaled.
Sound Control to Demolish
There are numerous ways to reduce the noise and disruption from demolition activities. The use of daylight hours during work and restricting the use machines to specific times can aid in reducing sound.
Similar to announcing the schedule of demolition to local residents can let them know in advance about the expected disruptions. An experienced contractor with an established track record of compliance may assist in reducing complaints. In addition, using less noisy equipment could significantly lessen the amount of noise created during demolition. Like Obayashi’s Bubble Silencer covers the chisel of giant breakers (heavy machines that crush concrete) with bubbles in order to block dust and block out noise. It can reduce noise up to 5 decibels, and captures 90% of dust created during demolition.

The suppression of dust is an essential component of demolition work, since dust can be contaminated with hazardous substances like asbestos, aluminum, and silicon crystals. These are dangerous to both the workers and neighbors.
To reduce dust on demolition sites, the area is sprayed thoroughly with water prior to the start of work to dampen down any particles and keep it from becoming airborne. This technique is efficient, but it takes a lot of manpower in order to continually move around sites and reposition water hoses.
Others, for instance the use of a misting cannon in order to catch dust can be more effective and safe for workers. Bubble Silencers are able to lower the noise from breakers up to 5dBA. It is beneficial to the workers’ health.
Acoustic Barriers in Demolition
Noise barriers block the sound waves, and can help reduce the impact of demolition noise. They’re especially efficient if they’re located close to the sound source or a noise-sensitive area.
You can also reduce the sound by using equipment that reduces noise and scheduling your work around times that are quiet. It’s essential to constantly evaluate the noise level and adjust if needed.
Hydrodemolition is one example. It reduces noise and dust when removal of concrete. Its hammers don’t have to be pounding hard on the concrete like they would with traditional breakers, making them quieter.
Dust Control for Construction
Dust is a normal yet challenging side-effect from construction work, particularly during the dry season. It is not just irritating for workers but can also pose serious health risks, producing lung-related problems, and possibly death if breathed in frequently. Dust can also be dangerous for wildlife and biodiversity if it becomes airborne and makes its way into the waterways.
To reduce dust from construction Teams may use a variety of control measures. They could be classified as administrative control and personal protection equipment (PPE).
Engineering controls include using sprays of water to reduce dust or setting up local exhaust systems for machinery. Administrative controls can involve modifying work schedules and limiting duration and frequency of activities that generate high levels of dust. Last defense against dust is PPE which is eyewear and respiratory protection.
Deconstruction Site Pollution Control
As demolition work generates a lot of sound and dust, it’s important to reduce the impact on people living nearby in the interest of complying with environmental laws. The ability to measure air quality continuously and adjust your site accordingly with a portable monitor that includes a dust and noise sensor.
Additionally, it is recommended that you employ a reputable contractor. This helps reduce the chance of complaining from neighbors.
Current research shows that environmental pollutants on demolition sites are usually not monitored, and thus cannot be measured at a real-time rate. This new IMS is a monitoring system for air pollution and noise, and vibrations in demolition locations to check they are in compliance with regulations.
