Demolition sites are a source for dust and noise, which can be disruptive to nearby residents. However, there are many methods to control these nuisances so that both employees and the residents are able to enjoy a the comfort of their workplace.
By filtering the dust and contaminants inhaled, LEVs can help reduce noise pollution. (LEVs) will help to reduce the sound level during demolition or masonry works.
Noise Control in Demolition
There are many methods to reduce the noise and disruptions that demolition works cause. When you work during daylight hours, and restriction of the use of loud equipment during certain times of the day will aid in reducing sound.
Informing residents about the dates for demolition could let people know ahead of time about what is to be expected. A contractor who has an established track record of compliance may aid in the reduction of complaints. In addition, using less noisy equipment will significantly reduce the noise generated when demolition. For example, Obayashi’s Bubble Silencer can cover the chisel of huge breakers (heavy equipment which crushes concrete) with bubbles in order to block the noise and minimize dust. The device reduces noise levels by up to 5 dBA and is able to capture 90% of dust generated in demolition.
Dust Control in Demolition
Dust removal is an important aspect of demolition because dust particles may contain harmful substance like asbestos aluminum, and crystalline silica. These are dangerous for both workers and nearby residents.
For dust control on demolition sites, the area is sprayed thoroughly with water before the work starts to dampen any particles and keep it from becoming airborne. This is a very effective technique however it requires a significant quantity of labour in order to move the hoses and continuously reposition the hoses.
Alternative solutions, like using a misting cannon to catch dust are more efficient and safer for workers. Bubble Silencers are able to lower the noise from breakers up to 5dBA. It is beneficial to the health of workers.
Acoustic Barriers to Demolition
Noise barriers reduce or block the sounds and reduce demolition noise pollution. The most effective noise barriers can be found in areas that are near to the source of noise, or in a sensitive area.
It is also possible to reduce background noise using noise-reducing equipment or scheduling work to periods of quiet. It is also important to monitor noise levels regularly and adjust as needed.
Utilizing hydrodemolition tools, for instance, can dramatically decrease dust and noise in demolition of concrete. The hammers do not have to smash hard into the concrete as they do with traditional breakers, making them quieter.
Dust Control Strategies for Construction
Construction sites are always polluted by dust. It could be an issue especially during the dry season. It not only irritates construction workers, but it can also be an important health risk leading to lung problems and even death when inhaled regularly. When dust is inhaled, it may ep cu thep mong tang ham be hazardous to the wildlife and biodiversity.
To minimize construction dust Teams can use various measures to control dust. They are classified as engineering controls, administrative control and personal protective equipment (PPE).
Engineering controls include the use of water sprays to control dust, or the setting up of local exhaust ventilation on machines. Administrative controls may involve changing working schedules, and restricting the duration and frequency for high dust-related activities. One of the best defenses against dust is PPE, that includes respiratory and eye protection.
Deconstruction Site Pollution Control
As demolition work generates a lot of noise and dust it’s crucial to limit the impact on people living nearby in order to comply with environmental laws. With a monitoring device that is relocatable with a dust and noise sensor, you will be able to continuously evaluate the quality of the air and make adjustments on the worksite to minimize pollution.
It is also important that you choose an individual contractor with previous experience in similar project. This will decrease the chance that your neighbour will complain.
Current research shows that dust and other pollutants that are emitted from demolition sites are not often controlled, so they cannot be analyzed in real time. The brand new IMS is specifically designed to track noise, air and vibration pollutants on demolition sites in order to make sure that they conform to the requirements of regulations.
