Dust and noise from demolition sites can disturb neighbors. There are however efficient ways to deal with this issue so that residents and workers can enjoy a comfortable working environment.
Through filtering dirt and other pollutants that are inhaled the local exhaust systems (LEVs) will help to reduce the sound level during demolition or construction works.
The Control of Noise in Demolition
There are many methods to minimize the sound and disturbance that demolition works cause. You should avoid working during daylight hours. restriction of the use of loud equipment to certain hours will aid in reducing the amount of noise.
Informing residents about the dates for demolition could let them be aware in advance about what is to be expected. Furthermore, selecting contractors with a strong record of compliance can reduce the likelihood of complaints. Finally, the use of more quiet equipment can reduce the sound levels in demolition. Like Obayashi’s Bubble Silencer is a device that covers the chisel in giant breakers (heavy equipment that crushes concrete) by putting bubbles on top to absorb dust and block out noise. The device reduces the noise level by 5 dBA and contains 90% of dust generated by demolition.
The suppression of dust in demolition
Dust control is an essential part of demolition, as dust particles can contain hazardous substance like asbestos crystal silica and aluminum. Inhaling these materials could cause harm to workers as well as the residents who live nearby.
To control dust the typical demolition site is sprayed thoroughly with water before the work starts to dampen any loose material and prevent the dust from getting airborne. This is a very effective technique however, it does require a considerable quantity of labour to move the hoses around and to constantly move the hoses.
Some other options, such as using a misting cannon to collect dust can be more effective and safe for the workers. The Bubble Silencer can cover a breaker and cut the noise to 5 decibels using bubbles. This helps to safeguard workers’ health.
Acoustic Barriers for Demolition
Noise barriers absorb or block the sound waves, and can help reduce the impact of demolition noise. They are the most effective when placed near the source of noise or within a sensitive area.
Other options to lessen the noise are to use equipment that has noise-reducing attachments and scheduling tasks during times when others are not present. It’s essential to constantly check the level of noise and modify if necessary.
Hydrodemolition for example, can reduce dust and noise while taking concrete away. Hammers that use it don’t need to strike pha do nha tai Binh Tan as hard at the concrete like they would using traditional breakers, which makes the noise less.
Dust Control Methods for Construction
Construction projects are inevitably contaminated by dust, which is a concern during dry months. Dust not only causes irritation to workers but can also pose a serious health risk, leading to lung problems and even death when inhaled regularly. Dust could also pose a threat for biodiversity and wildlife if it becomes airborne and makes it into waterways.
Teams may employ a variety of methods to control dust during construction. They can be grouped as engineering controls, administrative control and personal protective gear (PPE).
Controls in engineering include the application of water sprays for dust control or the installation of exhaust vents local to machines. Administrative controls include modifying the working schedule, and also limiting those activities that are high in dust length and frequency. PPE is the ultimate line protection against dust. It also includes eyewear and respiratory protection.
Demolition Site Pollution Control
Although demolition projects generate lots of dust and sound, it’s essential to lessen the effect on residents in the interest of complying with environmental laws. Utilizing a relocatable system of monitoring using a noise or dust sensor, you will be able to continuously assess the air quality and then adjust the working area to minimize the amount of pollution.
It’s also essential that you choose a contractor who has demonstrated previous experience in similar assignments. This reduces the likelihood that your neighbour will complain.
Existing research reveals that environmental pollutants on demolition sites are not often monitored, and thus cannot be measured at a real-time rate. The new IMS examines air pollution, noise and vibration pollution in demolition sites to make sure it is in compliance with all regulations.
