Reducing Noise Pollution in Demolition Projects

Reducing Noise Pollution in Demolition Projects

The noise and dust generated by demolition sites may disturb nearby residents. There are many strategies to deal with these issues which means that workers as well as homeowners can enjoy a pleasant environment.

Through filtering particles and pollutants inhaled, the local exhaust systems (LEVs) are able to help cut down on the noise generated during demolition and masonry works.

Sound Control for Demolition

There are numerous ways to reduce the noise and disruptions that demolition works cause. Working during daylight hours and the restriction of noise-producing machines to specific times can aid in reducing the noise.

Announcing to residents the schedule for demolition could let the residents know prior to demolition the expected timeframe. Also, identifying a contractor with a good compliance history can help reduce chances of complaints. Additionally, using equipment that is quieter could significantly lessen the amount of noise produced in demolition. In the case of Obayashi’s Bubble Silencer can cover the chisel of huge breakers (heavy machinery that crushes concrete) by using bubbles that cover dust and block out noise. The device reduces noise levels as high as 5 decibels and is able to capture 90% of dust produced during demolition.

Dust suppression in demolition

Removal of dust is a fundamental part of demolition, as dust can be contaminated with hazardous substances such asbestos, aluminium, and silicon crystals. These substances pose a risk to workers as well as neighbors.

In the beginning an area for demolition will be thoroughly watered down to prevent dust from being in the air. It’s a good method but it takes a substantial amount of work in order to move the hoses and continuously reposition them.

Other solutions, such as making use of a misting gun to collect dust is more reliable and safer for those working. A device like the Bubble Silencer can cover a breaking device and decrease noise by 5 dBA with bubbles. This helps to safeguard workers’ health.

Noise barriers absorb and block sound waves, which helps minimize noise from demolitions. They’re especially efficient if they are located near the noise source or in an area that is sensitive to noise.

Also, you can reduce pollution by using equipment to reduce noise as well as scheduling work during time periods that are peaceful. It is also important to check the level of noise regularly and then make any necessary adjustments.

The use of hydrodemolition equipment for instance, can dramatically decrease dust and noise in concrete demolition. Hydrodemolition hammers equipment don’t have to strike as hard at concrete as breakers used in traditional methods. The result is that they are quieter.

Dust Control for Construction

Dust is an unavoidable and a challenging complication of building projects, particularly during the drier months. Dust can be a nuisance to the workers involved, it poses serious health risk. The inhalation of dust regularly can result in respiratory ailments and even the death. If dust becomes airborne, it can be harmful to wildlife and biodiversity.

To reduce dust from construction teams may employ various measures to control dust. These can be broadly categorized as administrative controls, and personal protection equipment (PPE).

Engineering controls include the use of water sprays for dust suppression or installation local exhaust ventilation machines. Administrative controls include modifying the work schedule and limiting work that is dusty in its time and frequency. The last line of defense against dust is a PPE system, which includes eyewear and respiratory protection.

Environmental Control at the Deconstruction Site

When demolitions create a lot of noise and dust it’s essential to lessen impacts on the residents of the interest of complying with environmental laws. Utilizing a relocatable system of monitoring equipped with a noise and dust sensor, you are able to constantly monitor the quality of air and alter the environment on site in order to lessen the impact of pollution.

It is also recommended to work with an experienced contractor. This reduces the possibility of complaints coming from neighbors.

The research that has been conducted shows that pollution levels on demolition sites are usually not observed, and therefore cannot be analyzed in real time. This new IMS monitors air pollution, noise and vibration pollution in demolition locations to check they’re in line with government regulations.
