Reducing Noise and Dust Impact in Demolition Projects

Noise and dust from demolition sites can disrupt neighbours. There are numerous strategies to deal with these issues, so both workers and homeowners can enjoy calm and peaceful surroundings.

LEV stands for local exhaust. (LEV) Systems can help reduce the noise of demolition or masonry construction through the filtering of dust and other pollutants which are inhaled.

Noise Control during Demolition

Demolition work is noisy and disruptive. However, there are options to limit noise levels to lessen the impact to nearby residents. Working during daylight hours and the restriction of noise-producing equipment to certain times will help reduce noise.

Informing residents about the timetable of the demolition process can help them be aware in advance of what they can expect. Contractors with experienced compliance records can aid in the reduction of complaints. In addition, using less noisy equipment will significantly reduce the amount of noise produced during demolition. Obayashi’s Bubble Silencer, for instance is a device that covers the chisel of massive breakers (heavy machines that crush cement) with bubbles to reduce the noise. The device reduces the level of noise by 5 dBA and contains 90% of dust produced during demolition.

Dust suppression in demolition

Dust suppression is an important element of demolition since dust particles may contain harmful material such as asbestos, crystal silica and aluminum. These materials are hazardous for workers and neighbors.

For dust control, a typical demolition site will be thoroughly sprayed with water before the work starts to dampen any dust and to prevent the dust from getting airborne. It is an effective method, but requires a large quantity of labour to move hoses as well as constantly moving the hoses.

Others, for instance making use of a misting gun to collect dust is more reliable and safer for the workers. Bubble Silencers are able to lower the noise from breakers by up to 5 decibels. It is beneficial to employees’ health.

Acoustic Barriers during Demolition

Noise barriers absorb or block the sound waves, and pha do nha xuong cu hcm can help reduce demolition noise pollution. These barriers are most effective when placed near the source of noise or a sensitive area.

Also, you can reduce sound by using equipment that reduces noise or scheduling work to time periods that are peaceful. In addition, it’s essential to check the level of noise regularly and make adjustments if necessary.

Hydrodemolition, for instance reduces noise and dust when removal of concrete. Hydrodemolition hammers equipment aren’t required to strike as hard at concrete as traditional breakers. The result is that they are quieter.

Dust Control in Construction

Dust is an inevitable however, it can be a difficult byproduct of building projects, particularly in the dry months. It not only irritates the workers but could also present an extremely health risk leading to lung problems and even death if inhaled frequently. Dust poses a risk for biodiversity and wildlife if it is inhaled and makes its way into rivers and streams.

Teams can use a number of methods to control dust that is generated during construction. They are categorized in three categories: engineering controls, administrative control, and personal protective equipment (PPE).

Controls in engineering include the application of water sprays to reduce dust or the installation of exhaust vents local to equipment. Administrative controls include modifying routines of work and also limiting duration and frequency for high dust-related activities. PPE is the ultimate line of defense against dust. It includes respiratory protection and eyewear.

Deconstruction Site Pollution Control

Though demolition operations generate significant amounts of dust and noise making it difficult to minimize the effects on the nearby inhabitants can ensure compliance with local laws on environmental protection. You can measure the condition of the air continuously and adapt your worksite accordingly using a portable monitoring system with a dust and noise sensor.

It’s equally important that you choose an individual contractor with experience working on similar tasks. This will help decrease the likelihood of complaints from your neighbours.

The research that has been conducted shows that dust and other pollutants that are emitted from demolition sites often aren’t tracked, which means they can’t be measured in real time. The latest IMS examines air pollution, noise and vibration pollution in demolition locations to check they comply with the regulations.
