The NHSRCL has been successfully using mist guns on sites to catch all escaping dust particles and curb air pollution in Mumbai

Besides the project sites, the mist gun will also be used on adjoining streets too, an official said

“In addition, the raw material and waste material has been enclosed with tarpaulin and green net to avoid dust emissions," an official said

"The dumpers carrying material are ensured to be closed with tarpaulin so that no dust is emitted while travelling,” a senior NHSRCL official said

A wheel wash facility is provided at site, which cleans the wheels of the vehicles, thereby avoiding the vehicles to carry dust through their tyres/wheels in and out of the site, the official said

Close monitoring is carried out by installing of CCTV camera. Manual brooming of internal and adjacent roads and collection of dust, the official added

“Water sprinkling using tankers is also being done three times a day and the frequency of water sprinkling increases as and when required. Constant air monitoring is carried out on site to monitor the pollutant levels. All the workers and staff are made mandatory usage of PPE as per the site conditions and assigned work,” the official further added
