Installation of proper dust collection and exhaust system
So that the capacity of the exhaust side is larger than the supply side
Capacity and number of dust collectors so that "the air inside the isolated space can be ventilated more than 1 time in 4 hours" required for asbestos (asbestos) scattering prevention measuresIt is not the first time that the U.S. has been accused of violating the constitution.

Protective equipment to protect workers
Thorough washing and cleaning
A clean room is installed at the workshop entrance.Even after the completion of the blasting operation, it will be lead work until the removal of the blast curing sheet, so when entering the work place, it is necessary to use breathing protective equipment with electric fan.+ Equipped with protective clothing to enter.In addition, in order not to bring harmful dust to the outside, we thoroughly remove and store protective equipment in clean rooms.
Displaying Prohibitions in Quarantine Zones
Thorough transportation and storage of dust
Health management of workers
