Below is a summary of available MOSH dust practices for industry. Complete practice guides can be uploaded from the 'documents' folder.
This practice allows for immediate intervention when the continuous real-time monitoring system detects excessive airborne pollutant levels.
The installation of fogger/mist-spray systems to capture airborne respirable dust:
The wetting of footwalls and sidewalls with water and surfactants. Spray cars, drawn by a locomotive, spray the solution onto the foot and side walls so as to consolidate the dust and to prevent it becoming airborne.
The principle of multi-stage filtration system ensures that contaminated air is drawn/extracted by means of a fan through the filtration unit where it undergoes the following stages of filtration:
In principle, the winch cover simply involves fitting a cover to the winch drum guard or to the winch casing of existing winches thereby reducing winch operators' exposure to harmful dust.
