How much do you know about the concrete floor polisher machine? In this paper, according to the different physical properties of each component of the concrete floor polisher machine,using walk-behind milling machines and floor polishers on concrete or other silica-containing materials can generate respirable crystalline silica dust. When inhaled, the small particles of silica can irreversibly damage the lungs. This fact sheet describes dust controls that can be used to minimize the amount of airborne dust when using the concrete floor polisher machine.
Two methods for controlling dust when using the concrete floor polisher machine are: (1) an integrated water delivery system that continuously delivers water to the cutting surface, or (2) a commercially available vacuum dust collection system. In each case the concrete floor polisher machine must be operated and maintained in accordance with manufacturer’s instructions to minimize dust emissions.
Wet Methods
Use of wet methods effectively reduces the amount of silica dust that becomes airborne when milling or grinding silica containing materials because it controls the exposure at its source. The silica standard specifies the use of concrete floor polisher machine that are equipped with an integrated water delivery system that continuously delivers water to the cutting surface.
Employers are responsible for keeping equipment in good condition to minimize dust and for training workers on how to use the equipment. Make sure to:
- Check that hoses are securely connected and are not cracked or broken.
- Adjust nozzles so that water goes to the polishing surface or cut point. Water flow rates must be sufficient to minimize the release of visible dust.
- Ensure an adequate supply of water is available.
Clean up any slurry produced to prevent the slurry from drying and releasing silica dust into the air. Wet slurry can be cleaned up using, for example, shovels or a wet vacuum equipped with a HEPA filter.
Respiratory Protection
When properly used, wet methods and a VDCS can effectively control exposure to silica dust.Therefore, in the construction standard does not require the use of respiratory protection when operating the concrete floor polisher machine using wet methods or a VDCS.
Indoors or in enclosed Spaces
When using the concrete floor polisher machine equipped with a VCDS indoors,or in an enclosed area where dust can build up,a HEPA-filtered vacuum must be used between passes to remove loose dust.
Using wet methods or a VDCS indoors or in an enclosed area may not reliably keep exposure low, so extra ventilation may be needed to reduce visible airborne dust. Extra ventilation can be supplied by using:
- Exhaust trunks
- Portable exhaust fans
- Air ducts
- Other means of mechanical ventilation
Ensure air flow is not impeded by the movements of employees during work, or by the opening or closing of doors and windows.
Position the ventilation to move contaminated air away from the workers’ breathing zones.
Warranty
The concrete floor polisher machine are covered by a warranty for a period of 12 months from the date of purchase against defects in material or workmanship provided that:
-The product concerned has been operated and maintained in accordance with the operating instructions.
-Has not been damaged by accident, misuse or abuse.
The owner is responsible for the cost of transportation to and from the authorized repairer and the unit is at the owner’s risk while in transit to and from the repairer.
Maintenance Record
The concrete floor polisher machine has been assembled with care and will provide years of service. Preventative maintenance and routine service are essential to the long life of your the concrete floor polisher machine. After reading through this manual thoroughly, you will find that you can do some of the regular maintenance yourself. However, when in need of parts or major service, be sure to see your dealer. For your convenience we have provided this space to record relevant data about your the concrete floor polisher machine.
