What is consideration for safety sand blasting?

Air supply: Air-supplied respirators must be used (1) when working inside of blast cleaning rooms, (2) when using portable units in areas without enclosure, and (3) under any circumstances where the operator is not physically separated from the abrasive material by an exhausted enclosure. If airline respirators and compressors are used, make sure the intake hose is placed in an area that provides clean air. An attendant should be in the area at all times, monitoring breathing air and assuring the blaster's safety.
Additional personal protective equipment: Blasting operations create high noise levels, so hearing protection is a must--for both the operator and nearby workers! Operators should also use heavy canvas or leather gloves, aprons, or leggings when appropriate, as well as safety shoes.
Manual cabinet blast cleaners should never be exhausted into an area where workers can breathe dusts. These fully enclosed cabinets are designed to filter out dust and re-use blasting medium.
Handling and storing abrasives: Dust is nearly always created at any point where abrasives are transferred, whether by hand or shovel. Therefore, all points of transfer must be properly exhausted and workers who handle abrasives manually should wear particulate filter respirators.

1. Whether the fixing bolts on all the blasting machine and the blasting machine motor are loose, and it is found that the loosening is immediately tightened. 2. The wear of the wear-resistant parts and the shot blasting inside the shot blasting machine, and replace the worn parts in time. 3. Check the blades and replace them when they are half worn. 4. Check if the position of the directional sleeve pointer is correct.   5. Whether the shot blasting machine inspection door is closed. 6. Whether there is air leakage in the dust removal pipe, whether the filter bag in the dust collector is dusty or damaged. 7. There are no accumulations and other debris on the spiral shell and filter screen of the separator and remove it in time. 8. Check that the flow screen of the separator is uniform and forms a full curtain. 9. Is the electronically controlled pill gate closed? 10. Check whether the status of each limit switch and proximity switch is norma...

What is sand blasting machine ? Sand blasting   is the technique of mechanical surface cleaning which uses compressed air as its power shots the high speed abrasive sand stream to the surface of work piece. Due to the impacting and cutting effect of the abrasive sand, the work piece surface is completely cleaned. At the same time, the surface quality and mechanical performance is greatly improved. It is widely used in a variety of different industries with many diverse purposes. Sand blasting is also used in refurnishing sports part of car, motorcycle, electro mechanical device, etc. It helps in removing surface marks of metal/non-metal items, dumb face and fog treatment processing to enhance the product grade. Sand blasting   is also known as abrasive blasting. It is a process where fine granular sand is applied high pressure against a rough surface keeping in mind the end goal to smooth that surface out. In this process, the abrasive material is pushed,...

Blasting is the techniques of removing dust, coating, polishing of different surfaces. There are many types of blasting process available according to the requirement like shot peening blasting. It puts small dents on the surface to give a finish where required and helps in wear resistance of the surface. The different types of blasting: Soda blasting Shot Grit Blasting Steel sandblasting Glass Bead blasting Bristle blasting Water blasting Air Blasting Sand abrasive blasting There is most common way of blasting and we called it sand blasting. It uses small grains of garnet for removing coating or polishing a surface. It is composed with the stream of compressed air that helps in acceleration of the particles while water blasting uses high pressure water guns to clean surfaces. They are available in both big and small sizes so they used in home as well as in industry also. Mayflay High Pressure Manual Abrasive Blast Cabinet Sandblasting Machine: ...
