General concept about Sand Blasting andPainting .

3 2 6 Sandblasting is a special physicalprocess that uses a stream of sandpropelled by water or compressed airand applied on a surface. Texassandblasting creates a powerfulabrasive force that can act on anysurface worked on using this air-propelled material. There arealternative sandblast materials that canbe used depending on the requirementof the work. These include ironglobules, emery and powdered quartz.

Sandblasting is commonly used forcleaning the cast irons in foundryshops. It is also the preparatoryprocess done on different kinds ofsurfaces before enameling, paintingand during the process of galvanizing.It is also a popular cleaning solution forsurfaces with hard to remove grimeand other debris that accumulate in theconcrete surfaces of buildings.

3 3 9 It should be noted that sandblastingand painting jobs can be hazardous asworkers are exposed to toxic elementsduring the process. There are a widerange of harmful particles which mayinclude zinc or lead which are commoncomponents in coatings. When thesandblast operations are being done ,steps should be undertaken to protectthe operation group from the harmfuleffects of the abrasive materials beingused. Protective gears like goggles andappropriate clothing are extremelyimportant if the persons are going todo sandblasting / painting work. Thepotential harm and injury that can bebrought on the person doing thesandblasting operations makes itextremely important that safetyregulations are observed before andduring any sandblasting operation.

In any typical sandblasting / paintingoperation, the standard air breathingequipment must be used. This isnecessary as the operators need tohave a steady supply of clean air in aworkplace where there is a heavyvolume of toxic and harmfulcontaminants. Before any sandblastoperation, it is imperative that theconcerned person must inspect the airbreathing apparatus to make sure thatit delivers a steady flow of clean air.The operators are strongly advised toremove the air breathing equipmentafter operation only when they at asafe distance from the work area asharmful particulates remain suspendedin the air even after the sandblastoperations.

The crew must also wear standardissue gloves and coveralls while within

3 3 9 Before undertaking any sandblastjobs, it is important that the chosenworkplace will not pose any danger andharm to the workers and the generalpublic. On top of the proper selectionof the appropriate workplace, it is alsoessential that safety procedures areobserved with regard to theappropriate sandblast / paintingmachine / devices to be used. For thedetails of the safety measures appliedto the machine, it is important that theoperator's instruction and safetymanual to be demonstrated to theoperator before any operation isstarted.
