TO 1-1-700 11.11.2 Control of Mechanical Damage During Abrasive Blasting. Figure 11-2. Abrasive Flap Wheels with Spindle Mount • Use extreme care to ensure that blast media does not contaminate hydraulic, fuel, oil, or coolant systems. Blockages in critical components caused by abrasive media particles can result operational failures and severe damage to equipment. • Finely divided dried particles of many materials (metallic, organic, and inorganic) can form explosive mixtures with air resulting in dust explosion hazards. Use extreme care when dry abrasive blasting magnesium and titanium alloys, and provide adequate ventilation to prevent formation of explosive dust mixtures during all abrasive blasting operations. • Abrasive blasting operations shall not subject these surfaces to severe abrasive action. • Dry abrasive blasting of titanium alloys and high strength steel will create sparking. Ensure that the abrasive blasting area is free of all flammable vapors and liquids. • Protect areas adjacent to abrasive blasting corrosion removal operations from chips, dust, and other debris which could produce dissimilar metal/ galvanic corrosion on previously corrosion free surfaces. • Use only those abrasive blasting media recommended in Table 11-1 and do not reuse this media on a different type metal to prevent dissimilar metal particles from becoming embedded in surfaces and generating rapid galvanic corrosion. • Do not use abrasive blasting to remove corrosion from soft plated surfaces (zinc, cadmium, etc.). Soft plating is easily damaged or removed by mechanical methods. 11.11.3 Abrasive Blasting Corrosion Removal. Before beginning abrasive blasting operations, ensure that all safety precautions listed in the warnings and cautions are fully observed. Failure to comply with these precautions may result in harm to personnel and equipment. 11-8
TO 1-1-700 11.11.3.1 Personal Protection. • Many materials such as copper alloys, especially beryllium-copper (see Chapter 7 of TO 1-1-691); cadmium plate; chromate conversion coatings; paints containing chromates; lead; barium; strontium; and chemicals used for corrosion removal are toxic. Use approved respirators, eye protection, and skin protection. Take proper safety precautions to avoid inhalation or ingestion of chemical fumes or liquids and dust from corrosion products during abrasive blasting corrosion removal. Wash hands thoroughly before eating or smoking. • All powered abrasive blasting corrosion removal procedures create airborne particles. Respirators and eye protection and adequate ventilation are required. • It is essential that all blasting media and other residue be completely removed after abrasive blasting operations. The blasting media can be very slippery and can cause dangerous falls. • Operators shall be adequately protected with complete face and head covering equipment, and provided with pure breathing air per requirements of AFOSH Standard 91-501 for all abrasive blasting operations. 11.11.3.2 Abrasive Blasting Procedures. Accomplish abrasive blasting operations using the procedures outlined in Chapter 5 of TO 1-1-691. NOTE • Refer to the individual system specific equipment maintenance manuals for limits on metal removal. Do not exceed these limits without engineering approval from the equipment SPM. • Abrasive blasting shall be used on stainless steel (CRES) and nickel alloy parts only to remove severe/heavy corrosion and prior to acid pickling and/or passivation. 11.12 NON-POWERED AND POWERED TOOL COR- ROSION REMOVAL. The following WARNINGS and CAUTIONS shall be observed during corrosion removal operations: 11.12.1 Personal Protection. • Many materials such as copper alloys, especially beryllium-copper (see Chapter 7 of TO 1-1-691); cadmium plate; chromate conversion coatings; paints containing chromates; lead; barium; strontium; and chemicals used for corrosion removal are toxic. Use approved respirators, eye protection, and skin protection. Take proper safety precautions to avoid inhalation or ingestion of chemical fumes or liquids and dust from corrosion products during corrosion removal. Wash hands thoroughly before eating or smoking. • All powered mechanical corrosion removal procedures create airborne particles. Respirators and eye protection and adequate ventilation are required. • Wear leather gloves when using metallic wools to prevent hand injuries. • Do not use abrasive flap brushes, wheels, discs or wire brushes above their authorized RPM rating. These tools can fly apart, causing serious injury. • Exercise caution when using sharp or pointed tools to prevent injury. • Abrasive blasting will not remove intergranular and/or exfoliation corrosion from aluminum alloys. 11-9
