Fig. 8 Petrolatum and microcrystalline tapes do not require abrasive blasting for surface preparation, so they can be applied over water or in other environmentally sensitive areas. The microcrystalline tape application shown here did not require an outerwrap. More

Fig. 4 Vacuum blasting is an example of local exhaust ventilation. When feasible, local exhaust ventilation is preferable because it controls atmospheric hazards at the source. More
