The container should be stored away from incompatible materials such as metals, organic materials, strong bases, strong acids, oxidizing agents, amines, metal salts, silicon compounds, water, or steam. If Kim wipes, bench paper, or any other items contaminated with HF are used in the process, these also are considered Hazardous Waste.

Equipment Decontamination Decontaminate face shield, googles for re-use by rinsing with a large amount of water then rinsed with a 10% sodium carbonate solution followed by rinsing with water again. Surface decontamination Pour solid sodium bicarbonate (soda ash) or solid calcium oxide (lime), starting around the edges working inwards on the spill. Let sit for 30 minutes. Sweep solid material into a plastic dust pan. Place all contaminated items for disposal in the clear poly bag.
