A neutralizing solution of two pounds of sodium carbonate (aka baking soda) in five gallons of water or a strong ammonia solution will usually neutralize the concrete in one application. Use pH paper to determine when acid or base spills have been neutralized. the spill can be neutralized, Device used to control small fires in an a. Conversely one mole of sulfuric acid will neutralize one mole of Ca(OH) 2 (lime) as lime is also two normal: Ca(OH) 2 + H 2SO 4 CaSO 4 + 2H 20. Contact your environmental health and safety officer for guidance in packaging and labeling cleanup residues. Evaluate the following?

A soluble product that like sugar in water melts to form a syrupy like consistency and seen to be tough to clean up. For Hydrofluoric acid (HF) spills: Use Calcium carbonate or Calcium bicarbonate to tightly bind the fluoride ion. Check for compatible uses of chemicals, particularly solvents or aggressive solutions. The reaction of the caustic soda with sulfuric acid produces an aqueous form of sodium sulfate, which is safe to discard. Equipment. To determine whether a spill is simple or complex (which is often the hardest part of spill response), you need to know (1) the hazard(s) posed by the spilled chemical and (2) the spill's potential impact. Vinegar and lemon juice can be mixed and swabbed onto the battery and/or spill to neutralize the acid. Potential health effects is the most important hazard category to consider when deciding whether or not to attempt a spill cleanup. The following chemical properties are of most concern when preparing for possible chemical spills: Every laboratory should develop written spill response procedures. All used absorbent materials should be placed in heavy-duty poly bags, which are then sealed, labeled, and disposed through your facility's hazardous waste management program. The perfect solution for unknown liquid spills. Spilled mercury often accumulates in sink traps. When planning laboratory work and preparing for potential problems, determine the hazard class of all the chemicals to be used. Graduated cylinders and volumetric flasks are not designed to be heated. Experimental plans should only involve chemicals that are actually needed for the desired results. Offers little absorbency. Often it is a good idea to wear two sets of gloves: one as the primary barrier, the second as a thin inner liner in the event the primary barrier fails.
