b. To the extent possible, solid reagent should be added to the solid waste container and broken glass should be added to the glass waste. Hazardous materials should never be added to the glass waste, and broken glass should only be allowed in the solid waste with the TA's approval.
Explanation:
All reagents, waste, equipment, and packaging used in a laboratory should be disposed of safely and appropriately to avoid environmental contamination and to avoid an accident if improperly disposed of. In a laboratory each type of reagent, waste, packaging, and equipment must be properly disposed of and specific to each. Therefore, we can conclude that if a solid reagent beaker falls off a laboratory bench and cracks, the correct thing to do is to take the solid reagent as much as possible and add it to the solid waste container and broken glass to glass waste. Hazardous materials should never be added to glass waste, and broken glass should only be allowed on solid waste with AT approval.
