220-1102 Operational Procedures Practice Question

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  Place them in the regular office trash for collection.

  Why it's wrong here

  Regular office trash is unacceptable because lithium-ion and other rechargeable batteries contain heavy metals, caustic electrolytes, and can short-circuit under pressure. In a landfill, casings corrode and leach toxic substances like cobalt and lithium into soil and groundwater, and if damaged during compaction they can start fires in garbage trucks or processing facilities. Most municipalities classify them as household hazardous waste requiring special collection.

• ✓

  Recycle them through an approved electronics recycling vendor or battery drop-off program.

  Why this is correct

  Approved e-waste recycling vendors and battery drop-off programs are the correct route because they safely manage hazardous components in accordance with regulations such as the Resource Conservation and Recovery Act (RCRA). These programs sort chemistries, stabilize or neutralize reactive materials, and recover valuable metals (lithium, cobalt, nickel) for reuse, preventing both environmental contamination and the risk of landfill fires. Many states mandate take-back programs, so using an authorized recycler also ensures legal compliance.

• ✗

  Incinerate them at a licensed waste-to-energy facility.

  Why it's wrong here

  Incinerating batteries in a waste-to-energy facility is dangerous because high temperatures cause lithium-ion cells to undergo thermal runaway, potentially ejecting flaming debris or exploding. Combustion of battery plastics and electrolytes can release toxic byproducts, including hydrogen fluoride gas from lithium salts, which poses severe health risks to workers and the community. Waste-to-energy plants are not designed to handle the concentrated reactive load of batteries, so even a licensed facility would need elaborate pre-sorting and preprocessing to avoid creating a hazmat incident.

• ✗

  Donate them to a local school for use in demonstrations.

  Why it's wrong here

  Donating non-functional batteries to a school for demonstrations is unsafe, as the batteries may still contain stored energy or active chemicals that can leak, overheat, or emit fumes if punctured during student handling. Schools lack the specialized PPE, ventilation, and containment equipment required to manage hazardous waste, and accepting them for 'educational use' is effectively illegal disposal of unregulated hazardous material. Working batteries for demonstration should always be new, sealed, and purchased from a normal supplier, not end-of-life units.
