Dental Waste Management Flashcards

What is the primary environmental concern with improper disposal of dental amalgam into wastewater systems?

Answer: Mercury bioaccumulation in aquatic food chains

Mercury from amalgam is converted to methylmercury by aquatic microorganisms, which bioaccumulates up the food chain, posing risks through fish consumption.

Which federal agency primarily regulates transport and disposal of regulated medical waste from dental offices?

Answer: DOT and state environmental agencies

DOT regulates transportation under 49 CFR, while state environmental agencies regulate treatment and disposal under EPA frameworks.

What is the recommended procedure for disposing of unused or expired dental pharmaceuticals?

Answer: Use a pharmaceutical waste reverse distribution program or DEA-authorized collection

Controlled substances require DEA-authorized disposal methods. Non-controlled pharmaceuticals should be collected by licensed pharmaceutical waste disposal companies.

Where must biohazard warning labels be placed according to OSHA?

Answer: On all containers of regulated waste, refrigerators storing blood, and contaminated equipment

OSHA requires biohazard labels on all regulated waste containers, refrigerators containing blood/OPIM, contaminated reusable sharps containers, and contaminated equipment being serviced.

What is the proper protocol for blood-saturated single-use items that would drip if squeezed?

Answer: Place in red biohazard bags for regulated medical waste disposal

Items that would release liquid blood if compressed meet OSHA's regulated waste definition and must go in labeled red biohazard bags via licensed medical waste hauler.

What waste management documentation must dental offices maintain for compliance?

Answer: Waste tracking manifests, hauler permits, and treatment facility documentation

A cradle-to-grave tracking system requires waste manifests, hauler permits, treatment facility certificates, staff training records, and a waste management plan.
