Read the first 7 Materials, Tools, & Safety in Prosthetics flashcards as text

  1. A prosthetic technician develops a skin rash after repeated contact with uncured epoxy. What is the MOST appropriate corrective action?

    Answer: Use nitrile gloves and barrier cream; consult occupational health

    Epoxy sensitization requires eliminating skin contact through proper PPE; continued exposure worsens sensitization and occupational health evaluation is warranted.

  2. Which fastener type is preferred when attaching metal components to carbon fiber sockets to prevent galvanic corrosion?

    Answer: Titanium or stainless steel fasteners with isolating washers

    Titanium or stainless steel fasteners with isolating washers prevent galvanic corrosion at the dissimilar metal interface with carbon fiber.

  3. What is the primary purpose of applying a release agent to a positive mold before lamination?

    Answer: To prevent the lamination from permanently bonding to the mold

    Release agents create a barrier between the mold surface and the laminate, allowing clean separation after curing without damaging either.

  4. When using a heat gun to spot-modify a polypropylene socket, holding the gun too close primarily risks which outcome?

    Answer: Scorching or burning the polymer

    Excessive heat concentration from a heat gun held too close scorches and degrades polypropylene, weakening the structural integrity of the socket.

  5. Which standard does the FDA reference for testing the biocompatibility of materials used in direct skin contact prosthetic components?

    Answer: ISO 10993

    ISO 10993 provides a framework for evaluating the biological safety of medical device materials, including skin-contact prosthetic components.

  6. In a lamination vacuum bag setup, what is the function of the bleeder cloth layer?

    Answer: To absorb excess resin and allow uniform vacuum pressure distribution

    Bleeder cloth absorbs surplus resin and ensures even vacuum pressure across the layup, resulting in a consistent fiber-to-resin ratio.

  7. A grinding wheel shows visible cracks before use. The correct action is to:

    Answer: Tag it out of service and replace it immediately

    A cracked grinding wheel can shatter at operating speed, posing severe injury risk; it must be immediately removed from service and replaced.
