Equipment Operation & Maintenance Flashcards

What is the primary purpose of a bench grinder's tool rest in a prosthetic lab?

Answer: To support the workpiece at a consistent angle for safe grinding

The tool rest supports the workpiece at a safe, consistent angle to prevent it from being caught by the wheel.

When operating a drill press for prosthetic component fabrication, which action should be taken before changing drill bits?

Answer: Lock the chuck with a chuck key and power off the machine

The machine must be powered off and the chuck locked before bit changes to prevent accidental startup and injury.

Which maintenance task should be performed on a vacuum-forming machine's heating element at regular intervals?

Answer: Inspect for oxidation and clean with a dry cloth

Heating elements should be inspected for oxidation and cleaned with a dry cloth to maintain even heat distribution.

A band saw blade in a prosthetic lab breaks during use. What is the first corrective step?

Answer: Power off the machine and wait for all motion to stop before opening guards

Always power off and wait for complete stop before opening any guards or accessing a broken blade.

In a prosthetic fabrication lab, what is the recommended frequency for inspecting abrasive grinding wheels for cracks?

Answer: Before each use

Grinding wheels should be visually inspected and ring-tested before each use to detect cracks that could cause catastrophic failure.

What type of personal protective equipment is mandatory when operating a lathe for prosthetic socket fabrication?

Answer: Safety glasses and no loose clothing or gloves

Safety glasses are required, but gloves are prohibited on a lathe because they can catch rotating parts and pull the hand in.

When storing lamination resins and solvents in the prosthetic lab, which condition is most important to maintain?

Answer: Cool temperature away from ignition sources

Flammable resins and solvents must be stored cool and away from ignition sources to prevent fire or explosion.
