In a prosthetics lab, which waste stream requires disposal as regulated medical waste (biohazardous waste)?
Answer: Soiled casting materials with blood or body fluids
Casting materials contaminated with blood or body fluids meet the definition of regulated medical waste and must be disposed of per OSHA and state biohazard waste regulations.
What is the purpose of a biological indicator (BI) in autoclave quality assurance?
Answer: To verify that sterilization conditions sufficient to kill resistant spores were achieved
Biological indicators contain highly resistant spores (e.g., Geobacillus stearothermophilus) and confirm that sterilization conditions were sufficient to kill the most resistant organisms.
A technician uses spray adhesive in a poorly ventilated area and begins to feel dizzy. This is MOST likely due to:
Answer: Solvent vapor inhalation causing central nervous system effects
Solvent vapors in spray adhesives can cause CNS effects including dizziness, headache, and disorientation when inhaled in inadequately ventilated spaces.
Which action violates safe chemical handling practices in a prosthetics fabrication lab?
Answer: Storing incompatible chemicals on the same shelf without segregation
Storing incompatible chemicals together (e.g., oxidizers with flammables) creates serious fire and explosion hazards and violates safe storage practices.
During a fire drill, a prosthetics technician in the lab should FIRST:
Answer: Turn off all tools and power, then evacuate via the nearest safe exit
Technicians should shut down powered equipment to prevent fire spread, then immediately evacuate using the nearest safe exit according to the facility's emergency action plan.
What is the correct technique for removing contaminated gloves to avoid hand contamination?
Answer: Grasp the outside of one glove cuff and peel it off, then slide fingers under the second glove's cuff to remove it
The standard doffing technique peels the first glove inside-out from the cuff, then uses the bare finger under the second cuff to keep clean skin from touching the contaminated outer surface.
Which OSHA standard specifically addresses the right of prosthetics lab employees to access Safety Data Sheets for chemicals in their workplace?
Answer: 29 CFR 1910.1200 (Hazard Communication)
OSHA's Hazard Communication Standard (29 CFR 1910.1200) grants employees the right to access Safety Data Sheets for all hazardous chemicals used in their workplace.
