Summary
CRCST exam snapshot (verified against HSPA on 2026-09-04): 150 computer-based multiple-choice questions in 3 hours; the current handbook describes 125 scored operational questions plus 25 unscored pretest questions. Blueprint weights are Departmental Considerations 15%, Cleaning/Decontamination/Disinfection 21%, Preparation/Packaging 21%, Sterilization Process 21%, Sterile Storage/Transport/Inventory 9%, Patient Care Equipment/Distribution 5%, and Professional Development/Human Relations 8%. Departmental Considerations is 15% of the CRCST blueprint. Know the environment, workflow, worker-safety, documentation and quality systems that keep SPD controlled. These questions reward standards/IFU-based decisions, immediate correction of deviations and traceable documentation.
Key Points
Temperature, humidity and airflow requirements by work area: Decontamination is separated from clean work and is maintained so contaminated air does not migrate into clean areas.
Common Mistakes
Memorizing one universal temperature/humidity range for every SPD area.
Exam Tips
Tie every environmental question to the function of the room.

Summary
Cleaning, Decontamination and Disinfection is 21% of the CRCST blueprint. This is one of the three heaviest domains. Think worker protection, containment, thorough cleaning, device IFU, validated equipment testing, Spaulding classification and documented disinfection control.
Key Points
OSHA bloodborne pathogen precautions: Use engineering and work-practice controls first, then appropriate PPE for remaining exposure.
Common Mistakes
Continuing because detergent is present.
Exam Tips
If PPE fails, stop, remove it safely, perform hand hygiene as required and replace it.

Key Points
Prep-and-pack work-area safety: Maintain a clean/disinfected work surface and appropriate environmental conditions.
Common Mistakes
Starting assembly on a contaminated work surface.

Key Points
High- and low-temperature sterilizer safety: Use steam for heat/moisture-compatible critical items when validated; choose low-temperature methods only when device/process compatibility requires them.
Common Mistakes
Using low temperature for convenience.
Exam Tips
Validate device + load + packaging + cycle as a system.
