How do I determine the ICRA class for a hospital construction project?

Classify the construction activity (Type A through D), classify the patient risk group (Low, Medium, High, Highest), then match them in the ASHE ICRA 2.0 matrix to find the precaution class (I through V). The ICRA Class Finder tool above walks through this in three questions.

When is an infection control permit required for healthcare construction?

An infection control permit is required for Class III work involving Type C activities, and for all Class IV and Class V work — before construction begins.

What if my hospital project involves mold, sewage, or asbestos?

Environmental hazards (sewage, mold, asbestos, gray/black water) raise the minimum precaution class: Class IV for low and medium patient risk groups, Class V for high and highest risk groups, regardless of the matrix result.

ICRA Class Finder — What Precaution Class Does Your Hospital Project Need?

An Infection Control Risk Assessment (ICRA) class determines the containment precautions your hospital construction project must follow. Answer three questions — based on the ASHE ICRA 2.0 matrix — and get your class plus the required precautions instantly.

Step 1 — What kind of construction activity is it?

Step 2 — What patient risk group is the area?

Step 3 — Any environmental hazards?

Does the work involve sewage, mold, asbestos, or gray/black water? These conditions raise the minimum class regardless of the matrix result.

Important: This tool supports — it does not replace — professional judgment. Always confirm your ICRA class and precautions with your facility’s infection prevention, safety, and epidemiology teams, and against the current ASHE ICRA 2.0 standard.
