Infection Control Risk Assessment (ICRA) during Construction
This matrix is to be used to set guidelines on the appropriate infection prevention and control procedures
Control representative may add or omit requirements specific to a project. Recommended barriers are to be
installed before construction begins.
Step 1: Identify the Type of Construction Activity Planned:
Includes but is not limited to removal of ceiling tiles for visual inspection (limited to 1 tile per
that do not generate dust or require cutting of walls.
Small scale, short duration activities that create minimal dust.
Includes but is not limited to installation of telephone and computer cables, access to chase
spaces, cutting of walls or ceiling where dust migration can be easily controlled at the source.
any fixed building components or assemblies.
Includes but is not limited to sanding walls, for painting or wall coverings, removing floor
