Infection Control Risk Assessment Guidelines – VA San Diego Healthcare System

Identify the Type of Construction Project Activity (Types A-D) A Non-invasive activities, including, but not limited to:

a. Removal of ceiling tiles where no dust or asbestos is expected

b. Painting, but not sanding

c. Wall covering, electrical trim work, minor plumbing, and activities which do not generate dust or require cutting of walls or access to ceilings other than for visual inspection B Small scale, short duration activities which create minimal dust, including but not limited to:

a. Installation of electrical, plumbing, HVAC, telephone and computer cabling

b. Access to chase spaces where asbestos is not present

c. Cutting of walls or ceiling where dust migration can be controlled.

C Work that generates a moderate to high level of dust or requires demolition or removal of any fixed building components or assemblies, including but not limited to:

a. Sanding of surfaces for painting or wall covering

b. Removal of floor coverings, ceiling tiles, and casework

c. New wall construction

d. Minor duct work or electrical work above ceilings

e. Major cabling activities

f. Any type A, B or C activity that cannot be completed within a single work shift.

D Major demolition and construction projects, including but not limited to:

a. Activities requiring heavy demolition or removal of a complete utility or cabling system

b. New construction and renovation.

c. Friable asbestos and mold abatement projects.

Identify the Patient Risk Group that will be affected. If more than one risk group will be affected, select the higher group. For all construction classes, patients must be removed from the room while work is performed.

Low Medium High Highest Risk

All outpatient clinics, offices areas, administrative and industrial spaces.

All non-critical inpatient areas.

cardiology, echocardiography, endoscopy, nuclear medicine, rehabilitation medicine, radiology, MRI, respiratory therapy, dry research labs.

DOU, emergency room, clinical laboratory, wet lab research, ambulatory surgery, pharmacy, surgical and medical inpatient beds, procedure center.
