Infection Control Risk Assessment 2.0 Matrix of Precautions for Construction, Renovation and Operations

April 2022 based on most current information

Construction or renovation projects can introduce unique risks to the healthcare environment which can obstruct infection control plans and create risks for patients, visitors and healthcare workers. A multi-disciplinary team, to include facility IP’s, is critical to each phase of activity to mitigate and prevent risk factors. The ICRA is signed by the contractor or supervisor of the project. Once barrier is placed the IP inspects and then post on barrier. A copy is maintained in the IPC Office

Step One:

Using Table 1, identify the Construction Project Activity Type (A-D).

Table 1 - Construction Project Activity Type:

Type A

Inspection and non-invasive activities.

Includes but is not limited to:

• Removal of ceiling tile for visual inspection-limited to 1 tile per 50 square feet with limited exposure time.

• Limited building system maintenance (e.g., pneumatic tube station, HVAC system, fire suppression system, electrical and carpentry work to include painting without sanding) that does not create dust or debris.

• Clean plumbing activity limited in nature.

Type B

Small-scale, short duration activities that create minimal dust and debris.

Includes but is not limited to:

• Work conducted above the ceiling (e.g., prolonged inspection or repair of firewalls and barriers, installation of conduit and/or cabling, and access to mechanical and/or electrical chase spaces).

• Fan shutdown/startup.

• Installation of electrical devices or new flooring that produces minimal dust and debris.

• The removal of drywall where minimal dust and debris is created.

• Controlled sanding activities (e.g., wet or dry sanding) that produce minimal dust and debris.

Type C

Large-scale, longer duration activities that create a moderate amount of dust and debris.

Includes but is not limited to:

• Removal of preexisting floor covering, walls, casework or other building components.

• New drywall placement.

• Renovation work in a single room.

• Non-existing cable pathway or invasive electrical work above ceilings.

• The removal of drywall where a moderate amount of dust and debris is created.

• Dry sanding where a moderate amount of dust and debris is created.

• Work creating significant vibration and/or noise.

• Any activity that cannot be completed in a single work shift.

Type D

Major demolition and construction activities.

Includes but is not limited to:

• Removal or replacement of building system component(s).

• Removal/installation of drywall partitions.

• Invasive large-scale new building construction.

• Renovation work in two or more rooms.

Step Two:

Using Table 2, identify the Patient Risk Group(s) that will be affected. If more than one risk group will be affected, select the higher risk group.

Table 2 - Patient Risk Group:

Low Risk/Group 1

Non-patient care areas such as:

Medium Risk/Group 2

Patient care support areas such as:

High Risk/Group 3

Patient care areas such as:

Highest Risk/Group 4

Procedural, invasive, sterile support and highly compromised patient care areas such as:

• Public hallways and gathering areas not on clinical units.

• Office areas not on clinical units.

• Breakrooms not on clinical units.

• Bathrooms or locker rooms not on clinical units.

• Mechanical rooms not on clinical units.

• EVS closets not on clinical units.

• Medical and Dental Waiting areas.

• Clinical engineering.

• Materials management.

• Sterile processing department - dirty side.

• Kitchen, cafeteria, gift shop, coffee shop, and food kiosks.

• Patient care rooms and areas.

• Dental treatment rooms (DTR’s) and dental areas.

• All acute care units

• Emergency department.

• Employee health

• Pharmacy - general work zone.

• Medication rooms and clean utility rooms

• Imaging suites:

diagnostic imaging.

• Laboratory.

• All transplant and intensive care units.

• All oncology units.

• OR theaters and restricted areas.

• Procedural suites.

• Pharmacy compounding.

• Sterile processing department - clean side medical and dental locations.

• Transfusion services.

• Dedicated isolation wards/units.

• Imaging suites: invasive imaging.

Step Three:

Match the Patient Risk Group (Low, Medium, High, Highest) from Step Two with the planned Construction Activity Project Type (A, B, C, D) from Step One using Table 3 to find the Class of Precautions (I, II, III, IV or V) or level of infection control activities required. The activities are listed in Table 5 – Minimum Required Infection Control Precautions by Class.

Table 3 - Class of Precautions (I-IV):

Construction Project Type Patient Risk Group TYPE A TYPE B TYPE C TYPE D Group 1 I II II III Group 2 I II III IV Group 3 I III IV V Group 4 III IV V V

April 2022 based on most current information

Infection control permit and approval will be required when Class of Precautions III (Type C) and all Class of Precautions IV or V are necessary.

Environmental conditions that could affect human health, such as sewage, mold, asbestos, gray water and black water will require Class of Precautions IV for LOW and MEDIUM Risk Groups and Class of Precautions V for HIGH and HIGHEST Risk Groups.

Step Four:

Assess potential risk to areas surrounding the project. Using Table 4, identify the surrounding areas that will be affected and the type of impact that will occur. If more than one risk group will be affected, select the higher risk group using Table 2 - Patient Risk Group.

Use electric sheers instead of reciprocating saw for ductwork cutting.

Install exterior man/material lifts.

Ventilation & Pressurization Mitigation Strategies HEPA to exterior.

Install temporary ductwork.

Utilize temporary HVAC equipment.

Vacate the area.

Install temporary partitions.

Use carbon filtration to filter odors.

Table 5 - Minimum Required Infection Control Precautions by Class | Before and During Work Activity

Class of Precautions

Mitigation Activities (Performed Before and During Work Activity)

Class I 1. Perform noninvasive work activity as to not block or interrupt patient care.

2. Perform noninvasive work activities in areas that are not directly occupied with patients.

3. Perform noninvasive work activity in a manner that does not create dust.

4. Immediately replace any displaced ceiling tile before leaving the area and/or at end of noninvasive work activity.

Class II 1. Perform only limited dust work and/or activities designed for basic facilities and engineering work.

2. Perform limited dust and invasive work following standing precautions procedures approved by the organization.

3. This Class of Precautions must never be used for construction or renovation activities.

Class III 1. Provide active means to prevent airborne dust dispersion into the occupied areas.

2. Means for controlling minimal dust dispersion may include hand-held HEPA vacuum devices, polyethylene plastic containment, or isolation of work area by closing room door.

3. Remove or isolate return air diffusers to avoid dust from entering the HVAC system.

4. Remove or isolate the supply air diffusers to avoid positive pressurization of the space,

5. If work area is contained, then it must be neutrally to negatively pressurized at all times.

6. Seal all doors with tape that will not leave residue.

7. Contain all trash and debris in the work area.

8. Nonporous/smooth and cleanable containers (with a hard lid) must be used to transport trash and debris from the construction areas. These containers must be damp-wiped cleaned and free of visible dust/debris before leaving the contained work area.

9. Install a sticky (dust collection) mat at entrance of contained work area based on facility policy. Sticky mats must be changed routinely and when visibly soiled.

10. Maintain clean surroundings when area is not contained by damp mopping or HEPA vacuuming surfaces.

Plastic barriers must be effectively affixed to ground and ceiling and secure from movement or damage. Apply tape that will not leave a residue to seal gaps between barriers, ceiling or floor.

3. Seal all penetrations in containment barriers, including floors and ceiling, using approved materials (UL schedule firestop if applicable for barrier type).
