PCRA and ICRA Requiremnts.pdf

In a VA Medical Center (VAMC), electrical work is subject to stringent safety and clinical standards. You must complete two primary risk assessments before any work begins: the Pre-Construction Risk Assessment (PCRA) and the Infection Control Risk Assessment

(ICRA).

While the ICRA focuses on patient health and dust containment, the PCRA is a broader safety evaluation that covers the impact of your work on the building’s systems and life safety.

1. Pre-Construction Risk Assessment (PCRA)

The PCRA identifies how construction activities might affect the safety of patients, staff, and the facility's infrastructure. For electrical work, the key focus is often on Utility Interruptions and Life Safety.

Key PCRA Requirements for Electrical Work:

• Utility Disruptions: You must identify any planned outages. If an outage affects critical systems (like life support or fire alarms) for more than 4 hours, you must implement Interim Life Safety Measures (ILSM), which may include a 24-hour fire watch.

• Life Safety Impact: If your work involves running conduit through fire-rated walls or smoke barriers, the PCRA requires you to detail how you will maintain the integrity of those barriers (e.g., using UL-listed firestopping materials).

• Noise and Vibration: Electrical work involving core drilling or heavy hammering must be scheduled to minimize disruption to sensitive clinical areas (e.g., ICUs or Operating Rooms).

• Security: You must coordinate how you will access electrical closets and how those spaces will be secured to prevent unauthorized patient access.

2. Infection Control Risk Assessment (ICRA)

The ICRA is designed to prevent the spread of dust, mold, and airborne pathogens (like Aspergillus) that can be fatal to immunocompromised patients. ICRA requirements are determined by a matrix that crosses the Work Class with the Patient Risk Group.

ICRA Class Levels for Common Electrical Tasks:

• Class I (Low Risk): Tasks like replacing a light bulb or an outlet cover.

o Requirements: Clean up immediately; replace any moved ceiling tiles.

• Class II (Moderate Risk): Minor cabling or installing conduit above ceilings where minimal dust is created.

o Requirements: Use a "control cube" (mobile containment) or plastic sheeting to prevent dust; use a HEPA-filtered vacuum for cleanup.

• Class III (High Risk): Extensive cabling or new electrical runs that require removing multiple ceiling tiles or wall sections.

o Requirements: Negative air pressure must be maintained in the work area using a HEPA air machine. All waste must be transported in covered carts.

• Class IV (Highest Risk): Major electrical renovations or work in "Highest Risk" areas like Sterile Processing or the Operating Room.

o Requirements: Construct airtight hard barriers; install an anteroom for workers to don/doff PPE; maintain 24/7 negative air pressure with documented monitoring.

3. Mandatory Documentation

To get your permit to work, the VA typically requires the following from the electrical contractor:

1. Safety Data Sheets (SDS): For any firestopping caulks, lubricants, or solvents.

2. OSHA Certifications: Verification of OSHA 10-hour (workers) and OSHA 30-hour

(supervisors) training.

3. HEPA Certifications: Proof that any HEPA vacuums or air scrubbers have been tested and certified within the last 12 months.

4. Daily Logs: A record of ICRA compliance, including daily pressure readings if negative air is required.

ICRA Class III Checklist: Electrical Conduit Installation (Example)

1. Pre-Work Setup & Containment

• [ ] Barrier Installation: Construct a dust-tight barrier from floor to deck. If using a mobile containment cube, ensure the seal against the ceiling is airtight.

• [ ] Negative Air Machine (NAM): Deploy a HEPA-filtered air scrubber. Ensure the filter is clean and the unit is exhausted properly (ideally to the outside or into a return duct if approved).

• [ ] Pressure Monitoring: Install a manometer or "tattletale" to verify that air is pulling into the work area. A minimum of -0.02 inches of water gauge ("w.g.) is the standard healthcare requirement.

• [ ] Entry/Exit: Ensure there is a flap or door at the entry point to minimize air loss during transit.

• [ ] Walk-off Mats: Place adhesive "tacky" mats at the exit to remove dust from boots. Replace layers as soon as they lose stickiness.

2. During Electrical Operations

• [ ] Dust Suppression: Use a HEPA-integrated vacuum shroud when drilling into concrete, masonry, or drywall.

• [ ] Ceiling Tile Management: Keep removed tiles inside the containment area. Do not leave "open holes" in the ceiling outside of the barrier.

• [ ] Waste Management: All debris (wire scraps, drywall bits, conduit off-cuts) must be placed in a sturdy container and misted/covered before being moved through the hospital.

• [ ] Tool Hygiene: Ensure all power tools are wiped down and free of heavy dust before being brought into the facility.

3. Cleanup & Demobilization

• [ ] HEPA Vacuuming: Vacuum all horizontal surfaces (tops of conduits, junction boxes, and floor) within the containment area.

• [ ] Wet Mopping/Wiping: Wipe down all surfaces with a hospital-approved disinfectant/cleaner.

• [ ] Final Inspection: The VA Infection Control Officer or Safety Officer must inspect the area before barriers are removed.

• [ ] Barrier Removal: Carefully mist the plastic barriers before dismantling to prevent dried dust from becoming airborne. Remove plastic by folding the "dirty side" inward.

4. Mandatory Documentation (The "Paper Trail")

• [ ] Daily Log: Signed log confirming that negative pressure was maintained throughout the shift.

• [ ] HEPA Certification: A copy of the most recent DOP/PAO test for the HEPA unit (usually required to be within the last 12 months).

• [ ] PCRA/ILSM Check: Ensure that if any fire-rated penetrations were made for the conduit, they have been sealed with UL-listed firestop and documented on the Life Safety log.

Pro-Tip for VA Electrical Contractors

VA inspectors are particularly strict about above-ceiling "cleanliness." Even if your floor looks perfect, they will often stick their head above the ceiling tile to ensure you haven't left wire insulation or metal shavings on top of the grid or existing pipes.
