Critical Response Protocol: Bio-Containment Pressure Loss & Ventilation Failure

1. Medical Wing, Room Number & Patient Isolation Metadata

This section captures critical location and patient isolation data to establish the scope and risk level of the HVAC emergency. All fields marked mandatory must be completed before proceeding to subsequent sections.

Healthcare Facility Name

Medical Wing/Zone Identifier

Bio-Containment Room Number(s)

Bio-Safety Level (BSL) Classification

BSL-2 Enhanced

BSL-3

BSL-3 Enhanced

BSL-4

Total Number of Patients in Affected Unit(s)

Are patients infected with high-consequence infectious agents?

Yes

No

Specify pathogen(s) and strain if known:

Exact Time of Pressure/Ventilation Failure Detection

Number of Clinical Staff Present in Unit at Time of Failure

Additional Isolation Metadata or Special Considerations

2. Airflow Pressure Delta & HEPA Filtration Diagnostic Check

Document all pressure differential measurements and HEPA filtration system diagnostics. Compare current readings against established baselines to determine deviation severity.

Pressure Differential Measurements (in Pascals)

	Location/Room Pair	Required Baseline Pressure	Actual Pressure at Detection	Current Pressure (Post-Initial Response)	Deviation from Baseline	Within Acceptable Tolerance?
	A	B	C	D	E	F
1	Patient Room to Anteroom	-25	-15	-18	10
2	Anteroom to Corridor	-15	-8	-10	7
3	Bathroom to Patient Room	-10	-5	-8	5

Primary HEPA Filter Differential Pressure (Pa)

HEPA Filter Integrity Test (PAO/DEHS) Passed?

Yes

No

Describe filter integrity failure and suspected cause:

Supply Air Flow Rate (m³/h)

Exhaust Air Flow Rate (m³/h)

Were any HEPA filter housings or seals visually compromised?

Yes

No

Detail location and extent of damage:

Critical Pressure Alarm Activated?

Yes

No

Alarm response actions taken:

Additional Diagnostic Observations

3. Emergency Patient Relocation & Biological Containment Lockdown Log

Was Emergency Patient Relocation Required?

Yes

No

Justification for relocation decision:

Rationale for maintaining in-place containment:

Relocation Initiation Time (if applicable)

Relocation Completion Time (if applicable)

Destination Relocation Room Number(s)

Patient Condition During Relocation

Stable

Monitored - Minor Concern

Unstable - Required Intervention

Critical - Emergency Support Required

Were patients transported using negative pressure isolation pods?

Yes

No

Alternative transport method used and justification:

I confirm that all transport personnel utilized appropriate PPE (N95 or higher, gowns, gloves, eye protection)

Biological Containment Lockdown Initiated

Was there any breach of primary containment during the incident?

Yes

No

Detail breach circumstances, duration, and exposure risk assessment:
