Emergency Management in the Laboratory

Emergency Management in the Laboratory

• Emergency Management Plan Components: The plan should address four phases: Mitigation, Preparedness, Response, and Recovery.
• Mitigation: Measures to reduce the negative effects of emergencies.
• Preparedness: Creating procedures, identifying resources, and training on procedures for emergencies.
• Response: Actions taken during the emergency.
• Recovery: Assessing damage, evaluating the response, and replenishing supplies to return to normal operation.
• Emergency Drill and Evaluation: Regular drills are essential to test preparedness for internal and external disasters.
• Hazard Vulnerability Analysis: Identifying potential emergencies that could impact the laboratory (e.g., utility failures, community emergencies).

Categories of Incidents

• Overt Incidents: Sudden, catastrophic events with obvious property damage and injuries; examples include explosions, bomb detonations.
• Covert Incidents: Gradual spread of an infectious agent, presenting challenges in early detection, epidemiology, and agent recognition; requires specialized laboratorian skills.

Role of Public Health During a Disaster

• Public health officials play a critical role in limiting future casualties during disasters.
• They may gather samples and microbial isolates for further testing, aiding in the investigation of disease spread.
• Their assistance is essential for protecting public health.

Elements of a Laboratory Disaster Plan

• Triage Testing: Implementing systems to prioritize testing for the most urgent samples.
• Maintaining Resources: Ensuring access to essential supplies and equipment.
• Supply Links: Maintaining connections with manufacturers and backup suppliers to ensure sufficient supplies.
• Surge Personnel: Increasing personnel to meet the demands of an emergency.
• Communication System: Maintaining a functional system for communication during an emergency.
• Reference Laboratories: Keeping communication lines open with reference labs.
• Security: Ensuring the safety and security of the laboratory facilities.

Laboratory Tests

• Essential Tests: Blood-gases, co-oximetry, electrolytes, hepatic and basic metabolic profiles, hemograms, coagulation studies.
• Additional Tests: Pseudocholinesterase (if available), microbiology, serology, and toxicology tests.
• Acute vs. Long-Term Care: Different tests may be prioritized based on the type of crisis.

Laboratory Instrumentation

• Mobility: Laboratory equipment may need to be moved to a central location for optimal emergency care.
• Examples: Blood-gas analysis, co-oximetry, electrolytes, possibly hemoglobin, and hematocrit assessment.

Laboratory Supplies

• Supply Chain: For situations exceeding 24 hours, laboratories should work with community response plans and vendors to maintain delivery and resupply.
• Collaboration: Working with community responders to identify and access additional supply sources.
• Emergency Needs: Communication with vendors is advised for the rapid assessment of usage needs during a disaster.

Specimen Transport

• Backup Plans: Essential plans must exist for specimen transport, should the current system (e.g., pneumatic tube) be compromised by an emergency.
• Personnel Identification: Necessary personnel to handle specimen transport must be identified, including laboratory staff, back-up personnel, and volunteers.
• Reference Labs: Plans to handle transport to and from reference labs should be in place.

Control of Biological, Chemical and Radiological Materials

• Outside Guidance: For unknown biological, chemical, and radiological materials, utilizing outside expert guidance during disasters.
• Material Identification: Laboratories should have lists of available labs for material identification.
• Radiation Exposure: Radiation counters, badges, and meters should be deployed for radiation exposure assessment, and appropriate personal protective equipment should be used.
• Access Control: Minimizing access points to the lab and utilizing security reviews to restrict access during emergencies.

Failure of Utilities

• Emergency Power: Laboratories need to assume major power loss and rely on emergency power.
• Instrumentation Power: Essential lab equipment must be plugged into emergency power outlets or UPS devices.

Self-Check Questions

• Safety: Ensure that electrical failures won't expose personnel to unsafe conditions or compromise the integrity of exhaust systems.
• Instruments: Verify that instruments and hoods function properly, and that cleaning procedures are available in case of shutdowns/stoppages.
• Water Source: Determine if the primary water source for instrumentation is electrical dependent and identify backup water sources (e.g., bottled/boxed water).
• Facilities: Determine if facility-level supporting services such as bathrooms and refrigerators will have backup power.
• Lighting Review lighting availability both in critical and non-critical areas.
• Emergency Power: Ensure that emergency power sources like plugs and strips are operational in all critical locations.
