The threat of Chemical, Biological, Radiological, Nuclear, and high-yield Explosive (CBRNe) agents is a constant concern in military operations. Ensuring the effectiveness of CBRN Personal Protective Equipment (PPE), particularly respiratory protection, is critical to mission success and the safety of warfighters. The OmniCount™ Wearable Respiratory Protection Assessment System (WRPAS) from TSI® provides a powerful, real-time solution for verifying/validating respirator fit and performance in battlefield environments.
This advanced system moves beyond traditional quantitative CBRN respirator fit testing by delivering continuous protection factor data during demanding physical activities. It offers an unprecedented level of insight into how a CBRN respirator performs under the realistic stresses of battlefield operations, helping ensure that warfighters are truly protected when it matters most.
Innovative Features for Unmatched Performance
The OmniCount™ WRPAS is engineered specifically for use in challenging conditions where other systems fail. Its design incorporates several key features that make it indispensable for battlefield operations.
Continuous, Real-Time Measurement
Unlike quantitative respirator fit tests that provide a single data point in a controlled setting, the OmniCount™ WRPAS continuously measures the particle concentration inside and outside the respirator. This generates continuous real-time protection factor, allowing military commanders and safety officers to see exactly how a CBRN respirator performs moment by moment. This capability is crucial for identifying intermittent leaks or failures that may occur during specific movements or actions.
Motion-Capable Design
Military warfighters rarely stand still. The OmniCount™ WRPAS is designed for portability and 3-dimensional motion capability, enabling accurate measurements while warfighters are actively engaged in mission-relevant battlefield tasks. Its lightweight and wearable configuration ensures that it does not hinder movement or add significant burden to the user's loadout. This allows for performance assessment during dynamic activities that simulate real-world battlefield operational stress.
Ultrafine Particle Detection
The system excels at measuring ultrafine particles (UFP), which are present in high concentrations in ambient air and are a reliable indicator of CBRN respirator leakage. By focusing on these tiny particles, the OmniCount™ WRPAS can detect even minor changes in fit with high sensitivity, providing a more accurate assessment of the CBRN respirator's face seal and filtration capabilities.
Validated in Military-Relevant Scenarios
The effectiveness of the OmniCount™ WRPAS was rigorously tested in a field study conducted at a military research wind tunnel facility. This study was designed to evaluate the system's performance under conditions that closely mimic operational environments, demonstrating its versatility for a wide range of military applications, including:
- Battlefield Protection Factor Studies (BPFS): Assess respiratory protection in the presence of battlefield contaminants, providing actionable data for mission-critical scenarios.
- Simulated Workplace Protection Factor Studies (SWPFS): Evaluate equipment effectiveness during simulated tasks, allowing for controlled analysis of protection levels in conditions that replicate real deployments.
- Live-Agent Testing: Measure protection factors against actual and surrogate hazardous agents, supporting comprehensive validation under true CBRN threat conditions.
- Fit Assurance Measurements in Real-World Conditions: Deliver continuous fit-to-face assessment for personnel operating in complex environments, helping ensure optimal equipment performance during field operations.
The OmniCount™ WRPAS also enables expedited fit checks in the field, allowing quick verification of adequate protection just prior to entering a threat environment. This real-time assurance can be critical for safety and operational readiness.
Testing During Dynamic Activities
During the study, test subjects wore the OmniCount™ WRPAS with their CBRN respirators while performing a series of military-relevant activities inside the wind tunnel. These tasks included activities such as:
- Running in place
- Crawling and climbing over obstacles
- Shoveling
- Simulating weapon handling
The system successfully provided continuous, real-time protection factor measurements throughout these strenuous activities. The data collected revealed how different movements and exertion levels impacted the integrity of the respirator seal, offering valuable insights into training and equipment selection.
Proven Reliability in High-Threat Scenarios
The wind tunnel environment simulated exposure to CBRN threats, confirming the ability of the OmniCount™ WRPAS to function reliably in high-risk settings. The study demonstrated that the technology is robust enough for field deployment, providing military commanders with a dependable tool for verifying PPE effectiveness before and during missions. The motion-tolerant design proved essential, as the system maintained accuracy despite the constant jarring and movement associated with the physical tasks.
The Significance of Advanced Respiratory Protection Assessment
The ability to accurately assess respiratory protection in real-time under operational stress represents a significant advancement in military readiness. The OmniCount™ WRPAS helps provide a clear, data-driven picture of equipment performance in the field.
By integrating this technology, military units can:
- Enhance Warfighter Safety: Identify and correct respirator fit issues before personnel enter contaminated environments, reducing the risk of exposure to hazardous agents.
- Improve Training Effectiveness: Use real-time feedback to train warfighters on how to maintain a proper respirator seal during physically demanding tasks.
- Optimize Equipment Selection: Evaluate and compare the performance of different respirator models under realistic conditions to select the most effective CBRN respirators for specific missions.
- Increase Mission Confidence: Provide warfighters with the assurance that their protective equipment is functioning correctly, allowing them to focus on their objectives with greater confidence.
A New Standard in Military Safety
The OmniCount™ WRPAS sets a new standard for evaluating respiratory protection in military applications. Its ability to provide continuous, real-time protection factor data during dynamic activities makes it a uniquely powerful tool for enhancing the safety and effectiveness of military personnel. By moving assessments from the controlled test chamber to the operational battlefield environment, this innovative system helps ensure that our armed forces are prepared and protected against the most challenging CBRN threats.
