Biothreat and Chemical threat detectors
Protecting a building or infrastructure against biological or chemical attack involves preventing the entry of toxic substances through ventilation systems or monitoring of key location(s).
Critical infrastructure represents an attractive target for those intending to harm, due to the significance of the location or the presence of a large amount of people in a location at one time.
In the case of a ventilation system, monitoring is important so that actions can be taken as to not allow the agent to disperse throughout the facility through the ventilation system. This includes stopping the ventilation system and closing the air flow or diverting the air flow towards a filtration system capable of protecting against the threat. In the case of monitoring of key locations, the approach is to place a detector in key entry point(s) or strategic location(s) throughout. The locations are chosen to capture information as quickly as possible and to provide information in order to identify or eliminate the source and to provide quick evacuation or moving of people and equipment from the threat areas.
In both cases, it is essential to be able to sense, categorize and trigger an alarm as soon as a harmful threat is identified. In these cases, it is important to understand the sample rate, accuracy, and sensitivity levels of the detector being utilized. Sample rate is the measure of how many samples a detector can take in during a unit of time as well as how much time it takes a detector to provide information to the user after a sample is taken. Accuracy refers to proper identification of the material. It is important to understand if the detector is providing false negative or false positive information. Sensitivity level refers to the level at which the detector can start to detect or be triggered. It is important to understand the sample rate, accuracy and sensitivity level in your selection of detector technology and type. This information is also important when selecting the locations for detection equipment. It is important to match the need with the proper detector system.
AP4C technology is well suited for continual, accurate and precise monitoring of key infrastructure. Proengin AP4C-F (chemical) and AP4C-FB (chemical and biological) detectors are designed for applications where 24/7 persistent monitoring is desired. These systems only require one liter of water per month and power. Additionally, Proengin has radiological systems that can be added to our detector systems in order to provide a fully integrated package capable of monitoring radiological, nuclear, chemical, and biological threats in a single system. Proengin sensors can also be networked remotely to protect large sites or infrastructure where multiple nodes or critical points exist. Our detectors utilize an open architecture approach and can also be easily integrated into existing building management or security systems or used as stand-alone systems using our Visualization and Control Modules.
