What is the purpose of the TruDefender?

• A. Identify unknown chemicals
• B. Measure air pressure
• C. Determine ignition temperature
• D. Scan for moisture

Answer: (A)

TruDefender is a handheld tool designed for rapid identification of unknown chemicals at incident scenes. It analyzes chemical signatures from vapors or materials and matches them against a built-in library to determine what substance is present. This identification supports risk assessment and guides critical actions like selecting appropriate PPE, deciding on evacuation or isolation, and choosing proper decontamination steps. It’s specialized for recognizing what the chemical is, rather than measuring other environmental parameters. It does not measure air pressure, ignition temperature, or moisture; different instruments are used for those purposes. By turning an unknown sample into a specific chemical identity, it helps responders act quickly and appropriately.
