Two-part metering overview for hazmat responders. These videos explain what common meters actually measure, why readings matter more than waiting for alarms, and how to turn instrument data into safer decisions on scene. Part 1 covers metering goals and zone establishment, plus hazard priorities like radiation, flammability, oxygen, toxics and corrosivity. Part 2 walks the language of meters — response time, diffusion versus pump sampling, sensitivity and selectivity, cross-sensitivities, calibration and bump tests, relative response and common interferences — so you can interpret readings instead of just reacting to beeps. Watch both parts to reframe how you read instruments and improve operational judgment.
