When approaching the incident scene the survey instrument should be set on what scale?

When approaching an incident scene, the survey instrument should typically be set on the appropriate scale that corresponds to the expected levels of radiation or hazardous materials present. For radiation detection, common scales include auto-ranging or a specific low range to ensure accurate readings. It's essential to assess the situation and adjust the scale as necessary to capture the most relevant data without saturating the instrument. Always prioritize safety and follow standard operating procedures for calibration and use.
