NREMT Advanced Emergency Medical Technician (AEMT) Practice Test

When handling hazardous materials, the safest approach is to position responders so the wind carries the hazard away from you and you’re far enough away to avoid a growing plume. Being upwind keeps you out of the direction the vapor or dust is likely to travel, and staying at the same level helps ensure you’re not in a vertical path where the cloud could settle or rise to reach you. A minimum distance of 100 feet provides a conservative buffer for dispersion, sudden wind shifts, or larger releases.

So, the statement that you should be upwind and at the same level, at least 100 feet away, best describes a safe zone. Being closer, downwind, or directly adjacent would increase exposure risk and is not advisable.
