Hazardous Materials and Special Situations Practice Test
•2 QuestionsIn a busy subway station, a maintenance worker reports a backpack leaking a fine white powder near a bench. Several commuters are nearby, and one says, “My eyes are burning.” Station air currents push dust along the platform. You suspect a possible biological threat (e.g., anthrax powder) but cannot confirm. You keep your crew outside the station entrance and follow steps: - Stop at a safe distance; prevent others from entering - Establish zones: hot (platform area), warm (gross decon corridor), cold (staging/triage) - Instruct exposed people to move to warm zone, avoid brushing off powder, and wait for decon - Don PPE: gloves, eye protection, and an N95 or higher respirator if available; do not touch the package - Request HazMat, fire, and law enforcement; provide location, number exposed, and direction of airflow; use clear radio language. How should the EMTs establish safety perimeters in this situation?
