Explanation
Standard hazmat awareness — NFPA 472 / OSHA 1910.120 First Responder Awareness Level — directs untrained personnel to evacuate, isolate, and notify. Move UPWIND and UPHILL to escape vapor/liquid flow; evacuate occupants from the affected area; deny entry; call 911 specifying possible hazmat; and provide identifying information observed from safe distance (placards, NFPA 704 diamond, container shape, color, odor). Close approach (a), spreading (b), or contact (d) put the officer at risk and may worsen contamination. Officers do NOT mitigate the release — trained hazmat teams do.
