In the left Tab there is a HAZMAT Map button. It will ask you to launch it in a new window. If this doesn’t not work try launching it directly from this link: http://hazmat.globalincidentmap.com/map.php
Pick a Hazmat response (possibly in area you live or your home town). Explain why you chose it, describe what the chemical was, (give its chemical and physical properties) its potential hazards and the response (if any). Do not just cut and paste from the article, as I do check your work. If you like you can call the hazmat team (if provided) and talk with them directly about the incident.
