Protecting Yourself while Responding to Chemical Incidents: Safety and Health Awareness for Responders to Chemical Incidents [open pdf - 2MB]
"This training tool is an awareness-level health and safety resource for 'skilled support personnel' who will participate in a response to a chemical release (including weapons and industrial chemicals) and are not required to get chemical training under 1910.120. It can also be used as a refresher course for those with a minimum level of training. This tool will help workers understand at an awareness level: the basics of chemical weapons deployment, how to protect against chemical and other hazards associated with a chemical release and response. Trainers may use this tool to aid in the development of a awareness level chemical release course or other awareness level materials (fact-sheets, table-top activities, etc.)."
