Allows sufficient protection in hot zone of nerve agent attack for 30min Self-taped turnout gear provides sufficient protection from unknown nerve agent for 3 min--2 min if blister agent.
49
General decon procedure for WMD
Flush/shower for 2-3 minutes | Contain runoff if possible
50
Purpose of decon in WMD attack
Limit further exposure and secondary contamination | Speed is more important than method
