<strong>Chemical</strong> <strong>Agents</strong> <strong>of</strong> <strong>Opportunity</strong> <strong>for</strong> <strong>Terrorism</strong>:<br />

<strong>TICs</strong> & <strong>TIMs</strong><br />

Key Learning Points<br />

• Legislation to regulate <strong>TICs</strong>/<strong>TIMs</strong> was generated by concerns<br />

regarding toxic gases<br />

• Releases <strong>of</strong> large volumes <strong>of</strong> compressed gas is the most<br />

likely TIC/TIM scenario<br />

• Toxicity <strong>of</strong> a gas is determined by<br />

– Dose<br />

– Inherent toxicity<br />

– Volatility<br />

– Water solubility<br />

– Warning properties<br />

– pH<br />

Module One – Toxic Industrial Gases as Terrorist Threats<br />

3<br />

Recognize that much <strong>of</strong> the chemical legislation in this country and elsewhere grew out<br />

<strong>of</strong> concern following large-scale exposures. We will present several major chemical<br />

releases in this module.<br />

By far, releases <strong>of</strong> these agents <strong>for</strong>m the most likely TIC/TIM scenario. These are the<br />

physical characteristics <strong>of</strong> an irritant gas that predict its specific toxicity – in particular,<br />

water solubility.<br />

Toxicity <strong>of</strong> a gas is determined:<br />

Dose<br />

Inherent toxicity<br />

Volatility<br />

Water solubility<br />

Warning properties<br />

pH<br />
