WI DHS Weapons of Mass Destruction (2013)
WCTCFire&EMS
Overview
This training module introduces the concept of terrorism and weapons of mass destruction (WMD) for emergency responders. It defines terrorism, outlines historical and current trends, and details various types of WMD threats, including explosives, chemical agents, biological agents, and radiological materials. The presentation emphasizes the importance of understanding potential targets, recognizing terrorist tactics, and outlines crucial response protocols for first responders, including scene safety, establishing perimeters, decontamination procedures, and inter-agency coordination. The goal is to enhance awareness and preparedness for terrorist incidents, thereby increasing the safety of both the public and emergency personnel.

Chapters
- Terrorism is defined by illegal acts involving force, intended to intimidate or coerce, and committed to achieve political or social objectives.
- A threat is characterized by both the motive and the ability of an individual or group to carry out an attack.
- Terrorist acts can be perpetrated by organized groups or lone individuals, and they are distinguished from legitimate organizations by their criminal component.
- Terrorism can be classified as domestic (within the U.S.) or international (transcending borders).
Understanding the core definition and elements of terrorism helps responders recognize the unique nature of these incidents beyond typical emergencies, informing their approach and risk assessment.
The 1993 World Trade Center bombing and the 2001 attacks are cited as examples of significant terrorist events.
- Terrorists are motivated by various ideologies, targeting symbols of national pride, government installations, infrastructure, and venues of mass assembly.
- Common terrorist tactics include bombings (most frequent), shootings, and the use of improvised explosive devices (IEDs).
- Secondary devices are a tactic to target first responders and increase chaos after an initial attack.
- The internet is a significant tool for terrorists for propaganda, fundraising, and planning.
Identifying potential targets and understanding common tactics allows responders to anticipate threats and implement appropriate safety measures, such as establishing wider perimeters and being vigilant for secondary devices.
The Atlanta Olympic Park bombing in 1996, which included a secondary device intended to target responders, illustrates the dangers.
- Explosive devices are the most frequent terrorist tactic, with IEDs being common and often constructed from readily available materials.
- Pipe bombs are a prevalent type of IED, ranging from simple to sophisticated designs incorporating timers or remote detonators.
- Secondary devices are a critical concern, designed to detonate after the initial event to harm responders and increase panic.
- Response to explosive incidents requires establishing safe perimeters, notifying EOD personnel, and maintaining a safe staging area, potentially 3000 feet from the site.
Knowledge of explosive devices, especially IEDs and secondary devices, is crucial for responders to maintain scene safety, protect themselves and others, and coordinate effectively with specialized units.
The 1998 Georgia abortion clinic explosion followed by a second explosion injuring responders highlights the threat of secondary devices.
- Chemical agents, like chlorine and cyanide, can cause widespread harm and are often derived from industrial chemicals, making them accessible.
- Nerve agents, such as Sarin and VX, are highly toxic and attack the central nervous system, with symptoms appearing rapidly.
- Blister agents cause severe skin burns and respiratory damage, while pulmonary agents severely damage the lungs.
- Biological agents (bacteria, viruses, toxins) can cause diseases, with potential for contagious outbreaks that could overwhelm healthcare systems; anthrax and smallpox are examples.
Understanding the distinct properties, effects, and dissemination methods of chemical and biological agents is vital for recognizing exposure, implementing appropriate personal protective equipment (PPE), and initiating timely decontamination.
The 1995 Tokyo Subway nerve agent attack, which injured nearly a thousand people, demonstrates the devastating potential of chemical agents.
- Radiological threats involve either nuclear devices or, more likely, Radiological Dispersal Devices (RDDs or 'dirty bombs') that spread radioactive material.
- Radiation types include alpha (short-range, stopped by paper), beta (medium-range, stopped by plastic/metal), and gamma (long-range, highly penetrating).
- Exposure symptoms range from immediate nausea to long-term effects like cancer, depending on the dose and type of radiation.
- Limiting exposure involves minimizing time, maximizing distance from the source, and using shielding (e.g., lead, concrete).
Recognizing radiological threats and understanding radiation principles allows responders to implement critical safety measures like time, distance, and shielding, and to conduct proper decontamination.
The concept of a 'dirty bomb,' which uses conventional explosives to disperse radioactive material, is a primary concern for radiological terrorism.
- Responders must treat potential terrorist incidents as hazardous materials scenes, approaching from upwind and uphill, and wearing full PPE.
- Establishing secure perimeters, a safe command post (cold zone), and staging areas is critical for managing the scene and preventing further contamination.
- Decontamination is essential for exposed victims and responders to remove or neutralize agents and prevent spread.
- Mass decontamination procedures may be necessary for large numbers of casualties, utilizing specialized equipment and multi-agency coordination.
Effective incident response, including scene control, hazard assessment, and decontamination, is paramount to saving lives, protecting responders, and mitigating the long-term impact of WMD events.
The need for decontamination is highlighted by the risk of spreading radioactive material to ambulances and hospitals if not handled properly.
Key takeaways
- Terrorism is a deliberate act of violence or threat intended to intimidate for political or social gain, distinguishable by its criminal nature.
- First responders must always consider the possibility of terrorism, even in seemingly routine incidents, due to the evolving tactics and targets of adversaries.
- Understanding the specific characteristics and dangers of explosives, chemical, biological, and radiological agents is crucial for effective response.
- Scene safety for responders is paramount, requiring adherence to protocols like establishing safe perimeters, using appropriate PPE, and maintaining distance from potential hazards.
- Secondary devices are a significant threat designed to target first responders, necessitating extreme caution and strategic staging.
- Decontamination is a critical step in WMD incidents to prevent further exposure and the spread of hazardous materials.
- Effective response to WMD terrorism relies heavily on inter-agency cooperation, clear communication, and well-rehearsed joint training exercises.
