June CEUs Weapons of Mass Destruction Weapons of Mass Destruction After reading this article you will be able to: 1. 2. 3. 4. Define Weapons of Mass Destruction. Explain the different types of Warfare. Discuss the different delivery systems for each type of warfare. Discuss the routes of exposure to an attack of Weapons of Mass Destruction. September 11, 2001, is a day that will forever be infamous for heartbreak, tragedy, and an all too realthreat of terrorism within the formerly unbreakable United States. Not only were thousands of innocent citizens killed, but hundreds of emergency workers trying to help the wounded and save those in danger. This tragedy, as well as other terrorist incidents have brought new attention to the threat of Weapons of Mass Destruction. This non-traditional form of warfare is a bigger threat now than ever before. As EMS workers, education and preparedness are key elements to a successful response to a catastrophic attack of biological warfare. Weapons of Mass Destruction (WMD) are weapons designed to kill large numbers of people, usually civilians but also potentially military personnel. They are generally considered to be of limited military usefulness because their destructiveness is likely to trigger an extreme response. They are also known as weapons of indiscriminate destruction, weapons of mass disruption and weapons of catastrophic effect. WMDs are categorized into four distinct groups: Biological, Chemical, Nuclear, and Radiological devices. The threat is terrifying in that the attack is not obvious like traditional warfare of guns and loud explosions. While the attack could be a catastrophic blast, it could also be a silent but deadly release of a poisonous gas. The desired effect is to kill, but in addition to death, it is to strike panic among the entire community and the rest of the world. As EMS workers, it is important to have an understanding of the different types of WMDs so that the mechanism can be properly identified. Each type of warfare has different signs, symptoms, and treatment interventions. Toxicology In the event of an attack of a WMD, the emergency management personnel must understand the basic toxicology principals. The first principal is to be able to distinguish whether the effect is acute (sudden) or is the effect delayed. This will make a difference on how to set up a triage area and determine priority. Also, EMS personnel must understand the routes of exposure. These include: 1. 2. 3. 4. Inhalation Absorption Ingestion Through an open wound/Injection EMS personnel should have an understanding of how triage should be constructed, what appropriate field treatment is required and which hospitals are equipped to handle a mass casualty and have a necessary antidote. EMS Safety There is no single ensemble that provides first responders the "ultimate" WMD response protection; therefore, the EMS workers should cautiously approach each situation upon the guidance of medical control. As with all situations, the safety of the EMS worker always comes first. The EMS community must therefore carefully study the WMD response scenarios most likely to occur in their community and prepare to the best of their ability. EMS should never approach a suspicious situation or object without guidance from medical control and the proper protective gear. EMS workers should immediately evacuate the area until further direction. The last thing that the EMS workers want to do is disturb the possible weapon allowing for a bigger release or injury to themselves or more civilians. Biological Warfare A biological weapon uses a bacteria or virus or in some cases toxins to kill people. If you were to dump a load of manure or human waste into a town's well, that would be a simple form of biological warfare -- human and animal manure contain bacteria that are deadly in a variety of ways. Terrorism involving biological weapons is the least effective as far as mass murder, but is very cost effective and able to be spread in a discreet uncomplicated fashion. Biological weapons are referred to as “the poor man’s nuclear weapon.” This type of weapon can range from tainting a water or food supply, to an aerosolized release over a chosen area. Weapons Ideal characteristics of biological weapons are low visibility, high potency, accessibility, and easy delivery. Diseases most likely to be considered for use as biological weapons are contenders because of their lethality (if delivered efficiently), and robustness (making aerosol delivery feasible). The biological agents used in biological weapons can often be manufactured quickly and easily. The primary difficulty is not the production of the biological agent but delivery in an infective form to a vulnerable target. For example, anthrax is considered an excellent agent. First, it forms hardy spores, perfect for dispersal by aerosols. Second, pneumonic (lung) infections of anthrax usually do not cause secondary infections in other people. Thus, the effect of the agent is usually confined to the target. A pneumonic anthrax infection starts with ordinary "cold" symptoms and quickly becomes lethal. Finally, friendly personnel can be protected with suitable antibiotics or vaccines. A mass attack using anthrax would require the creation of aerosol particles of 1.5 to 5 microns. Too large and the aerosol would be filtered out by the respiratory system. Too small and the aerosol would be inhaled and exhaled. Also, at this size, nonconductive powders tend to clump and cling because of electrostatic charges. This hinders dispersion. So, the material must be treated with silica to insulate and discharge the charges. The aerosol must be delivered so that rain and sun does not rot it, and yet the human lung can be infected. There are other technological difficulties as well. The center for disease control has categorized the long list of biological weapons into three distinct categories. Category A, which are weapons most likely to be used. Category B, which is the second highest priority, and Category C, which are “emerging infectious disease threats.” Category A These are the weapons that are most likely to be used in a biological attack. They can do the most amount of damage in terms of death rates and how fast they can spread and be distributed. Examples of Category A weapons: Anthrax : Anthrax is a bacteria with a highly resistant spore form. It is highly infectious and lethal when inhaled. It is a one-time agent that does not spread from one person to another. An anthrax vaccine does exist but requires many injections and has enough side-effects that it is considered unsuitable for general use. Botulism: Botulism is one the deadliest toxins caused by a bacteria. Botulism causes respiratory failure and paralysis. Plague: Plague is a highly contagious bacteria. It causes a type of pneumonia and may be fatal. Smallpox : Smallpox is a highly contagious virus. It transmits easily through the atmosphere and has a high mortality rate. Smallpox was eliminated in the world in the 1970s thanks to a worldwide vaccination program. However, some virus are still available in Russian and American laboratories. It is also believed it could be available in other labs. Category B This form of biological weapons is the second-highest priority to the Center for Disease Control. They are fairly easy to spread, but cause only moderate amounts of disease and a low fatality rate. The diseases caused by category B’s are treatable if early detection is successful. Proper diagnosis requires specific public health action and aggressive treatment. Examples of Category B weapons: Q Fever: Q fever is found around the world and affects sheep, goats, cattle, dogs, cats, birds, rodents and ticks, as well as some other animals. Infected animals shed this bacteria in urine, feces, birth products and milk. Humans usually acquire Q fever by inhaling contaminated droplets excreted by infected animals. Viral Encephalitis: Viral encephalitis is inflammation of the brain caused by a virus. Some viral diseases, such as measles and rubella can also progress to involve inflammation of the brain. Other micro-organisms, such as bacteria, fungi and parasites are capable of triggering encephalitis. Typhus: Typhus also known as war fever has always been associated with war. Humans become infected by rubbing or scratching the feces of lice, mites, chiggers or fleas into their skin or into their mucous membranes. Category C This form of biological warfare is described as “emerging infectious disease threats.” They are the most easy to obtain and produce extremely high rates of mortality and disease. Examples of category C weapons: Hantavirus: Hantavirus is a deadly disease transmitted by infected rodents through urine, droppings, or saliva. Humans can contract the disease when they breathe in aerosolized virus. Nipah virus: Nipah virus was identified in 1999 when it caused an outbreak of neurological and respiratory disease on pig farms in peninsular Malaysia resulting in 105 human deaths and the culling of one million pigs. Other Types of Biological Agents Ebola: Ebola is a viral hemorrhagic fever. It is extremely lethal, with no cure. The symptoms are profuse bleeding from the orifices. Marburg: Marburg is a viral hemorrhagic disease. It is extremely lethal, with no cure. Tularemia: Tularemia is a bacteria, responsible for non-lethal but extremely incapacitating diseases (weight loss, fever, headaches, and often pneumonia). Agricultural Bioterrorism Another form of biological attack is to contaminate animals. This not only can kill our food supply by diseasing their drinking water or the grass they eat, but it can also cause death if diseased meat is processed and ingested by humans. An example of this is Mad Cow Disease. Delivery Systems Biological weapons are relatively easy to spread. They can be ingested, such as the successful contamination of food or water. They also can be aerosolized, which means they can be released into the air and contaminate people when they breathe. Many of the biological weapons can cause harm just by contact with human skin. Symptoms The signs and symptoms of biological warfare can include flu-like symptoms, exhaustion, pneumonia, weight loss, stomach pain, diarrhea, respiratory failure and shock. Treatment Biological weapons are not easily diagnosed. Usually patients do not exhibit the full extent of their problem until weeks or months after the initial exposure. Public health officials often can't pinpoint bio-terrorism right away because symptoms often mirror ones exhibited by a person with the common cold or the flu. In-hospital treatments include antidotes, antibiotics, vaccines and pumping of the stomach. EMS treatment usually just requires oxygen and transport, as it is not easily diagnosed in the field what exposure has occurred. Chemical Warfare A chemical weapon is any weapon that uses a manufactured chemical to kill people. The first chemical weapon used effectively in battle was chlorine gas, which burns and destroys lung tissue. Chlorine is not an exotic chemical. Most municipal water systems use it today to kill bacteria. It is easy to manufacture from common table salt. In World War I, the German army released tons of the gas to create a cloud that the wind carried toward the enemy. Modern chemical weapons tend to focus on agents with much greater killing power, meaning that it takes a lot less of the chemical to kill the same number of people. Many of them use the sorts of chemicals found in insecticides. When you spray your lawn or garden with a chemical to control aphids, you are, in essence, waging a chemical war on aphids. Chemical weapons are a little bit different in that there are known stockpiles of it through out the world. It is constantly questioned how secure it can be kept. It is highly desired by terrorist groups because it is easy to replicate, fairly cheap to obtain, has a violent instantaneous effect, and the supplies are inexpensive as well. It is believed that in the future chemical agents will be vastly pursued by terrorist organizations. It is widely believed that Al Queda, the terrorist network held accountable for the September 11 attacks, has actively tried to make their own chemical weapons. Weapons The most well known chemical agent is mustard gas. Chemical agents run in all types from blood agents, to respiratory agents, to choking agents. Nerve agents are the most toxic of the known chemical warfare agents. Depending on the type of nerve agent, they can be absorbed through the skin, respiratory tract, gastrointestinal tract and the eyes. Chemical Nerve Agents kill by disrupting the metabolic processes, causing a buildup of a chemical messenger (acetylcholine) by inhibiting the production of acetylcholinesterase, a key regulator of neurotransmission. Lethal exposure to chemical nerve agents is generally characterized by drooling, sweating, cramping, vomiting, confusion, irregular heart beat, convulsions, loss of consciousness and coma. Little is known, however, about the long term effects of nonlethal exposure. Blood agents were used to a limited extent in World War I. They are fast-acting, highly poisonous chemicals. Blood agents, sometimes referred to as Cyanides, affect an enzyme allowing the red blood cells to acquire oxygen, preventing the transfer of oxygen to other cells. Consequently, body tissue decays rapidly due to a lack of oxygen and retention of carbon dioxide, initially affecting the heart and then the brain. About 15 seconds after inhalation of concentrated vapor, abnormally deep breathing is followed in about 15 to 30 seconds by convulsions, with respiratory activity stopping about 2 to 3 minutes later. Subsequently, cardiac activity ceases several minutes later. Blister agents were initially used by Germany in World War I. Vesicants/blister gases first affect the eyes and respiratory tract when inhaled, along with reddening of the skin, followed by ulcerations and systemic poisoning. Death results from respiratory failure, bacterial pneumonia or immune system failure. There is no specific antidote and decontamination is the only way to reduce damage. Choking agents are the oldest known chemical warfare agents. Choking agents, such as Phosgene, irritate the alveoli in the lungs and cause the constant secretion of fluid into the lungs. As a result, the lungs slowly fill with fluid and the victim dies from the lack of oxygen. Choking agents are heavy gases and tend to stay close to the ground but tend to dissipate rapidly in a breeze. There is no antidote for choking agents. Skin and eye decontamination should be performed immediately after exposure. Sarin: A colorless and practically odorless liquid, Sarin dissolves well in water and organic solvents. The basic military use of Sarin is that of a gas and a persistent aerosol. A highly toxic agent with a clearly defined myopic effect, symptoms of intoxication appear quickly without any period of latent effect. Sarin has a cumulative effect, independent of its method of entry into the body. The progressive signs of initial Sarin intoxication include myosis (contraction of the pupil), photophobia, difficulty breathing and chest pain. Ricin: Ricin is a glycoprotein toxin from the seed of the castor plant. It blocks protein synthesis by altering the rRNA, thus killing the cell. Ricin's significance as a potential biological warfare agent relates to its availability world wide, its ease of production, and extreme pulmonary toxicity when inhaled. A Ricin paste can be placed on inanimate objects (Door knobs, steering wheels, etc...) and is a powerful contact poison. It was used with great success by KGB agents to eliminate their foreign counterparts during the cold war. Using an umbrella with a Hypo like device at its tip, an amount of Ricin the size of this [o] was injected into an unwary victim. (Usually a harmless "Bump and run" maneuver at a train or bus station.) Stymied by these patients rapid downward spiral, physicians could only watch as these people died within three to six days from an unknown etiology. A sharp medical examiner discovered the remnants of the tiny Ricin capsule imbedded in the leg of one such person-and the secret was out. People have been known to buy castor plants in order to improve their landscape-and do away with their significant other. All "reported" serious or fatal cases of castor bean ingestion have taken approximately the same course: rapid onset of nausea, vomiting, abdominal cramps and severe diarrhea with vascular collapse; death has occurred on the third day or later. Following inhalation, symptoms include weakness, fever, cough, hypothermia followed by hypotension and cardiovascular collapse. High doses by inhalation appear to produce severe enough pulmonary damage to cause death. Therapy is supportive and should include maintenance of intravascular volume. Standard management for poison ingestion should be employed if intoxication is by the oral route. There is presently no antitoxin available for treatment. Mustard Gas: A Blister Agent, which is a colorless, oily liquid that dissolves poorly in water, but relatively well in organic solvents, petroleum, lubricant products, and other toxic agents. The injurious effect of mustard gas is associated with its ability to inhibit many enzyme systems of the body. This, in turn, prevents the intra-cell exchange of chemicals and leads to necrosis of the tissue. Death is associated mainly with necrosis of the tissue of the central nervous system. Mustard gas has a period of latent effect (the first signs of injury appear after 2 to 12 hours), but does not act cumulatively. It does not have any known antidotes. In military use, it can come in gas, aerosol, and droplet form. It therefore acts through inhalation, cutaneously, perorally and directly through the blood stream. The toxic and physico-chemical properties of mustard gas allow it to be used in all types of munitions. Cyanogen Chloride: The French first suggested the use of cyanogen chloride as a toxic agent. U.S. analysts have reported that it is capable of penetrating gas mask filters. Partially soluble in water, it dissolves well in organic solvents. It is absorbed easily into porous materials; its military state is a gas. Cyanogen chloride is a quick acting toxic agent. Upon contact with the eyes or respiratory organs, it injures immediately. Lethal exposures result in loss of consciousness, convulsions and paralysis. Hydrogen Cyanide: There is some evidence that the World Trade Center bombers added cyanide to the bomb that blew up in the parking garage under that building, apparently in the hope of killing more people. This colorless liquid smelling of bitter almonds, hydrogen cyanide is a very strong, quick acting poison. Hydrogen cyanide affects unprotected humans through the respiratory organs and during the ingestion of contaminated food and water. It inhibits the enzymes which regulate the intra-cell oxidant-restorative process. As a result, the cells of the nervous system, especially those affecting breathing, are injured, which in turn leads to quick death. An important feature of hydrogen cyanide is the absence of a period of latent effect. The military state of hydrogen cyanide is as a gas. The toxic and physiologic properties of hydrogen cyanide permit it to be used effectively in munitions (predominantly in rocket-launched artillery). Death occurs after intoxication due to paralysis of the heart. Non-lethal doses do not cause intoxication. Delivery Systems Chemical warfare is especially dangerous in that it can be spread in a variety of ways. Inhalation, skin or eye contact is among the most common of desired delivery systems. Another popular way to spread chemical agents is through agricultural systems such as crop dusters or other sprayers. Chemical contamination can also occur through food and water contamination. An easy way to contaminate a large number of people is by opening an aerosol container in a busy area such as a subway or a park. Symptoms The signs and symptoms of chemical poisoning are easier for EMS workers to recognize. First of all, once on scene, the environment can give many indicators. For example, there may be an excessive amount of dead animals, an odd odor, an unexplainable film on everything, or more obvious, numerous dead human bodies. Unlike other types of poisoning, chemical poisonings can result in immediate death. The physical symptoms of chemical exposure are external as well as internal. They can range from burns and blistering of the skin and eyes, to coughing, respiratory distress, vomiting, nausea, excessive tiredness, involuntary defecation and or urination, seizures, excessive eye contraction or severe headache. Treatment Methods EMS can use to relieve suffering include dressing any exposed wounds such as burns. Pain medicine (if indicated), rinsing of the eyes if affected. In hospital treatment will include antibiotics and any known antidotes. Treatment is mainly supportive. Nuclear Warfare Perhaps the most feared and definitely the most deadly type of attack are those that involve nuclear war. Nuclear weapons produce devastating and long-term effects on human and animal life as well as the environments in which they live. These are the hardest and most complex of all types of weapons to make because of the critical nuclear elements. Plutonium and/or highly enriched Uranium make up most of a nuclear weapon and are very hard to come by, complex to understand, dangerous to work with and are very expensive. Traditional nuclear weapons are not the only threat. Officials are concerned terrorists might also target the world's nuclear power plants and supplies. It is estimated that a standard attack with known existing weapons can kill at least 250,000 people on impact and injure millions more. Current fears of nuclear war are mainly centered around India and Pakistan, two nations whose majority religions and histories, as well as a territorial dispute in Kashmir and mutual possession of substantial (though probably numbered in dozens rather than thousands) nuclear arsenals makes many extremely nervous. In the case of Pakistan, their unstable government and the threat of radical Islamists seizing power and thus control over the nuclear arsenal has raised additional fears, compounded by the fact that a senior member of the development program, Sultan Bashiruddin Mahmood, is a strong Taliban sympathizer. Another flashpoint which has analysts worried is a possible conflict between the United States and the People's Republic of China over Taiwan. Although economic forces have decreased the possibility of military conflict, there remains the worry that a move toward Taiwan independence could spin out of control. A third potential flashpoint lies in the Middle East, where Israel is thought to possess on the order of one hundred nuclear warheads (although this has never been officially confirmed). Israel has been involved in wars with its neighbors on numerous occasions, and its small geographic size would mean that in the event of future wars the Israeli military might have very little time to react to a future invasion or other major threat; the situation could escalate to nuclear warfare very quickly in some scenarios. In addition, there is the worry that so-called rogue states such as Iran and North Korea may acquire nuclear weapons. Nuclear terrorism by non-state organizations could well be more likely, as states possessing nuclear weapons are susceptible to retaliation in kind. Geographically-dispersed and mobile terrorist organizations are not so easy to discourage by the threat of retaliation. Furthermore, while the collapse of the Soviet Union ended the Cold War, it greatly increased the risk that former Soviet nuclear weapons might become available on the black market. Weapons Examples of nuclear weapons include: Atomic Bombs Hydrogen Bombs “Loose Nukes” “Suitcase Bombs” Delivery Systems One of the biggest fear boosters with Nuclear weapons is the fact that they are so incredibly deadly, but relatively small. Most nuclear weapons can fit in a truck or car. This creates fear in the possibility that a terrorist can launch an attack by simply driving into a large city and parking in a public area and then detonating the bomb. Many experts agree that this creates cause for much concern. However, it is more likely that if a nuclear bomb were detonated, it would be delivered in the form of a bomb or a missile dropped from a bomber plane. Another form of created nuclear war that is less obvious but just as deadly, is by targeting our nuclear power plants for attack. America has nuclear materials all over. There are always trucks carrying nuclear waste on the road. There are many nuclear power plants across the country and most hospitals have the service of nuclear medicine for certain testing. Symptoms As a first responder to a nuclear accident, more than likely at the point of impact there will be no survivors. However, victims that survive may exhibit vomiting, headache, extreme fatigue, weakness, burnt skin, and burning eyes. There are also long-term effects such as secondary infections, hair loss, excessive bleeding, birth defects and speech difficulty. Treatment It is imperative that EMS workers not approach any scene unless they have the go ahead from medical control and the scene is secure. If they are able to approach the scene to aid, any clothes the victim is wearing must be removed immediately and placed in a sealed, locked, air tight container. The patients must then be washed completely with soap and water. This must be completed before the patient can enter the ambulance or the hospital. In some instances stomach pumping is necessary, as are laxatives. This intervention is to limit the amount of nuclear material into the bloodstream and cells of the exposed patient. Treatment is mostly supportive. Radiological Warfare Radiological warfare is any form of warfare involving deliberate radiation poisoning, without relying on nuclear fission or nuclear fusion. It is widely believed that if the United States were under an attack, it would be in the form of radiological warfare. This would be the weapon of choice for the terrorists for many reasons. Unlike most weapons, radiological weapons spread their wrath onto everyone and everything. They actually spread radioactive material onto equipment, facilities, food, land, and acts as a toxic chemical. It is in many cases fatal, but it also causes various forms of cancer and a variety of illnesses. Radiological weapons are normally considered weapons of mass destruction, and are very commonly equated with a radiological bomb often mis-called a "dirty bomb" (which refers to a nuclear weapon with a radiological side effect. However, bombs are very inefficient ways to spread radiation, and all such special weapons have problems that render them likely impractical for military uses. Rather, radiological warfare would be of vastly more use to terrorists spreading or intensifying Fear, Uncertainty, and Doubt. The release of radioactive material may involve no special "weapon" and include no direct killing of people, but rather make whole areas or structures unusable or doubtfully useful for the support of human life, due to the exposures of staying too near them for long periods. For instance, a city such as Washington DC could perhaps be rendered uninhabitable or at least quite undesirable radiation being extraordinarily difficult to remove once it is released into the built environment, and perhaps taking a long time to fully decay in the natural environment. Like land mines, it can be an area-denial method. Weapons A radiological weapon is any weapon that is designed to spread radioactivity, either to kill or to deny the use of an area (a modern version of salting the earth) and consists of an device (such as a nuclear or conventional explosive) which spreads radioactive material. They have recently been called "dirty bombs", although that term more correctly refers to a type of nuclear weapon. Radiological weapons are widely considered to be militarily useless for a governmentsponsored army and are not believed to have been deployed by any military forces. Firstly, the use of such a weapon is of no use to an occupying force, as the target area becomes uninhabitable. Furthermore, area-denial weapons are generally of limited use to an attacking army as it slows the rate of advance so the need for a radioactive denial system is limited. Finally, like biological weapons, radiological weapons can take days to act on the opposing force. They therefore not only fail in neutralizing the opposing force instantly, but they also allow time for massive retaliation. Means of radiological warfare that do not rely on any specific weapon but rather on spreading radiation poisoning via a food chain or water table, seem to be more effective in some ways but to share problems with chemical warfare. History has proven Iraq under the rule of that Saddam Hussein tested a radiological weapon in 1987 for use against Iran. This weapon was found to be impractical because the radioactive isotopes in the weapon would decay quickly, rendering it useless within a week after the weapon was manufactured. Furthermore, it was found that for the radioactive material to spread, weather conditions had to be ideal. These problems are shared by all forms of air-borne radiological warfare. Useless as they may be to an ordinary military force, the weapons have been suggested as a possible terror weapon in order to create panic in densely populated areas. They do not require weapons-grade materials and common materials such as Cesium-137 used in radiological medical equipment, could be used. In fact even very mild sources would likely be enough to cause panic. Anything from dynamite to compressed air could be used to create an aerosol of the material or it could be dumped from the air using crop dusters - the latter use however being not a weapon so much as a means of warfare involving many different components. Delivery Systems One difference in a dirty bomb versus the other types of warfare is that radioactive material is not usually dissolvable in water. Therefore, that eliminates contamination of the water supply or reservoirs through direct contamination. Methods of detonating a dirty bomb include artillery shells or explosives. Symptoms The symptoms of radiological poisoning can range widely. They can result in cancer or death or just cause mild skin reddening. One of the most common deadly result of radiation poisoning in called Acute Radiation Syndrome (ARS) which is defined as a high dose of radiation in a small amount of time which results in nausea, vomiting and diarrhea. Later, post-exposure, ARS can result in bone loss, loss of appetite, flusymptoms, severe infection and bleeding. EMS workers should always be suspicious of material that seems to emit heat without any sign of external heating source, as well as any glowing materials or particles. If the package is glowing this indicates a strong radioactive substance. If you ever come upon a suspicious package, leave the area immediately. Treatment EMS should properly decontaminate the victim, provide o2 and transport. Radiation victims should take off their clothes and wash with soap and water. Hospital workers will provide treatment depending on the amount of radiation received. Treatment is mostly supportive. Triage While biological warfare is a concern for many reasons, how to triage is a huge concern. The threat of a weapon of mass destruction attack is bigger now than ever before. While our government is on high alert for suspicious activity related to possible terrorism, the possibility of an attack is very real. The reality then becomes that the burden at the point of an attack will lie on the shoulders of the EMS workers. As EMS workers, you must be able to recognize the different weapons as well as how to keep yourself safe and how to properly treat the victims. The first five steps to triage a suspected terrorist attack remain constant and are similar to a mass casualty not of a terrorist type. The first steps that must be taken involve: 1. 2. 3. 4. Assess the immediate area and determine the incident. Scene Control/establishment of perimeters. Proper identification of the agent. Pre-entry exam and determination of appropriate protective clothing & equipment. 5. Establishment of a decontamination area 6. Entry planning/preparation of equipment The triage process is slightly different with a terrorist biological attack as opposed to a mass casualty such as a bus wreck because the threat to the EMS workers is greater. When dealing with any suspected terrorist attack, the first and most important task after the initial assessment is to secure the area and determine how and where the perimeters should be set. While physically securing the area, the EMS worker should also consider what the possible source of the threat is and how severe the outcome could be. Any suspicious activity or objects are cause for immediate concern as terrorist threats have included secondary attacks to specifically target the EMS worker. With a release or attack with a biological agent, a primary and a secondary perimeter need to be established. An immediate priority needs to be a thorough search of both perimeters for suspicious people, packages, or any activity that should not be happening post evacuation. Also, it is imperative during this phase that the wind is considered. Especially in the event of a chemical or biological attack, considering the downwind must be immediately addressed. For example, EMS would not want to set up triage in an area that the wind is carrying the attacking agent. Also, if the wind is blowing towards a populated area, that area should be immediately evacuated to avoid any more casualties. Identify the Problem A major problem in the war against terrorism and the constantly pressing problem of an attack with a harmful agent of any sort is that of the ability of EMS workers to identify what specifically the problem is. As is the case in most common industrial hazardousmaterials accidents, the first priority in the management of the incident involves ascertaining the identity and physical properties of the substance that has been released. Once this has occurred, then the EMS workers collectively can determine the best route to properly protect the environment. For example, it must be identified so that the triage area is set up properly and so that the EMS workers are dressed in appropriate protective gear. It is only after the proper identity is determined that an effective outer perimeter can be established, neutralizations plans formulated, decontamination procedures entertained, emergency medical treatment plans made and environmental preservation precautions taken. The question then becomes, how do EMS workers perform field-testing to determine what is in the air? This is one of the biggest concerns of this problem and threat. The fact is, that most civilian EMS agencies, even with sophisticated biohazard response teams, do not have the equipment necessary to properly identify a harmful agent. This issue is of the most serious consideration because unless the WMD are properly identified none of the appropriate actions can take place to set up a triage or to distinguish the proper perimeters. It is currently widely suggested that federal funding be made available to the local agencies that are providing the EMS service to ensure that the EMS workers are properly trained to test and identify a potential attack of chemical or biological warfare. They need funding for the training as well as the expensive monitoring and detection devices. Of course, the first priority of the EMS worker is to ensure his or her own safety first and foremost.
