InfoGram
February 5, 2004
NOTE: This InfoGram will be distributed weekly to provide members of the emergency management and response sector with information concerning the protection of their critical infrastructures. It has been prepared by NATEK Incorporated for the Emergency Preparedness and Response Directorate. For further information, contact the Emergency Management and Response - Information Sharing and Analysis Center (EMR-ISAC) at (301) 447-1325 or by email at emr-isac@fema.dhs.gov.
Ricin Response Preparedness
The recent discoveries of ricin are sobering reminders that American citizens remain vulnerable to domestic and/or transnational extremists who decide to disrupt the nation's daily routine. Positive confirmation of this toxic powder forced the quarantine and decontamination of several U.S. Senate staff workers, and placed many on alert for any unusual symptoms during the past few days. It additionally required the closing of approximately three government buildings and triggered a major reaction by federal and local agencies.
Ricin is a poisonous substance that can be made from the waste left over from processing castor beans. It can be in the form of a powder, a mist, a pellet, or it can be dissolved in water or weak acid. The poison is only minimally affected by extreme conditions such as very hot or very cold temperatures.
The Centers for Disease Control (CDC) and National Institute of Occupational Safety and Health (NIOSH) offer recommendations for emergency personnel responding to suspected ricin incidents. The recommendations for personal protective equipment, including respiratory protection and protective clothing, are based upon the anticipated level of exposure risk associated with different response situations. Although personnel should first refer to and follow local HAZMAT protocols for this type of substance, the CDC/NISOH recommendations are summarized as follows:
- Personnel should use NIOSH approved, positive pressure breathing apparatus (SCBA) in conjunction with Level A protective suits when responding to a suspected biological incident where any of the following information is unknown or the event is uncontrolled:
- type(s) of airborne agent(s)
- dissemination method
- duration of dissemination
- exposure concentration
- Personnel may use Level B protective suits with an exposed or enclosed NIOSH approved, positive pressure SCBA in the following situation:
- the suspected airborne agent is no longer being generated
- other conditions may present a splash hazard
- Personnel may use a full-face piece respirator with a P100 filter or powered air-purifying respirator (PAPR) with high efficiency particulate air (HEPA) filters when it can be determined that:
- an aerosol-generating device was not used to create high airborne concentration
- dissemination was by means of a letter or package that can be easily bagged

Pressures Cookers: A Threat?
The Department of Homeland (DHS) issued an Information Bulletin on 4 February to alert frontline border inspectors, state and local officials, and emergency first responders of the continued interest by terrorist organizations to use innocuous items to package improvised explosive devices (IEDs). A technique commonly taught in Afghan terrorist training camps is the conversion and use of pressure cookers as an IED.
To make such a bomb the terrorist will place TNT or other explosives into a pressure cooker and attach a blasting cap at the top of the airtight utensil. The size of the blast depends on the size of the pressure cooker and the amount of explosives inserted within. Pressure cooker bombs are made with readily available materials and can be as simple or as complex as the bomber decides. Unfortunately, because it is a common cooking utensil throughout the world, the pressure cooker is often overlooked when searching vehicles crossing borders and the residences of suspected terrorists.
DHS suggests the following protective measures for personnel who might come into contact with questionable pressure cookers:
- Don't move any pressure cooker weighing more than expected for its size.
- Don't transmit radio signals within 50 feet of the cooking utensil.
- Turn off cell phones and pagers within 50 feet of the pressure cooker.
- Evacuate personnel at least 150 feet from the immediate area of an indoor device.
- Evacuate personnel at least 1,850 feet from the immediate area of an outdoor device.
- Keep evacuated personnel out of direct line of sight and behind adequate cover.
Emergency Response Allies
Most leaders of the fire and emergency medical services practice outstanding vertical and horizontal coordination to produce results with benefits for the personnel, physical assets, and communication systems of their departments. These leaders have successfully learned the proactive human relations skills necessary to acquire the cooperation and support of key allies in the protection of their organization's critical infrastructures. They have personally experienced that relationship building will significantly help to reduce some of the obstacles to the protection of their critical infrastructures.
The EMR-ISAC hears a common theme when speaking to some of these fire/EMS senior leaders. They frequently recommend that the chief officer in each department develop strong professional relationships with their counterparts in other local agencies. The EMR-ISAC reminds that relationship building must be a never-ending evolution, which constantly seeks perfection.
The following activities or agencies are most often mentioned as essential allies to formulate a united front for the protection of community and emergency response critical infrastructures:
- Municipal Government/Governing Council
- Law Enforcement
- Public Health and Safety
- Medical Departments
- Public Utilities/Services/Works
- Mass Transportation
- Emergency Communications
FEMA Building Guides Available
A series of four new FEMA publications offer guidance on designing, engineering, and constructing high-occupancy buildings that are more resistant to damage from terrorist attacks. These resources were developed to make American communities aware of science and technology that can be used to protect people and critical infrastructures from the effects of these attacks on structures such as schools and commercial buildings.
As part of the Multi-Hazard Risk Management Series, the publications supplement a previously issued FEMA guide on integrating human-caused hazards into mitigation planning and are targeted for public policy officials, emergency managers, facility owners and managers, architects and building construction professionals.
The publications are free and can be downloaded from FEMA's website at: http://www.fema.gov/fima/rmsp.shtm. They can be ordered through the FEMA publication distribution center by calling 1-800-480-2520.
HSAS Preparedness Guide
The new Fire and Emergency Services Preparedness Guide for the Homeland Security Advisory System (HSAS) offers suggestions for activities that may be appropriate for the five HSAS levels.
