This application also describes methods of teaching hazardous material responders how to use the method of responding to a hazardous material based upon properties of the hazardous material based on its name.

## Background
BACKGROUND OF THE INVENTION
First responders must make rapid decisions in life-saving and life-threatening situations when dealing with hazardous materials that have been improperly released into the environment. This is especially true now with the threat of international terrorism. Prior to dealing with an actual terrorist or other incident involving suspected or known chemical hazards, emergency personnel must be adequately trained to properly react to the various types of hazardous events, for both their safety as well as public safety.
Given this, the incident commander must rapidly process information during a hazardous incident and make the appropriate decisions for action based upon his own cognitive abilities to mentally process such information with or without the help of subordinates. Although training manuals and field manuals may be available, timely access and processing of this information remains elusive, and decisions made on this less-than-optimal information may prove detrimental. Importantly, the known detection methods give the responder a variety of information, however the key is to understand is what you are using and why and to have a quick and efficient method of risk assessment of an chemical incident in minutes.
Hazardous Material (HazMat) Responders experience “information overload” that often results in responders over analyzing available research material causing incidents to be time-consuming, extremely costly, and labor intensive. Implementing change in existing methods to make efficient risk based decisions on virtually any chemical incident in minutes creates tremendous opportunities and dramatic challenges, often concurrently. There exists a need in the art for novel methods of quick risk assessment of chemical incident in the civil and combat situations. There is a need to integrate the required functional elements in order to respond adequately to a terrorist threat or chemical incident involving suspected or known chemical hazards.
The description herein of disadvantages and problems associated with known methods is in no way intended to limit the scope of the embodiments described in this document to their exclusion. Indeed, certain embodiments may include one or more known methods or method steps without suffering from the so-noted disadvantages or problems.

DETAILED DESCRIPTION OF THE INVENTION
Before the present methods are described, it is understood that this invention is not limited to the particular methodology, protocols, and reagents described, as these may vary. It also is to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present invention that will be limited only by the appended claims.
Definitions
For the purposes of promoting an understanding of the embodiments described herein, reference will be made to preferred embodiments and specific language will be used to describe the same. The terminology used herein is for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present invention. As used throughout this disclosure, the singular forms “a,” “an,” and “the” include plural reference unless the context clearly dictates otherwise. Thus, for example, a reference to “a chemical” includes a plurality of such chemicals, as well as a single chemical.
As used herein, the following acronyms have the following meanings: LEL for Lower Explosive Limit; UEL for Upper Explosive Limit; Fl.P for Flash Point; IDLH for Immediately Dangerous to Life and Health; IP for Ionization Potential; MW for Molecular weight; HazMat for Hazardous Materials; and ER for Exposure Routes.
The explosive limit of a gas or a vapor, is the limiting concentration (in air) that is needed for the gas to ignite and explode. There are two explosive limits for any gas or vapor: the lower explosive limit (LEL) and the upper explosive limit (UEL). At concentrations in air below the LEL there is not enough fuel to continue an explosion; at concentrations above the UEL the fuel has displaced so much air that there is not enough oxygen to begin a reaction.
Personal Protection Equipment (PPE) is used by HazMat responders when they are called to respond to a HazMat emergency. There are three levels of PPE commonly used by HazMat responders; Turnout gear, Level A, and Level B. Turnout gear is equipment usually used by firefighters when responding to a fire. Turnout gear generally includes waterproof and otherwise protective jacket and pants as well as a helmet. Level A is used when the greatest level of skin, respiratory, and eye protection is required. Level A equipment may include, but is not limited to, the following: a positive pressure, full face-piece self-contained breathing apparatus (SCBA), or positive pressure supplied air respirator with escape SCBA; a totally-encapsulating chemical-protective suit including coveralls, long underwear, gloves and boots; a hard hat and optionally a disposable protective suit, gloves and boots which may be worn over totally-encapsulating suit. Level B provides the highest level of respiratory protection is necessary but a lesser level of skin protection. Level B equipment may include, but is not limited to, the following: a positive pressure, full face-piece self-contained breathing apparatus (SCBA), or positive pressure supplied air respirator with escape SCBA; hooded chemical-resistant clothing including overalls and long-sleeved jacket; coveralls; one or two-piece chemical-splash suit; and optionally disposable chemical-resistant overalls; gloves; boots; boot-covers; a hard hat and face shield.
The HazMat Response System
FIG. 1 shows a schematic summarizing how the HazMat Response System of the invention works. If the chemical name of the material being analyzed is known, then the system is used as represented from the left side of the schematic. If not, it is begun at the right side of the schematic. We first describe how the HazMat Response System works when the chemical name is known.
As shown in FIG. 1, the first step is to use the information conveyed by the proprietary “Smart Chart” of the HazMat Response System of the invention. (FIG. 2). In one embodiment, this information is contained in the “Smart Chart” as shown in FIG. 2. In other embodiments, this information is contained in other fixed media allowing a HazMat responder to quickly determine at the scene of a HazMat emergency if the material is “above the line” or “below the line”. An example of one other such fixed medium is shown in FIG. 3. These fixed media are also able to be used electronically. Thus, these representations of elements and chemical moieties being above and below the line are also shown on computer, cell phone or personal digital assistant (PDA). These fixed media need not separate all of the listed elements into two groups. In some embodiments of the invention, only the most commonly encountered elements and/or chemical moieties need to be represented in the fixed medium. The fixed medium may list any number of elements from two elements or fixed moieties to all of them. Examples of numbers of elements of moieties represented include 2, 5, 10, 15, 20, 25, 50, 60, 70, 80, 90 and 100.
The “line” is indicated on the periodic table of elements shown in FIG. 2. The materials with elements in their first names, shown below the heavy marking, are considered “below the line”. Also materials that have one of the four chemical moieties in the diamond above the periodic table of elements in their second name are also considered “below the line”. The elements that are considered “below the line” are lithium, sodium, potassium, rubidium, cesium, beryllium, magnesium, calcium, strontium, barium, scandium, yttrium, lanthanum, titanium, zirconium, hafnium, vanadium, nobelium, tantalum, chromium, molybdenum, tungsten, manganese, technetium, rhenium, iron, ruthenium, osmium, cobalt, rhodium, iridium, nickel, palladium, platinum, copper, silver, gold, zinc, cadmium, mercury, aluminum, gallium, indium, thallium, germanium, tin, lead, antimony, bismuth, and polonium. The chemical moieties that are considered “below the line” are nitride (ammonia), carbide (acetylene), hydride (hydrogen) and phosphide (phosphine). Materials that are classified as “below the line” include those that, generally, are solid at room temperature, are non-flammable, have no LEL or UEL, have no flashpoint, no ionizing potential, and are bases. For these materials, the units used to measure their exposure limits e.g. their immediately dangerous to life and health (IDLH) level or permissible exposure limits (PELs) are mg/m3. The materials with elements in their first name, shown above the heavy marking, are considered “above the line”. The elements that are considered “above the line” are hydrogen, boron, carbon, silicon, nitrogen, phosphorus, arsenic, oxygen, sulfur, selenium, tellurium, fluorine, chlorine, bromine, iodine, astatine, helium, neon, argon, krypton, xenon, and radon. Materials that are classified as “below the line” include those that are liquids or gases, are flammable, have LEL and UEL, a flashpoint, an ionizing potential and are acids. For these materials, the units used to measure their exposure limits e.g. their immediately dangerous to life and health (IDLH) level or permissible exposure limits (PELs) are parts per million (ppm).
Based on the information provided by a material being classified as above or below the line, personnel responding to a HazMat situation can quickly determine the initial PPE necessary for the material. If a material is classified as “above the line” a Level B PPE is generally necessary, while with materials classified as “below the line” a Level A PPE is generally necessary. Moreover, the initial isolation zone for a material classified as “above the line” is generally a 75 feet radius, while a material classified as “below the line” generally has an initial isolation zone of a 150 feet radius if it is a liquid and of 300 feet if it is a gas.
Additional information can then be acquired to deal with the hazardous material after a perimeter has been created. For example, for materials classified as “above the line” additional tests can be performed based on the ending of the second name of the material. FIG. 4 shows tests that are used to detect the concentration of hazardous material and the associated hazard. These tests include potassium iodide (KI) tests to detect oxidants, tests of pH, tests for toxic industrial chemicals (TIC), tests involving photoionization detectors (PID), flame ionization detectors (FID), tube chips used to detect various biological hazards, and combustible gas indicators (CGI). For materials classified as “below the line” different tests can be performed based on the ending of the second name of the material. FIG. 5 shows tests that are used to detect the concentration of hazardous material and the associated hazard.
In other embodiments of the HazMat Response System of the invention, the four step system can be used in reverse if the name of the compound is not known. Upon entering a the site of a HazMat emergency, a HazMat responder may not know what the hazardous material is, and whether it is above or below the line. Because of the differences between hazardous materials that are above or below the line, a HazMat responder can perform any one of a number of simple tests to determine whether a hazardous material is a solid or gas. If the HazMat is a solid then Level A PPE should be used to protect HazMat responder personnel, whereas with a gas or liquid, Level B is used. The tests shown above in FIGS. 3 and 4 can be used to ascertain what hazardous material is present and what sort of response should be made to the hazardous material.
The invention also provides methods of training HazMat responders to use the HazMat Response System of the invention. The training includes familiarizing HazMat responders with the fixed media that are used to quickly ascertain whether a hazardous material is “above” or “below the line”. This familiarization is performed by providing for the HazMat responders to be trained a copy of one or more fixed media used to quickly ascertain whether a hazardous material is “above” or “below the line” and instructing them how to use the media. These fixed media can be any of those described herein, including representations as shown in FIGS. 2 and 3. The training further includes familiarizing HazMat responders with fixed media showing selected physical properties of hazardous materials and tests that should be performed to characterize the threat posed by these materials. Examples of such fixed media are shown in FIGS. 4 and 5, herein.

Determination of Hazard Information for Hazardous Materials
The HazMat Response System of the invention is used to respond to any hazardous material. Below, example of various materials and how the system indicates to respond to them are shown.
Calcium oxide would be considered to be “below the line” using the HazMat response system of the invention, because the name “calcium” is in the first name of the material. This shows to a HazMat responder that this material is a solid, it is not flammable, it has no LEL, it has no flashpoint or ionization potential, it is a base, the IDLH or PEL is measured in mg/m3 and that the initial isolation is 75 feet. Based on having “oxide” in the second name of the material, the HazMat responder would also know to test pH because the material generally acts as a weak base. (FIG. 4). The HazMat responder would also know to use a PPE of Level B.
Potassium cyanide would also be considered to be “below the line” using the HazMat response system of the invention, because the name “potassium” is in the first name of the material. As above, for calcium oxide, this shows to a HazMat responder that this material is a solid, it is not flammable, it has no LEL, it has no flashpoint or ionization potential, it is a base, the IDLH or PEL is measured in mg/m3 and that the initial isolation is 75 feet. Based on having “cyanide” in the second name of the material, the HazMat responder would also know to test pH, test with a tube chip and CGI to determine the amount of potassium cyanide present because of the toxicity of the substance. (FIG. 4). The HazMat responder would also know to use a PPE of Level B.
Vinyl chloride would be considered to be “above the line” using the HazMat response system of the invention, because the name “vinyl” is not one of the names present “below the line”.
