A non-transitory computer-storage medium storing computer-executable instructions that, when executed, cause a computer system to perform a computer-implemented method comprising:
- determining the presence of at least one hazardous material based at least in part on digital comparisons of at least one digital representation associated with at least one user defined selection from a displayable list and a plurality of records associated with a plurality of hazardous materials, the plurality of records being a data set stored in a database, each record of the plurality of records associated with a hazardous material associated with at least one of normalized descriptors of observable properties or normalized symptoms of exposure, the plurality of records including at least one stored record associated with the at least one hazardous material, the at least one stored record having digital information associated with at least one of normalized descriptors of observable properties of the at least one hazardous material or normalized symptoms of exposure to the at least one hazardous material and comprising a bit sequence common to the plurality of records associated with plurality of hazardous materials, the normalized descriptors based on parsing, classification, and normalization of plain language descriptions of the observable properties and the normalized symptoms based on parsing, classification, and normalization of plain language descriptions of the symptoms, wherein the plain language descriptions of observable properties and the plain language descriptions of symptoms are not normalized,
- wherein the at least one stored record having digital information is further associated with at least one special modifier that describes at least one normalized descriptor of the normalized descriptors of observable properties of the at least one hazardous material or the at least one hazardous material,
- wherein each record of the plurality of records is associated with a hazardous material and a corresponding bit sequence, each bit of at least a portion of the bit sequence representing a particular normalized descriptor of an observable property, a particular special modifier that describes a normalized descriptor of the hazardous material or the hazardous material, or a particular normalized symptom of exposure associated with the hazardous material, and a value of the bit indicating a presence or absence of the particular normalized descriptor, the particular special modifier, or the particular normalized symptom,
- wherein each bit of the portion of the bit sequence representing a particular normalized descriptor is associated with a presence or absence of a color, a texture, or an odor,
- wherein each bit of the portion of the bit sequence representing a particular normalized symptom is associated with a presence or absence of a sign or symptom relating to appearance, cardiovascular, eyes, respiratory, skin, behavior, digestive system, and temperature;
- providing for presentation to a first responder associated with a hazardous material emergency an indication of the at least one hazardous material for selection and response information including at least one of an Emergency Response Guide, isolation distance, or reactive groups;
- determining a controlled substance of which a selected hazardous material is a chemical precursor;
- and
- providing for presentation the controlled substance to the first responder associated with the hazardous material emergency.
