4.1 Classification of human land search and rescue resources is based upon the training of the personnel and their ability to perform specific tasks.4.2 Human search and rescue resources are classified by category, kind, and duration.1.1 This classification is intended to identify the common functional units and single resources used in search and rescue operations; to aid search and rescue (SAR) managers and Authorities Having Jurisdiction (AHJs) in assembling or ordering resources for search, rescue, or search and rescue incidents; and to aid in identifying the tasks for which crews have been trained.1.2 This classification is intended as a supplement to the resource typing specifications of the Incident Command System and specifically as a means of typing human resources used in land search and rescue activities.1.3 This classification is suitable for classifying search and rescue crews for land search and rescue incidents.1.4 This classification does not attempt to classify individuals or put forth standards of performance or training for individuals, nor is it meant to convey certification, skill proficiency, or other measures of the level of performance of the resource. These qualifications are the responsibility of the local agencies responsible for utilizing the resource.1.5 This classification identifies human-based resources. Canine crew (or team) classifications are defined in Classification F1848.1.6 This classification does not classify air resources (Guides F2958 and F3026) or water resources (Guides F1739, F1783, and F1824).1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

1.1 This specification provides the format and guidelines for producing a catalog of current resources of air medical transport units, showing the patient care capability of each, in standard form.1.2 This specification applies to all the air transports involved in patient care that meet one or more applicable ASTM medical transport unit specifications.1.3 This specification incorporates only the information that is considered essential for use by the planners during an emergency. The intent is to provide information on what is available, what level of care it can provide, where it is, and the earliest it can respond, so that the most efficient use can be made of each unit, in accordance with the emergency plans.1.4 Information contained in the unit's operations manual, such as the weight and balance calculations for the "Specialized Medical Resources" listed in Appendix X1, is not included in the catalog but it will be available to the planners, on request.

5.1 Traditional methods for expressing geological uncertainty consist of preparing reliability categories based simply on the distance between drill hole data points, such as the one described by Wood et al. (5) that uses only the drill holes within the coal bed. A major drawback of distance methods is their weak to null association with estimation errors. This practice provides a methodology for effectively assessing the uncertainty in coal resource estimates utilizing stochastic simulation. In determining uncertainty for any coal assessment, stochastic simulation enables consideration of other important factors and information beyond the geometry of drill hole locations, both in and out of the coal bed, including: non-depositional channels, depth of weathering, complexity of seam boundaries, coal seam subcrop projections, and varying coal bed geology for different seams due to fluctuating peat depositional environments. Olea et al. (6) explains in detail the methodology behind this practice and illustrates it with an example.5.2 For multi-seam deposits, uncertainty can be expressed on an individual seam basis as well as an aggregated uncertainty for an entire coal deposit.5.3 The uncertainty is expressed directly in tons of coal. Additionally, this practice allows the statistical analysis to be presented according to widely-accepted conventions, such as percentiles and confidence intervals. For example, there is a 90 % probability that the actual tonnage in place is 314 million metric tons ± 28.8 million metric tons (346 million tons ± 31.7 million tons) of coal.5.4 The results of an uncertainty determination can provide important input into an overall risk analysis assessing the commercial feasibility of a coal deposit.5.5 A company may rank coal resources per block (cell) based on the degree of uncertainty.1.1 This practice covers a procedure for quantitatively determining in-place tonnage uncertainty in a coal resource assessment. The practice uses a database on coal occurrence and applies geostatistical methods to model the uncertainty associated with a tonnage estimated for one or more coal seams. The practice includes instruction for the preparation of results in graphical form.1.2 This document does not include a detailed presentation of the basic theory behind the formulation of the standard, which can be found in numerous publications, with a selection being given in the references (1-3).21.3 This practice should be used in conjunction with professional judgment of the many unique aspects of a coal deposit.1.4 Units—The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.NOTE 1: All values given in parentheses after SI units are stated in inch-pound units.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
