However, no soil is Type A if: (ii) The soil is subject to vibration from heavy traffic, pile driving, or similar effects; or, (iii) The soil has been previously disturbed; or, (iv) The soil is part of a sloped, layered system where the layers dip into the excavation on a slope of four horizontal to one vertical (4H:1V) or greater; or.
Soil classification system means, for the purpose of this subpart, a method of categorizing soil and rock deposits in a hierarchy of Stable Rock, Type A, Type B, and Type C, in decreasing order of stability. (4) Layered systems. 
Get answer to your question and much more. The categories are determined based on an analysis of the properties and performance characteristics of the deposits and the environmental conditions of exposure. Cohesive soil is hard to break up when dry, and exhibits significant cohesion when submerged. Type C soils with an unconfined compressive strength of 0.5 tsf can be easily penetrated several inches by the thumb, and can be molded by light finger pressure. Examples of cohesive soils are: clay, silty clay, sandy clay, clay loam and, in some cases, silty clay loam and sandy clay loam. (iii) Thumb penetration.

Each soil and rock deposit shall be classified by a competent person as Stable Rock, Type A, Type B, or Type C in accordance with the definitions set forth in paragraph (b) of this appendix. This appendix applies when a sloping or benching system is designed in accordance with the requirements set forth in 1926.652(b)(2) as a method of protection for employees from cave-ins. (iii) Observe the side of the opened excavation and the surface area adjacent to the excavation. Such analyses shall be conducted by a competent person using tests described in paragraph (d) below, or in other recognized methods of soil classification and testing such as those adopted by the America Society for Testing Materials, or the U.S. Department of Agriculture textural classification system. (iii) Previously disturbed soils except those which would otherwise be classified as Type C soil. Cemented soil means a soil in which the particles are held together by a chemical agent, such as calcium carbonate, such that a hand-size sample cannot be crushed into powder or individual soil particles by finger pressure. It can be determined by laboratory testing, or estimated in the field using a pocket penetrometer, by thumb penetration tests, and other methods. Wet soil means soil that contains significantly more moisture than moist soil, but in such a range of values that cohesive material will slump or begin to flow when vibrated. Estimates of unconfined compressive strength of soils can also be obtained by use of a pocket penetrometer or by using a hand-operated shearvane. The ___________ is responsible for the publishing and maintaining HCPCS Level II. This preview shows page 1 - 2 out of 2 pages. Soil that remains in clumps when excavated is cohesive. (vi) Material that is part of a sloped, layered system where the layers dip into the excavation on a slope less steep than four horizontal to one vertical (4H:1V), but only if the material would otherwise be classified as Type B. Cemented soils such as caliche and hardpan are also considered Type A. (ii) Dry strength. (2) Application. Course Hero is not sponsored or endorsed by any college or university. Soil that is primarily composed of finegrained material is cohesive material. (5) Reclassification. USA.gov, The U.S. National Archives and Records Administration Mold a moist or wet sample of soil into a ball and attempt to roll it into threads as thin as 18-inch in diameter. WHO defines ___________ as a reference classification? This test should be conducted on an undisturbed soil sample, such as a large clump of spoil, as soon as practicable after excavation to keep to a minimum the effects of exposure to drying influences.
This appendix describes a method of classifying soil and rock deposits based on site and environmental conditions, and on the structure and composition of the earth deposits. Want to read all 2 pages? Examine layered systems to identify if the layers slope toward the excavation. (iv) Observe the area adjacent to the excavation and the excavation itself for evidence of existing utility and other underground structures, and to identify previously disturbed soil. (C) If a sample breaks easily by hand, it is either a fissured cohesive material or a granular material. Moist cohesive soil can easily be shaped into a ball and rolled into small diameter threads before crumbling. Granular soil has no cohesive strength. A. Clair Johnson has presented to the healthwise hospital emergency department with gallbladder pain and is being admitted for gallbladder removal surgery. Granular soil means gravel, sand, or silt, (coarse grained soil) with little or no clay content. (v) The material is subject to other factors that would require it to be classified as a less stable material. If you were looking for a code for a medication taken orally, in which system is it found? (2) Basis of classification.
Cohesive soil does not crumble, can be excavated with vertical sideslopes, and is plastic when moist. However, each layer may be classified individually where a more stable layer lies under a less stable layer. If the soil is dry and falls into clumps which break up into smaller clumps, but the smaller clumps can only be broken up with difficulty, it may be clay in any combination with gravel, sand or silt. If the soil is dry and crumbles on its own or with moderate pressure into individual grains or fine powder, it is granular (any combination of gravel, sand, or silt).
If, after classifying a deposit, the properties, factors, or conditions affecting its classification change in any way, the changes shall be evaluated by a competent person. If the excavation is later exposed to wetting influences (rain, flooding), the classification of the soil must be changed accordingly. The ___________ is responsible for the development and maintenance of ICD-10-CM. (v) Material in a sloped, layered system where the layers dip into the excavation on a slope of four horizontal to one vertical (4H:1V) or steeper.

(iv) Soil that meets the unconfined compressive strength or cementation requirements for Type A, but is fissured or subject to vibration; or. Fissured means a soil material that has a tendency to break along definite planes of fracture with little resistance, or a material that exhibits open cracks, such as tension cracks, in an exposed surface. Granular soil cannot be molded when moist and crumbles easily when dry. (B) Samples that dry without cracking are to be broken by hand. This, 10 The is responsible for the development and maintenance of ICD 10 CM a NCHS 11, 9 out of 9 people found this document helpful. An accumulation of numeric or alphanumeric representations or codes for exchanging or, Which of the following is the standard for clinical lab test results under the Meaningful. If the dry soil breaks into clumps which do not break up into small clumps and which can only be broken with difficulty, and there is no visual indication the soil is fissured, the soil may be considered unfissured. Saturated soil means a soil in which the voids are filled with water. Soil composed primarily of coarse-grained sand or gravel is granular material. (ii) Granular cohesionless soils including: angular gravel (similar to crushed rock), silt, silt loam, sandy loam and, in some cases, silty clay loam and sandy clay loam. (v) Drying test. Saturation does not require flow. Granular material that would exhibit cohesive properties when moist will lose those cohesive properties when wet. (This test is based on the thumb penetration test described in American Society for Testing and Materials (ASTM) Standard designation D2488Standard Recommended Practice for Description of Soils (VisualManual Procedure).) Type A soils with an unconfined compressive strength of 1.5 tsf can be readily indented by the thumb; however, they can be penetrated by the thumb only with very great effort. The thumb penetration test can be used to estimate the unconfined compressive strength of cohesive soils. 1-86-NARA-NARA or 1-866-272-6272, Interagency Security Classification Appeals Panel, Fundamental Classification Guidance Review, National Industrial Security Program Policy Advisory Committee, State, Local, Tribal, and Private Sector Policy Advisory Committee, Controlled Unclassified Information Office.
Manual analysis of soil samples is conducted to determine quantitative as well as qualitative properties of soil and to provide more information in order to classify soil properly. The appendix contains definitions, sets forth requirements, and describes acceptable visual and manual tests for use in classifying soils. (b) Definitions. Clinical Data Interchange Standards Consortium, Healthcare Effectiveness Data and Information Set, Diagnostic and Statistical Manual of Mental Disorders. Micaceous seams or weakened planes in rock or shale are considered layered. Cohesive material can be successfully rolled into threads without crumbling. As you have been reviewing her chart, you have found inconsistencies, or minimal information, and you are wanting to know more. Visual analysis is conducted to determine qualitative information regarding the excavation site in general, the soil adjacent to the excavation, the soil forming the sides of the open excavation, and the soil taken as samples from excavated material. LOINC would be found in the UMLS ____________. Saturation, or near saturation, is necessary for the proper use of instruments such as a pocket penetrometer or sheer vane. If they pulverize easily into very small fragments, the material is granular, Occupational Safety & Health Administration, Occupational Safety and Health Administration, Severe Storm and Flood Recovery Assistance, 1926 Subpart P App A - Soil Classification. Stable rock means natural solid mineral matter that can be excavated with vertical sides and remain intact while exposed. The UHDDSs core data elements were incorporated into the ___________ prospective, Which standard is attached to the data element smoking status contained in the Common. Cohesive soils include clayey silt, sandy clay, silty clay, clay and organic clay.
