Cleavage Fragments

Term: Cleavage FragmentsDefinition: Particles that result from the breaking of a mineral along its planes of weakness, which can resemble asbestos fibers in shape but differ in origin and properties.Phonetic Pronunciation: (KLEE-vij FRAJ-munts)Origin: The term "cleavage" comes from the Old French "clever," meaning to split or divide, and "fragments" from the Latin "fragmentum," meaning a broken piece. In mineralogy, these terms are used to describe how minerals break along their natural planes of weakness.Significance in Asbestos Context: Cleavage fragments are significant because they can be confused with asbestos fibers due to their similar appearance. However, they do not pose the same health risks as asbestos because they lack the fibrous structure and durability of asbestos. Accurate identification of cleavage fragments versus asbestos fibers is crucial for proper risk assessment and regulatory compliance.Example Sentence: During the asbestos survey, the consultant determined that the hazardous material identified in the building was actually cleavage fragments from a non-asbestos mineral, reducing the need for extensive remediation.Related Terms: Asbestos fibers, mineralogy, amphibole, chrysotile, non-asbestiform.Notes: - Cleavage fragments can be misidentified as asbestos under a microscope without proper analytical techniques. - Not all minerals that produce cleavage fragments are hazardous. - Regulatory standards often distinguish between asbestos fibers and cleavage fragments for health and safety assessments.
