ASTM E2875/E2875M-12 (R2021) pdf free download.Standard Guide for Personal Protective Equipment for the Handling of Flat Glass.
1.1 This guide covers the minimum requirements for proper personal protective equipment (PPE) for the safe handling of flat glass.
1.2 Purpose—When engineering, administrative, and work practice controls are not feasible, the remaining hazard must he controlled with personal protective equipment (PPE). This guide will provide direction on what PPE should be utilized. Following this guidance will help to minimize the possibility or severity of injuries, or both, to personnel while working with or in the vicinity of flat glass.
1.3 Nothing in this guide shall be interpreted as requiring any action that violates any statute or requirement of any federal, state, or other regulatory agency.
1.4 This guide may be used by employers and employees. The required PPE shall be evaluated on a regular basis to determine suitability.
1 .5 Units—The values stated in either SI units or inch- pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall he used independently of the other. Combining values from the two systems may result in nonconformance with the standard.
4. Significance and Use
4.1 The goal of this guide is to aid in the selection of PPE for the handling of glass that will best protect the affected employee from the remaining hazards identified in the local hazard assessment process.
4.2 This guide assumes that a proper hazard assessment has been conducted, the hazards have been mitigated to the greatest extent possible by non-PPE means (engineering, administrative, or work practice controls), and a hazard still exists that can oniy feasibly be controlled by the use of PPE.
5. Level of Cut Protection
5.1 Cut-resistant clothing (gloves and body protection) is evaluated primarily by two standards: Test Method F1790 and
EN 388.
5.2 In Test Method F1790, cut-resistant material is evaluated. The process of evaluation or cut protection performance test (CPPT) involves the amount of pressure or gram weight applied to a razor blade while moving the blade over the fabric without cutting through for at least 20 mm 10.8 in.1. The higher the load in gram weight applied to the blade without cut- through for the prescribed distance of travel, the better the cut resistance of the fabric. This result is termed the cut or rating force of the fabric. Test Method F1790 cut or rating force levels are listed in Table 1.
5.3 In EN 388 or the Couptest, cut-resistant material is evaluated. The process of the evaluation involves a constant weight on a circular blade that is moved back and forth across a tesL specimen by the test machine. The machine (Couptest) also rotates the blade against the direction that it is being moved, which intensities the slicing action. The test indicates how many repetitive cuts on the same position are needed to cut through. The result of the test is termed the cut index, which informs of how much better the sample resists cut as compared to a reference cotton fabric. A performance level for the material is ranked from 0 to 5. The higher the number of cycles needed to cut through the material, the greater the cut resistance of the fabric. The EN 388 cut index levels are listed in Table 2.ASTM E2875/E2875M pdf download.
