1. Scope
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 be 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 ofinjuries, 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 be used independently ofthe other. Combining values from the two systems may result in noncon- formance with the standard. 1.6 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 appro- priate safety, health, and environmental practices and deter- mine the applicability ofregulatory limitations prior to use. 1.7 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Terminology
3.1 Definitions—For additional definitions and terms relat- ing to this guide, please refer to Terminologies C162, E1542, and F1494. 3.2 Definitions ofTerms Specific to This Standard: 3.2.1 flat glass, n—general term covering glass in its an- nealed state, such as sheet glass, lite of glass, float glass, various forms of rolled glass, and raw products derived from glass. 3.2.1.1 Discussion—This definition is not intended to apply to heat-tempered or laminated glass products. With heat- tempered or laminated glass products, defer to your local risk assessment. 3.2.2 lite, n—another term for a pane or piece of glass. Sometimes spelled “light” in the industry literature, but spelled “lite” in this text to avoid confusion with light as in “visible light.”
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. N OTE 1—The two standards are not interchangeable and need to be distinguished as to their unique testing outcomes. N OTE 2—Cut ratings are a starting point for selecting the proper PPE. In general terms, a higher cut level means better cut protection, but that is not always the case. There will be some tasks where a “thicker” material with a lower level of cut protection may actually protect better than a “thinner” material with a higher level of cut protection. Introducing a change (process, job, equipment, etc.) or new PPE for a task should include the proper assessment and trials to ensure the garment does indeed get the desired result. 5.2 In Test Method F1790, cut-resistant material is evalu- ated. 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 [0.8 in.]. 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 ofthe 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 test specimen by the test machine. The machine (Couptest) also rotates the blade against the direction that it is being moved, which intensifies 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.
