1.1 This practice sets forth guidelines for the safe use of water-miscible metalworking fluids. This includes product selection, storage, dispensing, and maintenance. 1.2 Although water-miscible metalworking fluids are typically used at high dilution, dilution rates vary widely. Additionally, there is potential for exposure to metalworking fluid as manufactured and exposure to concentrated and diluted metalworking fluid additives and biocides. 1.3 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 and health practices and determine the applicability of regulatory limitations prior to use.
