4.1 Use of this practice will improve management and control of metal removal fluids. The proper management and use will reduce dermal and other occupational hazards associated with these fluids.

4.1.1 Guide E2148 covers information on how to use documents related to health and safety of metalworking and metal removal fluids, including this document. Documents referenced in Guide E2148 are grouped as applicable to producers, to users, or to all.

4.1.2 Practices E2693 and E2889 augment the information provided in this practice by providing information on prevention of dermatitis and on approaches to reducing exposures to different types of metal removal fluid related aerosols.

1.1 This practice sets forth guidelines for the selection and safe use of metal removal fluids, additives, and antimicrobials. This includes product selection, storage, dispensing, and maintenance.

1.2 Water-miscible metal removal fluids are typically used at high dilution, and dilution rates vary widely. Additionally, there is potential for exposure to undiluted metal removal fluid as manufactured, as well as metal removal fluid additives and antimicrobials.

1.3 Straight oils generally consist of a severely solvent-refined or hydro-treated petroleum oil, a synthetic oil, or other oils of animal or vegetable origin, including oils that are modified for performance characteristics (for example, esterified rapeseed oil, and so forth). Straight oils are not intended to be diluted with water prior to use. Additives are often included in straight oil formulations.

1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
