Significance and Use4.1 Application of this guide will provide information onthe acute toxicity of water-miscible metalworking fluids andwill assist the user in evaluating the potential
16、health hazards ofthe fluid and developing appropriate work practices. A water-miscible metalworking fluid is a concentrate designed to bediluted in water for use.4.2 Water-miscible metalworking fluids are complex chemi-cal mixtures. The United States Occupational Safety andHealth Administration (OSH
17、A) Hazard Communication Stan-dard (see A1.8) outlines procedures for the hazard determina-tion of mixtures and states that if a mixture has not been testedas a whole, then the mixture shall be assumed to present thesame hazards as do the components that comprise 1 % (byweight or volume) or greater o
18、f the mixture, except that themixture shall be assumed to present a carcinogenic hazard if itcontains a component in concentrations of 0.1 % or greater,which is considered to be a carcinogen (as defined in OSHAStandard 29 CFR 1910.1200). The determination of when totest a mixture as a whole and whic
19、h toxicity tests areappropriate for the product must be made by a health profes-sional qualified in evaluating toxicological data.4.3 Acute toxicology testing of water-miscible metalwork-ing fluids consists of several individual tests including acuteoral, dermal, or inhalation toxicity, eye irritati
20、on, skin irritationor corrosion, or both, skin sensitization, and sensory irritation.Certain protocols for acute oral, dermal, and inhalation toxicitytests are limit tests; further multi-dose testing (for example,Test Method E1103) should take place if mortality is noted onany of these tests. The re
21、ferenced protocols specify the speciesand number of animals required. Selection of tests conductedshould be designed to minimize the number of animals used.4.3.1 Acute Oral ToxicityAcute oral toxicity tests (seeA1.1) provide information on health hazards likely to arisefrom short-term exposure by th
22、e oral route. Results of this typeof test are used to develop warning statements on labels as maybe required by OSHA Hazard Communication Standard 29CFR 1910.1200 (see A1.8) or Federal Hazardous SubstancesAct (see A1.10). These are also used to establish a dosageregimen for subchronic and other test
23、ing. Endpoint: mortality.4.3.2 Acute Dermal ToxicityAcute dermal toxicity tests(see A1.2) provide information on health hazards likely to arisefrom short-term exposure by the dermal route and may provideinitial information on dermal absorption and the mode of toxicaction of a substance. In addition,
24、 some measure of irritationcaused by the fluid may be obtained by observing local tissuedamage at the sight of application. Endpoint: mortality.4.3.3 Acute Inhalation ToxicityAcute inhalation toxicitytests give an indication of relative toxicity (see A1.3). Theresults provide an indication of the po
25、tential of the fluid tocause death and other adverse health effects when inhaled fora specified time period. Endpoint: mortality.4.3.4 Eye IrritationEye irritation tests provide an indica-tion of the potential of the fluid to cause eye irritation ordamage upon direct contact (see A1.4).An irritant i
26、s defined asa chemical that is not corrosive, but causes a reversibleinflammatory effect on living tissue by chemical action at thesite of contact. Endpoint: degree of irritation.4.3.5 Skin Irritation or CorrosionSkin irritation or corro-sion tests indicate the potential of the fluid to produce irri
27、tationor damage to skin (see A1.5). A corrosive chemical is one thatcauses visible destruction of, or irreversible alterations in,living tissue by chemical action at the site of contact. Endpoint:irritation or corrosion.4.3.6 Skin SensitizationA chemical sensitizer is a materialthat causes a substan
28、tial proportion of exposed people oranimals to develop an allergic reaction in normal tissue afterrepeated exposure to the chemical. A number of methods areavailable for measuring skin sensitization, however, there aredifferences in opinion on the most appropriate method. Theseare due to variations
29、in compound administration and degree ofreaction to a sensitizing substance. Refer to the Code ofFederal Regulations (CFR) for the various protocols (seeA1.6). Additionally, toxicology testing contract labs may havestandard procedures for conducting these assays. Endpoint:sensitization.4.3.7 Sensory
30、 IrritationUpon exposure to a sensoryirritant, humans experience discomfort or a burning sensationof the eyes, nose, and throat, and may also cough. Test MethodE981 (see A1.2.5) provides a means to evaluate the sensoryirritant potential of airborne chemicals and mixtures, as well asa means to assess
31、 the comparative irritancy of compounds andformulations. However, this test method cannot be used toevaluate the relative obnoxiousness of odors. End point: upperrespiratory tract irritation.4.4 A number of federal guidelines can be used to establishgeneral procedures for testing acute toxicity of m
32、etalworkingfluids. Several references are cited in Annex A1. Regardless ofthe method used, Good Laboratory Practices, as outlined by theUnited States Environmental Protection Agency (EPA 40 CFR792) (see A1.9) must be followed. The OSHA Hazard Com-munication Standard (see A1.8) outlines the responsib
33、ilities ofchemical manufacturers, importers, and employers in thedetermination of chemical hazards and communication ofinformation on those hazards.4.5 The methods referenced in this guide, or appropriatealternate methods such as those suggested by the Organizationfor Economic Cooperation and Develo
34、pment (OECD), areacceptable for testing the acute toxicity of water-misciblemetalworking fluids. For each test outlined in Annex A1.1 A1.5, a table is included that highlights the similarities anddifferences between the test protocols.5.
