The most common origins areirritant or allergic responses to a chemical or physical agent.Signs and symptoms that typify the initial onset of dermatitisinclude: erythema (redness); edema (swelling); pruritis (itch-ing); and, vesiculation (pimple-like eru

18、ptions). In more severecases, fissures (deep cracks) and ulcers (open sores) maydevelop. The condition is usually reversible when exposure tothe causative agent ceases.

Documentsreferenced in Guide E 2148 are grouped as applicable toproducers, to users, or to all.5. Routes of Metal Removal Fluid Exposure and Effectsof Overexposure5.1 Routes of exposure to meta

29、l removal fluids include eyecontact, inhalation, ingestion, and dermal contact. Exposuremay be through contact with the fluid or by contact withairborne fluid mists, vapor, splashing, or residual fluid onmachinery, parts, or clothing.5.2 Eye contact may cause mild to severe irritation, depend-ing on

30、 the concentration and specific characteristics (forexample, alkalinity) of the product.5.2.1 Prevent eye contact. Ensure that splash guarding isfunctional or wear eye protection appropriate for the level ofsplashing or spraying encountered, such as safety glasses withside shields or goggles. See 29

31、 CFR 1910.133.5.3 Inhalation may cause respiratory irritation or other typesof respiratory effects (see 5.3.4).5.3.1 Reduce exposure to mists and vapors. Permissibleexposure levels (OSHA) of the fluid and component ingredi-ents shall not be exceeded. Engineering controls, such asmachine enclosures a

32、nd exhaust ventilation or substitution withlow-mist products are preferred methods to control exposure.5.3.2 Test Method D 7049 may be used for the determina-tion of both particulate total matter and extractable mass metalremoval fluid aerosol concentrations in a range of 0.05 to 5mg/m3in workplace

33、atmospheres.5.3.3 See Practice E 1972 for guidelines for minimizingeffects of aerosols in the wet metal removal environment.5.3.4 For additional information, see Criteria for a Recom-mended Standard Occupational Exposure to Metal WorkingFluids.55.4 Ingestion may cause gastrointestinal disturbances.5

34、.5 Prolonged or repeated dermal contact may cause dry andcracked skin, rash, redness, burning, or itching.

Some metal removal fluids andadditives may sensitize the skin of affected employees, whichcan result in a response to very low levels of exposure.6. Fluid Product Selection6.1 Proper product selection is fundamentally criti

36、cal toreducing or eliminating respiratory conditions and occupa-tional dermatitis associated with exposure to metal removalfluids. The metal removal fluids should perform as intendedwhile providing the safest working conditions. The selection ofa metal removal fluid for each different operation must

37、 con-sider the inherent limitations of the product. Water-misciblefluids not properly selected are likely to be used at higherconcentrations than other products more appropriate to theoperation.6.1.1 Consult “Management of the Metal Removal Environ-ment” and “Metalworking Fluids Evaluation Guide”6fo

38、rfurther information on selecting the proper fluid for theapplication. In addition, your fluid supplier, chemical manager,or corporate subject matter expert should be able to provideinformation on the proper selection of the appropriate fluid andrecommended concentration for use.6.2 Potential health

39、 hazards can be reduced by careful fluidselection and substitution. See Guide E 1302 and consult“Metalworking Fluids: Safety and Health Best PracticesManual”7for further information.6.3 The metal removal fluid manufacturers material safetydata sheet (MSDS) and toxicological data must be completeand

40、must provide all applicable information on metal removalfluids, ingredients, and additives. This data shall be reviewed inorder to evaluate potential hazards and establish appropriatecontrol procedures.6.4 The metal removal fluid manufacturer must provide allapplicable health, safety, and toxicologi

41、cal data on additives,including rust inhibitors, product stabilizers, and antimicrobi-als of all types, odorants, and dyes. These data shall bereviewed for their impact on the metal removal fluid mixture towhich they are added. Additives shall only be used with theagreement of the metalworking fluid

42、 manufacturer and theappropriate health and safety personnel in the plant.6.5 As supplied, antimicrobials and other additives fortankside addition may present greater health and safety risksthan the metal removal fluid. Further, additives and antimicro-bials are less likely to be handled automatical

43、ly, or with specialdelivery equipment, than metal removal fluid concentrate sogreater care and attention are required to reduce risks ofexposure.6.5.1 To avoid recognized health and safety hazards, metalremoval fluid formulations shall not contain nitrites or nitro-sating agents, petroleum oils that

44、 are not severely refined,chlorinated paraffins that have been identified as carcinogens,and other constituents listed in applicable purchase specifica-tions.6.6 All applicable disposal criteria must be met. If there isan on-site wastewater treatment plant, consult with the operatorat the time of fl

45、uid selection.7. Water Quality and Treatment7.1 Water constitutes more than 90 % of the diluted watermiscible metal removal fluid mixture. Water shall be evaluatedfor hardness, alkalinity, high conductivity, turbidity, corrosiv-ity, biological contaminants, and other factors that may lead toincrease

46、d use of metal removal fluid concentrate, additives, orantimicrobials, or a combination thereof. Good water quality isfundamental to proper metal removal fluid use, will helpreduce use of additives and antimicrobials, and lengthen fluidlife. Consult your metal removal fluid supplier, chemicalmanager

47、, and corporate subject matter expert.7.2 Where suitable water is not available, water treatmentshall be designed to produce enough water of sufficient qualityfor metal removal fluid use. Treated water shall be readilyavailable from holding tanks large enough to meet anticipateddaily requirements. T

48、reated water quality, including biologicalcontaminants, must be monitored. Tests performed depend onthe type of water treatment used. Guidance on water qualityand water treatment may be obtained from the metal removalfluid manufacturer.8. Receipt and Handling of Fluid and Additives8.1 Before the flu

49、id is handled, the user shall have anaccurate and current material safety data sheet as required bythe OSHA Hazard Communication Standard. See 29 CFR1910.1200.8.2 Precautions shall be taken to ensure the fluid is, withoutmodification, the fluid represented in the material safety datasheet.8.3 Users should be informed prior to modifications in fluidformulation so that they may assess potential effects on healthand safety and productivity. Seemingly insignificant changes influid composition may result in adverse interaction with otheradditives or may produce unforeseen chan
