Respiratory Health Hazards Associated with MetalRemoval Fluids5.1 General:5.1.1 Metal removal fluids (MRF) can cause adverse healtheffects through skin contact with contaminated materials,spray, or mist and through inhalation from

35、 breathing MWFmist or aerosol.5.1.2 Skin and airborne exposures to MRF have beenimplicated in health problems including irritation of the skin,lungs, eyes, nose and throat. Conditions such as dermatitis,acne, asthma, hypersensitivity pneumonitis, irritation of theupper respiratory tract, and a varie

36、ty of cancers have beenassociated with exposure to MRF (NIOSH 1998a). The sever-ity of health problems is dependent on a variety of factors suchas the kind of fluid, the degree and type of contamination, andthe level and duration of the exposure.5.2 Skin Disorders:5.2.1 Skin contact occurs when the

37、worker dips his/herhands into the fluid or handles parts, tools, and equipmentcovered with fluid without the use of personal protectiveequipment, such as gloves and aprons. Skin contact may alsoresult from fluid splashing onto the employee from the machineif guarding is absent or inadequate. For fur

38、ther informationrefer to E2693 Practice for Prevention of Dermatitis in the WetMetal Removal Fluid Environment.5.3 Respiratory Diseases:5.3.1 Inhalation of MRF mist or aerosol may cause irritationof the lungs, throat, and nose. In general, respiratory irritationinvolves some type of chemical interac

39、tion between the MRFand the human respiratory system. Irritation may affect one ormore the following areas: nose, throat (pharynx, larynx), thevarious conducting airways or tubes of the lungs (trachea,bronchi, bronchioles), and the lung air sacks (alveoli) wherethe air passes from the lungs into the

40、 body. Exposure to MRFmist or aerosol may also aggravate the effects of existing lungdisease.5.3.2 Some of the symptoms reported include sore throat,red, watery, itchy eyes, runny nose, nosebleeds, cough,wheezing, increased phlegm production, shortness of breath,and other cold like symptoms. These s

41、ymptoms may indicate avariety of respiratory conditions, including acute airwayirritation, asthma (reversible airway obstruction), chronicbronchitis, chronically impaired lung function, and hypersen-sitivity pneumonitis (HP). When symptoms of respiratoryirritation occur, in many cases it is unclear

42、whether the diseasewas caused by specific fluid components, contamination of thein-use fluid, products of microbial growth or degradation, or acombination of factors.5.3.3 Exposure to MRF has been associated with asthma. Inasthma, airways of the lung become inflamed, causing areduction of the flow o

43、f air into and out of the lungs. During anasthmatic attack, the airways become swollen, go into spasmsand fill with mucous, reducing airflow and producing shortnessof breath and a wheezing sound. A variety of components,additives, and contaminants of MRF can induce new-onsetasthma, aggravate pre-exi

44、sting asthma, and irritate the airwaysof non-asthmatic employees.5.3.4 Chronic bronchitis is a condition involving inflamma-tion of the main airways of the lungs that occurs over a longperiod of time. Chronic bronchitis is characterized by a chroniccough and by coughing up phlegm. The phlegm can int

45、erferewith air passage into and out of the lungs. This condition mayalso cause accelerated decline in lung function, which canultimately result in heart and lung function damage.5.3.5 Hypersensitivity pneumonitis (HP) is a serious lungdisease. Recent outbreaks of HP have been associated withexposure

46、 to aerosols of synthetic, semi-synthetic, and solubleoil MRF. In particular, contaminants and additives in MRFhave been associated with outbreaks of HP (NIOSH 1998a). Inthe short term, HP is characterized by coughing, shortness ofbreath, and flu-like symptoms (fevers, chills, muscle aches, andfatig

47、ue). The chronic phase (following repeated exposures) ischaracterized by lung scarring associated with permanent lungdisease.5.3.6 Other factors, such as smoking, increase the possibil-ity of respiratory diseases. Cigarette smoke may worsen therespiratory effects of MRF aerosols for all employees.5.

48、3.7 Respiratory effects have been observed among work-ers with exposures below 1.0 mg/M3to diverse fluids,12withwater reduced fluids generally appearing more potent. Poorlycontrolled fluids have generally been more likely to be asso-ciated with adverse effects.5.4 Cancer:5.4.1 A number of studies ha

49、ve found an association be-tween working with MRF and a variety of cancers, includingcancer of the rectum, pancreas, larynx, skin, scrotum, andbladder (NIOSH 1998a). No authoritative review of studies ofworkers exposed to MRF has been conducted since 1999,although additional data have been published. Studies of MRFand cancer reflect the health experiences of workers exposeddecades earlier. This is because the effects of cancers associ-ated with MRF may not become evident until many years afterthe exposure. Airborne concentrations of MWF were known tobe much higher in the
