Exposure may also occur during repair or maintenance activities on contaminated equipment such as: furnacerebuilding, maintenance or repair of air cleaning equipment, structural renovation, welding, etc.
Particulate depositing on hands, gloves, and clothing, can be transferred to the breathing zone and inhaledduring normal hand to face motions such as rubbing of the nose or eyes, sneezing, coughing, etc.
3.2.1 Inhalation
Particulate containing those elements listed in Section 2 can cause irritation to the nose, throat, lungs, andmucous membranes. Inhalation of this particulate may cause metal fume fever (high temperature, metallic taste,nausea, coughing, general weakness, muscle aches, and exhaustion), bronchitis, chills, decreased pulmonaryfunction, and asthma-like symptoms.
Beryllium: The beryllium in this product is not known to cause acute health effects. Inhaling particulatecontaining beryllium may cause a serious, chronic lung disease called Chronic Beryllium Disease (CBD) in someindividuals. See section 3.2.5 Chronic (long-term health effects).
Cobalt: May cause asthmatic attacks due to allergic sensitization of the respiratory tract. May cause asthma andshortness of breath.
Copper: Inhalation of particulate containing metallic copper can cause ulceration and perforation of the nasalseptum.
3.2.2 Ingestion
Ingestion can occur from hand, clothing, food and drink contact with particulate during hand to mouth activitiessuch as eating, drinking, smoking, nail biting, etc.
Beryllium: The health effect of ingestion of beryllium in the form found in this product is unknown.
Cobalt: May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May cause allergic reaction.
Copper: Copper ingestion causes nausea, vomiting, abdominal pain, metallic taste, and diarrhea. Ingestion oflarge doses may cause stomach and intestine ulceration, jaundice, and kidney and liver damage.
3.2.3 Skin
Skin contact with this material may cause, in some sensitive individuals, an allergic dermal response. Skincontact may cause irritation. Symptoms include redness, itching and pain.

3.2.4 Eyes
Exposure may result from direct contact with airborne particulate or contact to the eye with contaminated handsor clothing. Damage can result from irritation or mechanical injury to the eyes by particulate.
Copper: Particulate in the eyes may cause discoloration.
3.2.5 Chronic (long-term health effects)
Beryllium: Inhaling particulate containing beryllium may cause a serious, chronic lung disease called chronicberyllium disease (CBD) in some individuals. Over time lung disease can be fatal. Chronic beryllium disease is ahypersensitivity or allergic condition in which the tissues of the lungs become inflamed. This inflammation,sometimes with accompanying fibrosis (scarring), may restrict the exchange of oxygen between the lungs andthe bloodstream. Medical science suggests that CBD may be related to genetic factors.
Cobalt: Repeated exposure may cause allergic respiratory reaction (asthma). Chronic inhalation of particulatemay lead to restricted pulmonary function and lung fibrosis (scarring). Chronic ingestion may result in heartdamage and/or failure, vomiting, convulsions and thyroid enlargement. Repeated exposure may causesensitization dermatitis.
Copper: Prolonged or repeated exposure to copper can discolor skin and hair and irritate the skin; may causemild dermatitis, runny nose, and irritation of the mucous membranes. Repeated ingestion may damage the liverand kidneys. Repeated Inhalation can cause chronic respiratory disease.
3.2.6 Carcinogenic References
Beryllium: The International Agency for Research on Cancer (IARC) lists beryllium as a Group 1 - KnownHuman Carcinogen. The National Toxicology Program (NTP) lists beryllium as reasonably anticipated to be ahuman carcinogen. The ACGIH lists beryllium as an A1 - Confirmed Human Carcinogen.
IARC lists beryllium as a known human carcinogen (Group1) and notes that the work environment of workersinvolved in refining, machining and producing beryllium metal was associated with an increased risk of lungcancer, "the greater excess was in workers hired before 1950 when exposures to beryllium in the work place wererelatively uncontrolled and much higher than in subsequent decades"; and "the highest risk for lung cancerbeing observed among individuals diagnosed with acute beryllium-induced pneumonitis, who represent a groupthat had the most intense exposure to beryllium." IARC further noted that "Prior to 1950, exposure to berylliumin working environments was usually very high, and concentrations exceeding 1 mg/m3 [1000 micrograms percubic meter] were not unusual." Cobalt: The International Agency for Research on Cancer (IARC) lists cobalt as a Group 2B - PossiblyCarcinogenic to Humans. ACGIH lists elemental cobalt as an A3 - Animal Carcinogen. OSHA lists cobalt as apossible select carcinogen.
3.2.7 Medical Conditions Aggravated by Exposure
Persons with impaired pulmonary function, airway diseases, or conditions such as asthma, emphysema, chronicbronchitis, etc. may incur further impairment if particulate is inhaled. If prior damage or disease to theneurologic (nervous), circulatory, hematologic (blood), or urinary (kidney) systems has occurred, properscreening or examinations should be conducted on individuals who may be exposed to further risk wherehandling and use of this material may cause exposure.
Beryllium: The effects of chronic beryllium disease on the lungs and heart are additive to the effects of otherhealth conditions.

Copper: Persons with pre-existing skin disorders or impaired liver, kidney, or pulmonary function or pre-existingWilson's disease may be more susceptible to the effects of this material.
3.3 POTENTIAL ENVIRONMENTAL EFFECTS
4. FIRST AID MEASURES
4.1 FIRST AID PROCEDURES
INHALATION: Breathing difficulty caused by inhalation of particulate requires immediate removal to fresh air.
If breathing has stopped, perform artificial respiration and obtain medical help.
INGESTION: Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to
an unconscious person.
SKIN: Thoroughly wash skin cuts or wounds to remove all particulate debris from the wound. Seek medical
attention for wounds that cannot be thoroughly cleansed. Treat skin cuts and wounds with standard first aid
practices such as cleansing, disinfecting and covering to prevent wound infection and contamination before
continuing work. Obtain medical help for persistent irritation. Material accidentally implanted or lodged under
the skin must be removed.
EYES: Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids
occasionally. Get medical attention immediately.
4.2 NOTE TO PHYSICIANS
Treatment of Chronic Beryllium Disease: There is no known treatment which will cure chronic beryllium
disease. Prednisone or other corticosteroids are the most specific treatment currently available. They are
directed at suppressing the immunological reaction and can be effective in diminishing signs and symptoms of
chronic beryllium disease. In cases where steroid therapy has had only partial or minimal effectiveness, other
immunosuppressive agents, such as cyclophosphamide, cyclosporine, or methotrexate, have been used. These
latter agents remain investigational. Further, in view of the potential side effects of all the immunosuppressive
medications, including steroids such as prednisone, they should be used only under the direct care of a
physician. In general, these medications should be reserved for cases with significant symptoms and/or
significant loss of lung function. Other symptomatic treatment, such as oxygen, inhaled steroids or
bronchodilators, may be prescribed by some physicians and can be effective in selected cases.
The decision about when and with what medication to treat is a judgment situation for individual physicians.
For the most part, treatment is reserved for those persons with symptoms and measurable loss of lung function.
The value of starting oral steroid treatment, before signs or symptoms are evident, remains a medicallyunresolved issue.
The effects of continued low exposure to beryllium are unknown for individuals who are sensitized to berylliumor who have a diagnosis of chronic beryllium disease. It is generally recommended that persons who aresensitized to beryllium or who have CBD terminate their occupational exposure to beryllium.

This material is non-combustible. Use extinguishing media appropriate tothe surrounding fire.
Do not use water to extinguish fires around operations involving molten metal due to the potential for steam explosions.
Pressure-demand self-contained breathing apparatus must be worn byfirefighters or any other persons potentially exposed to the metal fumesor dust released during or after a fire.
6. ACCIDENTAL RELEASE MEASURES
6.1 STEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED
If this material is a particulate, establish a restricted entry zone based on the severity of the spill. Personsentering the restricted zone must wear adequate respiratory protection and protective clothing appropriate forthe severity of the spill (see Section 8). Cleanup spills with a vacuum system utilizing a high efficiencyparticulate air (HEPA) filtration system followed by wet cleaning methods. Special precautions must be takenwhen changing filters on HEPA vacuum cleaners used to clean up hazardous materials. Be careful to minimizeairborne generation of particulate and avoid contamination of air and water. Depending upon the quantity ofmaterial released into the environment, the incident may be required to be reported to the National ResponseCenter at (800) 424-8802 as well as the State Emergency Response Commission and Local Emergency PlanningCommittee.
7. HANDLING AND STORAGE
7.1 HANDLING
Particulate may enter the body through cuts, abrasions or other wounds on the surface of the skin. Weargloves when handling parts with loose surface particulate or sharp edges.
7.2 STORAGE
8. EXPOSURE CONTROLS, PERSONAL PROTECTION
8.1 VENTILATION AND ENGINEERING CONTROLS
Whenever possible, the use of local exhaust ventilation or other engineering controls is the preferred method ofcontrolling exposure to airborne particulate. Where utilized, exhaust inlets to the ventilation system must bepositioned as close as possible to the source of airborne generation. Avoid disruption of the airflow in the areaof a local exhaust inlet by equipment such as a man-cooling fan. Check ventilation equipment regularly toensure it is functioning properly. Provide training on the use and operation of ventilation to all users. Usequalified professionals to design and install ventilation systems.
Copper Beryllium Casting Alloys
MSDS No. A19
January 1, 2002
8.2 WORK PRACTICES
Develop work practices and procedures that prevent particulate from coming in contact with worker skin, hair,or personal clothing. If work practices and/or procedures are ineffective in controlling airborne exposure orvisual particulate from deposition on skin, hair, or clothing, provide appropriate cleaning/washing facilities.
Procedures should be written that clearly communicate the facility's requirements for protective clothing andpersonal hygiene. These clothing and personal hygiene requirements help keep particulate from being spreadto non-production areas or from being taken home by the worker. Never use compressed air to clean workclothing or other surfaces.
Fabrication processes may leave a residue of particulate on the surface of parts, products or equipment thatcould result in employee exposure during subsequent material handling activities. As necessary, clean looseparticulate from parts between processing steps. As a standard hygiene practice, wash hands before eating orsmoking.
To prevent exposure, remove surface scale or oxidation formed on cast or heat treated products in anadequately ventilated process prior to working the surface.
8.3 WET METHODS
Machining operations are usually performed under a liquid lubricant/coolant flood which assists in reducingairborne particulate. However, the cycling through of machine coolant containing finely divided particulate insuspension can result in the concentration building to a point where the particulate may become airborneduring use. Certain processes such as sanding and grinding may require complete hooded containment andlocal exhaust ventilation. Prevent coolant from splashing onto floor areas, external structures or operators'clothing. Utilize a coolant filtering system to remove particulate from the coolant.
8.4 RESPIRATORY PROTECTION
When airborne exposures exceed or have the potential to exceed the occupational limits shown in Section 8.13,approved respirators must be used as specified by an Industrial Hygienist or other qualified professional.
Respirator users must be medically evaluated to determine if they are physically capable of wearing a respirator.
Quantitative and/or qualitative fit testing and respirator training must be satisfactorily completed by allpersonnel prior to respirator use. Users of tight fitting respirators must be clean shaven on those areas of theface where the respirator seal contacts the face. Exposure to unknown concentrations of particulate requiresthe wearing of a pressure-demand airline respirator or pressure-demand self-contained breathing apparatus(SCBA). Use pressure-demand airline respirators when performing jobs with high potential exposures such aschanging filters in a baghouse air cleaning device.
8.5 OTHER PROTECTIVE EQUIPMENT
Protective overgarments or work clothing must be worn by persons who may become contaminated withparticulate during activities such as machining, furnace rebuilding, air cleaning equipment filter changes,maintenance, furnace tending, etc. Contaminated work clothing and overgarments must be managed in acontrolled manner to prevent secondary exposure to workers of third parties, to prevent the spread ofparticulate to other areas, and to prevent particulate from being taken home by workers.
8.6 PROTECTIVE GLOVES
Wear gloves to prevent contact with particulate or solutions. Wear gloves to prevent metal cuts and skinabrasions during handling.
Copper Beryllium Casting Alloys
MSDS No. A19
January 1, 2002
8.7 EYE PROTECTION
Wear safety glasses, goggles, face shield, or welder's helmet when risk of eye injury is present, particularlyduring melting, casting, machining, grinding, welding, powder handling, etc.
8.8 HOUSEKEEPING
Use vacuum and wet cleaning methods for particulate removal from surfaces. Be certain to de-energize electricalsystems, as necessary, before beginning wet cleaning. Use vacuum cleaners with high efficiency particulate air(HEPA). Do not use compressed air, brooms, or conventional vacuum cleaners to remove particulate fromsurfaces as this activity can result in elevated exposures to airborne particulate. Follow the manufacturer'sinstructions when performing maintenance on HEPA filtered vacuums used to clean hazardous materials.
8.9 MAINTENANCE
During repair or maintenance activities the potential exists for exposures to particulate in excess of theoccupational standards. Under these circumstances, protecting workers can require the use of specific workpractices or procedures involving the combined use of ventilation, wet and vacuum cleaning methods,respiratory protection, decontamination, special protective clothing, and when necessary, restricted work zones.
8.10 WELDING
In accordance with OSHA regulation 29 CFR 1910.252 welding of materials containing beryllium is regulated asfollows: Welding or cutting indoors, outdoors, or in confined spaces involving beryllium containing base orfiller metals shall be done using local exhaust ventilation and pressure-demand airline respirators unlessatmospheric tests under the most adverse conditions have established that the workers' exposure is within theacceptable concentrations defined by 29 CFR 1910.1000. In all cases, workers in the immediate vicinity of thewelding or cutting operations shall be protected as necessary by local exhaust ventilation or airline respirators.
8.11 EXPOSURE CHARACTERIZATION
Determine exposure to airborne particulate by air sampling in the employee breathing zone, work area, anddepartment. Utilize an Industrial Hygienist or other qualified professional to specify the frequency and type ofair sampling. Develop and utilize a sampling strategy which identifies the extent of exposure variation andprovides statistical confidence in the results. Conduct an exposure risk assessment of processes to determine ifconditions or situations exist which dictate the need for additional controls or improved work practices. Makeair sample results available to employees.
8.12 MEDICAL SURVEILLANCE
Beryllium: Medical surveillance for beryllium health effects includes (1) skin examination, (2) respiratory history,(3) examination of the lungs, (4) lung function tests (FVC and FEV1), and (5) periodic chest x-ray. In addition, aspecialized, specific, immunological blood test, the beryllium blood lymphocyte proliferation test (BLPT), isavailable to assist in the diagnosis of beryllium related reactions. Individuals who have an abnormal BLPT arenormally referred to a lung specialist for additional specific tests to determine if chronic beryllium disease ispresent. Note: Substantial inter- and intra-laboratory disagreement exists among the laboratories that conductthis test. The BLPT does not at this time meet the criteria for a screening test. Despite its limitations however,the BLPT remains a useful disease surveillance tool.

8.13 RISK FACTORS
Specific genetic factors have been identified and have been shown to increase an individual's susceptibility toCBD. Medical testing is available to detect genetic factors in individuals.
8.14 OCCUPATIONAL EXPOSURE LIMITS
*ALL CONCENTRATIONS ARE IN MILLIGRAMS PER CUBIC METER OF AIR (at the concentrations noted above, these constituents may not be visible to the human eye) A leading scientific body recommending occupational standards is the American Conference of GovernmentalIndustrial Hygienists (ACGIH). The ACGIH recommends standards for all listed substances. The ACGIHdefines a threshold limit value (standard) as follows: "Threshold Limit Values refer to airborne concentrationsof substances and represent conditions under which it is believed that nearly all workers may be repeatedlyexposed day after day without adverse health effects. Because of wide variation in individual susceptibility,however, a small percentage of workers may experience discomfort from some substances at concentrations ator below the threshold limit; a smaller percentage may be affected more seriously by aggravation of a pre-existing condition or by development of an occupational illness." "Individuals may also be hypersusceptible orotherwise unusually responsive to some industrial chemicals because of genetic factors, age, personal habits(smoking, alcohol, or other drugs), medication, or previous exposures. Such workers may not be adequatelyprotected from adverse health effects from certain chemicals at concentrations at or below the threshold limits."

AMBIENT AIR EMISSIONS: Foundries melting alloys containing beryllium are subject to the National
Emission Standard for Beryllium as promulgated by EPA (40 CFR 61, Subpart C). Facilities machining alloys
containing greater than 5% beryllium also are subject to the National Emission Standard for beryllium. The
National Emission Standard for beryllium is 0.01 micrograms per cubic meter (30 day average) in ambient air for
those production facilities which have been qualified to be regulated through ambient air monitoring. Other
facilities must meet a 10 gram per 24-hour total site emission limit. Most process air emission sources will
require an air permit from a local and/or state air pollution control agency. The use of air cleaning equipment is
recommended to achieve the permissible emission. Provide tempered makeup air to prevent excessive negative
pressure in a building. Direct recycling of filtered process exhaust air is not recommended. Locate plant
exhausts so as not to re-enter the plant through makeup air or other inlets. Regular maintenance and inspection
