General Information
Show this safety data sheet to the doctor on duty.
If dust, fumes or mist inhaled, remove patient to fresh air, allow to rest and keep warm. Breathing difficulty caused by inhalation of particulate requires immediate removal to fresh air. If breathing has stopped, perform artificial respiration and obtain medical help Beryllium: The beryllium in this product is not known to cause acute health effects. Inhaling particulate containing beryllium may cause a serious, chronic lung disease called Chronic Beryllium Disease (CBD) in some individuals. Cobalt: May cause asthmatic attacks due to allergic sensitization of the respiratory tract. May cause asthma and shortness of breath. Copper: Inhalation of particulate containing metallic copper can cause ulceration and perforation of the nasal septum. Skin contact
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.
Beryllium: Particulate that becomes lodged under the skin has the potential to induce
sensitization and skin lesions.
Cobalt: Prolonged and/or repeated contact may cause dermatitis.
Copper: Particulate may cause a greenish-black skin discoloration.
Eye contact
Avoid getting finely divided particles in the eyes. Immediately flush eyes with plenty of water for
at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention
Copper: Particulate in the eyes may cause discoloration.
Alloys in massive form are not hazardous, but should be kept out of the mouth. Finely divided
particles may be easily ingested along with food, drink or smoking. If large quantities ingested,
seek medical advice. Induce vomiting immediately as directed by medical personnel. Never give
anything by mouth to an unconscious person.

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 of large doses may cause stomach and intestine ulceration, jaundice, and kidney and liver damage. Chronic (long-term health effects)
Beryllium: Inhaling particulate containing beryllium may cause a serious, chronic lung disease
called chronic beryllium disease (CBD) in some individuals. Over time, lung disease can be fatal.
Chronic beryllium disease is a hypersensitivity 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 and the bloodstream. Medical science
suggests that CBD may be related to genetic factors.
Cobalt: Repeated exposure may cause allergic respiratory reaction (asthma). Chronic inhalation
of particulate may lead to restricted pulmonary function and lung fibrosis (scarring). Chronic
ingestion may result in heart damage and/or failure, vomiting, convulsions and thyroid
enlargement. Repeated exposure may cause sensitization dermatitis.
Copper: Prolonged or repeated exposure to copper can discolor skin and hair and irritate the
skin; may cause mild dermatitis, runny nose, and irritation of the mucous membranes. Repeated
ingestion may damage the liver and kidneys. Repeated Inhalation can cause chronic respiratory
Carcinogenic References
Beryllium: The International Agency for Research on Cancer (IARC) lists beryllium as a Group 1 –
Known Human Carcinogen. The National Toxicology Program (NTP) lists beryllium as known to be
human carcinogens.
IARC lists beryllium as a known human carcinogen (Group 1) and notes that the work environment
of workers involved in refining, machining and producing beryllium metal was associated with an
increased risk of lung cancer, “the greater excess was in workers hired before 1950 when
exposures to beryllium in the work place were relatively uncontrolled and much higher than in
subsequent decades”; and “the highest risk for lung cancer being observed among individuals
diagnosed with acute beryllium-induced pneumonitis, who represent a group that had the most
intense exposure to beryllium.” IARC further noted that “Prior to 1950, exposure to beryllium in
working environments was usually very high, and concentrations exceeding 1 mg/m3 [1000
micrograms per cubic meter] were not unusual.”
Cobalt: The International Agency for Research on Cancer (IARC) lists cobalt as a Group 2B –
Possibly Carcinogenic to Humans. OSHA lists cobalt as a possible select carcinogen.
Medical Conditions Aggravated by Exposure
Persons with impaired pulmonary function, airway diseases, or conditions such as asthma,
emphysema, chronic bronchitis, etc. may incur further impairment if particulate is inhaled. If
prior damage or disease to the neurologic (nervous), circulatory, hematologic (blood), or urinary
(kidney) systems has occurred, proper screening or examinations should be conducted on
individuals who may be exposed to further risk where handling 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 other health conditions.
Copper: Persons with pre-existing skin disorders or impaired liver, kidney, or pulmonary function
or pre-existing Wilson's disease may be more susceptible to the effects of this material.

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 medically unresolved issue. The effects of continued low exposure to beryllium are
unknown for individuals who are sensitized to beryllium or who have a diagnosis of chronic
beryllium disease. It is generally recommended that persons who are sensitized to beryllium or
who have CBD terminate their occupational exposure to beryllium.
Non-combustible as a solid. No ignition as layer of sub 44 micron particles of copper. Not applicable to solids. No ignition as cloud of sub 44 micron particles of nominal copper. This material is non-combustible. Use extinguishing media appropriate to the 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 by firefighters or any other persons potentially exposed to the metal fumes or dust released during or after a fire.
If this material is a particulate, establish a restricted entry zone based on the severity of the spill. Persons entering the restricted zone must wear adequate respiratory protection and protective clothing appropriate for the severity of the spill (see Section 8). Cleanup spills with a vacuum system utilizing a high efficiency particulate air (HEPA) filtration system followed by wet cleaning methods. Special precautions must be taken when changing filters on HEPA vacuum cleaners used to clean up hazardous materials. Be careful to minimize airborne generation of particulate and avoid contamination of air and water. UDDEHOLM TOOLING SAFETY DATA SHEET

Recommendations for safe handling
No special precautions necessary for alloys in massive form other than normal physical handling
techniques. Extraction should be used when working with particulate material (dust, fumes,
mist). Avoid prolonged inhalation of dust. Wear gloves to avoid contact with skin (see Section 8).
Store in a dry area.
*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 Governmental Industrial Hygienists (ACGIH). The ACGIH recommends standards for all listed substances. The ACGIH defines a threshold limit value (standard) as follows: “Threshold Limit Values refer to airborne concentrations of substances and represent conditions under which it is believed that nearly all workers may be repeatedly exposed 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 at or 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 or otherwise 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 adequately protected from adverse health effects from certain chemicals at concentrations at or below the threshold limits.” ACGIH = American Conference of Governmental Industrial Hygienists OSHA = Occupational Safety and Health Administration PEL = Eight-Hour Average Permissible Exposure Limit (OSHA) CEILING = Not To Be Exceeded Except for Peak Limit (OSHA) PEAK = 30-Minute Maximum Duration Concentration Above Ceiling Limit (OSHA) TLV = Eight-Hour Average Threshold Limit Value (ACGIH) TLV-STEL = 15-Minute Short Term Exposure Limit (ACGIH) CAS = Chemical Abstract Service NIOSH = National Institute for Occupational Safety and Health RTECS = Registry of Toxic Effects of Chemical Substances The manufacture recommends following good industrial hygiene practice which includes reducing airborne exposures to the lowest feasible level for all constituents in this product. Control of Exposure
8.2.1 Respiratory protection
Extraction should be used when working with particulate material (dust, fumes, mist). In case of prolonged or frequent exposure to particulates, wear particle filter mask. When airborne exposures exceed or have the potential to exceed the occupational limits shown in Section 8.1, approved respirators must be used as specified by an Industrial Hygienist or other UDDEHOLM TOOLING SAFETY DATA SHEET

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 all personnel prior to respirator use. Users of tight fitting respirators must be clean shaven on those areas of the face where the respirator seal contacts the face. Exposure to unknown concentrations of particulate requires the 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 as changing filters in a baghouse air cleaning device. 8.2.2 Skin protection
Wear hand protection, eg leather gloves when handling alloys with sharp edges to avoid cuts. Always wear disposable nitrile or vinyl gloves when handling particulate material to avoid skin contact. Where necessary wear the disposable gloves under work gloves to protect against both types of hazard. 8.2.3 Eye protection
Always wear eye protection when handling dusts and other particulates, eg safety glasses with side protection, safety goggles or visor. Wear safety glasses, goggles, face shield, or welder’s helmet when risk of eye injury is present, particularly during melting, casting, machining, grinding, welding, powder handling, etc. 8.2.4 Protective clothing
Always wear protective clothing when handling dusts and other particulates. Wear gloves to prevent contact with particulate or solutions. Wear gloves to prevent metal cuts and skin abrasions during handling. 8.2.5 Other protective equipment
Protective overgarments or work clothing must be worn by persons who may become contaminated with particulate 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 a controlled manner to prevent secondary exposure to workers of third parties, to prevent the spread of particulate to other areas, and to prevent particulate from being taken home by workers. 8.2.6 General hygiene measures
Wash hands well with soap and water after handling dusty materials. Wash contaminated clothing to avoid secondary contamination or contamination of other personnel. 8.3 Technical advice.
8.3.1 Ventilation and engineering controls

Whenever possible, the use of local exhaust ventilation or other engineering controls is the preferred method of controlling exposure to airborne particulate. Where utilized, exhaust inlets to the ventilation system must be positioned as close as possible to the source of airborne generation. Avoid disruption of the airflow in the area of a local exhaust inlet by equipment such as a man-cooling fan. Check ventilation equipment regularly to ensure it is functioning properly. Provide training on the use and operation of ventilation to all users. Use qualified professionals to design and install ventilation systems. 8.3.2 Work practises
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 or visual 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 and personal hygiene. These clothing and personal hygiene requirements help keep particulate from being spread to non-production areas or from being taken home by the worker. Never use compressed air to clean UDDEHOLM TOOLING SAFETY DATA SHEET

work clothing or other surfaces. Fabrication processes may leave a residue of particulate on the surface of parts, products or equipment that could result in employee exposure during subsequent material handling activities. As necessary, clean loose particulate from parts between processing steps. As a standard hygiene practice, wash hands before eating or smoking. To prevent exposure, remove surface scale or oxidation formed on cast or heat treated products in an adequately ventilated process prior to working the surface. 8.3.3 Wet methods
Machining operations are usually performed under a liquid lubricant/coolant flood which assists in reducing airborne particulate. However, the cycling through of machine coolant containing finely divided particulate in suspension can result in the concentration building to a point where the particulate may become airborne during use. Certain processes such as sanding and grinding may require complete hooded containment and local 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 Housekeeping & maintenance
Use vacuum and wet cleaning methods for particulate removal from surfaces. Be certain to de-energize electrical systems, 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 from surfaces as this activity can result in elevated exposures to airborne particulate. Follow the manufacturer’s instructions when performing maintenance on HEPA filtered vacuums used to clean hazardous materials.During repair or maintenance activities the potential exists for exposures to particulate in excess of the occupational standards. Under these circumstances, protecting workers can require the use of specific work practices 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. 8.5 Welding
In accordance with OSHA regulation 29 CFR 1910.252 welding of materials containing beryllium is regulated as follows: Welding or cutting indoors, outdoors, or in confined spaces involving beryllium containing base or filler metals shall be done using local exhaust ventilation and pressure-demand airline respirators unless atmospheric tests under the most adverse conditions have established that the workers’ exposure is within the acceptable concentrations defined by 29 CFR 1910.1000. In all cases, workers in the immediate vicinity of the welding or cutting operations shall be protected as necessary by local exhaust ventilation or airline respirators. 8.6 Exposure Characterization
Determine exposure to airborne particulate by air sampling in the employee breathing zone, work area, and department. Utilize an Industrial Hygienist or other qualified professional to specify the frequency and type of air sampling. Develop and utilize a sampling strategy which identifies the extent of exposure variation and provides statistical confidence in the results. Conduct an exposure risk assessment of processes to determine if conditions or situations exist which dictate the need for additional controls or improved work practices. Make air sample results available to employees. 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, a specialized, specific, immunological blood test, the beryllium blood lymphocyte proliferation test (BLPT), is available to assist in the diagnosis of beryllium related reactions. Individuals who have an abnormal BLPT are normally referred to a lung specialist for additional specific tests to determine if chronic beryllium disease is present.
