Respiratory Protection: When potential exposures are above the occupational limits shown in this MSDS, approved respirators must
be used as specified by an Industrial Hygienist of other qualified professional. Respirator users must be medically evaluated to
determine if they are physically capable of wearing a respirator. Quantitative an/or qualitative fit testing and respirator training must
be satisfactorily completed by all personnel prior to respirator use. Users of any style respirator training must be clean shaven on
those areas of the face where the respirator seal contacts the face. Exposure to unknown concentrations of fumes or dusts requires the
wearing of a pressure-demand airline respirator or pressure-demand self-contained breathing apparatus. Pressure-demand airline
respirators are recommended when performing jobs with high potential exposures such as changing filters in a bag house air cleaning
device.
Housekeeping: Vacuum and wet cleaning methods are recommended for dust removal. Be certain to de-energize electrical systems,
as necessary, before beginning wet cleaning. Vacuum cleaners with high efficiency particulate air (HEPA) filters are the recom-
mended type. The use of compressed air or brooms to remove dusts should be avoided as such an activity can result in unnecessary
short-term elevated exposures to airborne dusts.
Maintenance: During repair or maintenance activities the potential exists for exposures in excess of the occupational standard.
Under these circumstances, protecting workers can require the use of specific work practices or procedures involving the combined
use of ventilation, wet methods, respiratory protection, decontamination, special protection clothing, and when necessary, restricted
work zones.
Other Protective Equipment: No special protective equipment or clothing is requires when handling solid forms. Protective over
garments or work clothing must be worn by persons who may become contaminated with dusts, fumes, or powders during activities
such as machining, furnace rebuilding, air cleaning equipment filter changes, maintenance, etc. Contaminated work clothing and over
garments must be managed in such a manner so as to prevent secondary exposure to persons such as laundry operators and to prevent
contamination to personal clothing. Never use compressed air to clean work clothing.
Protective Gloves: Wear gloves to prevent cuts and skin abrasions during handling.
Eye Protection: Wear safety glasses, goggles, or face shield when risk of eye injury is present, particularly during machining,
grinding, etc.
Recommended Monitoring Procedures:
Environmental Surveillance: Exposure to airborne materials should be determined by having air samples taken in the employee
breathing zone, work area, and department. The frequency and type of air sampling should be as specified by an Industrial Hygienist
or other qualified professional. Air sample results should be make available to employees.
Medical Surveillance: Persons exposed to airborne concentrations of this material should be included in a periodic medical surveil-
lance program. The program should include examination of the skin and respiratory systems. Non-specific findings of skin rash, skin
granulomata, or respiratory signs or symptoms may indicate a reaction to this material. A minimum medical surveillance program
should include (1) skin examination, (2) respiratory history, (3) auscultation of the lungs, (4) spirometry (FVC and FEV), and (5)
periodic chest x-ray. In addition, a specialized, specific, immunological blood test, the beryllium blood lymphocyte proliferation test
(BLPT), is available ( on a limited basis to assist in the diagnosis) to screen beryllium-exposed persons for beryllium reactions. Note:
It should be recognized that BLPT has limited sensitivity for chronic beryllium disease. 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.
