Handling of shapes presents no dermatitis or skin absorption problem.

SECTION VI — EMPLOYEE PROTECTION______

Respiratory Protection: NIOSH approved high efficiency "cartridge or^uppiied air mask is required if Beryllium concentrationr iai n s exceeds OSHA standards.

Eye Protection: None required except as related to normal operations. Protective Gloves: None normally required. Other Protective Equipment; Personnel performing operations where there are exposures to dust, mists, or fumes shoul e providedb . * d full-body protectiv . e ^ clothing. =_.. . Ventilation: Provide adequate local exhaust ventilation when performing operations suc machinings ha , grinding, laser trimming, sand blasting, chemical.etching, etc. where respirabte dusts, mists, or fumes are generated. Powdered materials must.be stored in sealed containers; transfers must be made in ventilated hoods. Operations generating airborne materia lsampler musai e tb determino dt e exposure levels.

SECTION VII — FIRST AID

Skin Contact: Properly clean any contaminated clothing. Wash body especially under fold skif sd o finger nan - nails. Cove y operan n wound avoio st d infections. Dermatitis from handlin usualls gi y limited to abrasion. Eye Contact: Flush eye with Boric Solution for approximately 20 minutes. * fnhalatfon: Remove from source of exposure, have sinus cavities flushed by qualified physician. ingestfon: Fired, solid Beryllium Oxide Ceramics are indigestible.

_ fcautions for Handling and Storing: Store in closed containers. Handling solid Beryllium Oxide ceramics is harmless so long as they are kept dust-free. Avoid any operations which would create respirable dust or mists. Spill or Leak Precautions; Clean any loose material usjhg wet cleaning or properly equipped vacuum cleaner supplied with Hepa filters. Personnel involved in cleanup should wear proper~respirator and protective.clothing.
