1) Precautions for handling
(1) If metals or metal compounds (dust, fume, etc.) are generated as a result of processing, heating, melting, or grinding this
product, etc., the face, clothing, etc. shall be protected appropriately and ventilation shall be properly done in order not to
exceed the exposure limits for the constituent elements. The hazardous properties of collected substances containing dust,
fumes, etc., corresponding to the state thereof (oxides of constituent elements transformed to powder, etc.), shall be
confirmed. For exposure limit values, the permissible exposure limit of “Japanese Society of Occupational Health”, of
“ACGIH: American Conference of Industrial Hygienists” or “OSHA PEL: Occupational Safety and Health Administration”
shall be used for reference purposes. The following are values of OSHA PEL.
