ignition source is a potential dust explosion hazard.

Specific methodsï¼?--

The protection of firefighters：wear full protective clothing and NIOSH-approved self-contained

breathing apparatus with full facepiece operated in the pressure demand or other positive pressure

mode.



6. ACCIDENTAL RELEASE MEASURES

Personal precautions：Wear appropriate personal protective equipment

Environmental precautionsï¼?--

Methods for cleaning up：Sweep up and containerize for reclamation or disposal. Vacuuming or

wet sweeping may be used to avoid dust dispersal.



7. HANDLING AND STORAGE

Handling：Containers of this material may be hazardous when empty since they retain product

residues (dust, solids); observe all warnings and precautions listed for the product.

Storage：Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against

physical damage. Isolate from incompatible substances.

Personal protective equipmentï¼?

˙respiratory protection

   respiratory protection：If the exposure limit is exceeded, a half-face dust/mist

respirator may be worn for up to ten times the exposure limit or the maximum use

concentration specified by the appropriate regulatory agency or respirator supplier,

whichever is lowest. A full-face piece dust/mist respirator may be worn up to 50

times the exposure limit, or the maximum use concentration specified by the

appropriate regulatory agency, or respirator supplier, whichever is lowest. For
