SECTION 6. HEALTH HAZARD DATA
OSHA Permissible Exposure limited or ACGIN TLV-None established for magnesium fluorosilicate.The OSHA
PEL.and TLV of 2.5mg/m3 for an eight-hour ( ) mg-weighted-average,as fluoride,do apply, Magnesium
fluorosilicate is not considerde to be acancer-causing materials by OSHA,NOTSH, or IARC, ROUTES OF
ENTRY lungs(brouthing),ingestion(swallowing).
EFFECTS OF OUEREXPOSURE:
SHORT TERM:May cause irritation of the eyes or respiratory tract,swallowing fluoride dust may cause sallowing
nausea,dohydration and thirst,abdominal and muscular pain,omiting,diuorhea,weak pulse,
convulsions,and respiratory or tailurea.
LONG TIME: esposures higher than the nose,throut,and bronchial passuage,may cause bone changes
(fluorousis),stiffness of joints mottled teath,or eajeium metabolism disorders.

SECTION 7. SPILL LEAK,AND DISPOSAL INFORMATION
STRPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED:
If uncontaminated ,sweep up or collect,and rouse as product.If contaminated with materials collect in
suitable containers.
WASTE DISPOSAL,METHOD:
Contains soluble fluorides, consult state or Federal Environmental protection Agency for accepted disposal
procedures and disposal locating,Disposal in streams sewers may be contrary to relulations.
SECTION 8. SPECIAL PROTECTION INFORMATION
RESPIRATORY PROTECTION:If dust concentrations exceed recommended exposure limited,use RTOSHApproced dust respirators,with aproval TC-21C xxx,until feasible engineering controls are completed.If
exposures are higher than 25mg/m3 as F,use an air-supplied resplirator or self-contained breathing apparatus.
EYE PROTECTION:If dust concentratons exist,tight-fitting gogglas are recommonded to reduce dust exposure
to the eyes,or splash-proof goggles where there is a aplash hazard.
SKIN PROTECTION: protective clothing and/or equopment nesessary to procent repeated or prolonged contact
VENTILATION: Local exhaust or other ventilation thet will reduce dust cncentrations to less than
the recommended exposure lioit.
OTHER PROTECTIVE EQUIPMENT: Optional.
