CONDITIONS TO AVOID                            Inhalation of dust.



SECTION VI � HEALTH HAZARD DATA



CARCINOGENICITY                        This product contains crystalline silica; there is evidence of delayed respiratory

                                       disease (silicosis) if inhaled over a long period of time. IRAC, NTP, and

                                       California Proposition 65 conclude that inhaled crystalline silica causes cancer.

                                       This product contains a small amount of Titanium Dioxide as a natural part of

                                       the clay’s composition. This has been listed by NIOSH as a potential

                                       carcinogen. Respirable Quartz: OSHA PEL: TWA-TLV = 0.1mg/m³, ACGIH

                                       TLV=0.1mg/m³, NIOSH TWA =0.05 mg/ m³.



PRIMARY ROUTES OF ENTRY                Inhalation (dry form only), ingestion and dermal.



SUMMARY OF RISKS                       Individuals with a lung disease/condition (e.g.: bronchitis, emphysema,

                                       chronic pulmonary disease) can be aggravated by exposure.



EMERGENCY FIRST AID                    No specific first aid is necessary since the adverse health effects associated

                                       with this compound results from chronic exposures.



       Eye Contact:                    May be an irritant, flush eyes with generous amounts of water for at least 15

                                       minutes; call a physician if irritation persists.



       Skin Contact:                   May cause local dermatitis, which is relieved when removed.



       Ingestion                       Toxicity due to ingestion is low.



       Inhalation                      Remove to fresh air, call a physician if irritation due to inhalation persists.



       Physician’s Note                None



SECTION VII - PRECAUTIONS FOR SAFE HANDLING AND USE



Spills or Release Procedure    Follow normal clean-up procedures. Care should be taken to avoid causing dust to
