IV.   FIRE AND EXPLOSION HAZARDS DATA

Flash Point (Method used):  N/A

Autoignition Temperature:  N/A

Flammable Limits:  Upper:  N/A

Extinguishing Media:  None

Special Fire Fighting Procedures:  None

Unusual Fire & Explosion Hazards:  None

V.   HEALTH HAZARD DATA

Exposure Criteria:  No specific exposure limit for zinc silicate.  The OSHA limit for inert particulates is 15 mg/m³, while the TLV for inert particulates is 10 mg/m³.

Effects of Over Exposure:

Inhalation:  None expected.  Zinc compounds are considered to have a relatively low order of toxicity.  However, as a matter of good practice, exposure to high concentrations of dusts should be avoided.

Ingestion:  Unknown, not probably none for any kind of accidental ingestion likely to occur in an industrial environment since the phosphor is insoluble.

Skin or Eye Contact:  No adverse effects anticipated.

EMERGENCY AND FIRST AID PROCEDURES:  Non-emergency care anticipated.

VI.   REACTIVITY DATA

Stability:  Stable

Incompatibility (Material to Avoid):  None

Hazardous Decomposition Products:  None

Hazardous Polymerization:  Will not occur

VII.   SPILL OR LEAK PROCEDURES

Steps to Be Taken in Case Material Is Released or Spilled:  Use normal clean-up procedures, using a broom or vacuum, taking care to avoid excessive dusting.

Waste Disposal Method:  In accordance with Local, State and Federal Waste Disposal Regulations.

Hazardous Waste Classification:  Not classified.

VIII.   SPECIAL PROTECTION INFORMATION

Respiratory Protection (Specify Type):  If exposure may exceed permissible limits, use a NIOSH-approved respirator for toxic dusts having a TLV not less than 0.05 mg/m³.

Ventilation:  If necessary, use local exhaust ventilation to keep exposure levels below permissible limits for inert particulates.

Protective Gloves:  None

Eye Protection:  Safety Glasses

Other Protective Equipment:  None

IX.   SPECIAL PRECAUTIONS

Other Handling and Storage Conditions:  Store in a dry, cool, area.

The above information is believed to be correct, but does not purport to be all inclusive and shall be used only as a guide.  ESPI shall not be held liable for any damage resulting from handling or from contact with the above product.
