IV      FIRE AND EXPLOSION HAZARDS DATA



Flash Point (Method used): N/A                                                 Autoignition Temperature: No data

Flammable Limits: N/AUpper: N/A              Lower: N/A                        Unusual Fire & Explosion Hazard: N/A



Extinguishing Media: Flammable solid. Do not use water. Use dry chemical extinguishing agents, dry sand, or dry dolomite.



Special Fire Fighting Procedures: Finely powdered iron disulfide, especially in the presence of moisture, will rapidly heat spontane-

ously and ignite, particularly in contact with combustible materials. Use normal procedures which include wearing NIOSH/MSHA

approved self-contained breathing apparatus, flame and chemical resistant clothing; hats, boots and gloves. If without risk, remove

material from fire area.





V       HEALTH HAZARD INFORMATION



OSHA (PEL): None established                                                   ACGIH (TLV): None established



Animal Toxicity: LD50: No data; LC50: No data; Other: No data



Effects of Exposure:



Acute Effects: Ingestion: May cause irritation to the gastrointestinal tract if swallowed.

Skin Contact: May cause irritation. Skin absorption is unlikely.

Eye Contact: May cause irritation.

Inhalation: May cause irritation.

Other Health Hazards: Little toxic action except through the liberation of hydrogen sulfide.

Most Likely Routes of Entry: Ingestion.



Chronic Effects: Ingestion: None known

Skin Contact: None known

Eye Contact: None known

Inhalation: None known

Other: Not listed as a carcinogen by IARC or NTP.

EMERGENCY AND FIRST AID PROCEDURES:



EYE: Immediately flush eyes, including under eyelids, with large amounts of water for at least 15 minutes. Call a physician.
