Section 3 - Hazards Identification


Appearance: gray to yellow-green crystalline.
Danger! Reacts with water to form hydrogen sulfide, sulfur dioxide, and phosphoric acid. Flammable solid. Water-reactive. Causes severe eye and skin irritation. May ignite or explode on contact with moist air. Harmful if inhaled or swallowed. Causes respiratory tract irritation. Stench. May cause central nervous system effects.
Target Organs: Central nervous system, respiratory system, eyes, skin.

Potential Health Effects
Eye: Contact may cause severe eye irritation and possible eye damage.
Skin: Causes severe skin irritation.
Ingestion: Harmful if swallowed. May cause irritation of the digestive tract.
Inhalation: May cause respiratory tract irritation. Vapors may cause dizziness or suffocation. Inhalation of high concentrations may cause pulmonary edema. Higher exposures may cause the loss of sense of smell (anosmia). Inhalation overexposure may lead the CNS effect such as: headache, dizziness, weakness, confusion, sweating, nausea, and vomiting. Higher levels can cause seizures and death.
Chronic: Prolonged exposure to hydrogen sulfide may result in pulmonary edema.

Section 4 - First Aid Measures

Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid imme diately.
Skin: Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
Ingestion: Do not induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
Inhalation: Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician: Treat symptomatically and supportively.

Section 5 - Fire Fighting Measures

General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Vapors may form an explosive mixture with air. Vapors can travel to a source of ignition and flash back. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Will burn if involved in a fire. Water reactive. Material will react with water and may release a flammable and/or toxic gas. Containers may explode in the heat of a fire. Flammable solid. May ignite or explode on contact with steam or moist air. Dangerous fire hazard in the form of dust when exposed to heat or flame.
Extinguishing Media: Use dry sand or earth to smother fire. Water may be ineffective. Do NOT use straight streams of water. DO NOT USE WATER OR FOAM. For large fires, use dry sand, dry chemical, soda ash or lime or withdraw from area and let fire burn. For small fires, use dry chemical, soda ash, lime or dry sand.
Flash Point: Not available.
Autoignition Temperature: 142 deg C ( 287.60 deg F)
Explosion Limits, Lower:N/A
Upper: N/A
NFPA Rating: (estimated) Health: 2; Flammability: 1; Instability: 2; Special Hazard: -W-

Section 6 - Accidental Release Measures

General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: Clean up spills immediately, observing precautions in the Protective Equipment section. Avoid generating dusty conditions. Cover with sand, dry lime or soda ash and place in a closed container for disposal. Remove all sources of ignition. Use a spark-proof tool. Provide ventilation. Do not expose spill to water. A vapor suppressing foam may be used to reduce vapors.

Section 7 - Handling and Storage

Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Do not allow water to get into the container because of violent reaction. Minimize dust generation and accumulation. Ground and bond containers when transferring material. Use spark-proof tools and explosion proof equipment. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Keep away from heat, sparks and flame. Avoid ingestion and inhalation. Do not allow contact with water. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. Keep from contact with moist air and steam.
Storage: Keep away from sources of ignition. Store in a cool, dry, well-ventilated area away from incompatible substances. Keep away from water. Flammables-area. Keep away from acids. Keep containers tightly closed. Store away from alkalies. Separate from organic materials.

Section 8 - Exposure Controls, Personal Protection

Engineering Controls: Use explosion-proof ventilation equipment. Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits.
