Section IV 鈥? Fire and Explosion Hazard Data
Flash Point (Method Used): Not applicable Flammable Limits: LEL (Lower Explosive Limit) - N/A
UEL (Upper Explosive Limit) - N/A
Extinguishing Media: Suitable extinguishing agents. CO2, extinguishing powder, or water spray.
Special Fire Fighting Procedures: Fight larger fires with water or alcohol resistant foam. Firefighters should wear
protective equipment and self-contained breathing apparatus. As with most organic solids, fire is possible at elevated
temperatures or by contact with an ignition source.
Unusual Fire and Explosion Hazards: During heating or in case of fire, poisonous gases are produced. Fine dust
dispersed in air in sufficient concentrations, and in the presence of an ignition source is a potential dust explosion hazard.
Section V 鈥? Reactivity Data
Unstable Conditions to Avoid: Stable under ordinary conditions of use and storage.
Stability:
Hygroscopic.
Stable X
Incompatibility (Materials to Avoid): Reacts with oxidizing agents, Potassium chlorate, Potassium nitrite, Sodium-
Potassium powder, and Sodium hypochlorite.
Hazardous Decomposition or Byproducts: Carbon monoxide (C0), Carbon dioxide (CO2), and Sodium oxide may form
when heated to decomposition. May emit ammonia.
May Occur Conditions to Avoid: Heat, flame, ignition sources, dust and incompatible
Hazardous
materials.

Section VI 鈥? Health Hazard Data
Inhalation? Yes Skin? Yes Ingestion? Yes
Route(s) of Entry:
Irritant. Irritating to eyes, respiratory system, and skin. May be harmful if swallowed.
Health Hazards:
(Acute and Chronic)
Carcinogenicity: NTP? No IARC Monographs? No OSHA Regulated? No
(National Toxicology Program) (International Agency for Research in Cancer)
Signs and Symptoms of Exposure: If large doses are ingested, can cause vomiting, diarrhea, and prostration.
Inhalation of large amounts of dust may cause irritation to the respiratory tract. Symptoms may include coughing or
shortness of breath. Possible irritation on prolonged contact with moist or sensitive areas of the skin.
Medical Conditions Generally Aggravated by Exposure: May be irritating to mucous membranes and respiratory
tract. The toxicity of phosphates is their ability to sequester calcium. Chronic exposure of phosphates may sequester
calcium and cause calcium phosphates deposits in the kidneys.
Ingestion: If swallowed, seek medical attention.
Emergency /
First Aid
Inhalation: Supply fresh air or oxygen. Seek medical attention.
Procedures:
Eye Contact: Rinse opened eye for at least 15 minutes under running water. Seek medical attention.
Skin Contact: Wash with plenty of soap and water for 15 minutes. Seek medical attention.
Section VII 鈥? Precautions for Safe Handling and Use
Accidental Release Measures: Ventilate spill area. Avoid raising dust. Wear suitable protective clothing. Wipe up with
damp sponge or mop. Avoid contact with skin, eyes, and clothing.
Waste Disposal Method: Dispose in accordance with all applicable federal, state, and local environmental regulations.
Handling and Storing: Keep container tightly closed. Protect from moisture and physical damage. Suitable for any
general chemical storage area. Store away from oxidizing agents. Containers of this material may be hazardous when
empty since they retain product residues.
Other Precautions: Prevent formation of dust. Ensure good ventilation / exhaustion at the workplace. Avoid prolonged
or repeated exposure.
Section VIII 鈥? Control Measures
Respiratory Protection (Specify Type): None required where adequate ventilation conditions exist. If airborne
concentration is high, use an appropriate respirator or dust mask.
Local Exhaust: 50 鈥? 100 CFM Special: N/A
Ventilation:
Mechanical (General): N/A Other: N/A
Protective Gloves: Proper disposable gloves Eye Protection: Chemical resistant safety goggles
Other Protective Clothing or Equipment: Uniform, lab coat, or disposable lab wear.
Work / Hygienic Practices: Follow the usual precautionary measures for handling chemicals / powder. Keep away from
food and beverages. Immediately remove all soiled and contaminated clothing. Avoid contact with eyes, skin, and
clothing.
