Health Hazards Information -Recommended Personal Protective Equipment: Self-contained breathing
apparatus (SCBA); acid-type canister mask; goggles and face shield, rubber gloves and chemical
protective clothing.; Symptoms FoZlowing Exposure: Inhalation causes irritation of the nose and throat;
pulmonary edema may develop following severe exposure. Contact with skin or eyes causes sever
burns. Ingestion causes sever burns of mouth and stomach.; General Treatment for Exposure: Seek
immediate medical attention following all exposures to this chemical. INHALATION: Remove victim
to fresh air; if breathing has stopped, start mouth to mouth resuscitation. EYES: Flush with clean
running water for at least 15 minutes. Do not use any oils or ointments. SHIN: Flush with water; wash
with soap and water. INGESTION: Give victim large amounts of milk or water. Do not induce
vomiting. If victim begins to vomit, give milk or beaten eggs at onehour intervals.; Toxicity by
Inhalation (Threshold Limit Value): No data; Short-Tern wosure Limits: No data; Toxicity by
Ingestion: No data; Late Toxicity: No data; Vapor (Gas) Irritant Characteristics: No data; Liquid or
Solid Irritant Characteristics: No data; Odor Threshold No data.
Fire Hazards - Flash Point (deg. F): 215 OC; This value may be lower because of the presence of
phosphorus; Flampnable Limits in Air (56): Not pertinent; Fire Extinguishing Agents: Large amounts
of water; Fire Extinguishing Agents Not To Be Used Not pertinent; Special Hazardr of Combustion
Products: Toxic fumes include oxides of phosphorous and hydrogen chloride; Behavior in Fire:
Containers may rupture. The hot liquid is spontaneously flammable because of the presence of dissolved
phosphorus; Ignition Temperature (deg. F): 319; Electrical Hazard No data; Burning Rate: No data.
Chemical Reactivity - Reactivity with Water: Reacts vigorously to form hydrogen chloride
(hydrochloric acid); Reactivity with Common Materials: Corrodes metal except 316 stainless steel,
nickel, and Hastelloy; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics:
Flush with water and rinse with sodium bicarbonate or lime solution; Polymerization: Not pertinent;
Inhibitor of Polymerization: Not pertinent.
