Skin:
Causes skin burns. Causes redness and pain.
Ingestion:
Harmful if swallowed. Causes digestive tract burns with immediate pain, swelling of the throat, convulsions, and possible coma.
Inhalation:
Harmful if inhaled. Causes chemical burns to the respiratory tract.
May cause burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting.

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 immediately. Do NOT allow victim to rub eyes or keep eyes closed.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
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. Call a poison control center.
Inhalation:
Remove from exposure and move to fresh air immediately. If breathing is difficult, give oxygen. Get medical aid. Do NOT use mouth-to-mouth resuscitation. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.
Notes to Physician:

Section 5 - FIRE FIGHTING MEASURES
General Information:
Evacuate area and fight fire from a safe distance. As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Water Reactive. Material will react with water and may release a flammable and/or toxic gas. Substance is noncombustible. Contact with water can cause violent liberation of heat and splattering of the material.
Extinguishing Media:
Do NOT use water directly on fire. Do NOT use alcohol foams. Use carbon dioxide or dry chemical. DO NOT USE WATER!

Section 6 - ACCIDENTAL RELEASE MEASURES
General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, observing precautions in the Protective Equipment section. Provide ventilation.

Section 7 - HANDLING and STORAGE
Handling:
Wash thoroughly after handling. Wash hands before eating. Follow all MSDS and label precautions even after container is emptied because they may contain product residues. Do not get in eyes, on skin, or on clothing. Keep container tightly closed. Do not ingest or inhale.
Do not allow contact with water.
Storage:
Store in a cool place in the original container and protect from sunlight. Store in a dry area. Heat can cause thermal decomposition and pressure build-up inside containers. Store protected from moisture. Store under nitrogen.

Section 10 - STABILITY AND REACTIVITY
Chemical Stability:
Stable. However, may decompose if heated. Combines vigorously with water with the evolution of heat.
Conditions to Avoid:
Contact with water.
Incompatibilities with Other Materials:
Reacts violently with water to yield phosphoric acid (H3PO4) and hydrochloric acid (HCl). The resulting acids can react with metals to yield hydrogen gas. Reacts violently or explosively with dimethyl sulfoxide and 2,6-dimethylpyridine N-oxide in the absence of diluent. Reaction with sodium metal may cause explosion. Zinc dust ignites on contact with phosphorus oxychloride, addition of water produces phosphine which ignites.
