3. Hazards Identification

Emergency Overview
--------------------------
DANGER! CORROSIVE. MAY BE FATAL IF SWALLOWED OR INHALED. CAUSES BURNS TO ANY AREA OF CONTACT. MAY CAUSE DELAYED LUNG INJURY. WATER REACTIVE. CONTACT WITH WATER OR MOIST AIR LIBERATES CORROSIVE HYDROCHLORIC AND PHOSPHORIC ACID AND MAY CAUSE FLASH FIRES. STRONG OXIDIZER. CONTACT WITH OTHER MATERIAL MAY CAUSE FIRE.


Potential Health Effects
----------------------------------

Inhalation:
Corrosive. Extremely destructive to tissues of the mucous membranes and upper respiratory tract. Symptoms may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting. Inhalation may be fatal as a result of spasm inflammation and edema of the larynx and bronchi, chemical pneumonitis and pulmonary edema.

Ingestion:
Corrosive, causes severe burns. Forms hydrochloric and phosphorous acids by hydrolysis. Symptoms include abdominal pain, vomiting, diarrhea. Aspiration of the swallowed product or vomitus can cause severe pulmonary complications. Ingestion may be fatal.

Skin Contact:
Corrosive, causes severe burns. Local pain, redness, and possible acid burns on acute or prolonged contact. Vapors can cause irritation, as seen by redness and swelling.

Eye Contact:
Corrosive, causes severe burns. Vapors can cause pain, redness, and blurred vision. Irreversible eye damage can occur from vapors and liquid splashes.

Chronic Exposure:
Chronic ingestion or inhalation may induce systemic phosphorous poisoning. Liver damage, kidney damage, jaw/tooth abnormalities, blood disorders and cardiovascular effects can result.

Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or eye problems, jaw/tooth abnormalities, or impaired liver, kidney or respiratory function may be more susceptible to the effects of the substance.


4. First Aid Measures

Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention immediately.

Ingestion:
If swallowed, DO NOT INDUCE VOMITING. Give large quantities of water. Never give anything by mouth to an unconscious person. Get medical attention immediately.

Skin Contact:
Wipe off excess material from skin then immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Get medical attention immediately. Wash clothing before reuse. Thoroughly clean shoes before reuse.

Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately.


5. Fire Fighting Measures

Fire:
Non-flammable but reacts exothermically with water and may produce flashes of fire. Substance is a strong oxidizer and its heat of reaction with reducing agents or combustibles may cause ignition.

Explosion:
Not considered to be an explosion hazard.

Fire Extinguishing Media:
Dry chemical, foam or carbon dioxide. Do not use water.

Special Information:
In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode. In contact with water, may be an ignition source. Reacts with water to produce hydrochloric acid and phosphoric acid. The reaction may lead to flash fires die to the spontaneous ignition of diphosphine. Hydrochloric and phosphoric acid will react with most common metals except nickel and lead, to form flammable and potentially explosive hdrogen gas.


6. Accidental Release Measures

Ventilate the area of the leak or spill. Clean-up personnel require protective clothing and respiratory protection from vapors. Keep out of sewers and surface waters. Contain spill and collect if possible. Arrange with supplier to ship back recovered material for reclamation. If recovery is not possible, cover spill with dry sand. Cover this with excess soda ash/slaked lime (1:1 mix). Cautiously spray with a small amount of water (exothermic reaction), then saturate with water and mix. US Regulations (CERCLA) require reporting spills and releases to soil, water and air in excess of reportable quantities. The toll free number for the US Coast Guard National Response Center is (800) 424-8802.


7. Handling and Storage

Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage and moisture. Isolate from any source of heat or ignition. Avoid storage on wood floors. Separate from incompatibles, combustibles, organic or other readily oxidizable materials. Isolate from incompatible substances. Keep away from water. Containers of this material may be hazardous when empty since they retain product residues (vapors, liquid); observe all warnings and precautions listed for the product.


8. Exposure Controls/Personal Protection

Airborne Exposure Limits:
-OSHA Permissible Exposure Limit (PEL): 0.5 ppm (TWA) -ACGIH Threshold Limit Value (TLV): 0.2 ppm (TWA), 0.5 ppm (STEL)

Ventilation System:
A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details.

Personal Respirators (NIOSH Approved):
If the exposure limit is exceeded, wear a supplied air, full-facepiece respirator, airlined hood, or full-facepiece self-contained breathing apparatus. This substance has unknown warning properties.

Skin Protection:
Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact.

Eye Protection:
Use chemical safety goggles and/or a full face shield where splashing is possible. Maintain eye wash fountain and quick-drench facilities in work area.

10. Stability and Reactivity

Stability:
Stable under ordinary conditions of use and storage.

Hazardous Decomposition Products:
Hydrogen chloride, hydrochloric and phosphorous acids at high temperatures or in contact with water. Thermal decomposition products may also include phosphine and diphosphine.

Hazardous Polymerization:
Will not occur.

Incompatibilities:
Water, potassium or sodium metal, strong oxidants, hydroxylamine, nitric acid, alcohols, fluorine and lead oxide. Phosphorous trichloride is corrosive to most common construction materials, especially if moisture is present. (Steel corrosion at 0.5 - 3 mils per year would be expected).

Conditions to Avoid:
Moisture and incompatibles.
