Section 3 Hazards Identification
Emergency Overview NOTICE!
*Causes skin and eye burns.
*Inhalation of vapor, mists and or aerosol is harmful and may cause delayed lung injury. Inhalation may be
fatal as a result of spasm, inflammation edema of Larynx, Bronchi, Chemical Pneumonitits or pulmonary
Edema. Symptoms of exposure may include burning sensation, coughing, wheezing, aryngitis, shortness of
breath, headache, nausea and vomiting. Chemical/Physical/toxicological properties have not been
determined.
*Harmful if swallowed
Section 4 First Aid Measures 鈥? Always Seek Medical if unsure of risks
2
Eye: Immediately flush with large quantities of running water (at least 20 minutes). Remove contacts if
worn and protect contaminating the victim鈥檚 healthy eye. Hold eyelids open while flushing. DO NOT
LET VICTIM RUB EYES. Do not use chemical agents to neutralize. Get Medical attention.
Skin: Use a clean dry cloth to wipe away excess material from skin. Flush contaminated area with plenty
of water. Do not attempt to neutralize with chemical agents. Get Medical attention. Remove
contaminated clothing, launder before reuse
Inhalation: If inhaled, Move to fresh air, rest, half upright position. Loosen clothing and give oxygen or
artificial respiration if not breathing give oxygen if there is difficulty breathing.
Ingestion: Do not induce vomiting. Call a physician or poison control immediately. Rinse mouth with
water, drink water. Never give anything to an unconscious person. Get Medical attention immediately
Note to Physician 鈥? Treat exposed patient symptomatically. Chemical burns on the skin should be treated
as thermal burns. Flush eyes with buffered or plain irrigating solutions. If any ulceration or conjctival
injury is present, have an ophthalmologist examine the patient. Iced water helps relieve some pain and
swelling on the skin. Aspiration of this product during induced emesis can result in sever lung injury.
Evaluate stomach contents using the method least likely to cause aspiration, such as gastric lavage after
endotracheal intubation. Ingestion of acid may affect the body鈥檚 pH balance which may affect the nervous
system.
Section 5 Fire and Explosion Data
Flammability:
Auto-Ignition Temperature: N/E
Flash Point: (COC), 230 F
Flammable Limits: N/E
Fire Fighting Media and Instructions SMALL FIRE: DO Not USE WATER, Dry Chemical (all
Or carbon dioxide extinguishing agents
LARGE FIRE: same as above
Fire Hazards: This material is not defined as flammable or combustible. However, it may
decompose under fire conditions to give off toxic materials such as phosphorus oxides, hydrogen chloride,
organic chlorides and flammable orgaic substitutes. Addition of water to the product can hydolyze
liberating acidic gas which in contact with metal surfaces can generate flammable and/or explosive
hydrogen gas.
Fire fighters should wear full face, self-contained breathing apparatus. Avoid breathing fumes or smoke.
Keep exposed containers cool with water spray to prevent rupture from excessive heat.
Combustion Products: Thermal decomposition products may include benzene phosphonic acid, carbon
dioxide, carbon monoxide, and hydrogen chloride.
Explosion Hazards: Reacts with water to produce hydrogen chloride. Hydrogen chloride in contact with
certain metals will produce flammable and explosive hydrogen gas.
Special Remarks: NA
Section 6 Accidental Release Measures
Small Spill: Stop source of spill. Dike area to keep spill from spreading. Ventilate enclosed areas to
prevent formation of toxic atmosphere. Evacuate all non-essential personnel (Especially upwind). Any
person entering or staying in the area should have a self-contained breathing apparatus NIOSH approved
with positive pressure. Wear protective clothing and gloves. Use absorbent to absorb the liquid than put in
waste container. Dispose of according to local/state laws and regulations.
Large Spill: same as above

Section 7 Handling and Storage
Precaution: Usual precautions for handling chemicals should be observed. Wear protective equipment
when handling. Wash thoroughly after handling.
Storage: Keep container closed. Suitable for general storage areas (less than 120 F) Keep away from food
stiffs or animal feed. Isolate from incompatible materials. Take extra care not to puncture drums.
General Comments: Do not open containers until ready for use. When dry the material is non corrosive to
stainless steel and other metal alloys. It becomes corrosive under moist conditions.
Section 8 Exposure Controls/Personal Protection
Engineering Controls: Usual precautions for handling chemicals should be observed
Personal Protection: Respiratory 鈥? Use a NIOSH approved organic vapor acid respirator (OVAG) with
dust, mist, and fume filters to reduce potential for inhalation exposure if conditions are generating mist,
dust or aerosol in non ventilated area. Where exposure necessitates a higher level of protection, use a
NIOSH approved, positive pressure pressure demand, air-supplied respirator. Follow all good practices
with regard to maintaining your respirator.
Personal Protection : Goggles should be worn when handling this material. A safety shower should be
available near the handling of this material. Protective clothing and gloves should be used.
Exposure Limits: No Limits have been determined by manufactures
