SECTION II - HAZARD IDENTIFICATION
Emergency Overview: DANGER! CORROSIVE. CAUSES SEVERE IRRITATION AND BURNS TO EVERY AREA OF
CONTACT. HARMFUL IF SWALLOWED OR INHALED.
Inhalation: Inhalation is not an Expected Hazard Unless Misted or Heated to High Temperatures. Mist or
Vapor Inhalation can Cause Irritation to the Nose, Throat, and Upper Respiratory Tract. Severe
Exposures can Lead to a Chemical Pneumonitis.
Ingestion: CORROSIVE! May Cause Sore Throat, Abdominal Pain, Nausea, and Severe Burns of the
Mouth, Throat, and Stomach. Severe Exposures can Lead to Shock, Circulatory Collapse, and
Death.
Skin: CORROSIVE! Can cause Redness, Pain, and Severe Skin Burns.
Eye Contact: CORROSIVE! May Cause Redness, Pain, Blurred Vision, Eye Burns, and Permanent Eye
Damage.
No Information Found.
Chronic Exposure:
Persons with Pre-Existing skin Disorders or Eye Problems, or Impaired Respiratory Function
Aggravated by Exposure:
may be More Susceptible to the Effects of the Substance.
SECTION III - COMPOSITION / INFORMATION ON INGREDIENTS
CAS #: CHEMICAL NAME
Phosphoric Acid 75 to 95%
7664-38-2
SECTION IV - FIRST AID MEASURES
Inhalation: Remove to Fresh Air. If not Breathing, Give Artificial Respiration. If Breathing is Difficult, Give
Oxygen. Get Medical Attention.
Ingestion: DO NOT INDUCE VOMITING! Give Large Quantities of Water. Never Give Anything by Mouth to
an Unconscious Person. Get Medical Attention Immediately.
Skin: In Case of Contact, Immediately Flush Skin with Plenty of Water for at Least 15 Minutes while
Removing Contaminated Clothing and Shoes. Wash Clothing and Shoes Before Reuse.
Eyes: Immediately Flush Eyes with Plenty of Water for at Least 15 Minutes, Lifting Lower and Upper
Eyelids Occasionally. Get Medical Attention Immediately.
SECTION V - FIRE FIGHTING MEASURES
Fire: Not Considered to be a Fire Hazard. Contact with Most Metals Causes Formation of Flammable
and Explosive Hydrogen Gas.
Explosion: Not Considered to be an Explosion Hazard.
Fire Extinguishing Media: Use any Means Suitable for Extinguishing Surrounding Fire. Water Spray may be used to Keep
Fire Exposed Containers Cool. If Water is used, use in Abundance to Control Heat and Acid
Build-Up.
Special Information: In the Event of 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.
SECTION VI - ACCIDENTAL RELEASE MEASURES
Ventilate area of Leak or Spill. Wear Appropriate Personal Protective Equipment as Specified
in Section 8. Isolate Hazard Area. Keep Unnecessary and Unprotected Personnel from Entering.
Contain and Recover Liquid when Possible. Neutralize with Alkaline Material (Soda-
Ash, Lime), then Absorb with an Inert Material (e.g., Vermiculite, Dry Sand, Earth), and place
in a Chemical Waste Container. Do Not Use Combustible Materials, such as Saw Dust. Do Not

Flush to Sewer! US Regulations (CERCLA) Require Reporting Spills and Releases to Soil,
Water and Air in Excess of Reportable Quantities.
SECTION VII - HANDLING AND STORAGE
Store in a Cool, Dry, Ventilated Storage Area with Acid Resistant Floors and Good Drainage.
Protect from Physical Damage. Keep Out of Direct Sunlight and Away from Heat, Water, and
Incompatible Materials. Do Not Wash out Container and Use it for Other Purposes. Water Added
to Acid can Cause Uncontrolled Boiling and Splashing. Containers of this Material May
be Hazardous when Empty Since they Retain Product Residues (Vapors, Liquid).
SECTION VIII - EXPOSURE CONTROL / PERSONAL PROTECTION
OSHA Permissible Exposure (PEL) 1 mg/m3 (TWA) ACGIH Threshold Limit Value (TLV) 1mg/m3
Airborne Exposure Limits:
(TWA), 3 mg/m3 (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.
Personal Respirators: If the Exposure Limit is Exceeded, a Full Facepiece Respirator with High Efficiency Dust/Mist
(NIOSH APPROVED) Filter may be Worn up to 50 times the Exposure Limit or the Maximum use Concentration
Specified by the Appropriate Regulatory Agency or Respirator Supplier, Whichever is Lowest.
Emergencies Where Exposure Limits are Not Known, use Full-Facepiece Positive-Pressure
Air Supplied Respirator.
Skin Protection: Rubber or Neoprene Gloves and Additional Protection Including Impervious Boots, Apron, or
Coveralls, as Needed in Areas of Unusual Exposure to Prevent Skin Contact.
Use Chemical Safety Goggles and/or Full Face Shield where Splashing is Possible. Maintain
Eye Protection:
Eye Wash Fountain and Quick-Drench Facilities in Work Area.

SECTION X - STABILITY AND REACTIVITY
General Reactivity: Stable Under Ordinary Conditions of Use and Storage. Substance can Supercool Without
Crystallizing.
Hazardous Decomposition: Phosphorous Oxides may form when Heated to Decomposition.
Incompatibilities: Liberates Explosive Hydrogen Gas when Reacting with Chlorides and Stainless Steel. Can
React Violently with Sodium Tetrahydroborate. Exothermic Reactions with Aldehydes, Amines,
Amides, Alcohols and Glycols, Azo-Compounds, Carbonates, Esters, Caustics, Phenols and
Cresols, Explosives and Organic Peroxides. Phosphoric Acid Forms Flammable Gases with
Sulfides, Mercaptans, Cyanides and Aldehydes. It Also Forms Toxic Fumes with Cyanides,
Sulfide, Fluorides, and Halogenated Organics. Mixtures with Nitromethane are Explosive.
Will Not Occur.
