SECTION II - HAZARD IDENTIFICATION
Emergency Overview: POISON! DANGER! CORROSIVE. CAUSES SEVERE BURNS TO SKIN, EYES,
RESPIRATORY TRACT, AND GASTROINTESTINAL TRACT. MATERIAL IS EXTREMELY
DESTRUCTIVE TO ALL BODY TISSUES. MAY BE FATAL IF SWALLOWED. HARMFUL IF
INHALED.
Inhalation: Respiratory Tract Irritant may Cause serious burns on Acute Contact. Severe injury is Usually
Avoided by the Self-Limiting Coughing and Sneezing Symptoms.
Ingestion: Toxic! Corrosive to mucous membranes and may cause perforation or the esophagus and
stomach. Abdominal Pain, Nausea, Vomiting. General Gastro-Intestinal upset can be expected.
Skin: Irritant, Possibly Corrosive if contact is Prolonged. Soreness, Redness, Destruction of skin may
result.
Eye Contact: Irritant. Possibly Corrosive to Eye Tissue, Tearing, Redness, Pain, Impaired Vision are
Symptoms.
Development of a Defatting Dermatitis on Prolonged contact with Potassium Hydroxide has been
Chronic Exposure:
reported. Continued Irritation may lead to increased Susceptibility to Respiratory Illness.
Aggravated by Persons with Pre-Existing Skin Disorders or Eye Problems or Impaired Respiratory Function, or
Exposure: Impaired Liver or Kidney Function may be More Susceptible to the Effects of this Agent.
SECTION III - COMPOSITION / INFORMATION ON INGREDIENTS
CAS #: CHEMICAL NAME
Potassium Hydroxide (<45%)
1310-58-3
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: Immediately Flush Skin with Plenty of Water for at Least 15 Minutes. Call a Physician if Irritation
Develops.
Immediately Flush Eyes with Plenty of Water for at Least 15 Minutes, Lifting Upper and Lower
Eyes:
Eyelids Occasionally. Get Medical Attention Immediately.
SECTION V - FIRE FIGHTING MEASURES
Fire: Not considered to be a Fire Hazard
Explosion: Not considered to be a Explosion Hazard
Fire Extinguishing Media: Use any means Suitable for Extinguishing Surrounding Fire. Avoid direct contact of liquid with
water.
Special Information: In the Event of Fire, Wear Full Protective Clothing and NIOSH-Approved Self-Contained

Ventilate area or Leak or Spill. Remove all Sources of Ignition. 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. Use Non-
Sparking Tools and Equipment. Neutralize with Soda Ash or Lime and 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
Keep in a Tightly Closed Container. Protect from Physical Damage Stored in a Cool, Dry, and
Ventilated Area away from sources of heat, moisture and Incompatibilities. Store above 60潞F
(16潞C) to prevent freezing. Always add Caustic to Water while stirring. Never the reverse.
Containers of this Material may be Hazardous when Empty since they Retain Product Residues.
(Vapors, Liquid). Do Not Store with Aluminum or Magnesium.
SECTION VIII - EXPOSURE CONTROL / PERSONAL PROTECTION
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.
Airborne Exposure Limits: OSHA Permissible Exposure Limit (PEL) 2 mg/m鲁 (Ceiling) ACGIH Threshold Limit (TLV)
2 mg/m鲁 (Ceiling) .
Personal Respirators: A Full-Face piece Organic Vapor Respirator may be Worn up to 50 Times the Exposure Limit or
(NIOSH APPROVED) the Maximum Use Concentration Specified by the Appropriate Regulatory Agency or Respirator
Supplier, Whichever is Lowest. For Emergencies or Instances Where the Exposure Levels are
Not Known, Use a Full-Face piece Positive-Pressure, Air Supplied Respirator.
Skin Protection: Wear Impervious Protective Clothing, Including Boots, Gloves, Lab Coat, Apron or Coveralls, as
Appropriate, to Prevent Skin Contact. Neoprene and Nitrile Rubber are Recommended.
Use Chemical Safety Goggles and/or a Full Face Shield where Splashing is Possible. Maintain
Eye Protection:
Eye Wash Fountain and Quick-Drench Facilities in Work Area.
