2. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW:
鈥? Clear liquid with a sharp, pungent, vinegar-like odor.
鈥? Oxidizer.
鈥? Stabilized peracetic acid, an ingredient in this product, decomposes under fire conditions to release
oxygen that intensifies the fire.
鈥? Use water to keep fire exposed containers cool.
鈥? Severely irritating to skin and eyes.
POTENTIAL HEALTH EFFECTS: Liquid and mist are corrosive (causing burns); direct
contact could cause irreversible damage to eyes including blindness and/or irreversible destruction of skin
tissue. Vapor/mist will irritate nose, throat and lungs but will usually subside when exposure ceases.

4. FIRST AID MEASURES
EYES: Immediately flush with water for at least 15 minutes, lifting the upper and lower eyelids
intermittently. See a medical doctor or ophthalmologist immediately.
SKIN: Immediately flush with plenty of water while removing contaminated clothing and/or shoes, and
thoroughly wash with soap and water. Obtain immediate medical attention. Contact a medical doctor if
necessary.
INGESTION: Rinse mouth with water. Dilute by giving 1 or 2 glasses of water. Do not induce
vomiting. Never give anything by mouth to an unconscious person. See a medical doctor immediately.
INHALATION: Remove to fresh air. If breathing discomfort occurs and persists, see a medical
doctor. If breathing has stopped, give artificial respiration and see a medical doctor immediately.
NOTES TO MEDICAL DOCTOR: This product can be corrosive to skin, eyes and mucous
membranes. Consideration should be given to careful endoscopy as stomach or esophageal burns,
perforations or strictures may occur. Careful gastric lavage with an endotracheal tube in place should be
considered. Observation may be warranted. Treatment is controlled removal of exposure followed by
symptomatic and supportive care.
5. FIRE FIGHTING MEASURES
Page 2 of 12
Peracetic Acid 15/23 (79-21-0-1) Date: 11/10/2006
EXTINGUISHING MEDIA: Use water to keep fire exposed containers cool.
FIRE / EXPLOSION HAZARDS: Decomposition releases oxygen that can initiate or
promote combustion.
FIRE FIGHTING PROCEDURES: Use flooding quantities of water only. Use water spray
to keep fire exposed containers cool. Fight fire from protected location or maximum distance. Chemical
type extinguishers are not effective with peracetic acid or hydrogen peroxide, which are ingredients in this
product. Use proper personal protective equipment and positive pressure self contained breathing apparatus.
FLAMMABLE LIMITS: Not available
SENSITIVITY TO IMPACT: Not available
SENSITIVITY TO STATIC DISCHARGE: Not available
6. ACCIDENTAL RELEASE MEASURES
RELEASE NOTES: Approach release from upwind. Stop or control leak using special protective
clothing and positive pressure self-contained breathing apparatus. Control run off and isolate discharged
material for proper disposal. Do not allow undiluted material to enter storm or sanitary sewer systems.
Combustible materials exposed to hydrogen peroxide, an ingredient in this product, should be immediately
submerged in, or rinsed with, large amounts of water to ensure that all hydrogen peroxide is removed.
Residual hydrogen peroxide that is allowed to dry (upon evaporation hydrogen peroxide can concentrate)
on organic materials such as paper, fabrics, cotton, leather, wood or other combustibles can cause the
material to ignite and result in a fire.
7. HANDLING AND STORAGE
HANDLING: General - Transfer product from drums (IBC) to process in closed system
(hermetically) and if not possible use effective local exhaust ventilation.
Drums - Empty as thoroughly as possible. Triple rinse drum before disposal. Avoid contamination;
impurities accelerate decomposition. Never return product to original container.
IBCs (Tote) - IBCs should be emptied as thoroughly as possible and returned without rinsing.
STORAGE: Do not store near reducing agents, fuels or other non-compatible materials. Store in a
cool (less than 86掳F), dry, well ventilated area. Do not store in direct sunlight, or near sources of ignition or
heat. Do not double stack. Use first in, first out storage system. Containers must be vented.
COMMENTS: VENTILATION: Provide mechanical local exhaust ventilation to prevent release of
mist into the work area. If ventilation is inadequate or not available use acid gas cartridge or canister with
full face-piece.

Hydrogen Peroxide 1 ppm (TWA) 1 ppm (PEL)
Acetic Acid 15 ppm (STEL) 10 ppm (PEL)
2 mg/m3 (STEL) 1 mg/m3 (TWA)
Sulfuric Acid
ENGINEERING CONTROLS: Provide mechanical local exhaust ventilation to prevent
release of mist into the work area. If release is expected use respiratory protection.
PERSONAL PROTECTIVE EQUIPMENT
EYES AND FACE: Use cup type chemical goggles. Full face shield may be used.
RESPIRATORY: Use approved acid/gas cartridge or canister with full face-piece unless
break-through occurs, then use airline supplied or self contained breathing apparatus with full face-
piece.
PROTECTIVE CLOTHING: Rubber or neoprene footwear. Rubber or neoprene
aprons or full protective clothing. Hydrogen peroxide is an ingredient in this product; completely
submerge hydrogen peroxide contaminated clothing or other materials in water prior to drying.
Residual hydrogen peroxide, if allowed to dry on materials such as paper, fabrics, cotton, leather,
wood or other combustibles can cause the material to ignite and result in a fire.
GLOVES: Rubber or neoprene gloves. Thoroughly wash the outside of gloves with soap and
water prior to removal. Inspect regularly for leaks.

TARGET ORGANS: Eyes, skin, nose, throat, lungs
ACUTE EFFECTS FROM OVEREXPOSURE: No data available for the product.
Liquid may cause severe burns and irreversible tissue damage to eyes, including blindness. Inhalation of
peracetic acid vapors causes lacrimation and irritation of the mucous membranes, eyes and nasal passages.
CHRONIC EFFECTS FROM OVEREXPOSURE: No data available for the
product. The International Agency for Research on Cancer (IARC) has concluded that there is inadequate
evidence for carcinogenicity of hydrogen peroxide in humans, but limited evidence in experimental animals
(Group 3 - not classifiable as to its carcinogenicity to humans). The American Conference of Governmental
Industrial Hygienists (ACGIH) has concluded that hydrogen peroxide is a 鈥機onfirmed Animal Carcinogen
with Unknown Relevance to Humans鈥? (A3). Repeated inhalation of the mist may cause inflammation of the
upper respiratory tract, chronic bronchitis and etching of the dental enamel. Persons who are asthmatics
may be more sensitive to the effects of inhaled acid sulfates. The International Agency for Research on
Cancer (IARC) has concluded that occupational exposure to strong inorganic acid mists containing sulfuric
acid are carcinogenic to humans (Group 1). The American Conference of Governmental Industrial
Hygienists (ACGIH) has concluded that sulfuric acid, contained in strong inorganic acid mists, is a
鈥橲uspected Human Carcinogen鈥? (A2 - limited evidence of carcinogenicity in humans and sufficient evidence
of carcinogenicity in experimental animals with relevance to humans).
