Ingestion Rinse mouth. Do not induce vomiting. If conscious, give 2 glasses of water. Get immediatemedical attention. Never give anything by mouth to an unconscious person.
Hydrogen Peroxide irritates respiratory system and, if inhaled, may cause inflammation and
Most important symptoms and
pulmonary edema. The effects may not be immediate. Overexposure symptoms are
effects, both acute and delayed
coughing, giddiness and sore throat. In case of accidental ingestion, necrosis may result
from mucous membrane burns (mouth, esophagus and stomach). Oxygen rapid release
may cause stomach swelling and hemorrhaging, which may product major, or even fatal,
injury to organs if a large amount has been ingested.
In case of skin contact, may cause burns, erythema, blisters or even necrosis.
Hydrogen peroxide at these concentrations is a strong oxidant. Direct contact with the eye
Indication of immediate medical
is likely to cause corneal damage especially if not washed immediately. Careful
attention and special treatment
opthalmologic evaluation is recommended and the possibility of local corticosteroid therapy
needed, if necessary
should be considered. Because of the likelihood of corrosive effects on the gastrointestinal
tract after ingestion, and the unlikelihood of systemic effects, attemps at evacuating the
stomach via emesis induction or gastric lavage should be avoided. There is a remote
possibility, however, that a nasogastric or orogastric tube may be required for the reduction

- HYDROGEN PEROXIDE – HANDLING AND STORAGE
Personal Precautions Avoid contact with skin, eyes and clothing. Wear personal protective equipment. Isolate andpost spill area. Keep people away from and upwind of spill/leak. Eliminate all sources of
ignition and remove combustible materials.
Other Combustible materials exposed to hydrogen peroxide should be immediately submerged inor 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 fire.
Environmental Precautions See Section 12 for additional Ecological Information.
Methods for Containment Dike to collect large liquid spills. Stop leak and contain spill if this can be done safely. Small spillage: Dilute with large quantities of water.
Methods for cleaning up Flush area with flooding quantities of water. Hydrogen peroxide may be decomposed byadding sodium metabisulfite or sodium sulfite after diluting to about 5%.
Handling Use only in well-ventilated areas. Keep/Store away from clothing/ combustible materials. Wear personal protective equipment. Never return unused hydrogen peroxide to original

container. Contamination may cause decomposition and generation of oxygen gas which
could result in high pressures and possible container rupture. Empty drums should be triple
rinsed with water before discarding. Utensils used for handling hydrogen peroxide should
only be made of glass, stainless steel, aluminum or plastic. Pipes and equipment should be
passivated before first use. Hydrogen peroxide should be stored only in vented containers
and transferred only in a prescribed manner.
Storage Keep containers in cool areas out of direct sunlight and away from combustibles. Providemechanical general and/or local exhaust ventilation to prevent release of vapor or mist into
work environment. Containers must be vented. Keep/store only in original container. Store
rooms or warehouses should be made of non-combustible materials with impermeable
floors. In case of release, spillage should flow to safe area. Containers should be visually
inspected on a regular basis to detect any abnormalities (swollen drums, increases in
temperature, etc.).
Incompatible products Combustible materials. Copper alloys, galvanized iron. Strong reducing agents. Heavymetals. Iron. Copper alloys. Contact with metals, metallic ions, alkalis, reducing agents and
organic matter (such as alcohols or terpenes) may produce self-accelerated thermal
decomposition.

- DISPOSAL CONSIDERATIONS
Persistence and degradability Hydrogen peroxide in the aquatic environment is subject to various reduction or oxidationprocesses and decomposes into water and oxygen. Hydrogen peroxide half-life in
freshwater ranged from 8 hours to 20 days, in air from 10 – 20 hours, and in soils from
minutes to hours depending upon microbiological activity and metal contamination.
Bioaccumulation Material may have some potential to bioaccumulate but will likely degrade in most environments before accumulation can occur.
Mobility Will likely be mobile in the environment due to its water solubility but will likely degrade overtime.
Other Adverse Effects Decomposes into oxygen and water. No adverse effects.
Waste disposal methods Dispose of in accordance with local regulations. Can be disposed as waste water, when incompliance with local regulations.
US EPA Waste Number D001 D003
Contaminated Packaging Dispose of in accordance with local regulations.
Drums – Empty as thoroughly as possible. Triple rinse drums before disposal. Avoid
contamination; impurities accelerate decomposition. Never return product to original
container.
