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

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

EXPOSURE CONTROLS/PERSONAL PROTECTION

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
