Potential Health Effects

----------------------------------

Inhalation:

Vapors are corrosive and irritating to the respiratory tract. Inhalation of

mist may burn the mucous membrane of the nose and throat. In severe

cases, exposures may result in pulmonary edema and death.

Ingestion:

Corrosive and irritating to the mouth, throat, and abdomen. Large

doses may cause symptoms of abdominal pain, vomiting, and diarrhea

as well as blistering or tissue destruction. Stomach distention (due to

rapid liberation of oxygen), and risk of stomach perforation,

convulsions, pulmonary edema, coma, possible cerebral edema (fluid

on the brain), and death are possible.

Skin Contact:

Corrosive. Symptoms of redness, pain, and severe burn can occur.

Eye Contact:

Vapors are very corrosive and irritating to the eyes. Symptoms include

pain, redness and blurred vision. Splashes can cause permanent tissue

destruction.

Chronic Exposure:

No information found.

Aggravation of Pre-existing Conditions:

Persons with pre-existing skin disorders or eye problems or impaired

respiratory function may be more susceptible to the effects of the

substance.

4. First Aid Measures

Inhalation:

Remove to fresh air. If not breathing, give artificial respiration. If

breathing is difficult, give oxygen. Get medical attention immediately.

Ingestion:

If swallowed, DO NOT INDUCE VOMITING. Give large quantities

of water. Never give anything by mouth to an unconscious person. Get

medical attention immediately.

Skin Contact:

Immediately flush skin with plenty of water for at least 15 minutes

while removing contaminated clothing and shoes. Get medical

attention immediately. Wash clothing before reuse. Thoroughly clean

shoes before reuse. If allowed to dry on clothing, evaporation leads to

concentration and increased possibility of ignition.

Eye Contact:

Immediately flush eyes with plenty of water for at least 15 minutes,

lifting lower and upper eyelids occasionally. Get medical attention

immediately.

Note to Physician:

Pulmonary edema may be delayed for 24 to 72 hours;keep under

observation. Gastric lavage may be necessary if swallowed. Analysis

of body fluids (particularly gastric aspirates) using the titanium

chloride reaction, if done immediately, will reveal peroxides.

5. Fire Fighting Measures

Fire:

Not combustible, but substance is a strong oxidizer and its heat of

reaction with reducing agents or combustibles may cause ignition.

Increases the flammability of combustible, organic and readily

oxidizable materials.

Explosion:

Contact with oxidizable substances may cause extremely violent

combustion. Drying of concentrated hydrogen peroxide on clothing or

other combustible materials may cause fire or explosion. Sealed

containers may rupture when heated.

Fire Extinguishing Media:

Water spray may be used to extinguish surrounding fire and cool

exposed containers. Water spray will also reduce fume and irritant

gases.

Special Information:

In the event of a 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.

6. Accidental Release Measures

CAUTION! Caustic material. Causes fires with organic material.

Ventilate area of leak or spill. Wear appropriate personal protective

equipment as specified in Section 8. Contain and recover liquid when

possible. Do not return spilled material to original container.

Larger Spills: Dilute with a large amount of water and hold in a pond

or dyked area until the peroxide decomposes followed by discharge

into a suitable treatment system. May be neutralized with sodium

metabisulfite or sodium sulfite after diluting to 5-10% peroxide.

Do not flush undiluted material to sewer. This oxidizing material can

increase the flammability of adjacent combustible materials. Empty

containers should be rinsed with water before discarding.

7. Handling and Storage

Store in a cool(< 35C), well-ventilated dark area separated from

combustible substances, reducing agents, strong bases, not

store on wooden shelves or floors. Suggest rotation of stock.

Containers must be vented, but check periodically for bulging

containers which can burst from pressure. Protect containers from

physical damage, contamination, heat and incompatibles..

Contamination from any source (dust, metals) may cause rapid

decomposition with generation of large quantities of oxygen gas and

high pressures. Rinse empty containers thoroughly with clean water.

Glass, polyethylene, stainless steel and aluminum are recommended

materials for storage containers. Containers of this material may be

hazardous when empty since they retain product residues (vapors,

liquid); observe all warnings and precautions listed for the product.

8. Exposure Controls/Personal Protection

Airborne Exposure Limits:

-OSHA Permissible Exposure Limit (PEL):

1 ppm (TWA).

-ACGIH Threshold Limit Value (TLV):

1 ppm (TWA), A3: Animal carcinogen.

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. Please refer to the ACGIH document,

Industrial Ventilation, A Manual of Recommended Practices

, most

recent edition, for details.

Personal Respirators (NIOSH Approved):

If the exposure limit is exceeded, wear a supplied air, full- facepiece

respirator, airlined hood, or full-facepiece self-contained breathing

apparatus. This substance has unknown warning properties.

Skin Protection:

Wear impervious protective clothing, including boots, gloves, lab coat,

apron or coveralls, as appropriate, to prevent skin contact.

Eye Protection:

Use chemical safety goggles and/or a full face shield where splashing
