3. HAZARDS IDENTIFICATION

EMERGENCY OVERVIEW

IMMEDIATECONCERNS: Oxidizer. Contact withcombustibles may cause fire. Decomposes yielding oxygen that supportscombustion of organic matters and can cause overpressure if confined.

POTENTIAL HEALTHEFFECTS: Corrosive to eyes, nose, throatand lungs. May cause irreversible tissue damage to the eyes includingblindness. May cause skin irritation.

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 orophthalmologist immediately.

SKIN: Wash with plenty of soap and water. Get medicalattention if irritation occurs and persists.

INGESTION: Rinse mouth with water. Dilute by giving 1 or 2 glassesof water. Do not induce vomiting. Never give anything by mouth to anunconscious person. See a medical doctor immediately.

INHALATION: Remove to fresh air. If breathing difficulty ordiscomfort occurs and persists, contact a medical doctor.

NOTES TO MEDICALDOCTOR: Hydrogen peroxide at theseconcentrations is a strong oxidant. Direct contact with the eye is likely tocause corneal damage especially if not washed immediately. Carefulophthalmologic evaluation is recommended and the possibility of localcorticosteroid therapy should be considered. Because of the likelihood ofcorrosive effects on the gastrointestinal tract after ingestion, and theunlikelihood of systemic effects, attempts at evacuating the stomach via emesisinduction or gastric lavage should be avoided. There is a remote possibility,however, that a nasogastric or orogastric tube may be required for thereduction of severe distension due to gas formation.

5. FIRE FIGHTING MEASURES

FLASH POINT ANDMETHOD: Non-combustible

FLAMMABLE LIMITS: Non-combustible

AUTOIGNITIONTEMPERATURE: Non-combustible

EXTINGUISHINGMEDIA: Flood with water.

FIRE / EXPLOSIONHAZARDS: Product is non-combustible. Ondecomposition releases oxygen which may intensify fire.

FIRE FIGHTINGPROCEDURES: Any tank or containersurrounded by fire should be flooded with water for cooling. Wear fullprotective clothing and self-contained breathing apparatus.

SENSITIVITY TOSTATIC DISCHARGE: No data available

SENSITIVITY TOIMPACT: No data available

HAZARDOUSDECOMPOSITION PRODUCTS: Oxygen whichsupports combustion.

6. ACCIDENTAL RELEASE MEASURES

RELEASE NOTES: Dilute with a large volume of water and hold in a pondor diked area until hydrogen peroxide decomposes. Hydrogen peroxide may bedecomposed by adding sodium metabisulfite or sodium sulfite after diluting toabout 5%. Dispose according to methods outlined for waste disposal.Combustiblematerials exposed to hydrogen peroxide should be immediately submerged in orrinsed with large amounts of water to ensure that all hydrogen peroxide isremoved. Residual hydrogen peroxide that is allowed to dry (upon evaporationhydrogen peroxide can concentrate) on organic materials such as paper, fabrics,cotton, leather, wood or other combustibles can cause the material to igniteand result in a fire.

7. HANDLING AND STORAGE

HANDLING: Wear cup type chemical safety goggles and full-faceshield, impervious clothing, such as rubber, PVC, etc., and rubber or neoprenegloves and shoes. Avoid cotton, wool and leather. Avoid excessive heat andcontamination. Contamination may cause decomposition and generation of oxygengas which could result in high pressures and possible container rupture.Hydrogen peroxide should be stored only in vented containers and transferredonly in a prescribed manner (see FMC Technical Bulletins). Never return unusedhydrogen peroxide to original container, empty drums should be triple rinsedwith water before discarding. Utensils used for handling hydrogen peroxideshould only be made of glass, stainless steel, aluminum or plastic.

STORAGE: Store drums in cool areas out of direct sunlight andaway from combustibles. For bulk storage refer to FMC Technical Bulletins.

COMMENTS: VENTILATION:
Provide mechanical general and/or local exhaust ventilation to prevent releaseof vapor or mist into the work environment.

8. EXPOSURE CONTROLS / PERSONAL PROTECTION

ENGINEERINGCONTROLS: Ventilation should be providedto minimize the release of hydrogen peroxide vapors and mists into the workenvironment. Spills should be minimized or confined immediately to preventrelease into the work area. Remove contaminated clothing immediately and washbefore reuse.

PERSONAL PROTECTIVE EQUIPMENT

EYES AND FACE: Use cup type chemical goggles. Full face shield may beused.

RESPIRATORY: If concentrations in excess of 10 ppm are expected useapproved self-contained breathing apparatus. Do not use oxidizable sorbantssuch as activated carbon.

PROTECTIVECLOTHING: Liquid proof rubber or neoprenegloves. Rubber or neoprene footwear (avoid leather). Impervious clothingmaterials such as rubber, neoprene, nitrile or polyvinyl chloride (avoidcotton, wool and leather). Completely submerge hydrogen peroxide contaminatedclothing or other materials in water prior to drying. Residual hydrogenperoxide, if allowed to dry on materials such as paper, fabrics, cotton,leather, wood or other combustibles can cause the material to ignite and resultin a fire.
