Hydrogen Peroxide 50% – FIRST AID MEASURES

Eye Contact Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes.

Remove contact lenses, if present, after the first 5 minutes, then continue rinsing. Seek

immediate medical attention/advice.

Skin Contact Take off contaminated clothing. Rinse skin immediately with plenty of water for 15-20

minutes. Call a poison control center or doctor for further treatment advice.

Inhalation Move to fresh air. If person is not breathing, contact emergency medical services, then give

artificial respiration, preferably mouth-to-mouth if possible. Call a poison control center or

doctor for further treatment advice.

Ingestion Rinse mouth. Do not induce vomiting. If conscious, give 2 glasses of water. Get immediate

medical attention. Never give anything by mouth to an unconscious person.

Most important symptoms and effects, both acute and delayed

Hydrogen Peroxide irritates respiratory system and, if inhaled, may cause inflammation and

pulmonary edema. The effects may not be immediate. Overexposure symptoms are

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.

Indication of immediate medical attention and special treatment needed, if necessary

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

opthalmologic evaluation is recommended and the possibility of local corticosteroid therapy

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

of severe distension due to gas formation.

FIRE-FIGHTING MEASURES

Suitable Extinguishing Media Water. Do not use any other substance.

Specific Hazards Arising from the Chemical

In closed unventilated containers, risk of rupture due to the increased pressure from

decomposition. Contact with combustible material may cause fire

Hazardous Combustion Products On decomposition product releases oxygen which may intensify fire.

Explosion data

Sensitivity to Mechanical Impact Not sensitive.

Sensitivity to Static Discharge Not sensitive.

Protective equipment and

precautions for firefighters

Use water spray to cool fire exposed surfaces and protect personnel. Move containers from

fire area if you can do it without risk. As in any fire, wear self-contained breathing apparatus

and full protective gear.

ACCIDENTAL RELEASE MEASURES

COMPOSITION/INFORMATION ON INGREDIENTS

Formula HO – OH

Chemical name CAS-No Weight %

Hydrogen peroxide 7722-84-1 50

Water 7732-18-5 50

Occupational exposure limits, if available, are listed in section 8

Personal Precautions Avoid contact with skin, eyes and clothing. Wear personal protective equipment. Isolate and

post 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 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 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 by

adding sodium metabisulfite or sodium sulfite after diluting to about 5%.

HANDLING AND STORAGE

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. Provide

mechanical 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. Heavy

metals. 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.

Appropriate engineering controls

Engineering measures Ensure that eyewash stations and safety showers are close to the workstation location.

Ensure adequate ventilation.

Individual protection measures, such as personal protective equipment

Eye/Face Protection Use chemical splash-type monogoggles and a full-face shield made of polycarbonate,

acetate, polycarbonate/acetate, PETG or thermoplastic.

Skin and Body Protection For body protection wear impervious clothing such as an approved splash protective suit made of SBR rubber, PVC (PVC Outershell w/Polyester Substrate), Gore-Tex (Polyester

trilaminate w/Gore-Tex), or a specialized HAZMAT Splash or Protective Suite (Level A, B,

or C). For foot protection, wear approved boots made of NBR, PVC, Polyurethane, or

neoprene. Overboots made of Latex or PVC, as well as firefighter boots or specialized

HAZMAT boots are also permitted. DO NOT wear any form of boot or overboot made of

nylon or nylon blends. DO NOT USE cotton, wool or leather as these materials react rapidly

with higher concentrations of hydrogen peroxide. 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.

Hand Protection For hand protection, wear approved gloves made of nitrile, PVC, or neoprene. DO NOT

use cotton, wool or leather for these materials react RAPIDLY with higher concentrations of

hydrogen peroxide. Thoroughly rinse the outside of gloves with water prior to removal.

Inspect regularly for leaks.

Respiratory Protection If concentrations in excess of 10 ppm are expected, use NIOSH/DHHS approved

self-contained breathing apparatus (SCBA) or other approved air-supplied respirator (ASR)

equipment (e.g., a full-face airline respirator (ALR)). DO NOT use any form of air-purifying

respirator (APR) or filtering facepiece (dust mask), especially those containing oxidizable

sorbants such as activated carbon.

Hygiene measures Avoid breathing vapors, mist or gas. Clean water should be available for washing in case of

eye or skin contamination. .

General information Protective engineering solutions should be implemented and in use before personal

protective equipment is considered.
