Description of first aid measures First-aid measures general : Call a physician immediately. First-aid measures after inhalation : Ifinhaled: Remove to fresh air. If breathing is difficult, administer oxygen. If not breathing, give artificial respiration, preferably mouth-to-mouth. GET MEDICAL ATTENTION IMMEDIATELY. Symptoms may be delayed. First-aid measures after skin contact If on skin: Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Get medical attention immediately. Do not reuse clothing and shoes until cleaned. Discard items which cannot be decontaminated, including leather articles such as shoes, belts and watchbands. Wash clothing before reuse. First-aid measures after eye contact If in eyes: Immediately flush eyes with plenty of water for at least 15 minutes while holding eyelids open. Tilt head to avoid contaminating unaffected eye. Get immediate medical attention. Remove contact lenses, if present and easy to do. Continue rinsing. Call a physician immediately. Do not interrupt flushing. Continue flushing with water during transport to emergency care facility. First-aid measures after ingestion : If swallowed: Call a physician immediately. DO NOT induce vomiting unless directed to do so by a physician. Never give anything by mouth to an unconscious person. If vomiting occurs spontaneously, keep head below hips to prevent aspiration of liquid into the lungs. Rinse mouth. Do not induce vomiting. Most important symptoms and effects (acute and delayed) Symptoms/effects after inhalation : CORROSIVE-CAUSES SEVERE IRRITATION AND BURNS. Vapors or mists may cause: Hoarseness. Respiratory irritation. Shortness of breath. burning sensation. Cough. Nausea. vomiting. Pulmonary edema. Symptoms of pulmonary edema can be delayed up to 48 hours after exposure. Prolonged or repeated exposure may cause: Nosebleeding. Bronchitis. Symptoms/effects after skin contact : CORROSIVE-CAUSES SEVERE IRRITATION AND BURNS. Contact with concentrated liquid for a short period of time may cause a temporary whitening or bleaching of the skin. Brief contact may cause: redness. swelling. Symptoms/effects after eye contact . . CORROSIVE-CAUSES SEVERE IRRITATION AND BURNS. May cause: Serious damage to eyes. redness. tearing. pain. stinging. corneal damage. Burns. Burns may not be immediately painful or visible for up to 24 hours. Symptoms/effects after ingestion : CORROSIVE-CAUSES SEVERE IRRITATION AND BURNS. May cause burns or irritation of the linings of the mouth, throat, and gastrointestinal tract. May cause: Gastric perforation. Burns to the gastric/intestinal mucosa. Abdominal pain, nausea. diarrhea. The rapid releasing of oxygen can cause distension and bleeding of the mucosa in the stomach and lead to severe damage of the intestinal organs, especially in the event of greater intake of the product. 3/26/2025 EN (English US) 3/11 Immediate medical attention and special treatment, if necessary : No specific antidote known. Treatment of overexposure should be directed at the control of symptoms and the clinical condition of the patient. Hydrogen peroxide is a strong oxidant. Direct contact with the eye is likely to cause corneal damage, especially if not washed immediately. Careful ophthalmologic evaluation is recommended and the possibility of focal corticosteroid therapy should be considered. Because of the likelihood of corrosive effects on the gastrointestinal tract after ingestion and the unlikelihood of systemic effects, attempts 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. Extinguishing media Suitable extinguishing media : Water only. Water spray. Water fog. Flood with plenty of water. Unsuitable extinguishing media : Do not use organic compounds. Specific hazards arising from the chemical Fire hazard : May intensify fire; oxidizer. Decomposition will release oxygen, which will intensify a fire. The rate of decomposition may exceed the vent capacity of storage containers and cause an explosion. Could be ignited by friction, heat, sparks or flames. Explosion hazard : Forms explosive mixtures with combustible, organic, or other easily oxidizable materials. : Toxic fumes may be released. Nitrogen oxides. Carbon oxides (CO, CO2). Sulfur oxides (SOx). Hazardous decomposition products Toxic fumes may be released. Nitrogen oxides. Carbon oxides (CO, CO2). Sulfur oxides (SOx). Firefighting instructions Evacuate personnel to a safe area. Do not enter fire area without proper protective equipment, including respiratory protection. Stay upwind/keep distance from source. Move containers from fire area if it can be done without personal risk. Use water spray or fog for cooling exposed containers. Protection during firefighting Do not attempt to take action without suitable protective equipment. Self-contained breathing apparatus. Complete protective clothing. |Personal precautions, protective equipment and emergency procedures Protective equipment Do not attempt to take action without suitable protective equipment. For further information refer to section 8: “Exposure controls/personal protection". Do not exceed the occupational exposure limits (OEL). Emergency procedures Evacuate unnecessary personnel. Stop leak if safe to do so. Ventilate spillage area. Environmental precautions Avoid release to the environment. Notify authorities if product enters sewers or public waters. iMethods and material for containment and cleaning up For containment Contain any spills with dikes or absorbents to prevent migration and entry into sewers or streams. Stop leak, if possible without risk. Eliminate sources of ignition. Methods for cleaning up Notify authorities if product enters sewers or public waters. Soak up residue with inert absorbent material. Place in non-leaking containers for immediate disposal. Flush remaining area with plenty of water to remove trace residue and dispose of properly. Spilled product must never be returned to the original container for recycling. Decontaminate tools, equipment and personal protective equipment in a segregated area. Large quantities: Contain large spillage with sand or earth. Dilute small spillage well and wash away with large quantities of water. 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 a fire.
