Health hazards: Inhaling the vapor or mist of this product can cause strong irritation to the respiratory tract. Direct eye contact with liquids can cause irreversible damage or even blindness. Oral poisoning can cause abdominal pain, chest pain, difficulty breathing, vomiting, temporary movement and sensory disorders, and elevated body temperature. Individual cases present with visual impairment, epileptic spasms, and mild paralysis. Long term exposure to this product can cause contact dermatitis.

Explosive hazard: This product supports combustion and has strong irritant properties.

Emergency measures

Skin contact: Remove contaminated clothing and rinse with plenty of running water

Eye contact: Immediately lift the eyelids and thoroughly rinse with plenty of flowing water or saline solution for at least 15 minutes. Seek medical attention.

Inhalation: Quickly leave the scene and move to a place with fresh air. Keep the respiratory tract unobstructed. If breathing is difficult, administer oxygen. If breathing stops, immediately perform artificial respiration. Seek medical attention.

Ingestion: Drink plenty of warm water and induce vomiting. Seek medical attention

Fire protection measures

Hazardous characteristics: Explosive strong oxidizing agent. Hydrogen peroxide itself is non flammable, but it can react with combustibles to release a large amount of heat and oxygen, causing ignition and explosion. Hydrogen peroxide is most stable at a pH of 3.5-4.5 and is easily decomposed in alkaline solutions. It can also decompose when exposed to strong light, especially short wave radiation. When heated above 100 ℃, it begins to decompose rapidly. It forms explosive mixtures with many organic compounds such as sugar, starch, alcohols, petroleum products, etc., and can explode under impact, heat, or electric spark. Hydrogen peroxide rapidly decomposes upon contact with many inorganic compounds or impurities, leading to explosions and releasing large amounts of heat, oxygen, and water vapor. Most heavy metals (such as iron, copper, silver, lead, mercury, zinc, cobalt, nickel, chromium, manganese, etc.) and their oxides and salts are active catalysts, and dust, cigarette ash, carbon powder, rust, etc. can also accelerate decomposition. Hydrogen peroxide with a concentration exceeding 74% can produce a gas-phase explosion in a sealed container with an appropriate ignition source or temperature.

Harmful combustion products: oxygen, water

Fire extinguishing method: Firefighters must wear full body fire and gas protective clothing and extinguish the fire in the upwind direction. Try to move the container from the fire scene to an open area as much as possible. Spray water to keep the fire container cool until the fire is extinguished. If the container in the fire has changed color or produced sound from the safety relief device, it must be evacuated immediately. Fire extinguishing agents: water, mist water, dry powder, sand.

Emergency response to leakage

Quickly evacuate personnel from the contaminated area to a safe zone, isolate them, and strictly restrict their entry and exit. It is recommended that emergency responders wear self-contained positive pressure respirators and protective clothing. Cut off the leakage source as much as possible. Prevent the flow into restricted spaces such as sewers and drainage ditches. Minor leakage: Absorb with sand, vermiculite, or other inert materials. You can also rinse with a large amount of water, dilute the washing water, and put it into the wastewater system. Massive leakage: Construct embankments or dig pits to contain it. Spray like water cools and dilutes steam, protects on-site personnel, and dilutes leakage into incombustible materials. Transfer to a tanker or dedicated collector using a pump, and recycle or transport to a waste disposal site for disposal.

Handling and Storage

Precautions for operation: Closed operation, comprehensive ventilation. Operators must undergo specialized training and strictly adhere to operating procedures. It is recommended that operators wear self-priming filter type gas masks (full face shields), polyethylene gas protective clothing, and chloroprene rubber gloves. Keep away from sources of fire and heat, and smoking is strictly prohibited in the workplace. Keep away from flammable and combustible materials. Prevent steam leakage into the workplace air. Avoid contact with reducing agents and active metal powders. Handle with care during transportation to prevent damage to packaging and containers. Equip with corresponding types and quantities of fire-fighting equipment and emergency response equipment for leaks. Empty containers may contain residual harmful substances.

Storage precautions: Store in a cool and ventilated warehouse. Stay away from sources of fire and heat. The storage temperature should not exceed 30 ℃. Keep the container sealed. It should be stored separately from flammable materials, reducing agents, active metal powders, etc., and avoid mixing storage. The storage area should be equipped with emergency response equipment for leaks and suitable containment materials.

Transportation information

Packaging method: Large packaging: plastic drums (cans), with a pressure relief valve or vent on the top of the container, at least 10% margin inside the container, and a net weight of no more than 50 kilograms per drum (can). Reagent packaging: Plastic bottles, individually packed in plastic bags, and then packaged together in a calcium plastic box.

Transportation precautions: Sufficient stabilizer should be added to hydrogen peroxide. Hydrogen peroxide with a content of ≥ 40% must be approved by the railway bureau during transportation. Hydrogen peroxide shall be transported by all steel covered trucks in accordance with regulations. Reagent packaging (with a content<40%) can be handled as less than truckload. The designed barrels, cans, and boxes must pass packaging tests and be approved by the railway bureau; hydrogen peroxide with a content ≤ 3% can be transported under normal cargo conditions. During railway transportation, the dangerous goods loading table in the "Regulations for the Transport of Dangerous Goods" of the Ministry of Railways should be strictly followed for loading and unloading. During transportation, they should be shipped separately, and the container should be ensured not to leak, collapse, fall, or be damaged. It is strictly prohibited to mix with acids, flammable materials, organic materials, reducing agents, self igniting materials, wet flammable materials, etc. During transportation, the vehicle speed should not be too fast and overtaking should not be forced. During road transportation, the vehicle should be driven according to the prescribed route. Before and after loading and unloading, the transport vehicle should be thoroughly cleaned. Wash thoroughly and strictly prohibit the mixing of organic matter, flammable materials, and other impurities.
