Under normal usage conditions, 84 disinfectant generally poses no major harm to the human body. However, if used improperly, it may cause harm.

84 disinfectant is a chlorine-based disinfectant with sodium hypochlorite as its main ingredient. It has strong oxidizing properties and can be used for disinfection of surfaces and environments. It provides relatively good bactericidal effects and is effective against bacterial spores, hepatitis virus, HIV, and other pathogens. However, 84 disinfectant also has certain corrosive, volatile, and irritating properties. Direct contact with undiluted disinfectant may cause skin redness, itching, and even blisters and inflammatory reactions. Meanwhile, during use, 84 disinfectant releases chlorine gas. Prolonged inhalation or exposure to high concentrations may cause symptoms such as coughing and rapid breathing, and in severe cases, may lead to respiratory diseases such as pulmonary edema. In addition, accidental ingestion of 84 disinfectant may cause gastrointestinal symptoms such as nausea and vomiting.

To ensure personal safety when using 84 disinfectant, please be sure to wear rubber gloves and a mask to avoid contact between the disinfectant and your skin or eyes. At the same time, properly dilute the disinfectant and ensure adequate indoor ventilation.
