The chemical name of rapid penetrant T-70E is sodium di(2-ethylhexyl) sulfosuccinate (70% solution), which is an anionic surfactant. According to the GHS classification criteria, this product belongs to skin irritation category 2 and serious eye damage/eye irritation category 2, and also poses long-term hazards to the aquatic environment (category 3). Therefore, during use, personnel protection and environmental protection are the two core concerns.
In actual operation, this product has excellent rapid penetration ability, but due to its high chemical activity, direct skin contact can cause irritation reactions, and splashing into the eyes may cause serious eye irritation. Operators must thoroughly wash exposed skin before and after operation. Work clothes must be stored separately and not taken out of the workplace. Eating, drinking, or smoking is strictly prohibited in the work area.
In terms of environmental protection, this product is harmful to aquatic organisms and has long-lasting effects. It is strictly prohibited to discharge the product or its waste liquid directly into sewers, surface water, or soil. All spills and waste packaging must be disposed of by qualified professional institutions in accordance with hazardous waste regulations.
| Protection area | Protective equipment requirements |
|---|---|
| Eyes/Face | Must wear compliant chemical safety glasses or face shield to prevent splashing into eyes |
| Hands | Must wear chemical-resistant protective gloves (recommended nitrile rubber or neoprene gloves); check integrity and permeability before use |
| Skin and body | Wear appropriate chemical protective clothing and protective shoes to avoid direct skin contact |
| Respiratory system | General special protection is not required; in case of poor ventilation or possible atomization, it is recommended to wear a filter-type gas mask |
Operation specifications: The workplace should be well-ventilated, and local exhaust ventilation should be installed in processes that may generate splashes or atomization. Operate gently to prevent splashing. Containers should be kept sealed when not in use. The work area must be equipped with emergency flushing equipment and absorbent materials.
Storage conditions: Must be stored in a cool, dry, well-ventilated dedicated warehouse, away from heat sources, sparks, and open flames, avoiding direct sunlight. The ambient temperature is recommended to be kept between 5°C and 35°C to prevent freezing or high-temperature deterioration. The container material must be compatible with the product. After opening, re-seal carefully and keep upright. Keep away from incompatible substances such as strong oxidizers, strong acids, and strong bases. Do not mix storage or transport with food and feed. The storage area should be equipped with emergency cleaning equipment and fire extinguishing equipment.
Skin contact: Immediately remove all contaminated clothing and rinse thoroughly with plenty of flowing water and soap for at least 15 minutes. If irritation persists, seek medical attention.
Eye contact: Immediately open the eyelids and rinse continuously with plenty of flowing water or saline for at least 15 minutes, and seek medical attention as soon as possible without delay.
Spill handling: For small spills, cover and absorb with inert absorbent materials (dry sand, vermiculite, etc.); for large spills, build dikes to control the area and transfer liquid with explosion-proof pumps. All rinse water must be collected and treated, not discharged into the environment.
Fire fighting: Suitable extinguishing agents include dry powder, carbon dioxide, foam, and water mist. Do not use direct water jets to impact the spill. Combustion may produce toxic fumes such as sulfur oxides and carbon oxides. Firefighters must wear positive-pressure self-contained breathing apparatus and full-body protective clothing.
