Rapid penetrant T-70E (wetting agent OT), with the chemical name sodium di(2-ethylhexyl) sulfosuccinate, is an anionic surfactant. According to GHS chemical classification standards, this product falls under skin corrosion/irritation (Category 2) and serious eye damage/eye irritation (Category 2), and also poses long-term hazards to the aquatic environment (Category 3). Operators must fully understand its hazardous characteristics and receive appropriate safety operation training before use.
During routine operations, the work area should be well-ventilated, and local exhaust ventilation should be installed if necessary. For personal protection, chemical safety goggles or face shields, chemical-resistant gloves (e.g., nitrile rubber or neoprene gloves), and chemical protective clothing and safety shoes must be worn. Eating, drinking, or smoking is strictly prohibited during operations; exposed skin areas should be thoroughly washed before and after handling. Containers must always be kept closed when not in use to prevent leaks and external contamination.
The product should be stored in a cool, dry, well-ventilated dedicated warehouse, with the ambient temperature recommended to be between 5°C and 35°C, away from heat sources, sparks, and open flames, and protected from direct sunlight. It should be kept away from incompatible materials such as strong oxidizers, strong acids, and strong bases, and must not be stored or transported together with food, beverages, or animal feed. In the event of a spill, the spill area should be immediately isolated, and inert absorbent materials (e.g., dry sand, vermiculite) should be used for collection, preventing the spill from entering sewers or surface waters.
