High-temperature penetrant JFC-M (isomeric tridecanol polyoxyethylene ether) is a low-toxicity non-ionic surfactant. Its rat acute oral LD₅₀ value is greater than 2000 mg/kg, and it is classified as a non-hazardous chemical according to chemical classification standards. In daily industrial applications, as long as basic safety operating procedures are followed, the risk of this product to human health is controllable. However, it is not completely harmless—its irritation to rabbit eyes is moderate, and prolonged or repeated skin contact may cause defatting and dermatitis, so wearing protective goggles and gloves during operation is essential.
In terms of the environment, high-temperature penetrant JFC-M has slight harm to aquatic organisms. As a surfactant, it may affect the surface tension of water bodies after entering, interfering with the respiration and osmotic balance of aquatic organisms. Undiluted or unneutralized products entering drains, sewers, or natural water bodies may cause short-term adverse effects on local ecosystems. Therefore, used waste liquid and rinse water must be collected and treated and must not be directly discharged into the environment.
Overall, the safety of high-temperature penetrant JFC-M in industrial applications is guaranteed, with the key being standardized operation and proper waste disposal. As long as operators wear personal protective equipment, the workplace is well-ventilated, and waste liquid is not directly discharged, the harm to humans and the impact on the environment can be controlled at a very low level.

Eye Protection: Given the moderate eye irritation of the product, it is mandatory to wear chemical safety goggles during operation; for operations with splash risks such as material transfer and sampling, it is recommended to add a face shield.
Skin Protection: Wear chemical protective gloves made of nitrile rubber or neoprene, and long-sleeved work clothes. Wash hands thoroughly after operation; contaminated clothing must be washed before reuse.
Respiratory Protection: Under normal ventilation conditions, special respiratory protection is usually not required, but during high-temperature operation or when ventilation is insufficient, a self-priming filter-type gas mask should be worn.
Environmental Protection: Waste liquid and rinse water from production or use must be collected and treated, and must not be directly discharged into drains, sewers, or natural water bodies. In case of leakage, use inert materials such as sand, vermiculite to contain and absorb, collect as industrial waste, and dispose of it through qualified units.
