The chemical name of the rapid penetrant T-70E (wetting agent OT) is sodium bis(2-ethylhexyl) sulfosuccinate, which belongs to anionic surfactants. According to the GHS classification of chemicals, this product is classified as Skin corrosion/irritation (Category 2) and Serious eye damage/eye irritation (Category 2), and is also categorized as Hazardous to the aquatic environment - long-term hazard (Category 3). This means that under normal industrial use, if appropriate protective measures are not taken, this product may cause adverse effects on human health and the aquatic ecological environment.
From the perspective of human health, the main routes of hazard for this product are skin contact and eye contact. Skin contact can cause irritation reactions, manifested as redness, itching, or a burning sensation; eye contact can cause severe eye irritation, leading to pain, tearing, conjunctival congestion, and other symptoms. Under normal use conditions, inhalation risk is relatively low, but if the workplace is poorly ventilated or if atomization occurs, inhaling vapors or mists may still cause respiratory discomfort. It is particularly important to emphasize that this product is not a highly toxic or carcinogenic substance, and its hazards are mainly local irritant effects. As long as safety operating procedures are strictly followed and personal protective equipment is properly worn, the risk is completely controllable.
From the perspective of environmental impact, this product is classified as Harmful to aquatic life with long lasting effects (H412). This means that if this chemical is directly discharged into rivers, lakes, or oceans, it may cause toxicity to aquatic organisms such as fish and plankton, and its impact has a certain persistence. Therefore, it is strictly prohibited to directly discharge the product or waste liquids containing this product into sewers, surface water, or groundwater systems. All wastes must be disposed of in accordance with relevant regulations by qualified professional institutions.
| Hazard Type | Hazard Statement | GHS Category |
|---|---|---|
| Skin irritation | H315 Causes skin irritation | Skin corrosion/irritation Category 2 |
| Eye irritation | H319 Causes serious eye irritation | Serious eye damage/eye irritation Category 2 |
| Aquatic environment hazard | H412 Harmful to aquatic life with long lasting effects | Hazardous to the aquatic environment - long-term hazard Category 3 |
Personal protective measures: During operation, wear chemically resistant protective gloves (such as nitrile rubber or neoprene gloves), chemical safety goggles or face shields, and chemical protective work clothes. In poorly ventilated areas or processes that may generate mists, it is recommended to wear a filtering respirator. Thoroughly wash exposed skin areas before and after work, and do not eat, drink, or smoke in the workplace.
Environmental management measures: The workplace floor should be covered with impermeable, corrosion-resistant materials and equipped with secondary containment facilities such as dikes or collection trenches. Any leaks should be immediately covered with inert absorbent materials (such as dry sand, vermiculite, etc.) and collected into dedicated sealed containers. Wastewater from cleaning the spill area must be collected and treated, and must not be discharged into the environment. All wastes should be sent to qualified professional institutions for incineration or physical/chemical treatment in accordance with hazardous waste regulations.
