When using the rapid penetrant Fast T-50H, the core safety points are: avoid skin and eye contact, do not discharge directly into water bodies, maintain ventilation during operation, and keep away from fire sources.

Product Hazard Overview

The rapid penetrant Fast T-50H (dioctyl sodium sulfosuccinate) belongs to anionic surfactants. According to GHS hazard classification, this product is categorized as skin corrosion/irritation Category 2 (H315: Causes skin irritation), serious eye damage/eye irritation Category 2 (H319: Causes serious eye irritation), and is harmful to aquatic life (H402).

In terms of physical hazards, this product is a non-flammable liquid with a flash point > 100 °C (closed cup) and no explosive properties. However, it should be noted that acute toxicity data show an oral LD₅₀ in rats of > 2000 mg/kg, which may cause gastrointestinal discomfort if swallowed; the 96h LC₅₀ for fish is approximately 10–100 mg/L, which is toxic to aquatic life. It is strictly prohibited to discharge the product or its solution directly into water environments.

Safe Handling Precautions

When handling the rapid penetrant Fast T-50H, strictly follow the following guidelines:

  • Personal protection: During operation, wear impermeable chemical protective gloves, safety glasses or face shield, and protective clothing to avoid direct contact with skin and eyes.
  • Ventilation requirements: The workplace should be well-ventilated, with local exhaust ventilation if necessary.
  • Ignition source control: Keep away from heat sources, sparks, and open flames. No smoking. Use non-sparking tools.
  • Behavioral guidelines: Do not eat, drink, or smoke during operation. Avoid swallowing and inhaling vapors or mists. Thoroughly wash hands and exposed skin after handling. Contaminated clothing should be washed before reuse.
  • Personnel training: Operators should receive specialized training and strictly follow operating procedures.
  • Environmental protection: Avoid release to the environment. Waste liquid must be treated in accordance with local regulations to prevent soil and water contamination.

Storage Conditions

  • Store in a cool, dry, well-ventilated warehouse, away from direct sunlight, and maintain temperature within the normal range.
  • Containers must be kept sealed. After opening, re-seal promptly to prevent leakage and evaporation.
  • Store separately from incompatible substances such as strong oxidizers and acids, avoiding contact (this product is not resistant to strong acid or alkali environments).
  • The storage area should be equipped with spill containment trays, emergency spill response equipment, and fire extinguishing equipment.
  • Keep container labels clearly legible, and do not store together with food, feed, etc..

Emergency Response Measures

First Aid Measures

Type of ContactTreatment Method
Skin contactImmediately remove contaminated clothing and flush thoroughly with plenty of running water and soap for at least 15 minutes. If irritation symptoms occur, seek medical attention immediately.
Eye contactImmediately lift eyelids and flush continuously with running water or saline solution for at least 15 minutes, and seek medical attention immediately.
InhalationMove the person to fresh air and keep the airway clear. If feeling unwell or having difficulty breathing, seek medical attention immediately.
IngestionRinse mouth with water or mild saline. Do NOT induce vomiting (unless instructed by medical personnel). Seek medical attention immediately and show the container or label.

Fire Fighting Measures

Although this product is a non-flammable liquid, it may release irritating vapors when heated. Suitable extinguishing media: water spray, alcohol-resistant foam, dry powder, or carbon dioxide. Firefighters must wear positive-pressure self-contained breathing apparatus and full protective clothing. Prevent fire-fighting water from directly entering sewers or water bodies; collect and treat before discharge.

Spill Emergency Procedures

Immediately evacuate unrelated personnel to a safe area and eliminate all ignition sources. For small spills, absorb with sand, vermiculite, or other inert absorbent material, collect in a sealed container and dispose of as hazardous waste; for large spills, construct dikes or pits to contain, transfer to a dedicated container using an explosion-proof pump for recovery or disposal. The spill area should be well ventilated. When rinsing residues, avoid contaminating groundwater.

Special Reminders

Since this product is not resistant to strong acid or alkali environments, it should be used under neutral and mild acid-base conditions to ensure optimal performance and reduce the risk of unexpected reactions. Waste liquid treatment must strictly comply with local environmental regulations and must not be discharged arbitrarily.
