The chemical composition of high-temperature penetrant JFC-M is isotridecyl alcohol polyoxyethylene ether, which is a nonionic surfactant. According to the Safety Data Sheet, its acute oral LD₅₀ in rats is > 2000 mg/kg, indicating low overall toxicity. However, its local irritation to skin and eyes should not be ignored—the primary irritation index (PII) on rabbit skin is 1.0 to 2.0, classified as mild irritation; on rabbit eyes, it is moderately irritating, causing eye discomfort, congestion, and tearing upon contact. Therefore, eye protection is of utmost importance during operation.
This product is strictly prohibited for use in food, pharmaceuticals, or any area involving direct human contact. When operating under high-temperature conditions, vapors may form flammable mixtures with air. The work area must be well-ventilated, and local exhaust ventilation should be installed if necessary. Additionally, the product must be strictly avoided from contact with strong oxidizers to prevent violent reactions, and kept away from strong acids, strong bases, and other incompatible substances.
According to the Safety Data Sheet provided by Guoli Chemical, the following personal protective equipment (PPE) must be worn when handling high-temperature penetrant JFC-M:
| Protection Area | Protective Equipment | Remarks |
|---|---|---|
| Eyes | Chemical safety goggles (mandatory) | Face shield should be added if there is a risk of splashing; moderate eye irritation, protection cannot be ignored |
| Hands | Nitrile rubber or neoprene gloves | Prolonged or repeated contact may cause skin degreasing and dermatitis |
| Body | Long-sleeved work clothing, chemical protective boots | Wear a permeation-resistant apron when necessary |
| Respiratory system | Self-priming filter-type gas mask or supplied-air respirator | Only required when ventilation is insufficient or vapors are generated at high temperatures |
Operating Procedures: Eating, drinking, or smoking is strictly prohibited in the work area. Hands must be thoroughly washed after operation. When handling the product in high-temperature containers, depressurize and confirm the temperature first to prevent burns from hot material splashing. Use explosion-proof pumps, valves, and ventilation equipment, and take measures to prevent static accumulation. Contaminated work clothing must be thoroughly washed before reuse.
Storage Conditions: Store in a cool, dry, well-ventilated dedicated warehouse, keep containers tightly closed, and keep away from fire, heat sources, and strong oxidizers. Avoid prolonged storage in extremely low-temperature environments (which may cause increased viscosity or stratification), and avoid direct sunlight and proximity to heating sources such as radiators. Packaging containers should be made of stainless steel, polyethylene, or carbon steel lined with epoxy resin; avoid using aluminum alloy containers. The storage area should be equipped with dikes or other emergency containment facilities for leaks, and strictly follow the "first-in, first-out" principle.
| Emergency Situation | Handling Method |
|---|---|
| Skin contact | Immediately remove contaminated clothing, rinse thoroughly with plenty of water and soap for at least 15 minutes. If irritation persists, seek medical attention. |
| Eye contact | Immediately open eyelids and rinse thoroughly with plenty of running water or normal saline for at least 15 minutes. After rinsing, seek medical attention immediately (do not use neutralizing agents). |
| Inhalation of vapors | Quickly move to fresh air and keep the airway open. Give oxygen if breathing is difficult. If breathing stops, perform artificial respiration immediately and seek medical attention. |
| Ingestion | Do not induce vomiting. If conscious, rinse mouth with water and drink a small amount of water to dilute. Seek medical attention immediately and provide the product label. |
| Leak | Contain and absorb with inert non-combustible materials such as sand, vermiculite, etc., and collect in closed containers. Do not discharge into sewers or waterways. |
| Fire | Use dry powder, carbon dioxide, water fog, or alcohol-resistant foam. Firefighters must wear self-contained positive-pressure breathing apparatus. |
