      In modern learning and office environments, highlighters have become a common tool for marking important information. Liquid highlighters, in particular, are popular for their bright colors and easy application properties. However, sometimes we may encounter liquid highlighter leakage, which will not only cause trouble to our work but may also have a certain impact on our health. This article aims to discuss the risk of liquid highlighter leakage and provide preventive measures and emergency treatment methods when leakage occurs.

      1. Structure and working principle of liquid highlighter

      Liquid highlighter mainly consists of the outer shell, inner core, and fluorescent liquid. The inner core is a porous material that absorbs and stores fluorescent liquid through capillary action, while the outer shell protects the inner core from damage. When using a highlighter pen, the fluorescent liquid will transfer to the paper as the inner core becomes wet, leaving a distinctive fluorescent trace.

      2. Possibility of liquid highlighter leakage

      Leaks can still occur if used improperly or if there are quality control issues during production. For example, if the outer shell is damaged or the inner core is excessively compressed and deformed, the liquid in the inner core may be squeezed out, causing leakage. In addition, highlighters that have not been used for a long time and are stored improperly may also cause internal structural damage due to the dry core, causing leakage.

      3. Risk of leakage

      The liquid in highlighters usually contains organic solvents and fluorescent dyes. These ingredients may be of low toxicity to the human body, especially for children, and may cause skin irritation, nausea, dizziness, and other symptoms after accidental exposure. Therefore, in the event of a leak, immediate measures should be taken to prevent the fluorescent liquid from coming into contact with the skin or being aspirated.

      4. Preventive measures

      To reduce the risk of liquid highlighter leakage, you can take the following precautions:

      4.1 When purchasing liquid highlighters, choose a reputable brand to ensure product quality.

      4.2 When using liquid highlighters, avoid applying excessive pressure or bending to avoid damaging the inner core or outer shell.

      4.3 Cap the pen promptly after use to keep the inner core moist and prevent it from drying out.

      4.4 When storing liquid highlighters, store them in a dry and cool place, away from high temperatures and direct sunlight.

      4.5 Check the status of the highlighter regularly. If any signs of damage to the outer casing or inner core are found, replace it with a new one in time.

      5. Emergency treatment

      If a fluorescent liquid leak unfortunately occurs, the following emergency measures should be taken immediately:

      5.1 Stop using the highlighter and carefully apply the remaining fluorescent liquid to paper or cloth to reduce further leakage.

      5.2 If fluorescent liquid comes into contact with skin or clothing, rinse immediately with plenty of water for at least 15 minutes, and clean with soap or detergent as much as possible.

      5.3 If a large amount of liquid leaks, paper towels or highly absorbent cloth should be used to absorb it, and the waste should be placed in a sealed bag to prevent the spread of harmful substances.

      5.4 Ventilate and ensure adequate fresh air circulation in the room.

      5.5 If you accidentally inhale the smell of fluorescent liquid or feel unwell, seek medical attention immediately.

      Although liquid highlighters are convenient and quick to use, they also carry the risk of leakage. By understanding its structure and workings, we can better recognize the potential for leaks and take appropriate precautions to reduce the risk. At the same time, in the event of a leak, correct emergency response knowledge is also the key to ensuring user safety. Therefore, while we enjoy the convenience brought by highlighters, we should not forget to remain vigilant about its potential risks and master the necessary prevention and response skills.
