Tungsten wire itself is generally harmless at room temperature because it does not react easily with human tissue. However, in some cases, tungsten wire or its dust may cause harm to the human body. Here are some potential risks:
1. Inhalation risk: If the tungsten wire breaks or wears out, the fine particles or dust produced may be inhaled into the lungs, causing respiratory irritation or other health problems.
2. Skin contact: Direct contact with tungsten wire may cause skin irritation or scratches. If there is a wound on the skin, contact with tungsten wire may cause infection or other complications.
3. Eye injury: Tungsten wire debris entering the eye may cause irritation or damage the cornea.
4. High temperature risk: Tungsten wire is often used as a filament in light bulbs. When heated to a high temperature, it may cause severe burns if accidentally touched.
5. Special cases: For doped tungsten filaments (such as those used in light bulbs), although small amounts of potassium, silicon and aluminum oxides are added during the production process, the content of these substances is extremely low and their main function is to improve the performance of the tungsten filament (such as anti-sagging ability) rather than to have a direct impact on the human body. However, if a large amount of tungsten powder or dust is generated during use and inhaled by the human body, it may still cause adverse health effects.
For safety reasons, precautions should be taken when handling equipment containing tungsten filaments (such as old incandescent lamps), such as wearing appropriate personal protective equipment (PPE), including gloves and goggles, and ensuring that the work area is well ventilated. If the tungsten filament is broken or damaged, it should be carefully cleaned and properly disposed of to avoid direct contact and inhalation of dust.
