Introduction
Improper contact with or use of rust preventive oil can cause various health hazards, generally including skin damage, respiratory irritation, eye discomfort, digestive system injury, and effects on the nervous system. Components in rust preventive oil such as mineral oil and additives can irritate the skin; prolonged exposure may lead to dryness, roughness, and peeling. Some individuals may develop allergic dermatitis symptoms such as redness and itching.
Improper contact with or use of rust preventive oil can cause various health hazards, generally including skin damage, respiratory irritation, eye discomfort, digestive system injury, and neurological effects. A detailed analysis is as follows:
1. Skin Damage: Components in rust preventive oil such as mineral oil and additives can irritate the skin. Prolonged contact may lead to dryness, roughness, and peeling. Some individuals may develop allergic dermatitis symptoms such as redness, itching, and rashes. In severe cases, it may even cause skin fissures or ulcers.
2. Respiratory Irritation: Inhalation of volatile gases or oil mist from rust preventive oil can irritate the respiratory mucosa, causing coughing, sore throat, chest tightness, and other discomforts. Long-term exposure may damage the respiratory mucosal barrier, increase the risk of respiratory infections, and lead to chronic lung damage.
3. Eye Discomfort: If rust preventive oil splashes into the eyes, it can directly irritate the conjunctiva and cornea, resulting in redness, pain, tearing, and a foreign body sensation. Without prompt treatment, it may damage the corneal epithelium, impair vision, or even trigger ocular inflammation.
4. Digestive System Injury: Accidental ingestion of rust preventive oil can severely irritate the mucous membranes of the mouth, esophagus, and gastrointestinal tract, leading to nausea, vomiting, abdominal pain, and diarrhea. In severe cases, it may damage the gastrointestinal mucosa, causing bleeding or infection, posing serious health risks.
5. Neurological Effects: Long-term exposure to certain harmful substances in rust preventive oil may allow these chemicals to enter the body through skin absorption or inhalation, affecting nervous system function. Symptoms may include dizziness, headaches, fatigue, difficulty concentrating, and memory decline. In severe cases, more serious neurological damage may occur.
When handling rust preventive oil, protective equipment such as protective clothing, gloves, masks, and goggles should be worn. If any discomfort occurs, immediately leave the exposure environment and seek medical attention promptly.
