Sodium hydroxide harm to the human body and first aid measures

Folding damage to the human body:
Sodium hydroxide is a white crystal that is highly irritating and corrosive at room temperature. Dust or smoke can irritate the eyes and respiratory tract, corrode the nasal septum, direct contact between the skin and the eyes, and sodium hydroxide can cause burns. Eating can cause gastrointestinal burns, mucous membrane erosion, bleeding and shock.
Enter the route: inhalation, swallowing.
Health hazard: This product is extremely irritating and corrosive. Dust or smoke can irritate the eyes and respiratory tract, corrode the nasal septum, direct contact between the skin and the eyes, and sodium hydroxide can cause burns. Eating can cause gastrointestinal burns, mucous membrane erosion, bleeding and shock.
The product will not burn. When it meets water and steam, it will release a lot of heat to form a corrosive solution; it will neutralize with acid and release heat; it is corrosive and harmful to the environment.
Combustion (decomposition) products: May produce harmful toxic fumes.
Folding leaks:
Isolation of leaking contaminated areas with warning signs around them. It is recommended that emergency personnel wear gas masks and chemical protective clothing. Do not touch the leak directly. Collect it in a dry, clean, covered container with a clean shovel, add a small amount of NaOH to a large amount of water, adjust to neutrality, and place it in the wastewater system. It can also be rinsed with a large amount of water, and the diluted wash water is placed in the waste water system. Such as a large amount of leakage, collection, recycling or harmless treatment.
Fold protection.
Respiratory protection: Wear a respirator if necessary.
Eye protection: Wear chemical safety glasses. Protective clothing: Wear overalls (made of anti-corrosion materials). Use with care and carefully spill into clothing, nose and mouth.
Hand protection: Wear rubber gloves.
Other: After work, take a shower and change into clothes. Pay attention to personal hygiene.
Folding first aid measures:
Skin contact: first rinse with water (lean liquid) / cloth (paint), then wash with 5~10% magnesium sulfate or 3% boric acid solution, and consult a doctor.
Eye contact: Immediately apply eyelids and rinse with 3% boric acid solution. Seek medical assistance.
Inhalation: Move quickly from the field to fresh air. Perform artificial respiration if necessary. Seek medical assistance.
Ingestion: When eating a small amount of food, immediately neutralize with vinegar, 3~5% acetic acid or 5% dilute hydrochloric acid, a large amount of orange juice or lemon juice; quickly give egg white, milk or vegetable oil, and seek medical advice quickly to avoid vomiting and gastric lavage.
