What are the hazards of lithium hydroxide to the human body

Lithium hydroxide (LiOH) is a 1 strongly alkaline compound that is highly corrosive to the human body and may cause serious injury through skin contact, inhalation or ingestion. Its harm is mainly manifested as chemical burns, respiratory tract injury, digestive tract corrosion, long-term contact may also cause chronic inflammation or organ damage.

1. Hazards of skin contact

When lithium hydroxide comes into contact with the skin, it reacts rapidly with oil and moisture, disrupting the skin barrier and causing redness, pain, blisters or ulcers. If it is not treated in time, it may cause deep tissue damage and even leave permanent scars. The risk of burns increases significantly when high concentrations of lithium hydroxide solutions or solids are in direct contact.

2. Hazards of inhalation of dust or droplets

Lithium hydroxide dust or solution droplets are inhaled, will stimulate the respiratory mucosa, causing cough, sore throat, difficulty breathing and other symptoms. In severe cases, it may cause chemical pneumonia or pulmonary edema, especially when prolonged exposure to or inhalation of high concentrations of substances in confined spaces.

3. Hazards of accidental ingestion or exposure to the digestive tract

Misuse of lithium hydroxide can severely corrode the mucous membranes of the mouth, esophagus and stomach, causing severe pain, nausea, vomiting, and even gastrointestinal bleeding or perforation. Even small amounts may cause metabolic alkalosis and require immediate medical attention.

4. the potential risks of long-term exposure

Long-term exposure to low concentrations of lithium hydroxide may cause chronic dermatitis, respiratory inflammation, or affect liver and kidney function through skin absorption. Animal experiments have shown that excessive lithium ion accumulation may interfere with the nervous system, but the data of human research are limited.

5. emergency treatment and protective measures

Skin contact: Rinse immediately with plenty of water for more than 15 minutes to remove contaminated clothing and avoid rubbing the affected area.

Inhalation: Quickly transfer to fresh air, keep breathing unobstructed, if necessary, oxygen or medical attention.

Misuse: no vomiting, immediately drink milk or water dilution, and sent to a doctor for professional treatment.

Daily protection: Wear chemical protection gloves, goggles and dust mask during operation to avoid direct contact.

6. special population risk warning

Pregnant women, children and people with respiratory diseases are more sensitive to lithium hydroxide. If persistent dizziness, chest tightness or abnormal skin discoloration occurs after exposure, it is necessary to be alert to the possibility of systemic poisoning and medical intervention should be carried out as soon as possible.

The toxicity of lithium hydroxide is closely related to its concentration, contact time and individual differences. Safety regulations shall be strictly observed in industrial production or laboratory use, and scientific treatment measures shall be taken in time after personal contact to avoid secondary injury.
