Boric Acid (chemical formula: H₃BO₃) is an inorganic compound and is classified as a hazardous chemical. It appears as a white crystalline powder with a slippery feel and is odorless. It is widely used in the pharmaceutical industry, but since it is a dangerous chemical, care must be taken when handling it. Its CAS number is 10043-35-3.
What are the main applications?
Industrial ：Boric acid is widely used in glass production, especially in the manufacture of heat-resistant glass, optical glass, and fiberglass. The addition of boric acid improves the heat resistance and chemical resistance of the glass.
Agricultural ：Boron is an essential micronutrient for plant growth. Boric acid is commonly used as a fertilizer to supplement the boron content in the soil. Boron helps promote flowering, fruiting, and root development in plants.
Household ：Boric acid has insecticidal properties and is often used to control pests like cockroaches and ants. It is effective in eradicating these pests.
Pharmaceutical ：Boric acid solutions are commonly used as skin disinfectants for treating minor wounds, skin infections, or eye infections. It has mild antibacterial properties, helping to reduce inflammation and promote healing.
What first aid measures should be taken when encountering danger on different occasions?
Inhalation Exposure
Quickly move to an area with fresh air. Keep the airway open. If breathing is difficult, administer oxygen. If breathing or heartbeat stops, immediately perform CPR and seek medical attention.
Skin Contact
Immediately remove contaminated clothing and wash the skin thoroughly with flowing water. Seek medical attention.
Eye Contact
Immediately separate the eyelids and wash the eyes thoroughly with flowing water or saline solution. Seek medical attention.
Ingestion
Rinse the mouth and drink water. Seek medical attention immediately.
Therefore, boric acid is a useful but potentially hazardous chemical. By taking appropriate safety measures, such as wearing personal protective equipment, following usage instructions, keeping it away from children and pets, and properly handling leaks and emergency situations, the health risks associated with boric acid can be effectively minimized.
