Boric Acid

Boric acid, also known as hydrogen borate, is a weak acid derived from boron and often appears as a colorless or white crystalline solid or powder. It is soluble in water and has a slightly greasy feel. Boric acid is widely used for its antiseptic, antifungal, and insecticidal properties, making it useful in a variety of industrial, household, and medical applications.

Applications

• Medical and Pharmaceutical:
  • Used as an antiseptic for minor cuts, burns, and infections. It is also used in eyewash solutions and ointments to treat eye infections and other irritations.
• Insecticide:
  • Commonly used as an insecticide for controlling pests like ants, cockroaches, and termites. It acts by disrupting the insect’s metabolism when ingested.
• Industrial Applications:
  • Employed in the manufacture of glass, ceramics, and fiberglass, where it helps in controlling viscosity and improving thermal and chemical resistance.
  • Used in the production of borosilicate glass, which is resistant to thermal shock and chemical corrosion.
• Household Uses:
  • Boric acid is found in household products like antiseptics, detergents, and cosmetics. It is also used as a preservative in certain foods and in pest control products.
• Laboratory Reagent:
  • Utilized as a buffering agent in laboratories to maintain pH in chemical solutions and as a reagent in various analytical procedures.
• Nuclear Power:
  • Used in the nuclear power industry as a neutron absorber to control the fission process in nuclear reactors.

Handling and Safety

• Handling:
  • Use appropriate personal protective equipment (PPE) such as gloves, safety goggles, and protective clothing to avoid direct contact with skin and eyes.
  • Handle in a well-ventilated area to avoid inhalation of dust.
  • Avoid generating dust and ensure that all handling processes minimize airborne particles.
• Storage:
  • Store in a cool, dry, and well-ventilated place, away from moisture and incompatible substances such as strong bases.
  • Keep containers tightly closed to prevent contamination and moisture absorption.
• Safety Precautions:
  • Inhalation: Inhalation of dust may cause respiratory irritation. Move to fresh air immediately and seek medical attention if symptoms persist.
  • Skin Contact: May cause skin irritation, especially with prolonged exposure. Wash thoroughly with soap and water if contact occurs.
  • Eye Contact: Can cause eye irritation. Rinse immediately with plenty of water for at least 15 minutes, and seek medical attention if irritation persists.
  • Ingestion: Harmful if swallowed in large quantities. May cause nausea, vomiting, and abdominal pain. Seek immediate medical attention if ingested.
• Disposal:
  • Dispose of in accordance with local, regional, and national regulations. Avoid release into the environment. Boric acid is generally considered non-hazardous, but it should still be disposed of properly to prevent environmental contamination.

First Aid Measures

• Inhalation: Move to fresh air immediately. Seek medical attention if breathing difficulties occur.
• Skin Contact: Wash skin thoroughly with soap and water. Remove contaminated clothing.
• Eye Contact: Flush eyes with water for at least 15 minutes. Seek medical attention if irritation persists.
• Ingestion: Rinse mouth with water. Do not induce vomiting unless instructed by medical personnel. Seek immediate medical attention.
