The use of benzalkonium chloride requires special attention to the following safety measures:
1. Protective gear: Operators should wear appropriate protective gear such as gloves, protective glasses and clothing to avoid direct contact with skin and eyes.
2. Avoid inhalation: Benzalkonium chloride may produce irritant gases, especially at high concentrations. Good ventilation should be ensured to avoid inhalation.
3. Avoid oral administration: Benzalkonium chloride is toxic and should be avoided. If accidentally swallowed, seek medical attention immediately.
4. Avoid contact with eyes: Benzalkonium chloride is a strong eye irritant and contact with eyes should be avoided. In case of inadvertent contact, flush immediately with plenty of water and seek medical attention.
5. Avoid contact with skin: Benzalkonium chloride is corrosive to the skin and prolonged contact should be avoided. In case of skin contact, flush immediately with plenty of water and seek medical attention.
6. Avoid contact with organic matter: The bactericidal effect of benzalkonium chloride is significantly reduced when it comes into contact with certain organic matter (e.g. blood, cotton, cellulose).
7. Avoid mixing with soaps and detergents: Benzalkonium chloride should not be mixed with soaps, salts, or other synthetic detergents as this may reduce its bactericidal effect.
8. Avoid use on sensitive materials: Benzalkonium chloride should not be used to sterilize soft corneal contact lenses, ophthalmic instruments, and synthetic rubber products as this may damage these materials.
9. Avoid storage in PVC containers: aqueous solutions of benzalkonium chloride should not be stored in PVC containers as they may react with the plasticizer in the container and reduce its effectiveness.
10. Avoid prolonged repeated use: Prolonged or repeated use of benzalkonium chloride may cause allergic reactions and should be avoided.
11. Dispose of waste properly: Benzalkonium chloride solution after use should be disposed of properly in accordance with local regulations and guidance to avoid pollution of the environment.
12. Storage conditions: Benzalkonium chloride should be stored in shaded, airtight containers away from direct sunlight and high temperatures.
By following these safety measures, the risks associated with the use of benzalkonium chloride can be minimized.
