Sol. Sodium hypochlorite (1% solution) is the recommended disinfectant to decontaminate HIV-contaminated articles or surfaces, as per WHO and CDC guidelines. It is fast-acting, cost-effective, and commonly used in hospitals for cleaning blood spills, syringes, and equipment. Other agents like glutaraldehyde are also effective but used in specific sterilization protocols.
Explanation of each option:
· (a) Formaldehyde – Incorrect. While it is a strong disinfectant, it is toxic, carcinogenic, and not routinely used for surface disinfection in clinical practice.
